[0054] 1. First, place the plate to be machined on the workbench, control the camera mechanism to take a picture of the plate to be machined, obtain a shooting photo, and the shooting photo contains coordinate information; 2. Then, the shooting photo is processed to obtain the shooting contour of the plate to be machined; 3. Then, according to the first setting rule, mark at least three calibration points on the shooting contour, specifically, obtain the shooting contour, and mark at least three calibration points on the shooting contour for subsequent processes; for example Figure 2As shown, 5 calibration points are selected in the rectangular profile diagram, the more calibration points, the better the calibration effect, but the calibration time will increase accordingly, and the actual use needs to be selected; generally, the plate to be processed is a relatively regular polygon, and there is also a curved graph; the above first setting rule can be: at least three calibration points are not on the same straight line; if the calibration points are all on a straight line, there may be a case that only one edge is calibrated, at which time the calibration ratio cannot be obtained; 4, the probe reaches the calibration point according to the second setting rule to obtain the real coordinate point; according to the calibration point coordinate, the probe is moved to different calibration points, for example, the second setting rule can be in the form of clockwise surrounding the shooting profile diagram and reaching different calibration points in turn; at this time, the real coordinate points at different calibration points can be obtained; specifically, the probe can be controlled to quickly reach the calibration point range to hit the plate to be processed; then the probe is controlled to slowly return to the calibration point, at which time the coordinate point of the probe is the real coordinate point of the plate to be processed at the calibration point; 5, finally, according to the calibration rule, the calibration point and the real coordinate point, the shooting photo is calibrated to obtain a calibration photo, and the plate to be processed can be processed according to the coordinate of the plate to be processed on the calibration photo; according to the difference between the calibration point and the real coordinate point, the ratio of the shooting photo that needs to be calibrated can be calculated and obtained, and the shooting photo is calibrated according to the ratio to obtain a calibration photo. At this time, the coordinates of the plate to be processed on the calibration photo can be considered as the real coordinates of the plate to be processed; the plate to be processed can be processed according to the coordinates of the plate to be processed on the calibration photo; the above calibration rule can be specifically: calculating the error ratio between the shooting profile diagram and the actual profile diagram of the plate to be processed according to the calibration point and the real coordinate point, and calibrating the shooting photo according to the error ratio to obtain a calibration photo.
