Indoor Visible Light Positioning Technology

Visible light positioning (VLP) uses LED lamps for lighting to achieve indoor high-precision positioning, which has the preferences of cost-effective, no electromagnetic intermeddling, high security, and convenient deployment. In this paper, firstly, the indoor positioning system and routine visible light positioning algorithms are retrospected, and the current development status is acquainted. Then, some pivotal technologies to embellish the performance of the overall positioning system are discussed, which provides a footing for further research on the white LED indoor location system. Finally, on account of the subsisting research results, the future research direction of indoor visible light positioning technology is put forward.
