Abstract

In view of the problem that low positioning accuracy of dense pedestrians and high density requirement of UWB base stations in complex indoor environment, this paper developed a three-dimensional cooperative location algorithm for dense pedestrians based on UWB. Firstly, it used clustering algorithm to suppress the large non-line-of-sight(NLOS) error in the ranging data, and suppressed the standard measurement error with the Gaussian mean mixture filtering. Then, it proposed a two-layer cooperative positioning algorithm, established a co-localization mathematical model and combined iterative initial value acquisition strategies for initial localization, which reduced the requirement for number of base stations. After screening the ranging data with smaller NLOS errors and correcting them, it performed secondary positioning. Finally, considering the high mobility of pedestrians, it designed an interactive multi-model Kalman filter algorithm to alleviate the problem of jumps in positioning results. Experimental results show that the positioning accuracy of the proposed algorithm is 0.11 m in weak NLOS environment and 0.17 m in strong NLOS environment respectively, which has a higher positioning accuracy compared with other algorithms and further reduces the requirement for UWB base station density.
