[0069] In order to solve the problems of the existing methods, it can deal with the deformation of the large motion of the three-dimensional target object. For this reason, the solution adopted by the present invention is a global non-rigid registration method based on sparse representation. Suppose there is a model with n perspectives, denoted as U 1 ,U 2 ,...,U n . For any model p, N is the number of points of model p; is the point homogeneous coordinates of . For a pair of adjacent models U p , U p+1 (for the last model U n , adjacent to which is U 1 ), using artificial or corresponding algorithms (such as "Tam G K L, Martin R R, Rosin P L, et al. Diffusionpruning for rapidly and robustly selecting global correspondences using localisometry[J].Acm Transactions on Graphics,2014,33(1) :57-76.”) Find the initial mapping relationship f between them p→p+1 , that is, the corresponding points, and then solve the non-rigid transformation X between them p , is a 3*...
