A Scanning-Based Indoor Optical Wireless Positioning System with Single VCSEL
🤖 AI Summary
This work proposes a three-dimensional indoor visible light positioning system that overcomes the hardware complexity and high cost of conventional multi-transmitter approaches by employing a single vertically-cavity surface-emitting laser (VCSEL) mounted at the ceiling center. The system achieves high-precision localization through two-dimensional beam scanning with 1° angular resolution in both azimuth and elevation, fusing angle-of-arrival (AoA) and received signal strength (RSS) information. This design substantially simplifies system architecture and reduces implementation cost while delivering sub-centimeter positioning accuracy at most test points in simulation, outperforming existing multi-transmitter visible light positioning schemes.

📝 Abstract
This paper presents a novel indoor visible light positioning (VLP) system utilising one vertical-cavity surface-emitting laser installed at the ceiling centre of a space. The system offers three-dimensional localisation by sweeping through space at one-degree resolution in two dimensions (azimuth and elevation), significantly simplifying hardware. Through incorporating the angle of arrival and received signal strength, this system demonstrates excellent precision in indoor positioning. Simulation results verify that the system attains sub-centimetre precision for most test points, outperforming conventional multi-transmitter VLP schemes in cost-efficiency and simplicity.
