| 要約 |
We propose a visible light road-to-vehicle communication system at intersection as one of ITS technique. In this system, the
communication between vehicle and an LED array is approached using LED array as a transmitter, and on-vehicle high-speed camera as a
receiver. The LEDs in the transmitter are emitted in 500Hz and those emitting LEDs are captured by a high-speed camera for making
communication. Here, the luminance value of LEDs in the transmitter should be captured in consecutive frames to achieve effective
communication. For this purpose, first the transmitter should be identified, then it should be tracked in consecutive frames while the vehicle
is moving, by processing the images from the high-speed camera. In this paper, we mainly introduce an algorithm to track the transmitter
using optical flow and edge information. |
