摘要
为解决地下停车场GPS信号弱,现有导航定位系统成本高、误差大和效率低的问题,基于轻量化定位对地下环境的导航定位系统进行了优化,通过拓扑原理利用TOA算法与定向天线获取距离与角度信息对TOA算法进行改进,同时使用Dijkstra算法为导航定位系统进行固定路线路径规划。应用该系统优化方法能够更好地解决自行式地下停车场的导航定位问题,使定位成本和定位误差降低,提升了定位效率。
In order to solve the problems of weak GPS signal of underground parking lot that high cost,large error and low efficiency of existing navigation and positioning system,the navigation and positioning system of underground environment was optimized based on lightweight positioning,and the TOA algorithm was improved by using TOA algorithm and directional antenna to obtain distance and angle information through topology principle.Meanwhile,Dijkstra algorithm is used to plan the fixed route for the navigation and positioning system.The application of the system optimization method can better solve the navigation and positioning problem of the self-traveling underground parking lot,reduce the positioning cost and positioning error,and improve the positioning efficiency.
