| Summary |
Intelligent Transport Systems Visible Light Communication (ITS-VLC) is attracting significant attention as a solution to solve
various problems that vehicles have, or for the installation of new systems
in the vehicles. In ITS-VLC, the acquisition of the VLC transmitter via
light-emitting diodes (LEDs) in the onboard camera’s captured image is the
first and essential step when receiving the VLC signal. Most of the previous
research on the acquisition of the LEDs assumes that the vehicles approach
the LEDs source from the front of the vehicle. However, there are many
situations in which vehicles cross the LEDs. In this study, we considered
a case in which the vehicle’s receiver crosses the LED transmitter. We
modified the acquisition algorithm based on the spatial-temporal gradient
utilized in our model in which the transmitter and the receiver cross each
other. We found that we can acquire the transmitter by correcting the difference of the transmitter’s position in the captured image. When validating
the specific signal, we achieved 100% acquisition success rate. |
