To simplify the visual positioning platform calibration process of automation equipment, reduce the reliance on the standard block and realize the automatic calibration, this paper presents a visual self-calibration method based on template matching, relying on the platform motion captured images to recognize the target of any scene, and then builds a mathematical model to calcu-late the calibration results;Gives the principle, process, and fault tolerance method of self-calibration, suitable for multi-objective sit-uation. The whole process calculates the calibration results from coarse to fine points with 3 laps automatically, making calibration more practical and generalization. The proposed method is successfully applied to the LED die bonder. The results show that posi-tioning accuracy can reach 13.947 um based on the method, which can meet the calibration requirements of the relevant equipment.
