Abstract
We present a real-time indoor visible light positioning system based on optical camera communication, where the coordinate data in the on and off keying format is transmitted via light emitting diode (LED) based lights and captured using a smartphone camera. The position of camera is determined using a novel Perspective-n-Point problem algorithm, which determines the geometric perspective of the LED coordinates. The experimental results show that the proposed system offers mean position errors of 4.81 and 6.58 cm for the heights of 50 cm and 80 cm, respectively.Keywords
