Yongsik Kang, Junghoon Lee, Juyoung Lee, Jaesang Cha · 2011
In this paper, we proposed indoor position detection method using LED QR code and smart-terminal. We proposed a kind of Indoor position detection method using LED QR code and smart-terminal since many people use smart-terminal and QR codes have increased utilization. Control Server in PC offered and updated the location coordinates of LED QR board periodically. Then coordinates of LED QR are sent to the smart-terminal to indicate indoor positioning information.
