Positioning Error Analysis of Indoor Visible Light Positioning Using Dual Cameras

Abstract

We analyze the mean squared positioning error of the visible light positioning system with dual cameras. We also build up a experimental system to test the real positioning error. It can be observed that the positioning error along the direction vertical to the line connecting the two cameras is significantly larger than that parallel to such line, and can be well predicted by that from the theoretical analysis. Moreover, we have adopted Gaussian mixture model for the positioning error, which show that two components suffice.
