Abstract

To solve the problem that target recognition in infrared detection blindness, a DoFP infrared polarimetric imagery is designed. The top of the infrared detector pixel, based on a domestically made uncooled long-wave infrared focal plane array detector, integrates a micro-polarizer array with different polarization directions. Then, according to the infrared intensity image, infrared DoLP image, and infrared AoP image of the infrared blind spot scene, which have different physical properties and imaging characteristics, a multi-polarization parameter infrared polarization fusion method is integrated at the information processing end of the detector, and the fusion criterion of polarization color mapping is adopted. The test results show that the system can output the infrared intensity, DoLP, AoP and infrared polarization fusion enhanced image of the target scene in real time, and can effectively detect the target in the infrared blind area. The study has great potential for camouflage recognition and polarization remote sensing.
