Abstract

We introduce a pipeline that reconstructs buildings of urban environments as concise polygonal meshes from airborne LiDAR scans.It consists of three main steps : classification, building contouring, and building reconstruction, the two last steps being achievedusing computational geometry tools. Our algorithm demonstrates its robustness, flexibility and scalability by producing accurateand compact 3D models over large and varied urban areas in a few minutes only.
