| Summary: | In this paper, a three steps segmentation approach is proposed in order to create 3D models from point clouds acquired by TLS
inside buildings. The three scales of segmentation are floors, rooms and planes composing the rooms. First, floor segmentation is
performed based on analysis of point distribution along Z axis. Then, for each floor, room segmentation is achieved considering a
slice of point cloud at ceiling level. Finally, planes are segmented for each room, and planes corresponding to ceilings and floors are
identified. Results of each step are analysed and potential improvements are proposed. Based on segmented point clouds, the
creation of as-built BIM is considered in a future work section. Not only the classification of planes into several categories is
proposed, but the potential use of point clouds acquired outside buildings is also considered. |
