1. A method for generating an expression model performed by a computer device, the method comprising:
obtaining a reference expression model corresponding to a first expression of a target object;
performing model transformation on a sample expression model set of a sample object by using the reference expression model of the target object as a reference, to obtain a target expression model set of an approximate object of the target object, the target expression model set comprising n expression models of the approximate object; and
performing mesh deformation on the reference expression model of the target object according to a mesh deformation difference between a first expression model corresponding to the first expression and a second expression model corresponding to a second expression in the target expression model set, to generate a deformed expression model corresponding to the second expression of the target object.
