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 ...
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 ...
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. ...
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. ...
Survey Configuration for Terrestrial Laser Scanning: Aufnahmekonfiguration für Terrestrisches Laserscanning
(2016)
Despite the enormous popularity of terrestrial laser scanners in the field of geodesy and related sciences the vital task of viewpoint planning is mostly considered intuitively. In contrast to established acquisition ...

(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 ...
Spatio-temporal Correlations of Terrestrial Laser Scanning: Raumzeitliche Korrelationen beim terrestrischen Laserscanning
(2016)
This contribution investigates correlations in terrestrial laser scanning on the scientific level. It summarizes recent approaches to model correlations, to develop measurement scenarios for the determination of correlations ...
Optimizing the Target-based Calibration Procedure of Terrestrial Laser Scanners: Optimierung des zielzeichenbasierten Kalibrierprozesses terrestrischer Laserscanner
(2020)
Terrestrial laser scanner (TLS) measurements suffer from systematic errors due to internal misalignments. The magnitude of the resulting errors in the point cloud exceeds the magnitude of random errors in many applications. ...
