Dealing with systematic laser scanner errors due to misalignment at area-based deformation analyses
(2018-03-07)
The ability to acquire rapid, dense and high quality 3D data has made terrestrial laser scanners (TLS) a desirable instrument for tasks demanding a high geometrical accuracy, such as geodetic deformation analyses. However, ...
Geodäsie und Quantenphysik
(2007)
Im Jahr 1880 äußerte HELMERT fest, "Geodäsie ist die Wissenschaft von der Ausmessung und Abbildung der Erdoberfläche". Mit diesem Zitat werden viele geodätische Arbeiten begonnen, und auch für den vorliegenden Beitrag ...
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 ...
Gravity Field Refinement by Radial Basis Functions from In-situ Satellite Data
(2008)
In this thesis, an integrated approach is developed for the regional refinement of global gravity field solutions. The analysis concepts are tailored to the in-situ type character of the observations provided by the new ...
Digital Filtering Algorithms for Decorrelation within Large Least Squares Problems
(2008)
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 ...
A New Approach for a Kinematic-Dynamic Determination of Low Satellite Orbits Based on GNSS Observations
(2008)
A new approach for the integrated kinematical-dynamical orbit determination of low flying satellites based on high-low GPS-SST observations is proposed. These observations are code and carrier phase measurements between ...
Algebraic, logical and stochastic reasoning for the automatic prediction of 3d building structures
(2021-01-26)
3D building models are nowadays an important prerequisite for many applications such as rescue management or navigation tasks. However, most approaches for the automatic reconstruction of buildings rely on high-resolution ...
Plant Classification Systems for Agricultural Robots
(2021-03-16)
Due to a continually growing world population, the demand for food and energy increases continuously. As a central source of food, feed, and energy, crop production is therefore called upon to produce higher yields. To ...
Exact Optimization Algorithms for the Aggregation of Spatial Data
(2020-12-16)
The aggregation of spatial data is a recurring problem in geoinformation science. Aggregating data means subsuming multiple pieces of information into a less complex representation. It is pursued for various reasons, like ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012-07-18)
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 ...
