Visible light communication based vehicle positioning using a rolling shutter CMOS sensor

초록

This paper proposes a technique for determining the position of a moving vehicle using LED street lights and a CMOS sensor camera. In this system, LED street lights transmit their identification codes to a camera attached on the vehicle. Then, a single view geometry technique is used to determine the position of the camera. Normally, the high speed of the vehicle combined with the rolling shutter mechanism of the CMOS sensor lead to image artifacts, which greatly degrade the positioning accuracy. In this paper, a special mechanism is applied to compensate for the image artifacts to achieve a high positioning accuracy even though the vehicle is moving at a high speed. © 2016 IEEE.
