Title:
FACE POSE ESTIMATION/THREE-DIMENSIONAL FACE RECONSTRUCTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/042975
Kind Code:
A1
Abstract:
Disclosed are a face pose estimation/three-dimensional face reconstruction method and apparatus, and an electronic device. The face pose estimation method comprises: acquiring a two-dimensional face image to be processed, constructing a three-dimensional face model corresponding to the two-dimensional face image, and determining a face pose of the two-dimensional face image according to a face feature point of the three-dimensional face model and a face feature point of the two-dimensional face image. By means of the processing method, pose solution is performed based on a three-dimensional face model corresponding to a two-dimensional face image, instead of performing pose solution only based on a three-dimensional average face model, such that when pose estimation is performed on large-angle and exaggerated facial expressions of a face, a high-precision pose can still be obtained. Therefore, the robustness of pose estimation can be effectively improved.
