飞机红外图像生成研究

摘要

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。%IR Scene simulation is an important way to design and assess the IR missile,and the key of simulation is the generation of IR scene image, and the research of infrared image generation of airplane is an important topic. A method of generating IR images of airplane is proposed. The infrared model of airplane is built based on infrared physics and aerodynamics, and temperature distribution and radiant intensity of skin, nozzle and plume are computed. Radiance can be converted to gray value, and infrared images are generated after a series of processing. The simulation result shows that the method of generating infrared image of airplane is applicable, and the result is credible.
