Within the project, the Chair of Engineering Geodesy is responsible for the engineering geodetic monitoring of special hazard hotspots, such as Mt. Hochvogel (2592 m). The alpine measurement environment puts new demands on the monitoring system and the methods of deformation analysis. Specifically, research is being conducted on a method of rigorous deformation analysis based on point clouds without the need for signalized target points. Terrestrial Laser Scanning (TLS) can capture point clouds over the entire object with high accuracy. To date, evaluation has been limited to change detection. Real deformation vectors and information on the statistical significance of the detected movements cannot be derived due to the lack of identical points. A method under development at the chair solves this problem by retrieving prominent structures on rock faces using the Iterative Closest Point (ICP) algorithm, thus allowing identical points to be included in the rigorous deformation analysis. This can significantly increase the spatial resolution of high-precision 3D deformation vectors, even for inaccessible areas.
