基于虚拟现实的实验系统的设计及应用研究

Research on Design and Application of Virtual Reality in Experimental System

信息技术日新月异,随之而来的各种技术、软件系统应用也处在不断更新中,因此传统实验系统已不能满足当前用户需求,很多模块需要新的思想来解决。针对虚拟现实技术特点以及实验模块的单一性,提出利用虚拟现实技术实现多实验思想搭建实验系统平台。根据上述思想,首先设计虚拟实验平台的总体框架,并针对框架部分简要说明,然后设计虚拟实验系统实现框架,最后设计虚拟实验案例,即球体的平抛运动为例制作,制作中涉及碰撞检测、交互设计和建模技术等。应用实验对比法,即虚实两种实验数据对比。根据实验数据结果,虚实两种实验数据基本相同。结论,验证了改进后的多种实验的虚拟实验系统的可行性。

With the increasing development of computer technology,the traditional virtual experimental system haven＇t satisfied users＇ demands and a lot of system need to be improved. According to the unicity of virtual experimental system,the paper proposes a multi-experiment idea to construct virtual reality experiment platform based on virtual reality technology. According to the thought,first the total framework of virtual experimental platform is designed,then the implementation framework of virtual experimental system is projected,finally the virtual experimental case is planned. The case deals with the instrument＇s modeling techniques of virtual experiment,interaction design and collision detection. Experimental data shows that virtual experiment is almost the same results like actual experiment. Therefore it is concluded that the improved virtual experimental system property is greatly enhanced and experimental effect is better,compared with the traditional and that experimental data validates the feasibility of virtual experimental system.
