虚拟现实技术浅析

阐述了虚拟现实（Virtual Reality,VR)技术的内涵与特点，构成与关键技术，分析了发展VR技术应重视的研究方向；（1）VR建模、人机实时交互、VR生成与逼真感，虚拟现实与真实现实一致性、多传感器数据/信息融合研究。（2）3维传感、交互设备及立体显示设备的研究；（3）VR系统开发平台及分布式VR技术研究，提出了利用多媒体和VR的集成实现攻防对抗虚拟现实的应用构想。

An Elementary Analysis of a Virtual Reality Technology

The meaning and character, composing and key technique of virtual reality (VR) are expatiated. The important fields for developing VR technique, such as the VR modeling, man-machine interaction in real tine, VR generation and verisimilitude sense, consistency in VR and actual reality, research multi-sensor data/information fusion, 3D sensing, research on interactive equipment and stereo display device, the developing platform of VR system and research on distributed VR techniques are analyzed. The tentative plan of antagonizing between attack/defence and VR realized with using integration of multimedia and VR is presented.
