Chess piece positioning and recognition method and system based on chessboard surface image

Abstract

The invention discloses a technical solution for chess piece positioning and recognition based on a chessboard surface image. In the technical scheme, the chessboard surface has a characteristic texture image, and the microprocessor inside the chess piece processes the obtained chessboard texture image, directly determines the coordinate position of the chess piece in the chessboard according to the image features, and then encodes the chess piece category code and the chess piece position coordinates Send to the chessboard controller through the wireless interface; the chess pieces can also send the obtained chessboard texture image and chess piece category code to the chessboard controller through the wireless interface, and the chessboard controller determines the position coordinates of the chess pieces in the chessboard according to the feature image. The technical solution proposed by the invention is not affected by external light source changes and object occlusion, and the positioning of chess pieces is accurate, providing a basis for electronic chessboards, robot games, and man-machine games.

Description

Technical field [0001] The present invention relates to the intelligent identification techniques of chess games, and in particular, to the positioning techniques of chess pieces and positioning techniques on the board. Background technique [0002] Chess games are a puzzle game that everyone likes, and chess and Go are the most popular two types of chess breeds, chess and playful chess games, interesting, and is also very beneficial to intellectual development. . With the development of computer and robotics, use electronic chessboards to record and real-time, with robots to play with people, and gradually have a large market demand. The researchers have developed and product design around the electronic board and the robot, the researchers have developed technology development and product design, and have very little product into the market. [0003] The most critical part of the electronic chessboard and the human machine is how to identify and locate the chess pieces. Current...

Problems solved by technology

Man-machine game robots in many exhibitions often use the above-mentioned technical methods to achieve, but due to the limitations of external light sources and use conditions, they can only be used for display, and there is still a long way to go before commercialization

[0004] Other relatively simple chess pieces identification and positioning methods include: RFID radio frequency technology, photoelectric sensor technology, magnetic induction technology, etc. The level of intelligence of chess pieces is very low, resulting in poor user experience and difficult to promote and use
