基于OpenGL的舰船目标红外图像生成

文中基于OpenGL对舰船目标进行红外热像模拟，根据红外物理和传热学知识。综合考虑面元之间辐射、传导、对流以及面元与周围大气、海面、太阳之间的辐射、对流，建立较为完善的舰船目标红外物理模型，计算出舰船各部分的温度分布及辐射亮度分布。根据辐射亮度量化为灰度信息，经过建模、视点变换、环境设置等一系列处理并渲染输出红外图像，并利用双缓存技术实现动态红外图像的生成。

IR Image Generation of Warship Based on OpenGL

Based on OpenGL, the simulation method of warship is proposed. The full infrared model of warship is built based on infrared physics and heat transfer, which includes the radiation, convection, conduction between different parts of the warship, and which also includes the radiation, convection of environment. After radiance of warship computed, radiance could be converted to gray value. After a series of processing, the dynamic IR images are generated with the technology of double buffered.
