项目摘要

We have obtained the following research results in this project.1.Geometric Registration of Real and Virtual WorldsOne of the most important problems in constructing augmented reality environments is to align the real and virtual coordinate systems. This geometric registration problem, which results in estimating the position and orientation of user's view point in the real world, was first addressed and a number of techniques have been investigated ; for example, (1)Vision-based registration by tracking markers and natural features in user's view, (2)Integration of inertial sensor output with vision-based tracking for robust registration, (3)Position identification using positioning infrastructures such IrDA devices and RFID tags, and (4)Integration of GPS and inertial sensors in outdoor environments.2.Annotation Overlay on Real World ObjectsWe have developed a two-step information presentation scheme for overlaying annotations on real world objects. First object labels are overlaid o … More n objects in user's view, and detailed information is then presented with respect to a certain object on which user's eyes are fixed. Moreover we have developed a networked *ase system for updating annotation information in real-time. The proposed system provides users with annotation information from a server via a wireless network so that users do not need to hold it in their wearable computers and information providers can easily update the database with a web browser. Using this framework, multiple users can send and share location-dependent information in the real world.3.Development of Prototype SystemsA number of prototypes of wearabla augmented reality system have been developed. These systems are implemented as video see-through augmented reality systems, in which annotations are first composed with real world images captured at user's view point and then the composite images are presented to users via a head-mounted display or a small clip-on display attached to glasses. The feasibility of the proposed systems is tested with experiments in indoor and outdoor environments. Some of the systems are tuned to specified potential applications such as a fireman supporting system in fire fighting and a tour guide system in sightseeing. Less

我们在该项目中获得了以下研究结果。1。在构建增强现实环境中最重要问题的真实和虚拟世界的几何注册是使真实和虚拟坐标系统保持一致。首次解决了这种几何注册问题，从而估计了用户视点在现实世界中的位置和方向，并研究了许多技术。例如，（1）通过跟踪标记和用户视图中的自然特征的基于视觉的注册，（2）将惯性传感器输出与基于视觉的跟踪集成，以实现稳健注册的基于视觉的跟踪，（3）使用IRDA设备和RFID等定位基础设施的位置识别，例如IRDA设备和RFID标签，以及（4）在室外环境中的整合室内偏爱室外的环境。覆盖现实世界对象注释的方案。第一个对象标签被覆盖了o…在用户视图中更多的n个对象，然后就某个对象固定了用户眼睛的某个对象，介绍了详细信息。此外，我们开发了一个网络 *ASE系统，用于实时更新注释信息。提出的系统通过无线网络向用户提供了从服务器提供的注释信息，因此用户无需将其保存在可穿戴的计算机中，并且信息提供商可以轻松地使用Web浏览器更新数据库。使用此框架，多个用户可以在现实世界中发送和共享与位置相关的信息。这些系统被实现为视频透明的增强现实系统，其中首先由在用户视点处捕获的现实世界图像组成，然后通过头部安装的显示或附加在玻璃上附加的小型剪贴显示显示给用户。在室内和室外环境中，通过实验测试了所提出的系统的可行性。其中一些系统被调整为指定的潜在应用，例如消防人员中的消防员支持系统和观光过程中的导游系统。较少的
