Abstract�� In a structured-light vision system, the accuracy of center position of the stripe is of great importance for that of the whole measuring system. Processing the image of stripe is an important step, especially for images with serious noises. Methods for processing images of stripe disturbed by various noise sources were discussed, as well as the method for detecting accurately the center of stripes. A special filtering mask was submitted for "surrounding" disturbance and was verified effective. For the measuring range as large as 200mm×200mm the accuracy of the whole measuring system when using the methods mentioned is 0.083?mm.
Keywords�� optical image processing   filtering algorithm   nondestructive laser analysis   structured-light
