摘　　要：介绍了基于平面拟合后假设检验方法进行形变探测的算法,提出了逐级划分点云的方法,利用试验数据实现了最佳划分方案探测,提高了形变探测效率,并在最后一级划分中提取出形变量。We put forward a method for partitioning the point clouds of two epoches step by step into smaller grid areas each time to improve deformation detection efficiency.The deformation location is detected precisely to a large extent through plane fitting and hypothesis-testing.At last,the deformation quantitative is obtained through interpolation in the last level of partition.
