红外瞄准镜图像灰度不均匀问题分析研究

Research on Inhomogeneous Image Grayscale Problem Analysis of Infrared Sight

文章介绍了非制冷型红外热成像系统的工作原理,分析了红外瞄准镜图像灰度不均匀问题的几种影响因素。通过一种基于常数统计约束的校正算法,在一定程度能够解决红外瞄准镜在环境条件剧烈变化下的图像灰度不均匀问题,为后期红外瞄准镜的工程研制及试验鉴定工作提供了一定的理论支撑。

In this paper,the working principle of uncooled infrared thermal imaging system is introduced,and several influencing factors of the inhomogeneous image grayscale problem of infrared sight are analyzed.The problem of inhomogeneous image grayscale of infrared sight under the drastic change of environmental conditions is solved to a certain extent through a correction algorithm based on constant statistics constraints,which provides a certain theoretical support for the later engineering development and test and evaluation of infrared sight.
