| Abstract(in English) | This paper presents a vehicle detection method which can separate overlap vehicles. The proposed method detects vehicles by finding moving planes perpendicular to a road plane and an optical axis of a camera. At first, two horizontal line segments adjacent vertically are detected in the present frame. Then, corresponding positions to them are searched in the previous frame by a correlation matching. If the motions of two horizontal line segments satisfy the constraint of the vertical plane, it is judged that areas between these segments are parts of vertical surfaces of the vehicles. Vehicles' areas are obtained after these detected areas are merged by examining whether horizontal line segments inside these areas satisfy the motion constraint of the vertical plane. The proposed method can separate overlap vehicles because the back surface of each vehicle is detected as the different vertical planes respectively. Experimental results for real road scenes under a traffic jam show the effectiveness of the proposed method. |
