Background

With the rise of artificial intelligence, the man-machine chess playing as a more intuitive artificial intelligence computing form is gradually known by most people. The identification end, the operation end and the display/execution end can be used as the eye, brain and hand of artificial intelligence to build the simplest human-computer chess system. The three respectively undertake corresponding functions, and the final result is influenced no matter which link goes wrong. And the recognition end as an integral input part, which has the most profound effect.

In each chess category, the identification of the chess has higher requirements compared with the chess categories that only black and white chess pieces need to be identified to play games, such as gobang and go. Therefore, it is necessary to determine the kind of the chessman and determine the formation of the chessman.

However, most of the current chess piece recognition technologies are visual recognition, and the features and positions of the chess pieces are obtained by means of image processing. For Chinese chess identification, the engraved characters of the Chinese chess pieces, the engraved colors of the Chinese chess pieces and the center positions of the Chinese chess pieces need to be identified. This requires a high resolution camera, a uniform and stable lighting environment, and sophisticated image processing algorithms. The identification mode has the defects of high cost, slow processing and incapability of meeting the complicated illumination environment, and all the defects cause obstruction to the human-computer playing of the chess. Therefore, it is necessary to provide a further solution to the above problems.

Detailed Description

The present invention is described in detail below with reference to various embodiments, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should be able to make modifications and substitutions on the functions, methods, or structures of these embodiments without departing from the scope of the present invention.

As shown in fig. 1 and 2, the present invention provides an intelligent chessboard, which comprises: a board body 10, a magnetic sensing module 20, a main control module 30 and an identification module 40. In an integrated manner, the magnetic sensing module 20, the main control module 30 and the identification module 40 are embedded in the board body 10. So arranged, while integrating more functions, it does not affect the basic functions of the board body 10 itself.

The surface of the board body 10 is formed with a Chinese chess board lattice, and the chess board lattice is provided with point positions of each chess piece.

The magnetic sensing means 20 is used for identifying the playing pieces on the board body 10 and comprises a number of magnetic sensors. Magnetic sensors are correspondingly arranged below any point position of the chessmen. Correspondingly, a magnetic signal emitting device is integrated in the chess pieces matched with the intelligent chess board, and the magnetic sensors below the point positions of the chess pieces can collect magnetic signals emitted by the corresponding chess pieces. Therefore, the positions and the number of the chessmen can be identified by the magnetic sensing module 20, so that the influence of a complex illumination environment on chessman identification is avoided, and the requirement of chessman identification under most conditions can be met.

The identification module 40 is used to identify the pawn that is eaten. Specifically, the identification module 40 is at least one group, which can identify the number of the chessman matched with the intelligent chessboard. In one embodiment, the identification modules 40 are in two groups, two groups of identification modules 40 being arranged diagonally on the board body 10. Therefore, the two parties can conveniently identify and record the eaten chess pieces by the own identification module 40.

When the chessmen are identified, the user can place the eaten chessmen in the identification area of the identification module 40, and then the identification module 40 identifies the serial numbers of the chessmen. In one embodiment, identification module 40 is an RFID identification module 40. Correspondingly, a chip is integrated in the chess pieces matched with the intelligent chess board, and the identification module 40 can read the serial number data stored in the chip.

The main control module 30 performs data transmission with the magnetic sensing module 20 and the recognition module 40, respectively, so as to receive and process the piece recognition data fed back by the magnetic sensing module 20, so as to obtain the magnetic field information of each grid point, i.e. the fall information. Meanwhile, the eaten piece data fed back by the recognition module 40 is also received and processed. In one embodiment, the master control module 30 includes a single-chip microcomputer.

The intelligent chessboard further comprises a power module 50, wherein the power module 50 supplies power to the magnetic sensing module 20, the main control module 30 and the identification module 40. Correspondingly, the power supply module 50 also has terminals 51 integrated in the bottom of the board body 10 for receiving external current inputs. So, power module 50 carries out the steady voltage with the power that the outside provided through the terminal and distributes for each module after for the whole power supply of intelligence chess board, supplies its steady operation. In addition, the main control module 30 has a terminal for communicating with the outside.

Based on the same technical concept, the invention also provides a chess piece identification method based on the intelligent chess board, which comprises the following steps:

identifying the initial state of the chessmen through a magnetic sensing module;

judging whether the opening condition is met or not according to the identification result, and establishing a chessboard array;

if the game starting condition is met, detecting the state of the chess pieces on the chessboard body in real time, and recording the movement data of the chess pieces;

and when the recognition module feeds back the draft data, updating the established chessboard array.

Wherein, the state of the chessman is identified by the following steps: the positions of the chessmen and the number of the chessmen on the chessboard body are identified.

Specifically, the invention considers the difference of chess playing modes compared with gobang, weiqi and the like, and judges whether the chess playing conditions are met or not through the positions and the number of the chess pieces on the chessboard by the magnetic sensing module when the chess is played based on the rule that the chess pieces are placed according to fixed positions, and establishes a chessboard array for storing the positions of different chess pieces on the chessboard. When the game is matched, the magnetic sensing module monitors the state of the chessboard in real time and records the movement of the chessmen in a related way. When a game event occurs, the game is placed on the recognition module to recognize the game and the chessboard array is updated correspondingly, so that the whole game is supported.

In conclusion, the intelligent chessboard avoids the influence of a complex illumination environment on the chessman identification, and can meet the requirement of chessman identification under most conditions. In addition, the intelligent chessboard of the invention has the advantages of low cost, high recognition rate and high recognition success rate, and can perfectly support man-machine chess playing of the Chinese chess.
