Method and system for compensating chess piece falling precision of chess playing robot based on visual identification

Abstract

The invention discloses a chess playing robot chess piece falling precision compensation method and system based on visual identification. The system comprises a robot control module, a visual identification module, a chess piece sending system and a chessboard. The method specifically comprises the following steps: step 1) positioning the position of a chessboard in a pixel space through the visual identification module by using a polygon fitting method; (2) the n chess pieces are placed at preset positions of the n chess pieces on the chessboard through the sending subsystem; (3) the positions of the n chess pieces in the pixel space are recognized through a visual recognition module; and (4) the positions of the n chess pieces in the pixel space use the mapping relation of similar triangles to obtain chess piece position errors, then an error compensation value function is obtained in combination with preset position coordinates of the n chess pieces, finally compensation is achieved according to the chess piece falling precision compensation principle, and finally the chess piece falling precision of the mechanical arm is improved.
