Airborne laser scanning has proven to be a strong basis for the automatic generation of 3D building models. A drawback, however, is often in the point spacing of typical datasets. As a consequence, the precision of roof plane and ridge line parameters is usually significantly better than the precision of gutter lines. To cope with problem the paper presents a novel approach for geometric refinement of building models reconstructed from ALS point clouds using single aerial imagery. The basis idea of our modeling approach it to obtain refined roof corners by direct intersection of 3D roof planes previously extracted from ALS data with viewing planes assigned with the edges detected in h...
