A fast vehicle detection method based on symmetry of vehicle edge and the level of the shadow is proposed.Firstly,the detected image through the use the method which makes the detected image minus the background image,and remove large number of disturbances in the lane maximum in the background image to highlight the vehicle images;Secondly,the edge detecting of the image with Sobel,vertical and horizontal edges detection algorithms separately is finished.And then zoom and segment image to three of the same size image like vision,medium shot,close range image.Finally,the symmetry of the vehicle is used to detect the three separate images and make sure all vehicles at the image's horizontal position in the image,and the level of the shadow and the level edge of the bottom of the car are utilized to determine the vertical position of the car.Experimental results show that this method is simple,rapid and can detect out all the different locations of vehicles and different sizes of the vehicle in the image accurately.
