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 ...
Robust Wide-Baseline Stereo Matching for Sparsely Textured Scenes
(2013)
The task of wide baseline stereo matching algorithms is to identify corresponding elements in pairs of overlapping images taken from significantly different viewpoints. Such algorithms are a key ingredient to many computer ...
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 ...
Entwicklungsperspektiven metropolitaner Peripherien im Rahmen stadtregionaler Planungs- und Entwicklungsprozesse am Beispiel Nordrhein-Westfalen
(2013)
Die zurückliegenden Dekaden haben sich durch eine enorme Zunahme der Entwicklungsdynamiken von gesellschaftlichen, ökonomischen und ökologischen und daraus hervorgehend räumlichen Entwicklungen charakterisiert. Ein prägnantes ...
