Abstract

This presentation describes the principle mechanisms how to compute position and attitude of an imaging sensor from a 3D landmark. A mission planning process provides data for the flightpath and appropriate descriptions of landmarks along the flightpath. The processing schemes as well as design considerations for a real time implementation are discussed. The processing consists of three levels. The image processing part extracts edge information from the image of a scene. The pattern recognition part solves the correspondence problem between the edges of the scene and a 3D wire model of the landmark by a relaxation matching operation. Photogrammetric methods finally are used in the pose estimation part. Nonlinear numerical optimization techniques are used to compute position and attitude of the sensor respectively the aerial vehicle.
