가시광 통신과 보행 항법을 이용한 증강현실 기반 실내 측위 시스템

다국어 초록 (Multilingual Abstract)

As interest in internet of things(IoT) increases, technologies to exchange a variety of information between devices have been attempted. Among them visible light communication(VLC) is a communication system using LED lamps and is suitable for implementing indoor positioning system in the indoor environment where global positioning system(GPS) signal does not reach. In this paper we combined an indoor positioning system using VLC with pedestrian dead reckoning(PDR). PDR is used to estimate the current position in the area where the visible light cannot be received and to eliminate the cumulative position error and compensate the current position in the area where the visible light can be received. Smartphone users can use the smartphone application based on augmented reality to check the position information and receive route guidance to a destination. Experimental setup including LED lights was installed in the room to verify the performance of the proposed system by experiment.
