基于RSSI技术的室内导航定位近些年得到了快速发展,对Wi Fi信号强度定位算法的研究是目前研究的热点。本文首先从理论上研究分析了Wi Fi信号强度用于导航定位服务的空间分辨率,说明该技术具有广泛的应用前景和挖掘潜力;然后在实际室内环境进行了试验,研究分析了Wi Fi信号强度在一维空间和二维空间的实际空间分辨率;最后在理论和实践两方面分析的基础上,初步分析说明了基于RSSI技术的室内导航定位的研究方向和重点,为未来的研究工作奠定了基础。
The indoor navigation and positioning based on the RSSI technology has been rapidly developed in recent years. The research on the Wi Fi signal strength location algorithm is currently a hot research topic. In this paper, firstly, the spatial resolution of Wi Fi signal strength for navigation and location service is studied theoretically and analyzed, which shows that the technology has a wide range of application prospects and potential for mining; and then tested in real indoor environment, studied the Wi Fi signal strength In the one-dimensional space and two-dimensional space of the actual spatial resolution; Finally, based on the analysis of both theory and practice, the preliminary analysis shows that the RSSI-based indoor navigation and positioning of the research direction and focus for the future research work laid basis.
