摘要:
为了解决室内外无缝定位问题,基于北斗空间导航信号特征,并结合Wi-Fi指纹库定位算法,设计出一种基于北斗的室内外无缝定位系统。本系统无需改造现有Wi-Fi热点软硬件,首先利用空间均值滤波方法对采集的接收信号强度值进行平滑处理,提高信号采集的精度,然后将实际测量法精度高的优势和路径损耗模型法灵活易更新的特点相结合,设计了一种室内定位精度优于5.5 m,室内外定位模式切换时间小于10 s的无缝定位系统,满足了室内外导航定位应用的需求。
Abstract:
Aiming at indoor and outdoor seamless localization problems, a new positioning system based on the characteristics of Beidou spatial navigation signal and the location algorithm of the Wi-Fi fingerprint were presented. This system did not need to transform the existing Wi-Fi hotspots’ hardware and software. First the spatial mean filtering method was used to the collected received signal strength indicator(RSSI)signals for smoothing processing in order to enhance the signals’ precision, then the actual measurement method with high precision and the path loss model method with flexible updating capacity were combined when the system was designed. The switching time of seamless positioning system localization mode was less than 10 seconds and indoor positioning accuracy is better than 5.5 meters, which satisfies the requirement of indoor and outdoor navigation in positioning application.
