Laser scanning

High-efficiency scanning
For volume calculations of waste heaps or for facade and industrial plant surveying we use a high-efficiency 3D-scanner. The RIEGL LMS-Z420i is able to measure up to 8000 points per second.

True-colour method
Surfaces are scanned line-by-line with a laser ray to generate a scatter-plot of the required resolution. A digital camera allocates one RGB-data per measured point. This procedure allows the scatter-plot to be displayed in true-colours. As a result of this, our customers get a very clear picture of what we have done.


Application areas:

  • waste heap surveying
  • facade scanning
  • industrial plants
 

To explain the procedure of laser scanning we use the waste heap surveying as an example:

After matching the modulated primary area [Picture 4] and the scanned surface you finally can calculate the waste heap volume [Picture 5]
