Terrestrial laser scanning (TLS) is the ideal replacement for the classic manual measurement with tape measure and plumb bob. With TLS, large areas from 1 to 150m can be recorded. For this purpose, the scanner generates a three-dimensional point cloud. This can then be used in a variety of ways.
The measurement is carried out with an accuracy between 2mm and 5mm, depending on the nature and size of the object. Due to the fast measuring method of laser scanning, all visible structures with a measuring point distance of 1.5 to 15 mm can be measured in a few minutes. The resolution is adjustable on the instrument and is additionally influenced by the measuring distance. Larger measuring ranges are measured by linking several scanner positions. With the optional acquisition of panoramic color images, the 3D scans can be colorized so that photorealistic 3D point clouds are obtained as a result.
When using the 3D scans recorded on site, you have the following options: Use the colored 3D point cloud for dimensionally accurate 3D visualization to understand and analyze complex local conditions. With a free viewer software the 3D data can be viewed on the PC and virtually inspected.
Do you want to plan a new plant into your old stock or do you want to provide external companies with reliable plans?
We will be happy to create meaningful 2D floor plans for your buildings or halls. We can provide you with these in common formats such as DXF, DWG as well as IGES and STEP. So you can see at a glance where you can carry out any conversions or whether you can still optimise the use of your premises.
Do you need precise documentation of your complete factory or plant?
With the 3D laser scanner, machines, pipes and building parts can be efficiently recorded as an exact point cloud and transferred to the CAD model via 3D modelling.
The created CAD data can be imported into all common CAD design programs. Either via simple data formats such as the STEP format or via CAD models in the native data format of common CAD systems such as AutoCAD, Catia, SolidWorks, Inventor, Me10, Pro/E, Solid, Solid Edge and Unigraphics.
The preservation of evidence in construction measures is carried out by a so-called independent evidence procedure.
The delimitation of damages caused by construction often proves to be extremely difficult in case of damage. This can be remedied by the timely introduction of measures to preserve evidence. Here a documentation of the building condition is accomplished. The procedure serves the determination of construction defects before, during and/or after the final inspection. The laser scanning measuring method allows exact geometric data as well as high-resolution image data to be combined as evidence preservation measures. The procedure delivers an easily comprehensible and objective result. Different measuring epochs can be compared with each other by means of a graphically descriptive 3D difference image. The 3D scans and the image data are viewed via an Internet browser in the Webshare area, so that different user groups can access the information quickly and easily if required.
The objectives of the preservation of evidence are:
Your complete production halls as a 3D model.
A great strength of laser scanning lies in the large number of points that can be determined in a high point density on the surface of an object. With the help of more suitable software, CAD models are created from these point clouds. For this purpose we provide the CAD data in the common file formats DXF, DWG as well as IGES and STEP.
Or use the data for Building Information Modeling (BIM). This enables architects, designers, engineers, manufacturers, CGI experts, developers and contractors to collaborate. By working with the same 3D building information model, projects can be designed, constructed and managed with greater efficiency and accuracy.
With the 3D measurement expensive mistakes can be avoided, so you can quickly find out with us whether your system will still run collision-free during future conversions.

With additional hardware (VR glasses), the user can view the captured data in a VR environment and move freely within it.
Another possibility of using 3D data is the creation of simple 3D objects by triangular meshing (3D mesh) of point clouds. The result is textured 3D models based on the scan data. The output is in OBJ data format from the scanner software.
The creation of CAD data from the point cloud. Here we are talking about "modelling", i.e. on the basis of the recorded actual data on site, CAD data is reproduced using construction software. The desired level of detail of the evaluation of the measurement data is determined via the parameter "Level-of-Detail" (LOD). Here it is determined how detailed the mapping of the measurement data into the CAD system should be. The effort and accuracy of the CAD model depends mainly on the level of detail.
