沉浸式虚拟校园仿真系统开发及关键技术研究

Research on the development and key technologies of immersive virtual campus simulation system

虚拟现实技术可以给人带来身临其境之感,传统的虚拟现实系统大多采用桌面式虚拟现实方式,沉浸感不强,交互性差,不能让体验者沉浸在虚拟系统中。综合这些因素,文章根据三维虚拟校园仿真系统需求,设计实现了基于Unity3D平台的沉浸式虚拟校园漫游系统,并研究沉浸式虚拟校园开发中所使用的关键技术。实验表明,该系统能克服虚拟漫游沉浸感不足的缺点,用户可以体验到与真实校园相近的虚拟环境,并且可以与虚拟环境进行交互。该系统具有简单和易实现等特点,拥有广阔的应用前景。

Virtual reality technology can bring us immersive feel, most of the traditional virtual reality systems use desktop virtual reality mode, which lack of sense immersion, interaction is poor, and can＇t let the experiencer immersed in the virtual system. According to these factors, this paper based on the requirements of three-dimensional virtual campus system simulation, designed and implemented the immersive virtual campus walkthrough system based on Unity3D platform, researched the key technologies of immersive virtual campus development. Experimen- tal results show that this system can overcome the shortcoming of insufficient immersion during virtual roaming, users can experience the realis- tic virtual environment similar to a real campus, and can interact with the virtual environment. This system is simple and easy to implement, has broad application prospects
