摘要
随着城市化进程加速,各种大型立交桥、高架路、大型室内停车场等建筑遮蔽空间越来越多,同时遮蔽空间内停车导航需求也日益增长。传统卫星导航因信号遮蔽原因导致在遮蔽空间内卫星信号缺失,且遮蔽物干扰使定位精度不足,无法进行室内导航定位。蓝牙到达角(AOA)技术凭借其亚米级定位精度,以及低功耗、低成本、易部署和穿透性优势成为遮蔽空间内导航定位的核心解决方案。对此,文章探讨了AOA在室内遮蔽空间内导航定位中的实际应用价值,并分析如何利用AOA技术提升地图导航定位精度。
With the acceleration of urbanization,there are more and more building shelters such as large overpasses,elevated roads,and large indoor parking lots,and the demand for parking navigation within these shelters is also increasing.Traditional satellite navigation suffers from signal occlusion,resulting in missing satellite signals in the occluded space,and interference from occluded objects leads to insufficient positioning accuracy,making indoor navigation and positioning impossible.Bluetooth Angle of Arrival(AOA)technology has become the core solution for navigation and positioning in shaded spaces due to its sub meter level positioning accuracy,as well as its advantages of low power consumption,low cost,easy deployment,and penetration.In this regard,the article explores the practical application value of AOA in indoor sheltered space navigation and positioning,and analyzes how to use AOA technology to improve map navigation and positioning accuracy.
