Deformation Analysis Based on Terrestrial Laser Scanner Measurements (DFG FOR 5455)

Roads, bridges and dams are aging. How long can such structures be sustained? The new research group "Deformation Analysis with Measurements from Terrestrial Laser Scanners (TLS-Defo)" wants to take a step forward in answering these questions. The German Research Foundation (DFG) is funding the group with around 2.4 million euros over the next four years.

Before dams and bridges collapse, small deformations become apparent. If these small geometric changes can be detected at a very early stage, repair measures can be initiated in time to avoid closures or total failure. These "changes" take place in the range of a few millimeters or, in some cases, far below. Deformation analysis therefore evaluates whether the changes are truly changes in the object or a measurement inaccuracy.

This is the novelty of the research group: For the first time, a complete modeling of the measurement uncertainties of the terrestrial laser scanner is carried out for the use of the deformation analysis. This would provide an objective and efficient measurement method for deformation analysis.

In addition to the Chair of Engineering Geodesy at the Technical University of Munich, the University of Bonn, the University of Hannover, the Technical University of Vienna and the Karlsruhe Institute of Technology (KIT) are involved in the project.

The duration is from 01.11.2023 until 31.10.2027.

The Research Unit is funded by the DFG (German Research Foundation) under the number DFG FOR 5455.
