摘　　要：在深入分析双色中波红外被动热成像过程的基础上,明确了双色中波红外成像的影响因素,建立了点目标的双色中波红外图像的形成模型,并对模型进行了仿真实验,揭示了双色中波红外点目标成像特性差异的形成机理,明确了双色中波红外点目标成像在灰度值、目标受环境影响和目标背景对比度等三个方面存在的差异,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,为双色中波图像特征提取、融合规则和融合权重确定等提供了依据。On the basis of analyzing the process of passive thermal imaging in dual-color mid-wave infrared, we proposed the dual-color mid-wave infrared imaging of influencing factors, set up forming model of point target imaging in dual-color mid-wave infrared and simulated experiment, revealed the formation mechanism of differences of point target imaging characteristics in dual-color mid-wave infrared, discovered point target imaging with three differences in dual-color mid-wave infrared, which are gray value, environmental effects and target background contrasts of images. Differences in image features of the experiment proved the existence of these different imaging characteristics generally. It provides the basis for extracting the image feature, selecting of the fusion rule and weight coefficient in dual-color mid-wave infrared image process.
