An expression animation data processing method is provided for a computer device. The method includes determining a location of a human face in an image and obtaining an avatar model; obtaining current expression data according to the location of the human face in the image and a three-dimensional face model; and obtaining expression change data from the current expression data. The method also includes determining a target split-expression-area that matches the expression change data, the target split-expression-area being selected from split-expression-areas corresponding to the avatar model; and obtaining target basic-avatar-data that matches the target split-expression-area. The method also includes combining the target basic-avatar-data according to the expression change data to generate to-be-loaded expression data; and loading the to-be-loaded expression data into the target split-expression-area to update an expression of an animated avatar corresponding to the avatar model.
