The present invention includes: chessboard, operating box, image card, PC, CCD camera, support and light source. There are support set over the chessboard, one CCD camera and several light sources fixed on the support, PC connected via data cable with the CCD camera and with image card, and operatingbox beside the chessboard. The present invention is matched with Chinese chess master robot and has the effects of using common chessboard and chessmen and CCD equipment with low cost, simple and reliable principle, strong anti-jamming capacity, high sensitivity and high stability. The present invention is suitable for man-computer playing of Chinese chess, Weichi, gobang and other chesses.

Description

technical field [0001] The invention relates to a chessboard recognition system, in particular to a vision-based chessboard recognition system, which belongs to the field of visual recognition technology and electromechanical systems. Background technique [0002] There have always been many chess enthusiasts in China. The robots that can play backgammon, go, and chess have been developed. The key technology for automatic and accurate chess games with humans. At present, the chessboard system used for playing chess with robots uses various sensors on the chessboard, and requires certain modifications to the chess pieces. Through literature search, it is found that the Chinese invention patent application number: 00107744.9, the patent name is: a kind of photosensitive sensor Go board, what this patent technology adopts is that the photoresistor is arranged on the board in a dot matrix to sense the information of the chess pieces on the board. In the search, it was also fou...
