内容記述 | 本稿では高度道路交通システム(ITS)のための路車間可視光通信に着目する.この通信では送信機としてLEDアレイを,受信機として高速度カメラを用いる.路車間可視光通信を行うには,高速度カメラで撮影された画像中のどこに送信LEDアレイがあるのかをデータ復号前に捕捉する必要がある.正確なLEDアレイの捕捉を目指し,本稿では時空間画像を用いてLEDアレイの解析を行う.その結果時空間画像においてLEDアレイは高い時間方向勾配値と低い空間方向勾配値を持つことを示す.その後,これらの特徴的な勾配値を用いたLEDアレイ捕捉手法を提案する. In this paper, we focus attention on road-to-vehicle visible light communication(R2V-VLC) in intelligent transport systems. This system uses an LED array as a transmitter and a high-speed camera as a receiver. To implement R2V-VLC, it is necessary to acquire the target LED array from the captured images at receiver before data demodulation. To achieve accurate acquisition, we analyze LED array by use of Spatio-temporal image. As the result of the analysis, we show the LED array in the spatio-temporal image has high time-gradient value and low space-gradient value. After that we propose a new LED array acquisition method using such characteristic gradient values. | |||||
