摘要
投射式虚拟现实 (ProjectiveVirtualReality,PVR)是一种控制机器人及其它自动化设备的新方法 ,克服了一般临场感方法的缺陷。为减少甚至消除PVR技术中虚拟环境与真实环境之间的偏差 ,设计了一个场景处理系统 ,详细讨论了该系统的原型 ,描述了该系统的体系结构 ,介绍了实现该系统的一些关键技术。该系统综合利用了计算机视觉技术 ,能有效弥补损失的视觉信息 ,产生更加逼真的虚拟环境 ,从而进一步改善PVR系统的性能。该系统采用了组件技术进行开发 ,具有良好的可重用性与扩展性 。
In order to further reduce the errors between virtual environment and actual environment in Projective Virtual Reality(PVR)technology, a scene processing system is presented in this paper. The prototype and the architecture of the scene processing system are discussed in details, and some key technologies used to implement the system are presented. The scene processing system can efficaciously compensate the lost vision information, produce more realistic virtual environment and improve performance of PVR system by using computer vision technologies comprehensively. Because it is developed with component technology, the system has good reusability and augmentability. The system also implements distributed network application with CORBA technology.
