摘　　要：相比平面地图导航,AR导航是一种新型的导航方式,但室内AR导航还未完全成熟。针对目前室内AR导航定位方法和导航效果不理想的问题,提出一种基于AR标识图,结合视觉测距优化定位结果的方法,同时还提出基于深度图实现虚实遮挡的方法计算虚拟路径和真实环境的空间遮挡关系,打造虚实无缝融合的AR导航体验。基于这两种方法,使用Unity3D引擎开发了室内AR导航系统,系统使用AR标识图结合视觉测距进行定位,使用深度图实现虚实遮挡,使用Unity的AI寻路组件计算导航路径。实验结果证明:该室内AR导航方案适用于类似图书馆等室内场所。AR navigation is a novel alternative to flat-map navigation,but AR navigation is not yet fully mature.To address the current situation that indoor AR navigation positioning methods and navigation effects are not ideal,a method is proposed to optimize positioning results based on AR marker map combined with visual ranging,and a method is also proposed to calculate the spatial occlusion relationship between virtual road signs and real environment based on depth map to realize virtual and real occlusion,so as to create a seamless integration of virtual and real AR navigation experience.Based on these two methods,the Unity3D engine is adopted to develop an AR navigation system.In the proposed system,the AR marker map combined with visual ranging is used to perform localization,the depth map is used to perform virtual-real occlusion,and AI pathfinding component of Unity is used to calculate the navigation path.The experiment results demonstrate the applicability of the proposed system is suitable for indoor places like libraries.
