一种基于增强现实的室内漫游系统

提出了一种基于增强现实的室内漫游系统,在这个系统中用户通过HMD观察增强的视景。在这个视景中不但包含真实布景的图像,还包含有计算机生成的虚拟物体的图像。为了实现虚实场景之间的注册,在HMD上安装有两个摄像机:场景摄像机与跟踪摄像机。并且在用户所在房间的顶部安装了一系列的红外标志点,这些标志点的图像由跟踪摄像机获取,并通过位置估计算法计算用户头部的位置和姿态。另外,通过一对安装有ARtoolKit标志点的手套,实现用户与虚拟环境之间的交互。最后,一套海底漫系统被开发出来,以验证整个漫游系统的可用性

A AR based indoor interaction system

An indoor interaction system based on Augmented Reality is presented in this paper.In this system,the user observes the scene by a HMD.Not only the real world but also the virtual objects are shown in the scene.There are two cameras mounted on the HMD,called tracking camera and scene camera.And many infrared markers are mounted on the ceiling of the room.The images of the marks are captured by the system and used to compute the pose of the head.In addition two ARtoolKit Markers are mounted on the user's glove to implement the interaction between the user and the environments.At last,a seabed tourism system is developed to test the usability of the presented system.
