| Abstract: | 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. |
