| Abstract: | Based on the theory of digital image processing and combining with the image characteristics, the practical methods and results of image processing were presented. Meanwhile,two different approaches, ellipses curve fitting and grey mass center,which are used to detect the image coordinates of the center of an elliptical light spot,were proposed. The result shows that the application of grey mass center in the light pen vision measuring system was feasible. |
