Ein Beitrag zur koordinatengesteuerten Aussaat von Rübenpflanzen mittels Multi-Sensor-System und Filteransatz
(2012)
Die Bestandspflege von landwirtschaftlichen Kulturen, maßgeblich geprägt durch die Unkrautkontrolle, wird heutzutage überwiegend mit chemischen Pflanzenschutzmitteln betrieben. Der gestiegene Bedarf an Bioprodukten erfordert ...
Vehicle Tracking and Motion Estimation Based on Stereo Vision Sequences
(2013)
In this dissertation, a novel approach for estimating trajectories of road vehicles such as cars, vans, or motorbikes, based on stereo image sequences is presented. Moving objects are detected and reliably tracked in ...
Empirical stochastic model of detected target centroids: Influence on registration and calibration of terrestrial laser scanners
(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 ...
Improved area-based deformation analysis of a radio telescope’s main reflector based on terrestrial laser scanning
(2015-03-14)
The main reflectors of radio telescopes deform due to gravitation when changing their elevation angle. This can be analyzed by scanning the paraboloid surface with a terrestrial laser scanner and by determining focal length ...
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 ...
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. ...
