¿µ¹®³»¿ë (English Abstract) |
A fast circle-detection method is proposed in this paper. This method uses information of constraints under industrial vision environment and geometric characteristics of circles Its correctness and performance are evaluated through experiments for graphic images and real images. The method can also detect broken circle very fast and correctly when more than a half of its boundary remains intact. It can be applied well to industrial vision systems, because the light condition and the motion constraint can be well defined in industrial vision environment However, it does not work well for noisy images and can not dctect occluded circles.
