Abstract :
In this paper a novel approach for 3D reconstruction of buildings by combining aerial imagery and laser data is presented. In a precalculation process a first coarse approximation is calculated on the basis of the height data. The main processing step of the method refines this approximation by successfully making use of both the height data and the aerial images in a single energy minimization process.
