Self-calibration processing equipment is studied through measuring the precise size of the workpiece produced in the factory assembly line based on the machine vision measurement technology. Hough circle detection algorithm and subpixel edge algorithm are adopted. After several experiments, the measuring accuracy of the device can reach 0.05mm, which meets the design requirements of measurement accuracy. The self-calibration parameters are sent to the processing equipment through the transmission layer to reduce the rejection rate and improve the enterprise benefits.
