Abstract

Extraction of the magnitude and direction of deformation is an important issue Deformation is typically extracted by comparing data related to a finite number of control point However such a method can only extract the magnitude of deformation but not the direction of deformation In this paper the improved ICP model is exploited for extracting the deformation The main idea of this method is the construction of improved ICP and the determination of the relationship between extraction of six deformation parameters and local matching This proposed deformation extraction method is particularly suited for scenarios where the deformation area is 3D rigidbody The performance of the proposed method is extensively evaluated numerically and experimentally according to the 3D rigidbody board deformation It is important to note that the conclusions were achieved under nonideal conditions eg using noncalibrated TLS point cloud and nonspecial targets Besides the simulation experiment the validation results achieved on bridge test site are briefly discussed
