In times of steadily increasing traffic loads and extreme weather phenomena, the safe
maintenance of infrastructure poses a difficult challenge to operators, especially when a vast …

Terrestrisches Laserscanning wird in der Praxis bereits vielfach zur flächenhaften
Bestimmung von Bauwerksdeformationen genutzt. Es gibt jedoch kaum Ansätze zu strenger …

Terrestrial laser scanner measurements suffer from systematic errors due to internal
misalignments. The magnitude of the resulting errors in the point cloud in many cases …

For accurate astronomic and geodetic observations based on radio telescopes, the
elevation-dependent deformation of the radio telescopes' main reflectors should be known …

Mobile laser scanning has become an established measuring technique that is used for
many applications in the fields of mapping, inventory, and monitoring. Due to the increasing …

Time-of-flight depth cameras are interesting sensors for contact-less 3-D metrology because
they combine mechanical robustness with independence of ambient lighting conditions …

Terrestrial laser scanners (TLSs) have become indispensable for acquiring highly detailed
and accurate 3D representations of the physical world. However, the acquired data is …

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 …

To improve the positional accuracy of point-clouds, a self-calibration model of a terrestrial
laser scanner (TLS) was used to calibrate mounting angle errors as systematic errors. The …

Target-based calibration is the most widely used calibration procedure for terrestrial laser
scanners. Nevertheless, the current implementations of this procedure are suboptimal due to …
