【摘要】：室内环境的复杂性远远高于室外环境,信号的多径传播为室内定位精度提出了极大挑战。本文提出和实现了一种高精度室内定位仿真平台,用于模拟室内高精度定位。该仿真系统首先生成三维可视化的定位空间;其次通过反向射线追踪技术分析射线的直射、折射、反射、绕射过程,获得定位点的径参数;再次完成信号首径检测并测距;最终实现米级定位仿真。实验结果显示系统在多径环境下,以75%的概率定位误差可以达到3米以内。
[Abstract]:The complexity of indoor environment is much higher than that of outdoor environment. The multipath propagation of signals poses a great challenge to indoor positioning accuracy. A high precision indoor positioning simulation platform is proposed and implemented in this paper. The simulation system first generates a three-dimensional visual positioning space, secondly, analyzes the direct, refraction, reflection and diffraction process of the ray through the reverse ray tracing technology, obtains the diameter parameters of the positioning point, and then completes the signal head diameter detection and ranging. Finally, the meter level positioning simulation is realized. The experimental results show that the positioning error of the system can reach less than 3 meters with 75% probability in multipath environment.
