We have been proposing visible light road-to-vehicle communication at intersection, using LED traffic light as the transmitter and on-vehicle high-speed camera as the receiver. Visible light communication is a wireless communication method using luminance, transmitting data by emitting light. Thus when we use image sensor as the receiver, detection of the transmitter is required to enable the communication. In this paper, we propose transmitter detection algorithm supposed that the sequence is captured at 1000fps. We also made experiments to verify our algorithm, using the sequence captured by a high-speed camera fixed on a vehicle which is running at 30km/h.
