Integration of photogrammetry and optical camera communication technologies for vehicle positioning

We propose an algorithm for vehicle positioning approach comparing the relative distance between street lights and forwarding vehicle. Rolling shutter CMOS (complementary metal-oxide-semiconductor) camera on the host vehicle detects the LED-ID (light-emitting diode-ID) from both the street LED lights and rear LED lights of the forwarding vehicles. The distance between vehicles can be measured by comparing the change of pixels on the image sensor of the camera. At the end of this paper, we provide simulation result to show the performance of our proposed scheme.
