Aiming at self-calibration of terrestrial laser scanners using only one single object and one single scan
When using terrestrial laser scanners for high quality analyses, calibrating the laser scanner is crucial due to unavoidable misconstruction of the instrument leading to systematic errors. Consequently, the development of ...
Improved area-based deformation analysis of a radio telescope’s main reflector based on terrestrial laser scanning
The main reflectors of radio telescopes deform due to gravitation when changing their elevation angle. This can be analyzed by scanning the paraboloid surface with a terrestrial laser scanner and by determining focal length ...
Impact of spatial correlations on the surface estimation based on terrestrial laser scanning
In terms of high precision requested deformation analyses, evaluating laser scan data requires the exact knowledge of the functional and stochastic model. If this is not given, a parameter estimation leads to insufficient ...
