Dealing with systematic laser scanner errors due to misalignment at area-based deformation analyses 

Holst, Christoph; Medić, Tomislav; Kuhlmann, Heiner (2018-03-07)
The ability to acquire rapid, dense and high quality 3D data has made terrestrial laser scanners (TLS) a desirable instrument for tasks demanding a high geometrical accuracy, such as geodetic deformation analyses. However, ...

Empirical stochastic model of detected target centroids: Influence on registration and calibration of terrestrial laser scanners 

Medić, Tomislav; Holst, Christoph; Janssen, Jannik; Kuhlmann, Heiner (2019-03-22)
The target-based point cloud registration and calibration of terrestrial laser scanners (TLSs) are mathematically modeled and solved by the least-squares adjustment. However, usual stochastic models are simplified to a ...

Aiming at self-calibration of terrestrial laser scanners using only one single object and one single scan 

Holst, Christoph; Kuhlmann, Heiner (2014-12-05)
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 

Holst, Christoph; Nothnagel, Axel; Blome, Martin; Becker, Philip; Eichborn, Malwin; Kuhlmann, Heiner (2015-03-14)
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 

Jurek, Tobias; Kuhlmann, Heiner; Holst, Christoph (2017-07-19)
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 ...
