In order to establish physiological consistent correspondence between 3D facial skin for craniofacial recovery based on statistical model,a hierarchical correspondence method called HPCM is proposed.The sample face deforms based on thin plate spline according to strict correspondence of feature points in unified Frankfurt coordinate,so the sample face approximately coincides with the template.After voxel models are built respectively,the optimal point is determined by combining multiple constraints including Euclidean distance,local relative position and geometric features.Experimental results prove HPCM improves correct rate substantially and can establish physiological correspondence between 3D facial skin effectively.
