<p>This article presents a method for the automated generation of 3D building models from directly observed point clouds generated by Lidar. Building regions are detected automatically, and then a curvature-based segmentation technique detects roofs. These roof planes are grouped 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. The article describes the existing modules and those still in the implementation phase, and discusses the issue of integrating aerial images into the reconstruction process to increase the geometric quality of the reconstructed models.</p>
