English abstract:
In this paper, we present a method for the automated generation of 3D building models from directly observed point clouds generated by LIDAR. First, building regions are detected automatically. After that, we detect roof by applying a curvature-based segmentation technique. These roof planes are grouped in order to create polyhedral building models. In this grouping process, the shapes of the roof plane boundaries are determined, and the whole model is improved by an overall adjustment using all available sensor information and, if possible, geometric constraints. We describe the existing modules and those still in the implementation phase, and we discuss the issue of integrating aerial images into the reconstruction process to increase the geometric quality of the reconstructed models. We present intermediate results from a test site located in the City of Vienna, Austria.
