Research on the previous process for point cloud data based on surfacer software

The Study of previous process for Data "Point Cloud" includes the smoothing and the establishment of topology relationship. Reverse software-Surfacer is utilized to smooth the "point cloud". Then directly from space viewpoint and from general viewpoint, the approach to triangulation of the data "point cloud" is explained and the topology relationship between the data is established in the article. Finally, the next study is pointed out in the article.
