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 ...
Finding spectral features for the early indentification of biotic stress in plants
(2013)
Early detection of biotic stress in plants is vital for precision crop protection, but hard to achieve. Prediction of plant diseases or weeds at an early stage has significant influence on the extent and effectiveness of ...
Lecture Notes from the Summer School of DFG SPP1257 Global Water Cycle: September 12-16, 2011, [Mayschoss/Ahr]
(2013)
In 2006, the German Research Association DFG had established the coordinated Priority Program SPP1257 Mass distribution and Mass Transport in the Earth System. According to DFG’s philosophy, SPP’s are meant to enable ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012)
Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ...
Digital filtering algorithms for decorrelation within large least squares problems
(2012)
The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ...
Attributierte Grammatiken zur Rekonstruktion und Interpretation von Fassaden
(2012)
Dem Bedarf und Nutzen hoch detaillierter 3D-Stadt- und Gebäudemodelle steht deren aufwendige Erfassung gegenüber. Ist die automatische Ableitung vereinfachter Dachstrukturen aus Luftbildern oder Laseraltimetrie weitestgehend ...
Visual SLAM from image sequences acquired by unmanned aerial vehicles
(2013)
This thesis shows that Kalman filter based approaches are sufficient for the task of simultaneous localization and mapping from image sequences acquired by unmanned aerial vehicles. Using solely direction measurements to ...
