基于OpenGL的飞行场景红外仿真

在现代化战争中,红外探测与制导技术的使用已越来越广泛,因此如何实时生成战场环境的红外图像就变得非常重要。在Visual C++6.0环境中,利用OpenGL构建了可见光飞行场景;主要基于红外辐射相关理论,对场景中的目标和背景模型进行了红外辐射特性分析,并计算出了各部分模型面元的红外辐射强度;同时使用LOWTRAN7软件分析了大气衰减的影响,并通过灰度量化和OpenGL渲染技术构建了一种实时、动态的飞行场景红外仿真系统。试验结果表明,该系统能够实时生成飞行目标在不同红外波段及不同大气环境影响下的红外图像。

Infrared Simulation of Flying Scene Based on OpenGL

Since infrared detection and guidance technologies are more widely used in the modern war, how to generate the infrared images of battlefield environment in real time becomes very important. A visible flying scene is constructed by using Visual C 6.0 and OpenGL. The infrared radiation characteristics of the target and background models in the scene are analyzed mainly on the basis of the theory about infrared radiation. The infrared radiation intensity of each part of the models is calculated. At the same time, the effect of atmospheric attenuation is analyzed by using LOWTRAN7 and a real-time dynamic infrared flying scene simulation system is constructed through grey level quantization and OpenGL's rendering. The experimental result shows that the system can generate the infrared images of flying targets in different infrared wavebands in different atmospheric environment.
