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

在这个项目中，我们获得了以下研究成果：真实世界和虚拟世界的几何配准构建增强现实环境中最重要的问题之一是真实和虚拟坐标系的对齐。这一几何配准问题，导致估计用户的观点在现实世界中的位置和方向，首先得到解决，并研究了一些技术；例如：(1)通过跟踪用户视野中的标记物和自然特征，实现基于视觉的配准；(2)将惯性传感器输出与基于视觉的跟踪相结合，实现鲁棒配准；(3)利用IrDA设备和RFID标签等定位基础设施进行位置识别；(4)在室外环境中集成GPS和惯性传感器。我们已经开发了一个两步信息表示方案，用于在真实世界对象上覆盖注释。首先，将物体标签叠加到用户视野中的n个物体上，然后针对用户眼睛注视的某一物体呈现详细的信息。此外，我们还开发了一个实时更新标注信息的网络化数据库系统。该系统通过无线网络向用户提供来自服务器的注释信息，因此用户不需要将其保存在可穿戴计算机中，信息提供者可以通过网络浏览器轻松更新数据库。使用这个框架，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。原型系统的开发许多可穿戴增强现实系统的原型已经开发出来。这些系统被实现为视频透明增强现实系统，其中注释首先与在用户视点捕获的真实世界图像组成，然后合成图像通过头戴式显示器或附加在眼镜上的小型夹式显示器呈现给用户。通过室内和室外环境实验验证了所提出系统的可行性。其中一些系统被调整为特定的潜在应用，例如消防中的消防员辅助系统和观光中的导游系统。少
