| Abstract: | A method and steps of reconstructing geometrical model from threedimensional points cloud are studied.Two interactive methodssegmentation based on feature ideotification and segmentation based on projection and prone are presented for points cloud segmentation.Algorithm of boundary search from surface's points group and surface intersection algorithm are designed. A method segmentation and geometrical model reconstruction from 3D points cloud is studied and realized. |
