【摘要】：室內(nèi)環(huán)境的復雜性遠遠高于室外環(huán)境,信號的多徑傳播為室內(nèi)定位精度提出了極大挑戰(zhàn)。本文提出和實現(xiàn)了一種高精度室內(nèi)定位仿真平臺,用于模擬室內(nèi)高精度定位。該仿真系統(tǒng)首先生成三維可視化的定位空間;其次通過反向射線追蹤技術分析射線的直射、折射、反射、繞射過程,獲得定位點的徑參數(shù);再次完成信號首徑檢測并測距;最終實現(xiàn)米級定位仿真。實驗結果顯示系統(tǒng)在多徑環(huán)境下,以75%的概率定位誤差可以達到3米以內(nèi)。
[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.
