| Research Abstract |
This study proposes a method for detecting the position of blind person indoors using visible light communication and a high-speed camera equipped w/a fish-eye lens. An experimental apparatus consisting of fluorescent or LED(Light Emitting Diode) lights and a handheld optical sensor. The light can transmit a unique positional signal(Signature) using an additional controller for real time positioning for an optical context map. In the experiment using a prototype circuit board with camera and FPGA(Field Programmable Gate Array), we confirmed that maximum signature decoding rate was 1 kHz.
