| Abstract: | A contactless detection system for the thread with digital processing technology was presented. The digital process includes filter, edge detection, binary image production and contour hunting. By analyzing the processed image, the geometrical parameter could be calculated. Sizes of a thread detected by suggested method were given,and the feasibility and correctness of the method were validated theoretically and practically. |
