Method and device for generating virtual object facial animation, storage medium, and terminal

Abstract

A virtual object facial animation generation method and device, a storage medium, and a terminal, the method comprising: receiving an image frame to be processed, the image frame including an actor's facial image; reconstructing based on a preset three-dimensional facial model and the facial image Obtaining the actor's three-dimensional face, the preset three-dimensional facial model is used to describe the facial expression changes of the actor; extracting a plurality of three-dimensional feature points from the three-dimensional face; based on the relationship between the three-dimensional feature points and animation data The mapping relationship is to determine the animation data corresponding to the plurality of three-dimensional feature points; generate the facial expression of the corresponding virtual object based on the animation data, and the generated facial expression of the virtual object is the same as that of the actor in the facial image The expressions you make are consistent. The scheme of the present invention can provide an efficient and high-precision virtual object facial animation generation scheme, and the generated virtual object's face has a high degree of similarity to the actor's real facial expression.

Description

technical field [0001] The invention relates to the technical field of virtual digital objects, in particular to a method and device for generating facial animation of a virtual object, a storage medium and a terminal. Background technique [0002] The facial capture (referred to as face capture) animation technology mainly includes two parts: offline facial animation production and real-time driving of the facial expressions of virtual characters. [0003] In the traditional animation production process, in order to produce high-quality facial animation, the animator not only needs high production ability, but also is very time-consuming. In addition, in the traditional animation production process, it is impossible to drive the facial expressions of virtual characters in real time. [0004] The face performance animation technology (that is, the aforementioned face capture animation technology) that has appeared in recent years accelerates the production of offline animat...

AI Technical Summary

Problems solved by technology

[0005] However, the existing face-capture animation technology still has many problems such as time-consuming production, high labor costs, and low-quality faces of generated virtual objects.
