Abstract
In this work, a novel method for estimating the relative pose of a known object is presented, which relies on an application-specific data fusion process. A PMD-sensor in conjunction with a CCD-sensor is used to perform the pose estimation. Furthermore, the work provides a method for extending the measurement range of the PMD sensor along with the necessary calibration methodology. Finally, extensive measurements on a very accurate Rendezvous and Docking testbed are made to evaluate the performance, what includes a detailed discussion of lighting conditions.
In der Arbeit wird eine neuartige Methode zur Bestimmung der relativen Lage eines bekannten Objektes vorgestellt, welche auf einem anwendungsspezifischen Datenfusionsprozess basiert. Dabei wird ein PMD-Sensor zusammen mit einem CCD-Sensor benutzt, um die Lagebestimmung vorzunehmen. Darüber hinaus liefert die Arbeit eine Methode, den Messbereich des PMD-Sensors zu erhöhen zusammen mit der notwendigen Kalibrierungsmethoden. Schließlich werden detailierte und weitreichende Messungen aus einer sehr genauen Rendezvous und Docking-Testanlage gemacht, um die Leistungsfähigkeit des Algorithmus zu demonstrieren, was auch eine detaillierte Behandung der Beleuchtungsbedingungen einschließt.
