Three-dimensional face model generation method and device, computer device and storage medium

Abstract

The invention discloses a three-dimensional face model generation method and device, a computer device and a storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining a two-dimensional face image; calling a face model generation model, the face model generation model being used for extracting global features and local features of the two-dimensional face image, obtaining three-dimensional face model parameters based on the global features and the local features, and generating a three-dimensional face model corresponding to the two-dimensionalface image based on the three-dimensional face model parameters; and inputting the two-dimensional face image into the face model generation model, and outputting a three-dimensional face model corresponding to the two-dimensional face image. According to the method, a three-dimensional face model is obtained by integrating global features and local features in the generation process of a face model generation model. Compared with a three-dimensional face model obtained only according to local characteristics, the obtained three-dimensional face model has the advantages that face details arereflected more obviously, face detail processing is finer, the restoration degree is high, and therefore the three-dimensional face model is more real.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for generating a three-dimensional human face model. Background technique [0002] With the development of computer technology, the technology of generating 3D face models based on images has been applied in many fields. For example, this technology has been widely used in fields such as face recognition, public security, medical treatment, games or film and television entertainment. [0003] At present, the 3D face model generation method usually extracts the global features of the 2D face image, and calculates the 3D face model parameters according to the global features, so that the 3D face model can be calculated according to the 3D face model parameters. [0004] The above 3D face model generation method only extracts the global features of the 2D face image, and the 3D face model calculated based on the globa...
