A New VLC Localization System with the Assistance of RGB-D Camera

摘要

Recently, many technologies such as Wi-Fi, camera, visible light, simultaneous localization and mapping(SLAM) are utilized to achieve high accuracy indoor localization. Using the visible light communication(VLC) technology, we can modulate light-emitting diode (LED) lights so that it can be adapted for localization as well as illumination, which is low-cost and practical. In this paper, we propose a new hybrid method, whose principle is using RGB-D camera to recognize the characteristics of the circumstance as the assistance of VLC positioning. The computer vision technology is employed to process the information captured by the RGB-D camera to help VLC positioning system derive a high accuracy location. Experiment results show that our sensor fusion positioning system is computationally efficient, and it can achieve one centimeter precision.
