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 ...
Impact of spatial correlations on the surface estimation based on terrestrial laser scanning
(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 ...
Laser scanning based growth analysis of plants as a new challenge for deformation monitoring
(2016-03-31)
Nowadays, the areal deformation analysis has become an important task in engineering geodesy. Thereby, not only manmade objects are of high interest, also natural objects, like plant organs, are focused more frequently. ...
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 ...
Challenges and present fields of action at laser scanner based deformation analyses
(2016-03-31)
Due to improved laser scanning technology, laser scanner based deformation analyses are presently widespread. These deformation analyses are no longer based on individual points representing the deformation of an object ...
Accurate georeferencing of TLS point clouds with short GNSS observation durations even under challenging measurement conditions
(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 ...

(2019)
Terrestrische Laserscanner sind in der Lage, unsere Umgebung in Form von Punktwolken dreidimensional zu erfassen. Hierbei kann geräteintern in der Regel zwischen verschiedenen räumlichen Auflösungsstufen und auch ...
Overview on Current Modelling Strategies of Point Clouds for Deformation Analysis: Überblick aktueller Methoden zur Modellierung von Punktwolken für die Deformationsanalyse
(2016)
Terrestrial laser scanning was used for deformation monitoring of structures and geoscientific objects already at an early stage of its employment for engineering geodetic tasks. This paper gives an overview on current ...
Calibration of Terrestrial Laser Scanners: Kalibrierung terrestrischer Laserscanner
(2016)
The calibration of a laser scanner is necessary to reduce systematic errors in the acquired point cloud. Furthermore, calibrating laser scanners is motivated by the need of users to access up-to-date quality information. ...
Automatic optimization of height network configurations for detection of surface deformations
(2013-05-18)
Levellings are performed to observe height changes of different epochs at discrete surveying points. A
reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ...
