[0002] At present, chess robot vision has been applied to the process of playing chess, but in the process of setting chess at the beginning, due to the randomness of the placement of chess pieces, most chess robots place the chess pieces manually, and then the robot plays chess by itself. The efficiency of playing chess is low, and the placement of chess requires human intervention, which is not conducive to the versatility and promotion of chess robots

Embodiment Construction
[0030] The present invention will be described below in conjunction with the accompanying drawings and embodiments, but not to limit the content of the present invention.
[0031] Such as figure 1 , figure 2 Shown, the present invention a kind of automatic identification based on image processing and positioning chess robot, comprise visual system, robot carrier, transmission mechanism, wherein:
[0032] The vision system consists of a CCD camera 2 fixed on a fixed frame 1 and an annular low-angle LED light source 3. The CCD camera 2 is connected to the data acquisition card on the terminal control computer through a data transmission line; the CCD camera 2 is set on a shelf 70 cm from the ground 1; the fixed frame 1 is fixed on the left side of the transmission mechanism; the ring-shaped low-angle LED light source 3 is located 10cm below the CCD camera 2, and the positive light source provided is red light, which makes the characters or patterns on the chess surface clear, ...

The invention discloses an automatic identifying and positioning chess placing robot based on image processing. The automatic identifying and positioning chess placing robot based on image processing comprises a mechanical system and a visual system connected with the mechanical system. The visual system comprises an image collecting device and an annular low-angle LED light source connected with the image collecting device. The mechanical system comprises a transmission mechanism and a robot carrier connected with the transmission mechanism. The transmission mechanism is formed by connecting a stepping motor, baffles, photoelectric sensors, an overturning mechanism and a conveying belt, wherein the overturning mechanism and the conveying belt are connected with the stepping motor. The stepping motor drives the conveying belt to move to convey chess pieces. The overturning mechanism is provided with a suction nozzle which is used for fixing and overturning the chess pieces and then making the chess pieces fall on the conveying belt to convey the chess pieces again. The baffles are arranged on the two sides of the conveying belt. The baffles are provided with the photoelectric sensors. When the chess pieces reach the centers of the baffles through the conveying belt, the photoelectric sensors sense the chess pieces and control the chess pieces to move forwards continuously to be within the view field of the image collecting device, and the conveying belt stops running. The robot is simple in structure, high in automation degree and high in adaptability.
Description
technical field [0001] The invention relates to robot technology, in particular to an image processing-based automatic recognition and positioning chess-playing robot. Background technique [0002] At present, chess robot vision has been applied to the process of playing chess, but in the process of setting chess at the beginning, due to the randomness of the placement of chess pieces, most chess robots place the chess pieces manually, and then the robot plays chess by itself. The efficiency of playing chess is low, and human intervention is required for laying out chess, which is not conducive to the versatility and promotion of chess robots. Contents of the invention [0003] For this reason, the problem to be solved by the present invention is to provide an automatic identification and positioning robot for placing chess pieces based on image processing. The function of flipping chess pieces and repositioning and placing them. [0004] The purpose of the present inven...
