Abstract

Abstract: The result of coded-light positioning system is usually discontinuous and has large error in a non-line-of-sight environment. Aiming at this problem, an indoor positioning method of coded light+PDR combination for smartphones is proposed. This method fuses the results of coded-light positioning system and PDR by EKF. And it uses innovation to build a robust filter. Several walking tests show that the method can solve the problem effectively and achieve the goal of continuous and high-precision indoor pedestrian positioning.

Key words: coded-light positioning, PDR, EKF, robust filter
