【摘要】 地面红外场景模拟是利用数字图像分析方法和计算机图形学技术,结合地面背景的红外辐射特性数据,合成地面红外场景的图像。其研究具有重要的理论意义和广泛的应用前景。 本文采用多谱段图像分析法和随机场模型法,生成了典型地物的红外纹理图像,并利用多谱段图像法和地图构造模型法,合成了静态地面红外场景图像。利用计算机仿射技术对二维静态场景图像进行三维变换,并根据探测视场的变化,实现了三维地面场景的模拟。同时采用图像数据库技术实现了动态场景模拟。 建立红外纹理灰度与红外辐射场的函数映射关系,从而生成红外纹理图像,其方法具有一定的创新性;图像数据库技术的引入,为动态场景仿真提供了新的研究思路。

【Abstract】 Infrared ground scene modeling deals with the synthesis of infrared ground images, in which digital image analysis and computer graphics are employed and the data of infrared radiance characters are combined. It is one of important researches in the field of computer simulation and widely used in arms test, infrared missile guiding and proving the performance of infrared detector.In this paper the method of the multi-spectral image analysis (MSI A) and random field models are introduced to synthesize infrared texture images. And MSIA and map construction model are adopted to generate static infrared images of ground scenes. With the technology of computer projection three-dimension (3D) ground scene images are obtained from the static ones. And the generation of 3D scenes is fulfilled according to the variation of the field of view of the detector. The image database is introduced to generate dynamic ground scenes.The adopted method of infrared texture images generation is a novel one, which builds up the relationship between the gray levels of texture images and the infrared radiance fields. The technique of image database provides us a new idea of dynamic scene generation.
