[Abstract]:In this paper, a method of realizing indoor positioning of visible light based on intelligent mobile terminal is presented. The method acquires light emitting diode light source label and image information through terminal imaging module, according to the imaging position relation and image focal length between light sources. The coordinate of terminal position is calculated by geometric optical imaging principle. The nonlinear system model is established by the visible light imaging positioning system model and the geometric optical imaging principle. The final position calculation is accomplished by using the improved lossless Kalman filter algorithm. The feasibility of the proposed method is verified by both theoretical simulation and experimental system. The data show that the method can achieve high precision indoor positioning at the decimeter level.
