| Abstract: | Point cloud data registration is one of the key steps in 3D laser scanning data processing.The paper uses different methods to carry out initial point cloud registration.The initial registration results provide ICP algorithm with initial position for precise registration.The experiment proves that the initial position has certain influences on the registration accuracy and speed.To improve the initial registration accuracy is one of the effective ways to solve the problem that ICP algorithm is easy to get stuck at the local optimal solution and its low efficiency. |
