| Summary |
In this paper, we focus on the visible light communication (VLC) for ITS application using LED light source as a transmitter and high-speed image sensor as a receiver (image sensor communication: ISC). In ISC, the data reception is performed by extracting luminance corresponding to the transmitter from captured images. However, since either transmitter, receiver, or both moves with vehicles, the transmitter position is moved between frames and it confuses receiver to select the correct pixels. Hence, we treat such movement referred to as optical flow as channel fluctuation. In our previous work, we proposed a model that expressed motion of transmitter in captured images by using a single pinhole camera. In this paper, we derive channel fluctuation characteristic by numerical analysis based on the proposed model and evaluate its validity by comparing with channel fluctuation characteristic obtained by actual measurement. |
