红外成像仿真的关键环节在于红外图像的生成,飞机目标的红外图像生成是重要的研究内容,具有重大的军事意义和经济意义。基于理论分析和计算机技术提出了飞机目标红外图像生成的方法,根据红外物理学、空气动力学以及传热学等基本理论,建立飞机目标的红外理论模型,计算出蒙皮、尾喷管和羽烟等重点辐射区域的温度场和辐射场,利用灰度等级描述红外辐射信息,经过建模、视点变换、环境设置等一系列处理并渲染生成红外图像。实验结果证明,红外图像生成方法可行,结果可信。
The key part of infrared imaging simulation is the generation of infrared images. The generation of infrared images of aircraft targets is an important research content, which has great military and economic significance. Based on theoretical analysis and computer technology, a method for generating infrared images of aircraft targets is proposed. According to the basic theories of infrared physics, aerodynamics and heat transfer, the infrared theoretical models of aircraft targets are established. The skin, tail pipe and plume Smoke and other key radiation areas of the temperature field and the radiation field, the use of gray-scale infrared radiation information, through modeling, viewpoint transformation, environmental settings and a series of rendering and rendering infrared images. Experimental results show that the infrared image generation method is feasible and the result is credible.
