3D Visible Light Positioning of an Angle Diverse Receiver based on Track Analysis

We present an approach to enable 3D Visible Light Positioning (VLP) utilizing the fingerprinting method combined with the approach of track analysis. Especially in rooms with a highly symmetric arrangement of the luminaires, fingerprinting suffers from high ambiguity of the received signals. We demonstrate an approach to overcome this ambiguity by expanding fingerprinting by track analysis in 3D VLP based on angle diverse receivers. Furthermore, we give a more detailed insight on the impact of the number and the kind of the segmentations of the related optical elements for the receivers and their effect on the performance of the designed algorithm. We demonstrate that by such an approach the success rate for correct 3D position estimation can be enhanced between 29 % and 64 % in dependence of the respective angular segmentation of the receiver.
