Kinematic Laser Scanning

In recent years, the acquisition of spatial 3D data by using mobile laser scanning systems has gained more and more acceptance. In this case, the environment is measured kinematically by using 2D laser scanners on moving platforms. The position and attitude of the platform is determined by using additional sensors like GNSS, IMUs or odometers. The resulting georeferenced 3D point clouds can be used for e.g. documentation, planning, monitoring and navigation purposes. The IGG Bonn is developing mobile laser scanning systems for different carrier platforms and with sensor technology reaching from low-cost and light-weight to high-end.

Portable Laser Scanning System

Mobile laser scanning system adapted to a van as carrier platform. The system consists of a terrestrial laser scanner operating in a profiling mode (Leica HDS 6100), an odometer (CorreVit) and a navigation-grade inertial navigation system (iMAR iNAV-FJI-LSURV).On the top of the van several GNSS antennas are used.
