Impact of Number of LEDs on An Optical Camera Communication Based Indoor Positioning System

摘要

Optical camera communications (OCCs) technology utilizes lighting infrastructure for both illumination and data transmission and a camera for the data receiver. Recently, implementing OCC for indoor positioning has drawn a lot of attention.We consider an indoor environment with some light emitting diodes (LEDs) lighting access points for positioning and estimate the location of the camera using the angle viewed from the camera’s lens. In this work, impact of number of LEDs on the preciseness of the positioning is investigated theoretically and validated experimentally. We show that increasing the number of LEDs has a significant effect on the performance of the proposed indoor positioning system (IPS).
