Title:
THREE-DIMENSIONAL FACE RECONSTRUCTION METHOD, APPARATUS, AND DEVICE, MEDIUM, AND PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/032464
Kind Code:
A1
Abstract:
A three-dimensional face reconstruction method, apparatus, and device, a medium, and a product. The method comprises: acquiring face image data, and extracting a face image in the face image data; then performing key point detection on the face image to obtain a face area image of an area where face key points are located; performing bilinear modeling of a face identity and a face expression on the face area image by using a bilinear modeling layer of a three-dimensional face reconstruction network pre-trained to a convergence state, so as to obtain a parameterized three-dimensional face model; and finally, mapping the face area image into corresponding parameter coefficients in the parameterized three-dimensional face model by using a parameter mapping layer of the three-dimensional face reconstruction network.
