红外偏振成像技术是利用物体偏振度上的差异来对复杂背景下的目标进行探测的。 在战场上, 由于人造物体和自然景物在偏振度上存在差异, 红外偏振成像技术能够提高人们对自然景物及伪装的辨别 能力。首先介绍了偏振成像理论及其系统的结构组成, 然后对基于偏振图像处理的目标特征提取 过程进行了分析, 并对偏振图像像质评价方法以及图像融合、分割和特征提取方法进行了研究。最后给 出了国外基于偏振成像目标检测技术的应用研究情况, 并指出了该技术在**领域中的应用价值。

Infrared polarization imaging can use the difference of objects in the degree of polarization to detect the targets against the complex background. In the battlefield, because the man-made and natural objects have a difference in the degree of polarization, the use of infrared polarization imaging can improve one’s ability to distinguish the camouflage from the nature. Firstly, the theory of polarization imaging and its system components are presented. Then, the target feature extraction based on the polarization image processing is analyzed. The polarization image quality evaluation, image fusion, image segmentation and feature extraction methods are studied. Finally, the applications based on infrared polarization imaging at abroad are given and the value of this technology to military applications is pointed out.
