Analysis of Different Reference Plane Setups for the Calibration of a Mobile Laser Scanning System
Heinz, Erik; Eling, Christian; Wieland, Markus; Klingbeil, Lasse; Kuhlmann, Heiner (2017)The discipline of engineering geodesy is currently subject to a paradigmatic change because the measuring of carefully selected single points is progressively replaced by an area-based acquisition of structures in form of ... -
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 ... -
Direct Georeferencing for Portable Mapping Systems: In the Air and on the Ground
Klingbeil, Lasse; Eling, Christian; Heinz, Erik; Wieland, Markus (2017-11)During the last few years, the acquisition of geometric information about objects by using a moving sensor platform has gained increasing popularity in the surveying community. A large number of companies offer vehicle-based ... -
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, ... -
Can we model the effect of observed sea level rise on tides?
Schindelegger, Michael; Green, Mattias; Wilmes, Sophie-Berenice; Haigh, Ivan (2018-06-07)The link between secular changes in the lunar semidiurnal ocean tide (M2) and relative sea level rise is examined based on numerical tidal modeling and the analysis of long-term sea level records from Europe, Australia, ... -
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 ... -
Zum Einfluss der räumlichen Auflösung und verschiedener Qualitätsstufen auf die Modellierungsgenauigkeit einer Ebene beim terrestrischen Laserscanning: The Impact of Spatial Resolution and Different Quality Levels on the Modeling Accuracy of a Plane Using Terrestrial Laser Scanning
Heinz, Erik; Holst, Christoph; Kuhlmann, Heiner (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 ... -
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 ... -
Optimizing the Target-based Calibration Procedure of Terrestrial Laser Scanners: Optimierung des zielzeichenbasierten Kalibrierprozesses terrestrischer Laserscanner
Medić, Tomislav; Holst, Christoph; Kuhlmann, Heiner (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. ...
