Abstract:Visible light communication (VLC) is a wireless technology that can achieve power efficient wireless communication at high data rates. One attractive use case of VLC is for indoor positioning, where it is possible to achieve centimeter level accuracy. Many applications in industry require accurate and private indoor positioning. In particular, the use of unmanned aerial vehicles (UAVs) has recently gained interest for related applications involving warehouse management but requires precise localization that can be expensive to achieve with RF technologies. Visible light positioning (VLP) offers great potential for industrial applications involving UAVs due to its power efficiency and high accuracy, but the topic remains largely unexplored. In this thesis, we provide a thorough analysis of state-of-the-art VLP methods, and identify the best alternatives considering the limitations of a constrained drone environment. Then, we propose a novel framework, Firefly, to provide localization using inertial and barometric sensors available in drones. Our framework is the first to provide 3D drone localization with light and we evaluate it in an experimental setup. We show that the proposed approach allows to locate the drone within a few decimeters of the actual position and reduces the localization error by 42% compared to state-of-the-art positioning methods.
