Aiming at establishing physiological consistent point correspondence between 3D faces, this paper proposes a new hierarchical correspondence method based on thin plate spline deformation called HCTD by introducing local geometric constraints. Firstly, mark feature points in unified Frankfurt Coordinate and the sample face deform based on thin plate spline function according to strict correspondences of feature points, so the sample face approximately coincide with the template; Secondly, build voxel models respectively and select vertexes with salient feature from the template as the current under-corresponding vertex, and the candidate set of the corresponding vertex on sample face is determined by local relative position geometric constraint and Euclidean Distance constraint. Finally, the optimal corresponding vertex is selected according to the weighted distance of local geometric features. Experimental results prove that HCTD can establish point correspondence of faces with higher precision than existing methods. |
