摘　　要：随着室内定位技术的不断发展,室内导航渐渐成为可能。但由于室内定位精度和稳定性较差,导致定位点漂移,导航引导错误,用户体验感差,无法满足室内精细导航需求。文中根据室内空间的特点,结合GIS空间分析与导航推测算法,设计出一种适合室内定位约束与优化算法,能在不影响定位效率的情况下很大程度上改善定位效果。经实际场地实验,效果良好。With the continuous development of indoor positioning technology ,indoor navigation becomes possible gradually .But due to the low accuracy and poor stability of indoor positioning ,the drift of positioning points ,guiding the navigation error ,and less user‐friendly effect ,cannot meet the fine interior navigation requirements .This paper ,combined with GIS spatial analysis and reckoning algorithm ,designs a suitable indoor positioning constraints and optimization algorithm based on the characteristics of the indoor space ,w hich can greatly improve the positioning performance .T hrought the experiments ,the effect proves good .
