Abstract�� The information of surrounding was gotten by the way of vision technology in intelligent vehicle system. It is very important to detcect other vehicles in front of the ego vehicle on road. The method of vehicle detection was proposed. The method of Ostu threshold was used to realize image binarization. Searching line may be the line of the shadow of vehicle-s bottom as the AOI-s (Area of Interest) bottom boundary. The expanding of the AOI was realized.The symmetry measurement and symmetry measurement of normalized entropy were used to determine whether the region is vehicle or not. The upper boundary was determined by checking the gray mutant line in the gray image. This method was tested, and got good results. The method paves the way for the latter distance measurement between vehicles.
Keywords�� computer vision   vehicular shadow information   vehicle detection
