Vehicle recognition method using reflectors for automotive infrared laser radar

In recent years, there are many collision accidents between vehicles due to human errors. As one of measures against the collision accidents, a radar system mounted on a vehicle has been attracting attention. By the radar mounted on a vehicle, it is possible to recognize the situation around the vehicle. The ranging with automotive infrared radar is very accurate, and able to understand the object existence in the observation around the vehicle. However, in order to grasp the situation around the vehicle, it is necessary to be aware of the attribute of the detected object. The information obtained by the automotive radar vehicle is only the direction and the distance of the object. Thus, the determination of the attribute of the detected object is very difficult. In this paper, we propose a vehicle recognition method by using reflectors. Through experiments, we show that the proposed method is effective for vehicle recognition.
