| Abstract: | Due to the huge number of scattered points generated in the process of laser scanning measurement, the curvature-based adaptive sampling strategy was presented and Delaunay-based triangulation method was implemented and an applied surface reconstruction algorithm which combines triangular Bezier patch modeling technique with NURBS modeling technique was studied. Aiming at the problem of range image registration, an improved iterative closest point (ICP) algorithm was adopted. |
