LED 후미등 및 초고속 카메라를 이용한 차량간 통신알고리즘

We propose an efficient vehicle-to-vehicle communication algorithm that uses LED rear lamp as a transmitter and the high-speed camera as a receiver. Visible light communication is a wireless communication method using luminance, transmitting vehicle information data by emitting light. In this paper, LED transmitter is modulated by using 8-pulse position modulation scheme and the high-speed camera is used as a receiver for demodulating the signals by using image processing techniques. We performed examination of the transmission speed according to the our communication system. The actual proof experiment of the proposed system was conducted under the laboratory conditions.
