The traditional measurement method using pitch instrument has low efficiency and its accuracy needs to be improved.In order to accurately obtain the deformation of marine propeller,a method using 3D laser scanner to measure and analyze its deformation is proposed.After obtaining the 3D laser point cloud data from multiple perspectives,the pre-pro-cessing of clipping and de-noising is carried out first,and then the point cloud is processed by the improved SAC-IA coarse splicing and ICP fine splicing accelerated processing of K-D Tree,and the accuracy of the splicing is analyzed.Then the sim-ulation model based on the point cloud is compared with the original design model in CATIA software.The direct and spe-cific deformation of marine propeller is obtained,which verifies the feasibility of this method.
