    Abstract

    In order to achieve low-cost, low-complexity and high-precision indoor localization system, we propose a fingerprint based visible light indoor localization method. In the method, the light emmiting diode (LED) is employed as the transmitter. Based on the received signal strengths (RSS) of visible light, the triangulation method and fingerprint based hybrid positioning algorithm are combined to achieve indoor high precision localization. The proposed method can be divided into two phases. First, the triangulation method is used to obtain the coarse range of the mobile terminal (MT). Then, the fingerprint based method which is constrained by the coarse range is used to get a fine estimate of the MT. Experimental results show that the averaged positioning error of the proposed method is improved by 64.71% compared with that of the traditional RSS based visible light indoor localization method. Besides, the proposed method can achieve better localization performance at lower computational complexity compared with the traditional fingerprint based method.
