%X In view of inconsistency between knee joint and prosthesis in spatial coordinate system, a three-stage registration method based on principal component analysis (PCA) and iterative closest point (ICP) algorithm is proposed, which adopts PCA and ICP twice. Firstly, the point cloud data of knee joint and joint prosthesis is registered by PCA. then ICP algorithm is used to adjust the initial registration results. Finally, ICP registration is carried out again for the adjusted point cloud data, so as to adjust its spatial coordinate axis to be consistent. Experiments show that compared with other algorithms, the three-stage registration method can keep high registration accuracy and shorten the registration time.
