本文提出了一种新的室外混合现实系统，设计的人谁携带一个摄像头附加的小型手持设备在室外场景中，其中嵌入了一些监控摄像头。我们提出了一个新的功能，在户外混合现实，方便的设备可以显示一些结构，如建筑物，墙壁等隐藏的不可见区域的实时状态。该功能是实现在一个摄像头连接，小型便携式笔记本电脑（HPC）。不可见区域的视频由监控摄像机拍摄，并且它们精确地重叠在HPC摄像机的视频上，因此用户可以注意到不可见区域中的对象并直接看到对象的行为。监控摄像头有两个用途。(1)他们获取看不见的区域的视频。视频被修剪和扭曲，以便将它们强加到HPC摄像机的视频中。(2)它们还用于更新校准标记的纹理，以便处理真实的户外世界中可能的纹理变化。我们已经实现了一个初步的系统与四个监控摄像头，并证明我们的系统可以可视化不可见的地区在真实的时间。
This paper presents a new outdoor mixed-reality system designed for people who carry a camera-attached small handy device in an outdoor scene where a number of surveillance cameras are embedded. We propose a new functionality in outdoor mixed reality that the handy device can display live status of invisible areas hidden by some structures such as buildings, walls, etc. The function is implemented on a camera-attached, small handy subnotebook PC (HPC). The videos of the invisible areas are taken by surveillance cameras and they are precisely overlapped on the video of HPC camera, hence a user can notice objects in the invisible areas and see directly what the objects do. We utilize surveillance cameras for two purposes. (1) They obtain videos of invisible areas. The videos are trimmed and warped so as to impose them into the video of the HPC camera. (2) They are also used for updating textures of calibration markers in order to handle possible texture changes in real outdoor world. We have implemented a preliminary system with four surveillance cameras and proved that our system can visualize invisible areas in real time.
