户外增强现实应用将感兴趣的信息实时投射到世界视图上。他们的核心挑战是识别当前视图中存在的有意义的对象，并检索相关信息并将其叠加到这些对象上。在本文中，我们报告了移动户外增强现实应用框架的开发，该框架应用于将峰值信息叠加到山地景观视图上。最终的应用程序通过使用在线数字地形模型 (DEM) 估计从用户的角度可见的虚拟全景图，并将此类全景图与相机拍摄的实际图像进行匹配来进行操作。当找到良好的匹配时，DEM 中的元数据（例如峰值名称、海拔高度、距离）将实时投影到视图上。该应用程序除了为用户提供良好的体验外，还可以用于众包用于环境应用的带注释的山地图像集合。
Outdoor augmented reality applications project information of interest onto views of the world in real-time. Their core challenge is recognizing the meaningful objects present in the current view and retrieving and overlaying pertinent information onto such objects. In this paper we report on the development of a framework for mobile outdoor augmented reality application, applied to the overlay of peak information onto views of mountain landscapes. The resulting app operates by estimating the virtual panorama visible from the viewpoint of the user, using an online Digital Terrain Model (DEM), and by matching such panorama to the actual image framed by the camera. When a good match is found, meta-data from the DEM (e.g., peak name, altitude, distance) are projected in real time onto the view. The application, besides providing a nice experience to the user, can be employed to crowdsource the collection of annotated mountain images for environmental applications.
