Claim 1:
2. The method of claim 1, wherein the reconstructing a three-dimensional reference face model of the chess player according to the two-dimensional position information for the first expression characterization point of the chess player and the rotation information for the chess player, so as to generate a three-dimensional target face model of the chess player comprises:
rotating a reference face model of each chess player based on the rotation information for the chess player, so as to obtain a first face model of the chess player;
generating a first facial image of each chess player based on the first face model of the chess player;
determining a two-dimensional position information for a second expression characterization point in the first facial image, wherein the second expression characterization point is marked in the facial region of the chess player in the first facial image, and the first expression characterization point of the chess player and the second expression characterization point of the chess player have a corresponding relationship in the face position of the chess player;
obtaining a three-dimensional target position information for each chess player by using the two-dimensional position information for the first expression characterization point and the two-dimensional position information for the second expression characterization point according to the corresponding relationship between the first expression characterization point and the second expression characterization point of the chess player; and
reconstructing the first face model of the chess player based on the three-dimensional target position information for the chess player, so as to generate the target face model.
