摘　　要：视景仿真作为无人机飞行模拟的一部分,实现了飞行场景的可视化。针对无人机三维可视化过程中的若干关键技术进行研究,如飞机尾焰生成、真实地形渲染、天空建模、镜头光晕绘制等。最后借助VC++和OpenGL编程工具,在普通PC机上实现了飞行视景的三维可视化,达到了较高的帧频率和逼真的动画效果,满足飞行场景实时显示的要求,具有一定的工程应用价值。The simulation of flight scene as part of the UAV flight simulation,realizes the visualization of the flight scene.During the process of realizing UAV＇s 3D virtual simulation,some key technologies was emphasized,such as generation of tail flame,rendering of terrain,modeling of sky,drawing of lens flare and so on.Finally,the flight scene simulation was realized on the ordinary PC platforms by using VC＋＋ and OpenGL programming technology.The result achieved a high FPS and a vivid animation effect.It satisfied the requirement of the real-time display.This achievement has some certain values in engineering applications.
