基于VR技术的太空授课虚拟仿真实验系统开发

Development of Space Teaching Virtual Simulation Experiment System Based on VR Technology

我国航天员两次太空授课不仅向广大青少年介绍了中国空间站工作生活场景,对失重环境下的物理现象进行科普教育,还彰显了我国强盛的科技实力。学习者囿于物理空间条件的限制,无法体验上述内容。因此,基于虚拟现实技术开发太空授课虚拟仿真实验系统,运用三维建模技术搭建中国空间站虚拟场景,在手势识别技术的支持下还原2次太空授课涉及的5种物理实验,帮助学习者认识和理解相关现象与知识、感受我国航空航天技术实力,激发民族自尊心和自豪感。

The two space lectures in China have taught young people about life on the Chinese space station and the physical phenomena in a weightless environment,andalso demonstrated the country’s strong technological capabilities.However,learners are not able to experience this content in the flesh due to the constraints of physical space.Therefore,the virtual simulation experiment system for space lectures is developed based on virtual reality technology.We use 3 D modelling technology to build a realistic virtual scene of the Chinese space station and restore the five physical experiments involved in the two space lectures with the support of gesture recognition technology.These can help learners to recognize and understand the relevant phenomena and knowledge,feel the strength of China’s developed aerospace technology and inspire their national pride and self-esteem.
