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.
