Utilization of Spatio-Temporal Image for LED Array Acquisition in Road to Vehicle Visible Light Communication

In this paper, the authors focus on visible light communication systems for road-to-vehicle communications (R2V-VLC). The authors use a light-emitting diode (LED) array as a transmitter and a high-speed camera as a receiver. To implement roadside to vehicle-visible light communication (R2V-VLC), it is necessary for the receiver to search the target LED array from the captured images (LED array acquisition) before data demodulation. The authors propose a new approach for LED array acquisition. The authors present a new perspective on the channel whereby the channel can be represented by a three-dimensional spatio-temporal image. The authors show LED array in the spatio-temporal image has high time-gradient value and low space- gradient value. Using such characteristic gradient values, the authors propose a new LED array acquisition method. As the results of the experiment in driving situation, the authors can achieve acquisition miss rate = 0%.
