摘要
为了加快惯性导航系统的开发,设计了一种基于虚拟现实的惯导试验系统,用于捷联惯性导航系统设计及测试。详细介绍了系统的结构及功能组成,探讨了系统的虚拟现实建模方法和视景生成过程。并为系统建立了基于真实地形信息的三维地形,利用虚拟现实工具软件Vega完成了系统的视景仿真。结果表明该系统能使研究人员直观地考察导航过程、船体姿态,且画面逼真、流畅,为舰载捷联惯性导航系统的快速开发及算法的研究提供了有力的工具。
To accelerate the development of inertial navigation system, a navigation testing system based on virtual reality is designed for the aid of research. The structure and fuctions are introduced in detail, the method and process of vitual reality modeling and visual simulation are discussed. A real data based 3D terrain is established, and the visual simulation is accomplished with Vega. The results show that the process of navigation and ship attitude can be observed directly in truth, and the system will be a utility tool for the research of strap-down inertial navigation system.
