A non-contact man-machine game control method and system based on machine vision

Abstract

The invention discloses a machine vision based non-contact man-machine chess playing control method and system. The method provides a Chinese chess piece motion detection method including human hand skin color detection, background modeling, background subtraction and chess piece position detection, can achieve non-contact detection of a checkerboard, and can acquire the motion trails of chess pieces. The system includes common Chinese chess, a uArm four-freedom degree mechanical arm, a sucker, a camera, a light source, and a control unit. The system is simple in structure, is easy to operate,can automatically trigger a Chinese chess robot to execute a corresponding playing act without contacting any key after a man does an act during a man-machine chess playing process, can achieve non-contact man-machine chess playing, and has good stability in a relative complex environment.

Description

technical field [0001] The invention belongs to the field of machine vision detection, in particular to a non-contact man-machine game control method and system based on machine vision. Background technique [0002] With the development of robot technology, the functions of robots are becoming more and more abundant. At present, the chess robot, one of the entertainment robots, has become an important direction of robot research. Traditional chess robots usually use the chess board as a sensor to identify chess pieces in terms of chess game recognition and positioning. This method has a large workload and complex scene layout, which makes it difficult for chess robots to be popularized. At the same time, the method used for chess robot man-machine games is to add An external sensor, or an external button is added as a trigger device. [0003] After reviewing related literature, the paper "Manufacturing of Intelligent Error Chessboard Human-Machine Pair Chess Robot" (Huang ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problem of chess piece reading existing in human-computer games of chess robots, the present invention provides a non-contact chess robot control method based on machine vision, which realizes non-contact human-computer game functions, that is, without human intervention. The machine-to-game process control realizes the fully automatic control process from detection and identification of chess move information to the movement of chess pieces by the mechanical arm
