我们提出了一个用户定位系统，使用不可见的标记可穿戴增强现实（AR）在大型室内环境。可穿戴AR系统作为用于在真实的世界中显示基于位置的信息的新方法已经受到了极大的关注。为了使用可穿戴AR系统，有必要使用定位基础设施来测量用户的位置和取向，而没有由合并真实的和虚拟世界引起的不期望的视觉效果。此外，本地化环境的基础设施必须容易且廉价地构建。所提出的系统可以通过在天花板或墙壁上粘贴包含打印的不可见标记的壁纸来精确地估计用户的位置和方向。通过使用带有红外LED的红外摄像头识别标记来估计用户的位置和方向。为了构建定位系统的环境，我们开发了一个初始化工具，校准使用数码相机的闪光灯照明拍摄的照片的标记的对齐。
We propose a user localization system that uses invisible markers for wearable augmented reality (AR) in large indoor environments. Wearable AR systems have received a great deal of attention as a new method for displaying location-based information in the real world. For using wearable AR systems, it is necessary to measure the position and orientation of a user using a positioning infrastructure without the undesirable visual effects that arise from merging real and virtual worlds. In addition, the infrastructure of the localization environment must be constructed easily and cheaply. The proposed system can estimate the position and orientation of a user precisely by affixing wallpapers containing printed invisible markers on ceilings or walls. The user's position and orientation are estimated by recognizing the markers using an infrared camera with infrared LEDs. To construct environments for the localization system, we developed an initialization tool that calibrates the alignment of the markers from photographs taken by flash illumination using a digital still camera.
