Claim 5:
6. The apparatus of claim 5, wherein the face reconstruction unit comprises:
a rotation sub-unit configured to rotate 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;
an image generation sub-unit configured to generate a first facial image of each chess player based on the first face model of the chess player;
a coordinate determination sub-unit configured to determine 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;
a coordinate acquisition unit configured to obtain 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
a face generation sub-unit configured to reconstruct 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.
