Estimation of Focal Length Variations of a 100-m Radio Telescope's Main Reflector by Laser Scanner Measurements 

Holst, Christoph; Zeimetz, Philipp; Nothnagel, Axel; Schauerte, Wolfgang; Kuhlmann, Heiner (2012-08)
Due to gravitation, the main reflector of a radio telescope underlies a deformation which causes a change in focal length depending on the variations of the elevation angle of the telescope. In order to estimate these ...

Modeling the Beam Deflection of a Gantry Crane under Load 

Holst, Christoph; Burghof, Martin; Kuhlmann, Heiner (2014-02)
Gantry cranes load and unload containers from container ships. To ensure safety and operation, the deflection of their main beams under load should be analyzed. This deflection depends on the weight of the loaded container ...

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, ...

Accurate georeferencing of TLS point clouds with short GNSS observation durations even under challenging measurement conditions 

Zimmermann, Florian; Holst, Christoph; Klingbeil, Lasse; Kuhlmann, Heiner (2018-08-29)
The accuracy of georeferenced TLS point clouds is directly influenced by site-dependent GNSS effects, deteriorating the accuracy of the ground control point coordinate estimation. Especially under challenging GNSS ...

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 ...

Analyse der Konfiguration bei der Approximation ungleichmäßig abgetasteter Oberflächen auf Basis von Nivellements und terrestrischen Laserscans 

Holst, Christoph (2015)
Seit einigen Jahren unterliegt der Bereich der Ingenieurgeodäsie einem starken Wandel, da sich diese Disziplin generell den stetig weiterentwickelnden, anwendungsbezogenen Problemstellungen widmet. Unter diesen Aspekten ...

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 ...

Biased and unbiased estimates based on laser scans of surfaces with unknown deformations 

Holst, Christoph; Artz, Thomas; Kuhlmann, Heiner (2014-10-02)
The estimates based on laser scans of surfaces with unknown deformations are biased and not reproducible when changing the scanning geometry. While the existence of a bias is only disadvantageous at some applications, ...

Flächenhafte Deformationsanalysen mit terrestrischen und Nahbereichslaserscannern: eine Gegenüberstellung anhand von Beispielen 

Holst, Christoph; Dupuis, Jan; Paulus, Stefan; Kuhlmann, Heiner (2014)
Dieser Beitrag stellt einen Überblick über den Ablauf einer flächenhaften Deformationsanalyse basierend auf terrestrischen Laserscannern (TLS) dar, wobei speziell auf die Datenerfassung, Vorverarbeitung und Auswertung ...
