1. A computer-implemented method performed by a computer device, the method comprising:
obtaining n sets of image pairs of a target object in n types of head postures, the n sets of image pairs comprising color feature images and depth images in the n types of head postures, an ith head posture being corresponding to an ith set of image pair, n being a positive integer, 0<i≤n;
constructing a 3D human face model of the target object according to the n sets of image pairs;
generating an expression base corresponding to the target object based on the 3D human face model;
extracting a texture map of the target object from the color feature images of the n sets of image pairs; and
generating a 3D human face model with texture of the target object according to the expression base and the texture map.
