Terrestrial Laser Scanning (TLS) for large objects and plants

The sigma3D team brings together terrestrial laser scanning (TLS) with many years of measurement experience for you: We create fast, flexible and efficient 100% complete 3D data of your buildings, halls, plants and machines!

From small cars to complete factories - terrestrial laser scanning enables us to measure all structures visible from the ground with a measuring point distance of up to 1.5 mm. The whole scanning process takes only a few minutes. For larger measuring ranges point clouds are linked together.

How does the measurement process work, what is measured?

While the scanner rotates 360 degrees, a rotating mirror captures up to 1 million points per second.
The result: a 1:1 image of reality in the form of a three-dimensional point cloud with millions of points. The accuracy is between 2 and 5 millimetres, depending on the nature of the object and the object distance.

Optionally, we can use a camera during the scanning process to create photorealistic 3D point clouds. This process creates an optimal visualization, as well as the possibility to explore 3D models virtually with VR glasses or browser.

Terrestrial laser scanning makes all further measurements superfluous: The 3D data completely captures the situation on-site and can be simply processed and above all, used without any limitations. This allows you to make planning, processes and visualizations efficient and accessible for your employees, partners and customers in the long term.

Application areas for terrestrial laser scanning

Our team has many years of practical experience and has already carried out successful measurement projects all over the world. Our customers come from all areas where surfaces and objects have to be measured precisely: For example, automotive, aircraft and mechanical engineering, power plants, the film industry, computer game development, property management, the construction industry, monument conservation and museums.

From the planning and simulation of constructions to the monitoring of construction progress and mechanical equipment and the preservation of evidence - terrestrial laser scanning offers you numerous advantages in a wide range of applications.


3D measurement

Terrestrial Laser Scanning (TLS) is the ideal replacement for the traditional hand measurement with a tape measure and plumb line:
We scan your object indoors and outdoors completely digitally and precisely - and you simply open your 3D model via your software and take your required dimensions at any time free of charge. A 3D measurement, also called digital measurement, ensures that nothing remains to unnoticed and you save time and money for the journey to the measuring location!

The 3D scans, as well as the image data, are viewed via an Internet browser in the Web share area ( so that different user groups can access the information quickly and easily if required.


Advantages of digital measurement:

  • Detailed and high-resolution recording of the asset inventory
  • Creation of plans based on 2D sections
  • Reconstructable representation of actual states
  • Further evaluations up to the CAD model
  • Of course, we are also happy to provide you with the point clouds in the common point cloud formats: RCS, RCP, FLS, POD, PTC, PTS, PTX, XYZ, E57, ...


3D system scan & as-built documentation

Whether machines, pipes or building parts - we scan complete factories and plants as 3D models for your documentation. Using mobile 3D laser scanning, we create precise point clouds with extremely high point density and transfer them into a CAD model via 3D modelling. We provide you with the captured data in the native data format of the standard CAD systems (AutoCAD, Catia, NX, Creo, SolidWorks, Inventor, or Me10, as well as in simple data formats (e.g. DXF, DWG, STEP)).


Building Information Modeling (BIM)

Building Information Modeling (BIM) enables architects, designers, engineers, manufacturers, CGI experts, developers, and contractors to work together to create a 3D building information model. The effect: Projects can be designed, constructed and managed more efficiently and accurately. Terrestrial laser scanning enables you to create a factually accurate foundation that captures and expands the dimensions of complex environments and geometries required for your BIM.

Digital Twin

3D scans offer a number of advantages when creating Digital Twins in the industrial or BIM sector.

    Accuracy: 3D scans provide highly accurate data that can be used to accurately represent the physical building in the Digital Twin.
    Time saving: Manual data capture can be time consuming. 3D scans enable rapid data capture, saving time and resources.
    Overview: 3D scans provide a comprehensive overview of the building structure, which is helpful for planning and implementing projects.
    Documentation: 3D scans serve as documentation for the current condition of the building and can be used later for comparisons and analyses.
    Collaboration: With digital twins, different stakeholders can access a common model and work together, regardless of their location.
    Problem solving: Digital twin makes it possible to identify and solve problems in the building on site before they lead to costly repairs.


Collision analysis & target-performance comparison

Terrestrial laser scanning is not only the ideal solution for checking the actual condition of components and complete systems: Complete 3D data also enable you to carry out realistic simulations for installation, conversion and transport. As a project manager, this allows you to optimally plan a collision-free and safe procedure - without losing time and money due to unforeseen complications.


Site plan measurement

If you need a 2D or 3D site plan, the measurement should be as precise and comprehensive as necessary. Do you want to plan a new plant in your old stock, or do you want to provide external companies with reliable plans? Based on our laser scans, we can quickly create site plans for you as simple point cloud sections or 2D/3D site plans in the form of CAD data. In this way, you can see at a glance where you can carry out conversions or optimize the use of premises.


Preservation of evidence

In the event of damage, it often proves to be very difficult to delimit construction-related damage. Our team can support you in an early independent evidence procedure with modern measuring methods and years of experience!

We carry out documentation of the construction status for you to identify construction defects before, during and after the acceptance of the construction. Terrestrial laser scanning enables us to combine exact geometric data with high-resolution image data as a means of preserving evidence.

This procedure provides you with an easily traceable and objective result. For example, different measurement epochs can be compared with each other via a graphically vivid 3D difference image.


Advantages for your preservation of evidence:

  • Digitized from zero hour
  • Secure evidence and prevent loss of evidence
  • Securing a judicial finding
  • Inhibit periods of limitation
  • Avoid legal disputes and settlements
  • Traceable and clear measurement results
  • More efficient follow-up measurements
