Abstract: The shadow detection technology is the key technology in the intelligent traffic system. Two main traditional approaches for shadow detection are introduced, which are the one based on the color characteristic of shadow and the other one based on the three dimensional modeling. Plus, another method is one that brings the above two methods together. The experiment results show that the new one can improve the efficiency of the shadow detection greatly.

Key words: shadow detection, HSV color space, three dimensions modeling, coarse model
