Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we focus on the image sensor based vehicle-to-infrastructure visible light communication (V2I-VLC) for Intelligent Transport System (ITS).
In this communication system, individual detection and tracking of
multiple transmitters is critical. In other words, it is identification of the LED headlight between the frames.
However, when occlusion occurs due to vehicle's movement, it becomes
I have the problem that it comes to have difficulty in identification of
LED headlight then.
Therefore, in this paper, we propose LED identification method that
predict the position of the LED headlight on the image sensor when
occlusion occurs.
I install a high-speed camera in the roadside and test it and evaluate
proposal technique.
As a result, false negative rate is 1.38%,false positive rate is
I confirmed that I could perform LED identification even if occlusion occurred.
