【摘要】:室內(nèi)環(huán)境的復(fù)雜性遠(yuǎn)遠(yuǎn)高于室外環(huán)境,信號(hào)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(shí)現(xiàn)了一種高精度室內(nèi)定位仿真平臺(tái),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(guò)反向射線追蹤技術(shù)分析射線的直射、折射、反射、繞射過(guò)程,獲得定位點(diǎn)的徑參數(shù);再次完成信號(hào)首徑檢測(cè)并測(cè)距;最終實(shí)現(xiàn)米級(jí)定位仿真。實(shí)驗(yàn)結(jié)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(dá)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.
