This technique proposed a auxiliary position error process with vision system. This process includes the operating instrument. The process includes the operating instrument, and the calibrating step of 3D cloud points module.First, determine the work area and generate the module to the first point clouds. Then follow the calibration steps and compare the test module with visualization. Finally, the error and the centroid will compute with the two point clouds by the iterative closet method.
