摘要
红外成像仿真已成为红外成像制导武器设计和评估的重要方法,具有重大的军事和经济意义。仿真的关键环节在于红外图像的生成。提出了基于分形技术的天空背景红外图像生成的技术方法,综合考虑海洋战场环境下天空背景辐射的各个因素,对晴空条件下的天空辐射分量进行了分析计算,并根据视点建立了云的红外辐射模型,计算出云的各个辐射分量,得到天空及云的红外辐射亮度。将天空及云的辐射亮度量化为灰度等级,并利用分形技术实现天空红外图像生成。天空背景的红外图像生成方法可行,结果可信。
IR scene simulation is an important way for designing and assessing the IR guided missile, and the key of simulation is the generation of IR scene image. A method of generating sky background IR images based on fractal technology is proposed. The infrared models of sky and clouds are constructed based on physics analysis. The irradiance of sky background can be computed according to the viewpoint. To simulate infrared image of sky and clouds,Jrradiances of sky and clouds are mapped to gray levels, and clouds are generated with fractal method. This method of generating sky infrared image is applicable, and the results prove to be reliable.
