Method and apparatus of constructing chess playing model

An apparatus of constructing a chess playing model, comprising:

• an information acquisition unit configured to acquire a video image of each chess player at a time point and a distribution relationship information between a chess piece and a chessboard in a chess game at the time point;
• an information determination unit configured to determine a two-dimensional position information for a first expression characterization point in the video image and a marking information for a facial structure characterization point in the first expression characterization point, wherein the first expression characterization point is marked in a facial region of the chess player in the video image;
• a rotation determination unit configured to determine a rotation information for each chess player in a specified direction based on a two-dimensional position information for the facial structure characterization point and the marking information for the facial structure characterization point of the chess player;
• a face reconstruction unit configured to reconstruct a three-dimensional reference face model of each chess player according to the two-dimensional position information for the first expression characterization point and the rotation information for the chess player, so as to generate a three-dimensional target face model of the chess player;
• a chess player reconstruction unit configured to reconstruct a three-dimensional target chess player model of the chess player based on the target face model of the chess player and a three-dimensional reference body posture model of the chess player;
• a chess game reconstruction unit configured to reconstruct a three-dimensional target chess game model according to the distribution relationship information and a three-dimensional reference chess set model;
• and
• a chess playing reconstruction unit configured to reconstruct a three-dimensional target chess playing model according to the target chess player model, the target chess game model and a reference position relationship simulating a real chess playing scene.
