基于双色中波红外被动热探测过程,分两个阶段建立了面目标的双色中波红外图像形成模型,并对模型进行了仿真实验,得到了双色中波红外面目标图像在灰度值、目标受背景影响和目标背景对比度等3个方面存在的差异,通过实验图像的差异特征验证了这些成像特性差异存在的普遍性,为双色中波红外图像特征提取、融合规则和融合权重确定等提供了理论依据。
Based on the process of dual-color MWIR passive thermal detection,we set up forming model of surface target imaging in dual-color MWIR by dividing the process in two stages and simulated experiment,and discovered surface target imaging.With three differences(gray value,environmental effects and target background contrasts of images) in dual-color MWIR.Differences in image features of the experiment proved the existence of these different imaging characteristics generally.It provides the basis for extracting of image feature,selecting of fusion rule and weight coefficient in dual-color mid-wave infrared image process.
