School of Information Engineering,Wuhan University ofTechnology,Hubei Wuhan 430070) Abstract: As a combination of lighting and optical communication, to broaden the spectrum resource , green energy-saving new wire less communication techno logy, LED visible light communication (VLC) technology based application in indoor positioning system has recently become a veηhot research topic . The domestic and foreign research on LED visible light communication in indoor positioning technology is divided into non-imaging positioning technology and imaging positioning technology. Among them , there are four non-imaging positioning technology methods: triangulation method , scenario analysis, proximity method and hybrid techniques with VLC andAd Hωwireless network . This article provides an overview of these two technologies, and their performance are compared. Finally the outlook for future research are di scussed .
