【Abstract】 The principle of orientation technique based on image processing is discussed. A new edge detection method is proposed, and the practical implementation of edge detection, gray-level interpolation, and center calculation are introduced, which are applied in a closed loop control system. It has been verified by simulation that the aim for precise orientation can be implemented, and the maximum error is less than 002 pixel during the procedure of image processing.更多还原
