Infrared polarization image fusion method of uncooled infrared focal plane array

The invention discloses an infrared polarization image fusion method for an uncooled infrared focal plane array, and the method comprises the steps: reading original data of the uncooled infrared focal plane array, carrying out the processing, and carrying out the filtering and other preprocessing of the processed data; calculating the preprocessed pixel data to obtain a polarization parameter; performing high-low frequency decomposition on the obtained polarization parameters to obtain a low-frequency image and a high-frequency detail image; obtaining a to-be-fused low-frequency image based on the obtained polarization parameter and the low-frequency image; based on the high-frequency detail image, obtaining a to-be-fused high-frequency image; and carrying out reverse reconstruction on the low-frequency image to be fused and the high-frequency image to be fused to obtain a fused image. According to the invention, different polarization information reflected by radiation such as the material and the texture o
