摘要
针对高空飞艇在飞行控制半物理仿真实验中实时数据可视化的问题,基于虚拟仿真技术,提出了一种高空飞艇视景仿真系统设计方案。建立了高空飞艇三维模型,并使用细节层次等高级建模技术对三维模型数据库进行了优化。提出了通过反射内存网与半物理仿真系统进行实时数据传输的方式,在Vega Prime环境下完成了基于控制台的视景仿真程序开发。在硬件系统支持下,实现了高空飞艇飞行过程仿真场景的立体渲染,仿真效果能够满足半物理仿真实验数据的实时逼真显示要求。
Focused on the real-time data visualization problem of high altitude airship （HAA） in the flight control semi-physical simulation experiment, a HAA scene simulation system was proposed based on virtual simulation technology. The HAA three-dimension （3-D） model was established whose database was optimized by using advanced modeling techniques such as level of detail （LOD）. The data gain from the semi-physical simulation was transmitted through reflective memory net; and the scene simulation application was developed in Vega Prime environment. The 3-D scene for HAA flight progress is drawn by the hardware system, the simulation result is able to show the real-time data of semi-physical simulation experiment realistically.
