目前国内红外偏振成像技术的研究尚处于初步的实验阶段,需要开展具有针对性的红外偏振成像实验,以支撑红外偏振成像理论和技术的研究。基于高灵敏度的中波制冷焦平面探测器,搭建了中波红外偏振成像系统,并针对特定场景中的典型目标,开展了红外偏振成像实验,获得了有效的实验数据和成像规律,并基于HSV颜色空间对偏振信息图像进行了融合再现实验研究。结果表明:中波偏振热成像可突出光滑表面的轮廓及金属与水泥构件等的差异,有利于对隐藏目标和伪装目标的探测与识别;利用彩色图像融合方法融合热辐射强度、偏振度和偏振角图像是一种可行的偏振图像再现方式,能够综合反映偏振热成像的有效信息。
At present, the research on infrared polarization imaging technology in China is still at the preliminary experimental stage, and a targeted infrared polarization imaging experiment needs to be carried out to support the research on the theory and technology of infrared polarization imaging. Based on the highly sensitive mid-wave cooled focal plane detector, a mid-wave infrared polarization imaging system is set up and infrared polarization imaging experiments are carried out for typical targets in specific scenes. Experimental data and imaging rules are obtained. Based on HSV Color Space Polarization Information Images Fusion Experimental Research. The results show that the thermal imaging can highlight the difference between the smooth surface and the metal and the cement components, which is beneficial to the detection and recognition of hidden targets and camouflage targets. The fusion of thermal radiation intensity, polarization degree and polarization Angle image is a feasible method of polarization image reproduction, which can reflect the effective information of polarization thermal imaging.
