The Research Of The Vision Algorithm And Intelligent Control Software For Chess Robot

The technology of robot integrates artificial intelligence, pattern recognition, mechanics, bionics and so on. With the development of robot, its functions are more and more rich. The study of entertaining robot already becomes a very important direction. Chess robot is one of the entertaining robots. This paper based on image processing, artificial intelligence and computer technology, designs and realizes the vision and knowledgeware of chess robot.The robot vision is an image processing and analysis process. This paper using the common method of image fore processing currently, transforms the colorized image to gray and makes it only tow values by a critical point threshold. The method of thinning is applied to this worked image in order to remove unnecessary information and reduce the image data that could be computed later.Then by the methods that detecting the crossings, modifying the coordinates, making contour, searching for the largest area and so on, the worked image is analysed and the chessman's coordinates are gained. The chessman's identities are distinguished using logistic method.In the design of creating chessman's moves, the format of chessboard data, the rules of move, the algorithm of creating move , the evaluation algorithm and the search algorithm are designed based on the structure of chess game. The searches of negative max algorithm and Alpha-Beta algorithm are introduced detailedly and realized.Designing the structure of knowledgeware for robot. It includes the main interface, the functions of parameter setting, vidicon administration and adding and administering searches. The vision and the part of creating chessman's moves are also integrated into this knowledgeware organically. Designing the interface keywords and agreements for developping the search that makes the knowledgeware have opening quality. Finally, this paper does experiments about the part of vision, creating chessman's moves and the whole systerm, validates validity and reliability of the algorithm.
