摘要
伴随着全球互联网信息时代的到来,导航系统与通信系统的结合日益紧密,通信与行人航迹在信息交融中不断迅速发展。为了获取更精准的行人运动航迹,文中使用了惯性测量模块(Inertial Measurement Unit,IMU)辅助行人运动轨迹。由于IMU惯性测量元件自身存在惯性漂移情况,导致在行人航向角推算中会产生大量误差。因此,文中研究了基于IMU模块航向角误差修正算法,大大提高了运动轨迹的精度。
With the advent of the global internet information age,The combination of navigation information and communication system is increasingly close,Communication and pedestrian track are developing rapidly in the integration of information.In order to obtain more accurate pedestrian movement track.In this paper,the inertial measurement module(Inertial Measurement Unit,IMU)assisted the pedestrian motion trajectory.Because of inertial drift of the IMU inertial measurement element itself,so in pedestrian heading estimation will produce a large number of errors.Therefore,this paper studies the error correction algorithm based on the IMU module,which greatly improves the trajectory accuracy.
