At the same time, the key technology of VPES is analyzed and technical project on realizing VPES system is proposed. As a example, a set of "load forecasting system of fatigue strength for light truck spare wheel" is established successfully. 论述了虚拟原型实验仿真的研究意义 ,综合归纳了VPES技术的研究内容 ,并对VPES的关键技术进行了分析研究 ,提出了VPES系统实现的技术方案 ,并以一汽车产品为例 ,建立了一套“轻型卡车备用胎架疲劳强度的载荷预测”虚拟原型实验仿真系统。 In the field of content-based retrieval,browsing is a good choice while retrieval is often hard. VideoCAR is a Video Content Analysis and Representation system developed at NUDT. This paper discusses the design and implementation details of content-based video browsing interface in VideoCAR,including the implementation of content navigation and content representation mechanism under the restriction of limit screen space,and the implementation of browsing mechanism helping people locate interested parts at...

This paper discusses the design and implementation details of content-based video browsing interface in VideoCAR,including the implementation of content navigation and content representation mechanism under the restriction of limit screen space,and the implementation of browsing mechanism helping people locate interested parts at any video hierarchy. Object-oriented method and ActiveX controls in MFC are used to save developing efforts. 基于内容的视频浏览是在基于内容视频检索领域中,技术现状无法满足应用需求情况下的一种折衷手段。VideoCAR是我们设计的一个用于视频内容分析与表现的原型实验平台。在该系统的界面设计中我们充分利用面向对象的设计思想和 MFC提供的各种ActiveX控件,解决了在屏幕空间有限的条件下提供有效导航机制和高效内容表现的问题,提供了多种浏览手段,帮助用户在各个层次上快速定位感兴趣的视频资料。本文介绍了该系统界面的设计要点和主要实现方法。
