摘　　要：以三维扫描数据为基础进行的人体重构,需要先进行数据精简.通常的精简过程需要对庞大数量的网格面片进行计算,而且还要记录网格之间的拓扑关系,时间和空间复杂度都很大.本文提出了一种不需要事先对扫描对象进行表面重构,而直接进行点云精简的方法,从而大大提高了点云精简的效率.Before handling the reconstruction of human model based on 3D scanning data, data reduction was used. The traditional method based on mesh reduction was complicated and time-consuming, because the topological relationships of the meshes needed to be recorded. This paper presented a convenient way to solve the problem. The data of cloud points were reduced before the object was reconstructed. Compared with the traditional method, the method presented in this paper not only reduced the arithmetic complication on space and time, but also preserved the charistic of the original object and finished the data reduction quickly.
