- Abstract
In forging production line, solving the problem of workpiece calibration by the traditional method is low efficiency and poor accuracy, so a visual calibration method is proposed to get the posture relationship between robot and workpiece. To obtain the intrinsic and extrinsic parameters of camera, a calibration toolbox is used to extract grid corners and calibrate the plane calibration template. A teaching workpiece's coordinates experiment is used to test the validity of the method above. The experimental result shows that the robot could finish the workpiece grasping job quickly and accurately, the average error of workpiece coordinate is within 0.3% and the accuracy of the calibration can meet the requirements of the actual production line.
