【摘要】：行人定位导航是为公众出行提供准确位置信息及导航服务的应用系统。目前,全球卫星定位技术(GNSS)在室外导航与位置服务产业得到成熟应用;然而,由于室内遮挡与多路径效应的存在,GNSS难以提供准确可靠的室内定位信息,阻碍了导航服务向室内范围的拓展。研究准确、稳定、低成本的室内导航技术,能够拓展室内地图服务的应用范围,为提高居民的出行质量,促进导航与位置服务产业的发展提供关键技术支撑。本文的研究目的在实景导航的基础上融入增强现实技术,将虚拟与现实信息相互融合,提高用户在室内导航过程中的体验感和实时代入感,降低室内寻路与导航负担。本文的研究对象是室内导航系统,在室内导航需求明显增加的背景下,研究了基于AR的室内实景导航方法,并基于安卓智能手机对所提出方法进行了实现。本文研究内容主要包含两个部分:(1)基于AR的室内实景导航方法研究,包括室内行人路网构建、室内多楼层路径规划及室内实景增强导航方法;(2)基于安卓开发环境的室内AR实景导航软件开发,实现了所研究的室内导航方法,主要包括电子地图、定位、基于AR的实景导航、店铺平面和全景图预览等模块。经过测试,该导航系统应用效果较好,实现了室内多层楼地图显示、POI信息查询、室内全景浏览、多楼层路径规划以及实时AR增强路径引导等功能,能够良好地完成室内行人导航任务。
[Abstract]:Pedestrian positioning navigation is an application system that provides accurate location information and navigation services for public travel. At present, GNSS-based global positioning technology is widely used in the outdoor navigation and location service industry; however, Because of the existence of indoor occlusion and multipath effect, GNSS is difficult to provide accurate and reliable indoor positioning information, which hinders the expansion of navigation services to indoor scope. It can expand the application range of indoor map service, improve the travel quality of residents and promote the development of navigation and location service industry. The virtual and realistic information are combined to improve the user's experience and real-time substitution in the process of indoor navigation, and to reduce the burden of indoor road finding and navigation. The research object of this paper is the indoor navigation system. In the background of the obvious increase of indoor navigation demand, the indoor real scene navigation method based on AR is studied. This paper mainly includes two parts: 1) the indoor real scene navigation method based on AR, including the construction of indoor pedestrian network. The indoor AR real scene navigation software based on the Android development environment is developed, which mainly includes electronic map, positioning, real scene navigation based on AR. After testing, the navigation system has a good application effect, and realizes the indoor multi-floor map display POI information query, indoor panoramic browsing, Multi-floor path planning and real-time AR enhanced path guidance can accomplish indoor pedestrian navigation tasks well.
