To solve the slow and long time-consuming problem of registration between dense cloud data and Computer Aided Design(CAD) model,a simplified point cloud data based rapid registration method of turbine blade was proposed.Based on three-dimensional optical scanning data and CAD model of turbine blade,point cloud data was simplified by using uniform sampling method and curvature sampling method.Through Singular Value Decomposition Interactive Closest Point(SVD-ICP) method,the rapid registration between turbine blade's dense cloud model and CAD model was realized,and accuracy as well as speed of registration were analyzed.The results indicated that the proposed method could increase the efficiency of registration without influencing registration accuracy.
