英文摘要：

On the basis of existing related theory, this paper placed emphasis on sampling strategy and determination of the matching point set of ICP algorithm. Firstly,the overlap area was determined and the point on the boundary was recognized. Secondly, sampling in the overlap area, and took differ- ent sampling strategies in different stages of the iteration of ICP algorithm. At the same time,this pa- per presented a new way to determine the match point set to guarantee the precision and increase the speed of the fine registration. Finally, experiments based on the point data verified the effectiveness and practicability of the algorithm.
