基于多技术融合的室内外无缝定位系统研究

Research on indoor and outdoor seamless positioning system based on multi-tech integration

随着现代化产业的蓬勃发展,定位应用越来越普及,室内外融合定位将成为必然发展趋势。但是室内定位与室外定位相对独立,在室内外交界区域的复杂环境下,室内外切换过程中的时延、频繁切换现象尚未得到有效解决,极大影响用户体验。文章提出了一种室内和室外定位技术相融合的方案,将PDR与GNSS、5G、UWB、伪卫星等定位方式相结合,用于实现室内外定位“无缝衔接”,做到用户在室内外移动无感知。解决在室内外中间地带定位技术切换时产生的波动现象以及误判的可能,实现更稳定和可靠的位置服务。

With the vigorous development of modern industry,positioning application is becoming more and morc popular,and indoor and outdoor integration positioning will become an inevitable development trend.However,indoor positioning and outdoor positioning are relatively independent.In the complex environment of the indoor and outdoor border area,the delay and frequent switching phenomenon in the process of indoor and outdoor switching have not been effectively solved,which greatly affects the user experience.The paper proposes a scheme of integrating indoor and outdoor positioning technology,combining PDR with GNSS,5G,UWB,pscudo satellite and other positioning mcthods,to achieve"seamless conncction"between indoor and outdoor positioning,so that users move indoor and outdoor mobile without erception.Solve the fluctuation phenomenon and the possibility of misjudgment in the positioning technology switch in the indoor and outdoor middle zone,so as to achicve a more stable and reliable location service.
