Query: A High Coverage Camera Assisted Received Signal Strength Ratio Algorithm
  for Indoor Visible Light Positioning   In this paper, a high coverage algorithm termed enhanced camera assisted
received signal strength ratio (eCA-RSSR) positioning algorithm is proposed for
visible light positioning (VLP) systems. The basic idea of eCA-RSSR is to
utilize visual information captured by the camera to estimate the incidence
angles of visible lights first. Based on the incidence angles, eCA-RSSR
utilizes the received signal strength ratio (RSSR) calculated by the photodiode
(PD) to estimate the ratios of the distances between the LEDs and the receiver.
Based on an Euclidean plane geometry theorem, eCA-RSSR transforms the ratios of
the distances into the absolute values. In this way, eCA-RSSR only requires 3
LEDs for both orientation-free 2D and 3D positioning, implying that eCA-RSSR
can achieve high coverage. Based on the absolute values of the distances, the
linear least square method is employed to estimate the position of the
receiver. Therefore, for the receiver having a small distance between the PD
and the camera, the accuracy of eCA-RSSR does not depend on the starting values
of the non-linear least square method and the complexity of eCA-RSSR is low.
Furthermore, since the distance between the PD and camera can significantly
affect the performance of eCA-RSSR, we further propose a compensation algorithm
for eCA-RSSR based on the single-view geometry. Simulation results show that
eCA-RSSR can achieve centimeter-level accuracy over 80% indoor area for both
the receivers having a small and a large distance between the PD and the
camera.
