Abstract
Techniques for reconstructing three-dimensional face images are described herein. The disclosed techniques include acquiring a real two-dimensional face key point and a predicted two-dimensional face key point; solving a first loss function consisting of the real two-dimensional face key point, the predicted two-dimensional face key point and a preset additional regular constraint term to iteratively optimize an expression coefficient, where the additional regular constraint term is used for constraining the expression coefficient such that the expression coefficient represents a real state of a face; and reconstructing a three-dimensional face image based on the expression coefficient.
