摘要
基于长波红外偏振成像探测技术在目标检测识别领域的优势,本文搭建了长波红外偏振成像探测系统,采集了室内外典型目标的长波红外偏振图像,提取了三类典型目标的斯托克斯矢量、偏振度、偏振角以及两个组合特征δ与ρ等图像信息,并对其特点进行了详细分析。基于对图像偏振信息的解算,提出了一种目标背景对比度增强方法。实验证明该方法可行且有效。
On the basis of advantages of Long Wave Infrared (LWIR) polarization imaging in the field of target detection and recognition, a LWIR polarization imaging detection system is built. The LWIR polarization images of some typical indoor and outdoor objects are collected by the system. The image information of three kinds of targets, such as Stokes vectors (I, Q, U), degree of linear polarization, angle of polarization and two combined features δ and ρ, is extracted. Their characteristics are analyzed in detail. A new method for enhancing target-background contrast based on the infrared polarization information obtained is proposed. The experimental result shows that the method is feasible and effective.
