Craniofacial reconstructing method based on hierarchical regression model
A regression model and hierarchical technology, applied in the field of forensic anthropology, can solve the problems that it is difficult to reflect the decisive role of craniofacial skin reconstruction, the craniofacial sample solution data is missing, and it is easy to fall into local minimal areas, etc., to achieve good reconstruction, High reconstruction accuracy and the effect of precise reconstruction

Embodiment Construction
[0027] The specific implementation of the craniofacial reconstruction method based on the hierarchical regression model of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] like figure 1 As shown, the main steps of the craniofacial reconstruction method based on the hierarchical regression model of the present invention include:
[0029] 1) Model training:
[0030] 1.1) Data processing: Perform non-rigid 3D data registration on the skull and skin in the training sample set, and normalize the posture and size of the skull and skin to obtain 3D skulls with the same number of vertices, the same semantics, and the same connection relationship. Grid model sample set and skin 3D mesh model sample set, and then from the 3D mesh model of each skin, the 3D mesh models of eyes, nose and mouth are divided, and finally each skull, skin, The 3D mesh models of eyes, nose, and mouth are normalized into a high-dimensional...
