Description

technical field

[0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, electronic equipment and storage medium for three-dimensional reconstruction of a human face. Background technique

[0002] In recent years, with the development of augmented reality (Augmented Reality, AR) technology, there is a demand in AR applications to obtain face images from cameras to realize three-dimensional reconstruction of faces. Wherein, the three-dimensional face reconstruction refers to generating a three-dimensional face model based on a two-dimensional image including a face, that is, a face image.

[0003] In the related technologies, the 3D morphable model (3D Morphable Model, 3DMM) is generally used to realize the 3D reconstruction of the face. Specifically, a large number of 3D prototype faces are obtained first, and a complex preprocessing process is performed on these 3D prototype faces, and then Statistical modeling of th...
