Modeling the Beam Deflection of a Gantry Crane under Load
(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 ...
Aiming at self-calibration of terrestrial laser scanners using only one single object and one single scan
(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 ...
Flächenhafte Deformationsanalysen mit terrestrischen und Nahbereichslaserscannern: eine Gegenüberstellung anhand von Beispielen
(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 ...
Biased and unbiased estimates based on laser scans of surfaces with unknown deformations
(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, ...
