Abstract:

A sorting system based on industrial robot of machine vision is proposed to solve the low efficiency and poor quality control of the traditional manual sorting operation.The system combines the image segmentation with image matching to overcome the disadvantages that traditional visual algorithm is affected by light and noise.The experiment system collects chess pieces and scene image and carries on the image processing,extracts the coordinates and classification of the black and white chess pieces,implements the coordinate conversion,maintains the movement trail of the sorting chess pieces,and controls the movement of the robot to realize the sorting action.The experimental results show that the hardware and software design of the control system is correct,and the success rate of the sorting is high with easy implementation.
