Automatic calibration and feedback method and system

The invention provides an automatic calibration and feedback method and system. The automatic calibration and feedback method comprises the following steps: acquiring coordinate information of a calibration block in a preset pose; then, mechanical information is obtained according to the coordinate information, and the target product is calibrated according to the mechanical information; and further collecting a calibrated target product image, obtaining a calibration result according to the target product image, and feeding back compensation information according to the calibration result. According to the method, the number of calibration steps is small, the calibration process is simple, the calibration efficiency is high, the calibration difficulty can be reduced, the calibration precision can be improved, closed-loop control is formed with adaptive feedback, real-time tracking and feedback of data are achieved, and abnormal data are adjusted in real time; the whole process is automatically completed, man
