摘要
随着智慧城市建设与城市化进程加速,大型室内场景日益增多,高精度室内定位需求愈发迫切。然而,室内环境复杂易导致信号衰减与传感器噪声干扰,传统单一源定位方法及传统融合技术在定位精度、鲁棒性及实时性方面存在局限。智能手机作为便携终端,具备集成多传感器与通信模块的硬件优势。为此,文章针对行人航位推算(PDR)中的步数统计、步长估计及航向估计等关键问题,提出一种基于智能手机PDR与阵列天线的融合定位算法。实验结果表明,该算法相较于传统方案显著提升了定位精度,在复杂室内环境中实现了更高的稳定性与实时性,为高精度室内定位技术的发展提供了新方向。
With the acceleration of smart city construction and urbanization,large indoor scenes increase day by day,and the demand for high-precision indoor positioning becomes increasingly urgent.However,the complex indoor environment easily leads to signal attenuation and sensor noise interference.Traditional single-source positioning methods and traditional fusion technologies have limitations in positioning accuracy,robustness,and real-time performance.As a portable terminal,the smartphone possesses the hardware advantage of integrating multi-sensors and communication modules.Therefore,aiming at key issues such as step counting,step length estimation,and heading estimation in Pedestrian Dead Reckoning(PDR),this paper proposes a fusion positioning algorithm based on smartphone PDR and array antenna.Experimental results show that compared with traditional schemes,this algorithm significantly improves positioning accuracy,achieves higher stability and realtime performance in complex indoor environments,and provides a new direction for the development of high-precision indoor positioning technology.
