This paper mainly provides a visual system as an identification method for cylindrical workpiece without placing rules.The main work including light source selection method,the camera calibration and choosing;The second part puts forward the measures of Histogram equalization and Median filtering,then shows the improving Hough transform to detect straight line and the regional growth method.According to the characteristics of the being matched,object an interpolating method for calculating the midpoint of line through the combination of point matching and line segment matching is proposed.Checking the novelty of this system,it's sure that this paper has important theoretical significance and potential application value.
