Abstract

The embodiment of the invention discloses a method and device for generating a virtual animation expression. The method for generating the virtual animation expression comprises the steps of obtaininga current frame of a face video; obtaining a first weight coefficient and an emotional expression label of the facial expression grid of the current frame corresponding to each basic expression basegrid; determining a second weight coefficient of the facial expression grid of the current frame corresponding to each emotional expression grid based on the emotional expression label; respectively inputting the first weight coefficient and the second weight coefficient into a facial expression model, and determining a facial expression grid, the facial expression model representing the facial expression grid by using a normal expression grid, a linear weighting result of a predetermined number of basic expression base grids and a linear weighting result of a preset number of emotional expression grids. According to the method, the emotional expression animation in the speaking process is generated in an emotional expression label mode, the animation can be vivid and vivid, the animationeffect is improved, and manual operation is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of computer network technology, and in particular to a method and device for generating virtual animation emoticons. Background technique [0002] In order to obtain richer expressions and movements, it is necessary for the virtual animation image to incorporate some special emotional expressions when speaking. For example, speaking with a smile, speaking sadly, speaking playfully, etc. In addition, we need to synthesize facial actions with multiple emotional expressions, for example, the action "smiling contemptuously" has both "scornful" and "laughing" emotional expressions. "Surprised with anger" has the two emotional expressions of "surprised" and "angry". [0003] At present, when synthesizing images, if you want to add emotional expressions in the speaking process, the following two methods are usually used to achieve: one way is to use the synthesiz...
