3d Building Model Generation from Airborne Laserscanner Data by Straight Line Detection in Specific Orthogonal Projections


The paper describes a novel approach for the generation of 3D building models from airborne laserscanner data, which is based on the detection of straight lines in specific 2D projections of the data. First, the main roof ridge directions of a building are determined. Based on these ridge directions, hypotheses on the roof orientation are generated. The… (More)
