摘要

红外成像仿真的关键环节在于红外图像的生成,云的红外图像生成是重要的研究内容,具有重大的军事意义。基于分形技术提出了云的红外图像生成的技术方法,综合考虑云红外辐射的各个因素,建立了较为完善的云的红外辐射模型,基于光学厚度计算出云的辐射亮度。建立分形高度到云光学厚度、云的辐射亮度到图像灰度的两个映射,利用分形技术实现云红外图像生成。经过与实测数据和实拍图像比较,云的红外图像生成方法可行。

Abstract

IR Scene simulation is an important way for design and assessment of IR missile, and the key of simulation is the generation of IR scene image, and the research of infrared image generation of cloud is an important topic. A method of generating IR images of cloud based on fractal technology was proposed. The infrared model of cloud was constructed based on physics analysis, and the irradiance of cloud can be computed according to optical thickness. To simulate infrared image of cloud, irradiances of cloud were mapped to gray levels and the fractal height was mapped to optical thickness, and cloud was generated by fractal method. Compared with actual measurements and infrared images, the method of generating infrared image of cloud is applicable, and the result is credible.

Key words： cloud; IR image; computer image generation; fractal
