Abstract

The present disclosure relates to a method, a device, a terminal and a storage medium for generating a three-dimensional expression model, and belongs to the technical field of face recognition. The method includes: determining the feature points of the face image according to the face image; determining a plurality of expression parameter values ​​according to the feature points of the face image and an expression parameter algorithm, and the expression parameter values ​​are used to represent a person The expression of a part of the face; according to each expression parameter value, in a plurality of three-dimensional models corresponding to each expression parameter, determine the three-dimensional model corresponding to each expression parameter value, and a three-dimensional model is used to represent the A three-dimensional display effect of a part; according to the three-dimensional model corresponding to each expression parameter value, a three-dimensional expression model is generated. By adopting the present disclosure, the efficiency of generating a three-dimensional expression model can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of face recognition, and in particular to a method, device, terminal and storage medium for generating a three-dimensional expression model. Background technique [0002] With the development of Internet technology, users can share their lives through pictures or videos. Sometimes the user does not want to show his real face, at this time, the user can choose to use virtual expressions to cover his real face. The virtual expression is a three-dimensional model of expression that can change correspondingly with the user's real expression. [0003] In related technologies, the step of generating a three-dimensional expression model according to the user's real expression may be: first determine the coordinate information of a plurality of feature points of the user's face image, obtain the initial three-dimensional expression model corresponding to the target virtual expression selected by the user, ...
