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 ...
One-Time Acidification of Slurry: What Is the Most Effective Acid and Treatment Strategy?
(2021-06-28)
Acidification of slurry is a common practice to reduce ammonia and methane emissions.
Sulfuric acid is usually used for this process. However, this has been criticized due to the high sulfur
input into soils. Therefore, ...
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 ...
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 ...
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. ...
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 ...
Sensoren für kinematische Anwendungen: Sensors for Kinematic Applications
(2014)
Dieser Artikel bietet einen Überblick über die Sensoren, die in kinematischen Anwendungen zur Bestimmung der Trajektorie einer bewegten Sensorplattform verwendet werden können. Dabei wird insbesondere darauf eingegangen, ...
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. ...
Heating Performance and Ammonia Removal of a Single-Stage Bioscrubber Pilot Plant with Integrated Heat Exchanger under Field Conditions
(2021-10-10)
In this study, biological exhaust air treatment was combined with a recuperative heat exchanger in one process stage. The aim of this plant development and testing is not only to reduce ammonia from the exhaust air of pig ...
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 ...
