Recognizing Chessboard and Positioning Checkboard in Chinese Chess Game System

With the widely used of augmented reality, we designed a remote chess game system based on augmented reality. It has the potential significance. The system can make two people both living in different places to play chess as they are playing face to face and can communicate with each other. In this paper, we make an introduction to the recognition and the positioning of the check board in detail. In the positioning of the check board module, a method based on the linear distance parameter of automatic threshold segmentation is presented to detect the redundant lines to eliminate. Eventually, the 9 * 10 mode was determined to be the best. We show in the experiment that this method is very effective and can play a reference to similar problems, such as Gobang, the game of go and other board games.
