摘要
虚拟场景建模是虚拟现实技术中的关键技术之一。为了更真实有效地模拟飞机在机场飞行区运动过程中的特殊视景,在简化模型的基础上,使用实例技术、外部引用和LOD技术几何建模,并进一步举例说明物理建模和运动建模的过程,给出了仿真实现的详细流程。该方法能够使管制员在雷达屏幕上观察飞机的动态及一些特殊情况,并及时解决冲突。利用Creator、Vega及Visual C++6.0,实现了对机场飞行区特殊视景的仿真。结果表明该系统在培训管制员方面起到了很重要的作用,从而减少了特殊事件对飞机产生的影响及在地面的碰撞事故,缓解了管制员的压力。
The virtual scene modeling is one of the key technologies of virtual reality technology. In order to more effectively simulate the special scene of the plane flighting in the aircraft movement area, based on the simplified model, geometric modeling is conducted using case technology, external reference technology and LOD technology. The paper then illustrates the process of physical modeling and movement modeling to achieve a detailed description of the simulation process. This method enables air traffic controllers to observe the states of the aircraft and some special cases through the radar screen, and give a timely solution to con- flicts. The special scene simulation system uses Creator,Vega and Visual C ＋ ＋6.0. The result shows that this system has played a very important role in training controllers, reducing the impact of special events on the aircraft and the crashes of the aircraft on the ~round and eases the oressure of the cnntrollers.
