基于Creator和Vega的红外飞行视景仿真

目前,红外飞行视景仿真已成为飞行仿真的一个重要研究方向,具有重大的军事和经济意义.针对视景仿真技术对于在夜视条件下也可以进行飞行仿真的问题,文中提出利用Creator建立三维地形模型;基于Vega仿真软件环境开发天空、地面背景和飞机效果;利用Vega中的SensorVision模块讨论了红外飞行视景生成技术,模拟在夜视条件下红外飞行视景环境,以及观察到的红外景象;利用C 编程,调用Vega API函数,开发了视景仿真程序,最后基于MFC完成了对于红外飞行视景仿真的软件界面的开发.开发和应用结果表明,该系统灵活通用,比基于OpenGL图形库开发的红外视景仿真提高了画面逼真度,缩短了开发周期.

IR Flight Scene Simulation Based on Creator and Vega

The IR flight scene simulation is an important research direction of the flight simulation and it is worthful in military and economy.In order to solve the problem of flight simulation at night,a 3D models is created using Creator.The sky and ground background and airplane are generated based on Vega software environment,and the creating of the IR flight scene simulation using SensorVision is discussed.The scene simulation program is written in C by calling the Vega API functions.The software interface of IR flight scene based on MFC is introduced.The results of development and application show that the system is flexible,the efficiency of development and the reality of 3D image are improved as compared with the scene simulation software simulation software based on OpenGL.
