Abstract
Systems and methods for generating building contours from point cloud data. The point cloud data is analyzed to identify one or more buildings. The contours of these buildings are then determined and these contours are decomposed into linear primitives. The results are then regularized and the final contours are generated from these regularized primitives. The contours can then be used in visualizations of building models.
