Entwicklung einer direkten Georeferenzierungseinheit zur Positions- und Orientierungsbestimmung leichter UAVs in Echtzeit
(2016-09-27)
Seit einigen Jahren werden im Bereich der Geodäsie immer häufiger auch Unmanned Aerial Vehicles (UAVs) als kinematische Trägerplattformen eingesetzt. Dazu werden diese mit objekterfassender Sensorik, wie z.B. Digitalkameras ...
Statistical relational learning of semantic models and grammar rules for 3D building reconstruction from 3D point clouds
(2016-11-04)
Formal grammars are well suited for the estimation of models with an a-priori unknown number of parameters such as buildings and have proven their worth for 3D modeling and reconstruction of cities. However, the generation ...
On High Performance Computing in Geodesy: Applications in Global Gravity Field Determination
(2014-12-08)
Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ...
Robot Mapping and Navigation in Real-World Environments
(2018-11-27)
Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ...
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2018-12-20)
Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ...
Analysis and mitigation of site-dependent effects in static and kinematic GNSS applications
(2019-10-08)
Satellitensignale unterliegen auf ihrem Weg von der Satelliten- zur Empfangsantenne einer Vielzahl an Einflüssen die zu Abweichungen führen. Heutzutage stellen in vielen Anwendungsbereichen insbesondere die stationsspezifischen ...
A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
(2019-04-18)
Continental water storage and redistribution within the Earth’s system are key variables of the terrestrial water cycle. Changes in water storage and fluxes may affect resources for drinking water and irrigation, lead ...
