| Summary |
In this paper, we focus attention on the visible light communication systems using an LED array as a transmitter and a high-speed camera as a receiver for road-to-vehicle communications in intelligent transport systems. Previously, we have proposed the hierarchical coding scheme which enables reception of high-priority data even if the receiver is far from the transmitter and have confirmed the effectiveness of the hierarchical coding scheme from results of primitive implementation experiments. However, there are many important works to develop the real-time communication system for an actual driving situation. In this paper, we discuss a robust receiver design in an actual driving situation. We introduce a series of image processing operations and demonstrate their effectiveness by field trials. As the results of the field trials, we have achieved 16kbps transmission and error-free communication up to communication distance of 70m using 16x16 LED array (transmitter) and high-speed camera (receiver) with the frame rate of 1000. |
