空天一体化视景仿真关键技术研究

Research on Key Technologies of Scene Simulation About Aerospace Integration

针对空天场景中仿真实体坐标系难以组织,通过研究空天场景坐标系的一般关系树,提出基于Vega Prim e的坐标系关系树组织结构;通过设计观察目标到视点距离和视域远近裁减面的函数对应关系,解决了空天场景中由于实体尺寸差别悬殊带来的展现失真问题;对气象环境加入区域约束,根据视点位置确定当前气象环境效果,实现空天场景多环境的展现.设计KTSG系统,实现了空天一体化场景的逼真显示.

A novel organizational structure of coordinates＇ hierarchical tree that base on Vega Prime was proposed, aiming at organizing the simulation entities in aerospace. A novel function was designed, which is composed of the distance between target and observer, the near clipping plane, and the far clipping plane. Successfully prevent the problem of display distortion. The multi-environments were displayed in aerospace scene, building on adding region restrict to meteorological environment. Current meteorological environment was chose according to the position of viewer. KTSG system was designed, exactly displaying the space scene.
