Abstract

Abstract: The technology of visible light positioning (VLP) has the advantages of low cost, high precision, no electromagnetic interference, convenient deployment, and the advantage of taking into account both communication positioning and lighting which makes this technology has potentially useful application prospects in the field of indoor positioning. In this paper, two indoor positioning methods based on visible light communication (VLC) called imaging and non-imaging method are summarized, meanwhile, their key technologies, research development,applications and trend are analyzed and discussed. A VLP light source matching identification method based on autocorrelation sequence is proposed, what's more, a method of constructing a positioning system based on the common imaging sensor and rectangular flat-panel light source is introduced. Finally, the research and development direction of indoor VLP technology is prospected.

Key words: visible light communication, indoor positioning, key technology, autocorrelation sequence, LED_ID recognition, imaging positioning
