基于帧流可控制的环境训练系统

A Training System on the Basis of Controlled Frames of Stream Media

开发基于虚拟现实概念的环境训练系统具有广泛的应用前景。针对不同的应用,使用的开发工具、实现途径各不相同。目前比较常见的手段是利用计算机强大的运算能力,实现三维实体成像即生成虚拟环境,在传感器配合下实现训练目标。考虑到研发成本和系统本身的复杂性,本系统中非建模目标部位的动态跟踪采用半人工的方式预先处理,采用巧妙的方法实现了非建模目标部位的动态跟踪。降低了系统难度,满足了系统要求。在数据处理方面通过巧妙的构思减少了数据量,加快了系统处理速度。利用Windows Media Player SDK实现了媒体播放流的无缝切换。

There are numerous ways and tools to develop Real-Time training system based on the theory of Virtual-Reality. Most of them generate VR environment by building up 3D models of objects, and use some sensors to provide human-computer interaction. In this paper, a novel stream media is applied to generate VR environment. The system preprocess the frames, uses an intelligent procedure to trace the target of stream media, switches the media stream in real-time without delay or glint, and thus provides the VR training systems.
