Abstract

We present a mobile augmented reality system for outdoor annotation of the real world. To reduce user burden, we use aerial photographs in addition to the wearable system's usual data sources (position, orientation, camera and user input). This allows the user to accurately annotate 3D features with only a few simple interactions from a single position by aligning features in both their first-person viewpoint and in the aerial view. We examine three types of aerial photograph features - corners, edges, and regions - that are suitable for a wide variety of useful mobile augmented reality applications, and are easily visible on aerial photographs. By using aerial photographs in combination with wearable augmented reality, we are able to achieve much higher accuracy 3D annotation positions than was previously possible from a single user location.
使用航空照片改进移动AR注释
我们提出了一种移动增强现实系统,用于户外对现实世界的标注。为了减轻用户负担,除了可穿戴系统的常用数据源(位置、方向、相机和用户输入)外,我们还使用了航空照片。这允许用户通过调整他们的第一人称视角和鸟瞰图中的特征,从单一位置通过几个简单的交互来准确地注释3D特征。我们研究了三种类型的航空照片特征——角、边和区域——它们适用于各种有用的移动增强现实应用,并且很容易在航空照片上看到。通过将航空照片与可穿戴增强现实技术相结合,我们能够获得比以前单一用户位置更高精度的3D注释位置。
