Title:
3D HUMAN FACE RECONSTRUCTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/029768
Kind Code:
A1
Abstract:
The embodiments of the present application provide a 3D human face reconstruction method. The method comprises: acquiring an image for 3D human face reconstruction, and acquiring information of a preset number of image feature points serving as 3D human face reconstruction feature points from the image, the set of the image feature points being used to reflect the contour of a human face; acquiring a 3D average human face model; determining the corresponding points of the image feature points in the 3D average human face model, performing a fitting operation on the basis of the information of the image feature points and the corresponding relation between the image feature points and the corresponding points in the 3D average human face model, and acquiring 3D human face reconstruction deformation model coefficients; correcting the 3D average human face model according to the deformation model coefficients to acquire a reconstructed preliminary 3D human face; and acquiring the texture coordinate of each point of the preliminary 3D human face to realize the 3D human face reconstruction. The embodiments of the present application also provide a 3D human face reconstruction apparatus. The embodiments of the present application can perform 3D human face reconstruction on any image.
