Position Estimation Method Using RGB Values of LED Colour Temperature in a Fuzzy Logic System

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
This study proposes a novel LED‐based positioning system that estimates two‐dimensional position by analysing the chromaticity and frequency components (via FFT) of indoor lighting in tunnel environments where GPS signals are blocked. Experimental results demonstrate that the proposed method achieves reliable positioning accuracy within 5 cm in ...
