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 ...
Towards the Development of a Continuous Spatio-Temporal Finite Element Based Representation of the Mean Sea Surface
(2022)
The mean sea surface has an important role both in the calculation of the mean dynamic topography and in the area of sea level change as a reference surface. This paper presents a new approach to estimate a continuous ...
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, ...
High-Precision Surface Inspection: Uncertainty Evaluation within an Accuracy Range of 15μm with Triangulation-based Laser Line Scanners
(2014-01-02)
Triangulation-based range sensors, e.g. laser line scanners, are used for high-precision geometrical acquisition of free-form surfaces, for reverse engineering tasks or quality management. In contrast to classical tactile ...
Visual Place Recognition in Changing Environments
(2020)
Localization is an essential capability of mobile robots and place recognition is an important component of localization. Only having precise localization, robots can reliably plan, navigate and understand the environment ...
Visual Odometry and Sparse Scene Reconstruction for UAVs with a Multi-Fisheye Camera System
(2020)
Autonomously operating UAVs demand a fast localization for navigation, to actively explore unknown areas and to create maps. For pose estimation, many UAV systems make use of a combination of GPS receivers and inertial ...
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2020)
Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ...
