One common and important task in urban modeling is the extraction of 3D building geometry. Detecting and describing rooftops is a key step. We propose a building roof detection and description method using airborne LiDAR data and orthorectified aerial imagery. Our approach makes no presumption of the shape that a building rooftop should exhibit. We use… CONTINUE READING
