Three-dimensional facial expression base establishing method and device, storage medium and electronic equipment

Abstract

The invention relates to the technical field of image processing, and particularly relates to a three-dimensional facial expression base establishing method and device, a computer readable storage medium and electronic equipment. The method comprises the steps that target key points of a target face image in input data are extracted, a camera projection matrix is determined according to the targetkey points and initial key points, corresponding to the target key points, in an average face model, and the average face model is a reference three-dimensional face model obtained according to facemodel data set processing; the camera projection matrix is used to calculate a target three-dimensional face model corresponding to the target face image according to the target key point, the averageface model reference three-dimensional face model and the initial key point; and a target three-dimensional facial expression base corresponding to the target human face image is generated by using the target three-dimensional human face model. According to the technical scheme, the problems that in the prior art, an obtained expression base model is poor in effect and large in calculated amountcan be solved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method and device for establishing a three-dimensional facial expression base, a computer-readable storage medium, and electronic equipment. Background technique [0002] With the development of the Internet, the technology established based on 3D facial expressions is also widely used in animation production, game production, human-computer interaction, film and television advertisements, etc. [0003] However, the 3D face expression base building method in the prior art has a low degree of automation and inconsistent standards, and the obtained expression base model is poor in effect and requires a large amount of calculation. [0004] Therefore, it is necessary to design a new method for building a 3D facial expression base. [0005] It should be noted that the information disclosed in the above background section is only for enhancing the understandi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present disclosure is to provide a method and device for establishing a three-dimensional facial expression base, a computer-readable storage medium, and electronic equipment, so as to overcome at least to a certain extent the low degree of automation of the three-dimensional facial expression base establishment method in the prior art, Inconsistencies in the standard vertebrae, the obtained expression base model has poor effect and a large amount of calculation
