Visible Light Positioning using Reflected Indoor Luminaries

Many visible light positioning (VLP) systems assume that a receiver (e.g. smartphone camera) can capture direct signals from multiple illumination devices, which does not always hold in real situations. In this project we propose a system receiving optical signals emitted from multiple indoor luminaries and reflected by a floor. By capturing an image of a floor using a smartphone camera and identifying intensities of reflected lights emitted from different luminaries, accurate and realtime tracking of a smartphone is confirmed to be achieved.
