What Is a Browser-Based Point Cloud Viewer and What Does WebPano Do?

Created as a browser-based platform, it consolidates 360-degree panoramic views, point clouds, mesh models, 3D models and engineering data into a single, interactive environment that can be easily accessed by all project stakeholders. At its core, WebPano is a cloud-hosted viewer and collaboration platform designed specifically for scan and model data. Where traditional desktop engineering tools require installations on high-end hardware, WebPano runs on any web browser and is available to anyone with authorised access. Engineers, maintenance crews, designers and managers can access the same data set simultaneously from site, office or home.

Collaboration Made Easy

Traditional desktop-based engineering tools are inherently limited in how they can be shared. Sending a point cloud or 3D model typically means exporting a file, packaging it and hoping the recipient has the right software to open it. Comments and mark-ups exist only in proprietary formats and measurements are not always transferable. WebPano takes a fundamentally different approach. Everything is shared via a hyperlink; comments, measurements, markups and specific scan locations are instantly accessible to any authorised user, directly through their favourite browser. There is no data exchange process, no version control problem, and no delay while waiting for files to transfer. Users can communicate directly on WebPano via the comments feature, limiting the need for emails. In addition, no user limits mean the platform removes the bottleneck of licence-based access. A project team of five people and a client review group of twenty can all work from the same data simultaneously, without any additional cost, configuration or license swaps. For more examples on collaboration within WebPano, please see Planning with WebPano Visual Plant.

Intuitive Navigation

Navigating a complex project in a 3D environment can be time-consuming if you are scrolling and rotating to find specific areas. WebPano addresses this with tag and ID-based search: enter a component tag or identifier and WebPano will immediately highlight that object in the 3D model, panoramic view and the point cloud. This unified spatial context is extremely useful in practice. The ability to see how a component appears in the model, to view its real-world appearance in the panorama and confirm its accuracy to the point cloud — all from a single search — is something that conventional desktop tools simply cannot replicate without switching between multiple applications.

P&ID Integration: Connecting Schematics to Reality

A recent WebPano update focused on the integration of P&ID diagrams directly with 3D models and scan data. For most industrial facilities, P&IDs and 3D models exist as entirely separate documents and navigating between them requires cross-referencing by hand, which is slow and prone to error. In WebPano, a P&ID drawing can be linked directly to the spatial environment. Diagram elements that have been connected to their physical counterparts are highlighted automatically and creating a new link between a P&ID element and a 3D object takes only a moment. Once linked, navigation flows in whichever direction is most natural for the user: through the diagram, through the spatial view, or through list-based menus. Selecting any element immediately locates it in the plant, so schematic information and real-world context are always perfectly aligned. Critically, P&ID integration does not require a full 3D model to be present. Diagram elements can be linked directly to point cloud data, making this feature particularly valuable for brownfield sites and partially modelled facilities. For more details, see P&ID Integration in WebPano with 3D Models & Point Clouds.

Selective Data Sharing

When it comes to sharing data with external parties, WebPano allows each user to access only the relevant areas of the site, limiting the recipient to only view data that they require. This approach ensures that commercially or operationally sensitive areas of the site are not inadvertently included in data shared externally. Every stakeholder can access exactly what they need. To learn more, read our article on Scan Data Management for Industrial Projects.

A Smarter Approach to Digitalisation

A common concern when beginning a digitalisation programme is the scale of the upfront commitment. If every part of a site needs to be fully modelled before any value can be extracted, the cost and timescale can become prohibitive. WebPano removes this constraint by making panoramic views, meshes and point cloud data sets immediately useful without the need for a full intelligent 3D model. Inspections, HSE reviews, operational planning, and preliminary design work can all be carried out directly on scan data as soon as it is available. The result is a step-by-step approach to digitalisation: scan the plant, publish the data to WebPano, begin extracting value immediately, and build out the model incrementally. This significantly optimises the overall cost of digitalisation.

Workplace Safety and HSE Applications

WebPano’s spatial environment has direct applications for Health, Safety and Environment programmes. The platform supports the placement of safety markers and orientation signs within the digital environment, giving teams a realistic, browser-accessible reference for training and emergency procedures. WebPano can serve as the foundation for remote HSE training, risk assessment walkthroughs, and site induction — without the need to attend site. For a deeper look at how digital twins support modern HSE strategy, see our dedicated article Workplace Safety in the Era of Digital Twins.

Is WebPano Right for You?

WebPano is designed for projects that manage significant volumes of spatial data that need to be accessible across a broad group of stakeholders. If any of the following apply to your operations, it is worth exploring:

• Your team relies on specialist desktop software to view scan data or 3D models, creating bottlenecks when non-specialist staff need access.
• Sharing data with contractors or clients involves manual file exports, large transfers, or compatibility problems.
• Your P&ID drawings and 3D models exist in separate systems with no direct connection between them.
• You want to begin extracting value from scan data before a full 3D model has been built.
• You need to control precisely what point cloud data external parties can access.

Still unsure if WebPano fits your workflow? Watch our overview video to see all the key features in action: WebPano – Reality Capture and Spatial Data Platform | 3Deling

WebPano is developed and supported by 3Deling, alongside our laser scanning, 3D modelling and 2D documentation. If you would like to understand how it could work within your specific operational context, get in touch with our team to arrange a demonstration.

The post WebPano: An Overview appeared first on 3Deling - Experts in 3D Laser Scanning and Point Cloud Processing.

A customer that orders laser scanning services “to have documentation” will get something different from a customer that needs spatial data for a specific facility upgrade eight months down the line. The price will differ. The scope will differ. And, more importantly, the value of the data over the following years will differ.

What is Included in a Professional 3D Laser Scanning Service?

A 3D scanning service rarely ends with the scanning itself. A professionally executed project involves five interconnected stages and skipping any one of them has concrete technical and financial consequences.

Establishing a Control Network

This is the element clients most often overlook on their first project and subsequently feel the absence of throughout the project’s life span. The control network is a system of stable reference points embedded in a consistent coordinate framework for the entire facility. Without it, scans from different measurement campaigns are harder to merge accurately. Models created by different contractors in different years do not reference the same geometry. An industrial plant with a control network builds a cumulative spatial data asset. An industrial plant without one starts from scratch with every new project. More on this topic: Control Network — The Foundation of a Digital Twin of an Industrial Plant.

Laser Scanning: The Field Stage

In tender specifications, this stage is often described through parameters that are of secondary importance in practice. Maximum scanner range matters when scanning open spaces or tall structures, but in a dense industrial installation, scanner positions are set every 15–30 m, or even 3–5 m in extreme cases, because at greater distances pipelines and structural elements block each other and create “shadow” areas. Scan resolution is reduced during processing, and the final merged point cloud typically retains only 10–15% of the measured points. Excessive point density slows down work without improving model quality.

The parameter that truly determines data usability is the number of scan positions and the coverage planning for the facility. More scan positions from different directions and heights mean a more complete point cloud. Installation elements can be easily identified, and modelling proceeds without guesswork. Where there are few positions however — gaps appear and return visits to the site become necessary. For more on this topic, read: Data Quality in 3D Scanning: Why the Number of Scans Matters More Than Resolution

Point Cloud Registration and Quality Control

Scans from individual positions must be merged into a single coherent dataset anchored in a reference coordinate system. For small projects, this stage is relatively straightforward. In large industrial plants, where there are hundreds of scan positions, registration is the most demanding stage of the entire process — and yet, the easiest to get wrong. A registration that has been processed correctly produces a point cloud with documented accuracy: the report should include the maximum and average scan alignment error as well as the fit error to the control network. Without such a report, the client has no basis for assessing whether the data is accurate.

Data Delivery in the Required Format

The point cloud can be prepared for a specific working environment: Revit (RCS format), AVEVA E3D (LFM format), AutoCAD (RCS), or as the open E57 format recommended for long-term archiving and compatible with most CAD and CAE software. This distinction has practical significance: native files can be edited, converted, and handed over to future contractors. A company that doesn’t ask about the target working environment before signing a contract is probably not thinking about how the data will be used, only about how to collect it.

Data Access and Publication

A point cloud as a file on a drive is one option. Increasingly, the standard is to make scans, 360° panoramas, and models available in a web browser, so that designers, subcontractors, and maintenance teams can take remote measurements and verify installation details from anywhere, without installing specialist software or downloading large data sets. At 3Deling, this function is served by the WebPano platform, which becomes the central access point for a plant’s spatial documentation.

How Much Does Laser Scanning of an Industrial Plant Cost?

The price of the service depends on four variables worth understanding before speaking with a provider.

Floor Area, Volume, and Geometric Complexity

Area and complexity are not synonyms and for large industrial facilities, volume is a better indicator of project scope than floor area alone. A 10,000 m² production hall with open space and simple geometry is a different challenge from a petrochemical installation of similar area, where pipelines run across multiple levels, beams block sightlines, and every zone has restricted access. Complex geometry requires more scan positions, more registration time, and more quality control work.

Required Spatial Accuracy

For prefabrication of components and installation of new objects, registration accuracy at the level of a few millimeters is a technical requirement — a millimeter discrepancy between data and reality may only manifest as a problem during assembly. For collision detection or general plant inventory, tolerances are usually larger. Required accuracy directly affects control network density, the number of scan positions, and the registration method.

The Final Deliverable

A registered point cloud with WebPano access is one cost; a point cloud plus a solid CAD model in AVEVA E3D is another; and a fully intelligent installation model with technical attributes is yet another. It’s worth defining the goal before commissioning the project, not after. More on the strategy for selecting the right deliverable: Before You Commission a 3D Model — A Strategy That Saves Budget.

Logistics and Zone Accessibility

A plant operating continuously with restricted access to process zones requires different planning from a facility with unrestricted access. 3D laser scanning does not require halting production, it can be carried out during normal plant operation, but the schedule must account for access time slots and safety procedures.

5 Questions to Ask Your Provider Before Commissioning

Choosing a laser scanning company based solely on price is one of the most common mistakes on a first project. Here is what allows you to realistically assess the quality of an offer:

1. What is the estimated number of scanner positions for our facility? More positions mean fuller coverage and fewer data gaps. This is a better quality indicator than the declared scanner range or resolution.
2. Will the data be georeferenced to the plant’s coordinate system? Without a shared coordinate framework, data from different campaigns can still be aligned using cloud-to-cloud methods, but accuracy suffers, and each new project requires additional processing effort.
3. In what format will the data be delivered, and will we be free to use it as we see fit?
4. Does the provider supply a registration quality control report? A report with RMS error values and deviations at control network points is the only objective proof that the data has the declared accuracy.
5. Who stores the data after project completion, and for how long? An industrial plant point cloud is an asset that will be used for years to come. It’s worth knowing who holds it and under what terms.

When Does 3D Laser Scanning Deliver the Fastest Return?

The shortest payback periods are achieved in projects where scanning data is immediately built into an investment or maintenance process — not archived “for later.” A plant entering a maintenance shutdown with up-to-date spatial documentation eliminates costly contractor site visits, reduces the risk of design clashes, and shortens prefabrication lead times.

Based on data from our projects: for a medium-sized district heating plant, the return on investment in laser scanning and the WebPano platform is approximately 350% per year, with a payback period of under four months. We observe similar results in heavy industry plants, where precise spatial documentation eliminates design clashes and reduces the costs of site visits, with combined savings exceeding €250,000 per year.

The post 3D Laser Scanning: What’s Included in the Service and How Much Does It Cost? appeared first on 3Deling - Experts in 3D Laser Scanning and Point Cloud Processing.

The next step is data processing, and one of its most common outputs is the mesh model. This is the type of model most often used in presentations, web environments, and spatial analyses. At the same time, this is the stage where the quality achieved during data acquisition can easily be lost.

Before we go further, there’s one distinction worth making clear — one that causes confusion more often than you’d think: mesh is not CAD, and this difference has very real practical consequences.

A mesh model is a surface recorded as a network of polygons. Even a high-quality mesh remains a “net” — it carries a large amount of data, is difficult to edit directly, and without significant decimation can be too heavy to work with comfortably in CAD software. Its main advantage is low acquisition cost and faithful representation of physical reality.

A CAD model works on an entirely different principle: geometry described mathematically, lightweight, and fully editable. A well-built CAD model based on solid primitives can be imported directly into CAE environments such as AVEVA. The trade-off is time and effort — CAD modelling is a manual process, which makes it considerably more expensive.

Both approaches have their place and purpose — but they are not interchangeable.

A Mesh Model Does Not Appear “Out of Nothing”

A mesh model is created by connecting points into triangles that form continuous surfaces. To do this, algorithms must identify relationships between points and reconstruct surface continuity.

A key concept here is surface normals – vectors that define the orientation of a surface.

For a mesh to be accurate:

• the same areas must be captured from multiple viewpoints,
• the data needs to be geometrically consistent,
• surfaces cannot be defined from a single direction only.

This creates a direct dependency on how the data was captured. If scan coverage is insufficient, the mesh simply does not have enough information to reconstruct the geometry correctly.

Missing Data Doesn’t Go Away – It Gets Hidden

In a point cloud, missing data appears clearly as gaps.

In a mesh model, algorithms often attempt to fill these gaps by interpolating surfaces, closing geometry, and smoothing discontinuities. The visual result may appear coherent, but it does not guarantee geometric accuracy.

Mesh artifacts generated by reconstruction algorithms in areas with missing data – example on a roof surface

As a result:

• surfaces may appear where none exist in reality,
• details may be simplified or shifted,
• the model loses its value as a reliable data source.

For this reason, automatic hole filling should be used carefully and under control.

Point Cloud Cleaning – A Critical Step for Quality

Before generating a mesh model, the point cloud must be properly prepared.

This includes:

• removing noise,
• eliminating erroneous points (e.g., caused by moving objects),
• filtering out irrelevant elements.

This process is not fully automated in many cases and often requires manual work and experience.

If noise remains in the data, it will be embedded in the mesh as geometric artifacts.

Color and Texture – An Often Overlooked Quality Factor

Mesh models are often enhanced with textures, which significantly improve readability.

Textured mesh model of industrial installation – improved readability compared to non-textured geometry

However, texture quality depends heavily on capture conditions. Uneven lighting, harsh shadows, or changing weather can introduce inconsistencies.

The best results are typically achieved under uniform, diffused lighting conditions – for example, on an overcast day.

Texture resolution also needs to be carefully managed. Highly detailed textures can significantly increase file size without delivering proportional value.

Combining Data Sources – Laser Scanning and Photogrammetry

In many projects, the best results come from combining different data sources.

Laser scanning provides accurate geometry, while photogrammetry contributes high-quality visual detail. Photogrammetric images are usually captured within a short time frame and under consistent lighting conditions, often using higher-quality cameras than those built into scanners.

This results in more consistent and detailed textures, improving the overall readability of the mesh – particularly in areas that are difficult to scan.

Mesh generated from drone photogrammetry – high-quality textures and good results for simple building geometry

It is also worth noting that mesh models can be created entirely from photogrammetry, without laser scanning. This approach is widely used, especially for buildings and terrain.

It performs well for volumetric objects with relatively simple geometry, where flat surfaces such as walls and roofs dominate. In these cases, photogrammetry can deliver both good geometry and high visual quality.

However, for objects with complex geometry – such as industrial installations – its limitations become apparent. A high level of detail, cylindrical elements, occlusions, and irregular shapes make geometric reconstruction less stable and less reliable.

Mesh Optimisation – Finding the Right Balance

Raw mesh models can contain a very large number of triangles, which makes them difficult to work with.

To make them usable, optimisation is required, including:

• triangle reduction (decimation),
• geometry simplification,
• texture optimisation.

High-resolution mesh detail without textures – geometry is visible but harder to interpret visually

The goal is to strike a balance between detail and performance. A model that is too large becomes difficult to handle, while excessive simplification leads to loss of important information.

Mesh Quality Depends on Input Data

A mesh model can only represent reality as well as the input data allows.

Its quality improves with:

• the number and distribution of scans,
• completeness of object coverage,
• reduction of occlusions,
• consistency of the point cloud.

For large-scale objects with complex geometry or many occlusions, the model becomes more dependent on reconstruction algorithms. This may lead to artificially closed surfaces, geometric simplifications, and loss of interpretability.

Summary

A mesh model is a powerful tool, but its quality is not created during modelling.

It is determined by:

• how the data was captured,
• the quality of the point cloud,
• the completeness of the dataset,
• the processing workflow.

Decisions made at the beginning of a project ultimately define whether the final model is a reliable representation of reality or just a simplified approximation.

Factors Defining the Accuracy of Spatial Data

The accuracy of the final, registered point cloud is not a constant value. It results from the combination of technical parameters, measurement conditions, and the applied survey methodology.

1. Instrument Error

This results directly from the technical specifications of the laser scanner and includes:

• distance measurement error to the scanned object

• angular error (inaccuracy in determining the direction in which the laser beam is emitted)

• mechanical stability and calibration of the instrument

2. Registration Error (Scan Alignment)

This occurs during the process of combining consecutive scanner positions into a single consistent dataset. In large projects involving hundreds of scan positions, these errors may accumulate, resulting in the so-called drift effect—a gradual shift of geometry relative to the starting point.

3. Error in Georeferencing

This is related to assigning geodetic coordinates to the point cloud and placing it within a global reference system. The quality of this process depends directly on a properly designed control network for the facility—described in detail in our article:

Geodetic Control Network as the Foundation of Industrial Facility Digitalization.

Additional Factors Affecting Accuracy

• Scanning geometry: beam incidence angle, distance, and overlap between scan positions.
  This topic is discussed in more detail in the article:

Data Quality in 3D Scanning: Why the Number of Scans Matters More Than Resolution

• Atmospheric conditions: fog, rain, humidity, strong wind

• Surface properties: reflectivity, gloss, material type

• Number and quality of control points / targets

• Applied registration algorithm (target-based, feature-based, cloud-to-cloud)

• Station stability (vibrations, tripod settlement – often underestimated but critical)

Registration Methodology and Error Propagation

In professional 3Deling projects, the point cloud registration process is based on proprietary software developed specifically to minimize error propagation in large industrial projects. The system has been tested on more than 5,000 scanning positions.

The system provides:

• full control of the registration process

• automatic recognition of geometric objects

• integration of high-resolution panoramic images with point clouds, enabling better identification of installation elements and detailed analysis

• automatic algorithms for point cloud filtering

• a mobile application for marking scan positions in the field

• real-time data synchronization between users

• import and conversion of scans from various systems (including Leica, Faro, Z+F)

In practice, three main registration methods are used—often combined in a hybrid workflow.

Cloud-to-Cloud Method

(registration based on natural geometry)

This method automatically aligns scans by analyzing shared geometric features such as planes, edges, and characteristic shapes of pipelines or steel structures present in overlapping areas between scan positions. The algorithm aligns scans so that points from one scan overlap as closely as possible with points from another, calculating their relative rotation and translation to minimize distances between corresponding points.

Advantages

• high level of automation

• fast data processing

• effective in environments with rich geometry (e.g., historic buildings, office interiors)

Limitations

In large industrial facilities (e.g., linear installations longer than 100–200 m), a drift effect may occur, leading to accumulated linear error. Therefore, in the 3Deling software this method is supported by additional control points that stabilize the global geometry.

Feature-Based Method

(registration based on characteristic object shapes)

Feature-based registration aligns scans by detecting and matching geometric features such as planes and cylinders.

This method uses algorithms that detect planes and cylinders within individual scans. The detected shapes are then compared between neighboring scans and aligned. The algorithm recalculates the relative position of scans (rotation and translation) so that corresponding geometric features match as closely as possible, reducing alignment errors across the entire point cloud.

Advantages

• faster preliminary alignment of neighboring scans

• more stable in structured environments (e.g., industrial installations, production halls)

• particularly effective in areas with repetitive geometry (e.g., tank farms)

Limitations

This method requires clearly identifiable geometric features in overlapping scan areas. It is therefore less effective in environments with smooth, uniform surfaces such as plain walls, empty halls, or open terrain with few identifiable objects. Its accuracy is also limited by the precision of feature detection and identification within the scans.

Target-Based Method

(registration using reference targets)

This method uses circular targets or spherical markers placed within the facility. Their coordinates are measured using a total station and tied to the facility’s control network. As a result, the registration process is mathematically controlled, and the entire point cloud is stably embedded in the global coordinate system.

Benefits

• full mathematical control of the process

• possibility of achieving global accuracy of 2–5 mm under favorable conditions

• ideal for industrial projects requiring precise georeferencing

In the 3Deling system, this method is integrated with quality control procedures, allowing strict tolerances to be maintained even in very large projects.

Hybrid Approach – Control and Stability

Visualization of the scan connection network used in hybrid point cloud registration within 3Deling software.

Combining these methods helps eliminate the limitations of standard scanner software. This approach ensures high-quality and consistent point cloud data even in projects involving extremely large areas and thousands of scan positions.

The Role of a Control Network

For large industrial facilities such as refineries, chemical plants, power stations, or petrochemical complexes, establishing a control network covering the entire site is strongly recommended.

Using total station measurements of control points and tying them to the control network:

• anchors the point cloud in a global coordinate system

• prevents error accumulation between scans, eliminating drift

• maintains positional accuracy within a few millimeters

This is crucial for:

• installation of new equipment

• prefabrication of components

• clash detection analyses

• modernization of existing installations

Additionally, a geodetic control network enables scanning to be performed at different times (maintenance shutdowns, upgrades, deformation monitoring) while maintaining a consistent reference system. This makes it possible to build and update a complete as-built point cloud database for the entire facility over many years.

Quality Control and Reporting

The final point cloud undergoes multi-stage verification using proprietary 3Deling software. As part of the registration control process, the continuity and consistency of cross-sections and longitudinal sections are analyzed, and compliance with the defined accuracy requirements is verified.

Cross-section through a registered point cloud used to verify alignment accuracy and continuity between scans.

The registration report includes, among others:

• root mean square (RMS) error values for individual scan connections

• deviations at control network points

• translation and rotation errors for connections between scans (determined in global registration using control points and additional observations)

Transparency of these parameters forms the foundation of data reliability.

Summary

High accuracy of a registered point cloud is not merely a technical parameter. It represents real investment security and minimizes the risk of costly clashes during design, prefabrication, and installation.

Accurate as-built data ensures that:

• new installations fit perfectly into the existing environment

• modernization works proceed without unexpected conflicts

• project schedules and budgets remain under control

Thanks to the use of a control network and proprietary registration tools, 3Deling ensures that data remains consistent and stable for years—even across multiple scanning cycles and facility expansions.

What is Laser scanning?

Laser scanners capture millions of points by using laser time-of-flight or phase-shift to accurately measure distances. Millions of measurements are then transformed into a dense and highly accurate 3D point cloud. Think of it as capturing the “geometry” of a site with extreme precision. For a more in-depth guide, please see What Is Point Cloud Scanning?

What is Photogrammetry?

High resolution handheld or drone cameras capture hundreds, sometimes thousands of overlapping 2D photographs from many angles and transforms them into a 3D mesh of the space. Think of it as capturing the “appearance” of a site and deriving geometry from it. For a more in-depth guide, please see What Is Photogrammetry?

Laser Scanning: What is it good for?

The biggest advantage of laser scanning is the extremely high accuracy. It provides millimetre level accurate data making it ideal for structural analysis, MEP clash detection and other projects which require near perfect measurements. Laser scanners take direct measurements meaning it is almost completely immune to errors from lighting, surface patterns or camera. Laser scanners also work perfectly without any light; this makes them ideal for work in places like Mines or Tunnels. You can see real examples of our work in the Wieliczka Salt Mine and tunnel scanning projects in Sweden.

Photogrammetry: What is it good for?

The biggest advantage of photogrammetry is the low cost of entry. A high-quality professional drone and a high-resolution camera are significantly cheaper than a terrestrial laser scanner. If accuracy is not what you are after, even a smartphone can be used to collect the necessary 2D photographs that can then be processed into a 3D Mesh. What photogrammetry loses in accuracy, it gains in photorealism. This is invaluable for condition assessments, facade studies, architectural documentation, and creating visually compelling deliverables for clients. You can see cracks, material types, and colours directly. Photographs collected by drone can also record data in places that a laser scanner could not.

What to choose: Laser Scanning or Photogrammetry

What is the required deliverable accuracy?

For millimetre accuracy, Laser Scanning is the optimal choice – The direct measurements capture precise geometry ideal for structural analysis or clash detection. For centimetre accuracy, Photogrammetry is the way to go, achieving visually rich mesh models, perfect for condition reports and visualisations.

What is the environment?

Choose Laser Scanning for complex indoor spaces with shiny surfaces, glass, or low light. This method is far less susceptible to reflections or darkness. Drone photogrammetry, on the other hand, excels at large external topographies covering big areas of land. For close-range photorealistic detail, handheld photogrammetry is best.

What is the budget?

For high budgets, Laser Scanning delivers unmatched precision but requires expensive equipment and skilled operators. For limited budgets, Photogrammetry is the better choice. Consumer drones, cameras or even smartphones can be used to make quality 3D capture accessible at a fraction of the cost.

There is always the right tool for a job, and having the knowledge and expertise allows you to make the optimal choice. Analysing the most important factors for your project is key; Accuracy, cost, data file size and site conditions all need to be considered before making the choice between Laser Scanning or Photogrammetry. But there is a third option, the hybrid approach.

The Hybrid Approach

At 3Deling, we use a mixture of Laser Scanning, handheld and drone Photogrammetry, to get the best results for our clients. Point cloud data gathered by way of laser scanning can be processed with mesh date gathered by way of photogrammetry. This is the best of both worlds. It gives you the ability for extremely high accuracy in places where its required, with a photorealistic mesh. Years of experience using these methods give us the ability to advise you on what is the best fit for your project.

The post Laser Scanning Vs Photogrammetry: Which one is best for you? appeared first on 3Deling - Experts in 3D Laser Scanning and Point Cloud Processing.

In the previous article, we explained why a control network is the foundation of a reliable digital copy of an industrial plant and a prerequisite for long-term data consistency. However, this is only the first step. Equally important is how data is acquired in the field.

In 3D laser scanning practice, attention is still often focused on parameters that look good in technical specifications: maximum scanner range, very high resolution, or declared single-scan accuracy. Experience shows, however, that these parameters rarely determine the real usability of the data.

This article is based on the long-term experience of the 3Deling team and on observations gathered by Paweł Dudek, CEO of 3Deling, over nearly two decades of working with 3D laser scanning — from the first technology tests to large, complex industrial projects.

3d laser scanning field measurements

Early 3D Scanning Experiences – A Lesson in Humility

I remember the “tests” of our first scanner — it was 2007. We set a very high scanning resolution, because “it has to be dense” for the data to be good and for nothing to be missed. There was a slight surprise that a single scan would take around 30 minutes, but we waited for the result.

The scan finished, the data was transferred, then the point cloud was “processed” and opened in Pointools View (back then, it wasn’t Bentley Pointools yet). It took a while, but finally there it was — a very “heavy” scan. The data was visible at a very long distance. We could even see a chimney of a heating plant that no longer exists, located several hundred meters away. It was impressive.

This situation took place almost 20 years ago. At the time, each of us already had some experience with 3D laser scanning and we carried out such measurements on a regular basis. Looking from today’s perspective, however, it is clear how much we were still missing back then — especially when it comes to large-scale projects.

Today, our survey teams perform thousands of scans on a single site, all registered within one coordinate system, often under difficult conditions and time pressure. And in the end, only one thing really matters — that the client receives the best possible data.

Why We Scan Differently Today

In practice, the approach to scanning looks very different today. And it is not because we want to scan “fast and carelessly,” close the project and move on. Quite the opposite.

To obtain the most complete and usable geometric representation of an object, the key factor is the number of scans and their placement, not the maximum resolution or range of the scanner.

Scan Resolution – Why “Denser” Does Not Always Mean “Better”

Very dense scans are simply “heavy” datasets. They are harder to work with — both due to software limitations and hardware performance constraints.

That is why individual scans are often filtered and their resolution reduced. As a result, a unified point cloud can be five to six times lighter, while being much more convenient to use — without losing information that is actually relevant for design work.

Scanner Range – A Parameter Rarely Used to Its Full Extent

Most scanners we use have a range well above 100 meters — one of them even up to 600 meters. In practice, however, the data is usually used from much shorter distances:

• indoors: typically up to about 30 m,

• outdoors: typically up to about 50 m.

The full scanner range is rarely utilized and usually only in cases involving very tall structures with no safe physical access.

Completeness of the Geometric Representation – The Key Parameter

This is the most important data quality parameter — and at the same time one that can almost never be achieved 100%. There will always be so-called “shadows” or blind spots — areas with missing data.

However, these can be significantly reduced by performing a large number of scans from different positions, heights, and distances. With hindsight, it is clear that the number of scans is the key factor influencing the quality of the final geometric representation of an object.

Number of Scans and Real Design Work

We often support clients who are preparing for plant digitalization projects in drafting tender specifications. We then see that less experienced investors tend to focus primarily on parameters that look best “on paper”:

• range (the further, the better),

• resolution (the denser, the better),

• accuracy (ideally 1 mm).

We understand this — we used to think the same way ourselves. That is why we try to “demystify” these expectations and draw attention to what truly matters. And that parameter is the number of scans.

Where an object is well covered with scans, with many scan positions and a sensibly planned measurement geometry, subsequent modeling proceeds smoothly. The data is clear, there are no “holes,” elements can be interpreted unambiguously, and the model is created quickly — without guesswork.

In remote projects, for example in the Middle East, insufficient scan coverage becomes a serious issue very quickly. When data is sparse or scans are taken from unsuitable positions, modeling and design work based on point clouds turn into speculation. Information is missing, discontinuities appear, and it is unclear “what is what.” In extreme cases, such data is simply unusable.

Missing Data Means Real Costs

When data is incomplete, problems arise:

• returning to the site to perform additional scans,

• sending someone with a camera to take manual reference photos,

• accepting simplifications and uncertainties in the model.

Each of these options means additional time, cost, and risk of errors.

That is why, in practice, instead of performing a small number of very dense scans, we focus on a large number of scans with slightly lower resolution but good object coverage. This allows us to:

• obtain complete geometric data,

• minimize blind spots,

• create good conditions for modeling and design work,

• significantly reduce the time needed to interpret the data — designers do not have to guess what is where, because everything is already clear at the point cloud stage.

Unified Point Cloud and Working with Data

All scans are combined into a single unified point cloud, usually additionally filtered (e.g. to 5 mm). This unified cloud is used for 3D modeling and further design work.

At the same time, all individual scans with color information and panoramas are preserved and can be accessed at any time — for example via WebPano. This is a major advantage, especially for complex installations, where checking details, heights, and spatial relationships is crucial during design.

What to Look for in a Request for Proposal?

When selecting a 3D scanning provider, it is worth looking beyond hardware specifications.

Not only at:

• resolution,

• range,

• manufacturer-declared scanner accuracy.

But above all at:

• the estimated number of scans for the object.

This is one of the best indicators of the real quality of the data you will receive. A higher number of well-planned scans means fewer uncertainties, faster design work, and real savings in time and cost throughout the entire project lifecycle.

Summary

Resolution and scanner range are important, but they do not determine project success.
The number of scans and their placement have the greatest impact on the quality and practical usability of the final data.

Other important factors include the accuracy of the unified point cloud and a properly defined coordinate system — topics we will cover in the next articles of this series.

Planning 3D laser scanning or industrial plant digitalization?

If you want your data to be complete, consistent, and truly usable for design and engineering, the scanning strategy should be defined before any fieldwork begins.

At 3Deling, we help clients plan the number and placement of scans so that data quality translates into real time and cost savings throughout the project lifecycle.

However, for a digital twin of a plant to be reliable, consistent, and useful over the long term, one essential element is often underestimated at the planning stage: the control network.

Control network and distribution of 3D laser scanning positions within an industrial plant

What is a control network in the context of plant digitalization?

A control network is a set of stable reference points whose positions are precisely defined within an adopted coordinate system, together with information about their accuracy. In practice, it forms the physical reference framework to which all measurements within the plant are related.

In the context of digitalization, this means that the control network:

• defines the geometry and scale of the entire digital documentation,

• allows data from different laser scanning campaigns to be combined,

• enables the integration of point clouds, 3D models, and technical drawings.

Without a properly designed control network, even the highest-quality 3D laser scanning data loses much of its practical value.

Why is a control network critical for 3D laser scanning?

3D laser scanning generates vast amounts of data in the form of point clouds. For this data to be:

• combined into a coherent dataset,

• compared over time,

• used in modernization and expansion projects,

it must be referenced to a single, consistent coordinate system.

The same reference system can then be used not only for as-built surveys, but also for setting out newly designed objects in the field. This ensures that inventory data, design documentation, and construction activities all refer to the same control network, eliminating discrepancies between existing conditions, design intent, and actual positioning on site.

In practice, this significantly reduces interpretation errors, ambiguities in project positioning, and situations where responsibility for inconsistencies becomes blurred between the survey team, designers, and construction contractors.

The control network as the “skeleton” of a digital plant twin

The control network therefore acts as the structural backbone of a digital plant twin. Thanks to it:

• subsequent stages of digitalization can be implemented gradually,

• data collected over different years remains compatible,

• changes within the facility can be measured and clearly quantified.

This is particularly important in industrial plants, where digitalization is a long-term process, not a one-off project.

A local control network tailored to the digital plant

In industrial plant digitalization projects, a local control network is most commonly used. While it may be linked to a national coordinate system, it is optimized for the specific needs of the facility.

This approach offers tangible benefits:

• software used for point cloud processing and 3D modeling works most reliably when objects are described using low, positive coordinates, i.e. relatively small numerical values measured in meters from a local origin,

• the coordinate system can be aligned orthogonally with building and installation axes,

• data becomes more intuitive for designers, engineers, and maintenance teams.

A well-designed control network makes digital documentation easier to use and simpler to expand in the future.

Data stability today and in the future

One of the main objectives of plant digitalization is to preserve and organize technical knowledge, especially in the face of staff turnover and organizational change.

A control network:

• ensures consistency between historical and current data,

• enables comparisons of the facility’s condition at different points in time,

• provides a reference framework for future modernization, expansion, and analysis.

As a result, the digital plant twin is not a static archive, but an active tool supporting everyday technical decision-making.

The control network as the basis for integration with technical documentation

The full value of a digital plant twin emerges when 3D data is integrated with:

• CAD and CAE documentation,

• technological diagrams such as P&IDs,

• operational and maintenance information.

The control network enables this integration by ensuring that all elements refer to one consistent spatial reference system. This translates into:

• faster preparation of modernization projects,

• better communication with design companies,

• reduced risk of execution errors on site.

Summary: why digitalization should start with a control network

A control network is not an optional addition to plant digitalization—it is its foundation. It determines whether:

• data from different time periods remains compatible,

• point clouds become a practical design support tool,

• the digital plant twin remains useful for many years.

When planning 3D laser scanning and the creation of a virtual representation of an industrial plant, it is worth starting with a simple question:
Do we have a solid reference framework for all our data?

The control network is one of the key elements affecting data quality in the digitalization process, but it is not the only one. In the following articles, we will show how factors such as the number and distribution of scans, the accuracy of the registered point cloud, and the overall measurement strategy influence the practical usability of 3D data.
