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. ...
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 ...
Magnetic Field Sensor Calibration for Attitude Determination
(2014-05-29)
The presented work aims to give an overview of different calibration methods for magnetic field sensors,
which are used for attitude determination. These methods are applicable in the field without any additional equipment. ...
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 ...
Investigations on the Influence of Antenna Near-field Effects and Satellite Obstruction on the Uncertainty of GNSS-based Distance Measurements
(2016-03-31)
Antenna near-field effects are one of the accuracy
limiting factors on GNSS-based distance measurements.
In order to analyse these influences, a measurement campaign
at an EDM calibration baseline site with optimum
GNSS ...
Management support by optimization-based trade-off analysis: the example of biodiesel crop production
(2014)
Modeling in decision support applications has often been used to compare outcomes between alternative scenarios of decision options. The introduction of optimization methods enable the comparison of a very large number of ...
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
(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 ...
Direct Georeferencing for Portable Mapping Systems: In the Air and on the Ground
(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 ...
