Abstract

In the realm of indoor positioning, the limitations of traditional Global Positioning Systems (GPS) in terms of accuracy and availability have prompted the exploration of alternative solutions. This thesis presents a comprehensive study on enhancing indoor positioning accuracy using the K-Pairwise LED Image-Sensor-Based Visible Light Positioning (K-LED-VLP) system, aimed at overcoming the inherent limitations of GPS in indoor environments. Central to this research is the refinement of algorithms tailored for optimizing image sensor data processing and LED communication protocols within a controlled 3.6x2.7x2.7 meter environment. By employing various LED configurations, the study methodically evaluates the system’s precision, focusing on minimizing positioning errors influenced by sensor noise and environmental lighting conditions. The findings demonstrate substantial improvements in positioning accuracy and reliability, showcasing the potential of K-LED-VLP systems to provide robust indoor localization solutions. This work not only addresses critical technical challenges but also advances the field by paving the way for future innovations in precise and dependable indoor navigation technologies.
