Embodiment 1

[0066] A preferred embodiment of the present invention provides a method for restoring the resolution of an infrared polarized super-pixel radiation intensity image, such as figure 1 shown, including the following steps:

[0067] Step 1: Obtain the pixel data of any two sets of polarization angles that are orthogonal to each other, and preprocess them to obtain the M×N order polarization data matrix O(M, N), and obtain the polarization data matrix O(M, N) ) to get the polarization intensity data In this embodiment, values ​​of any two groups of polarization angles that are orthogonal to each other are specifically 0, 45, 90, and 135. The specific method of this step is as follows:

[0068] Step 1-1: Read the pixel data of four different polarization angles collected by the uncooled infrared focal plane micro-polarization array detector, which is the original infrared intensity data of the image size M×N obtained by the focal plane pixel , and perform image two-point corr...

Description

technical field [0001] The invention relates to the field of infrared image processing, in particular to a method for restoring the resolution of an infrared polarization super-pixel radiation intensity image. Background technique [0002] Infrared polarization imaging technology uses the polarization information generated by objects in the process of emitting, scattering, reflecting and transmitting electromagnetic waves for imaging. Different objects or different states of the same object (such as roughness, water content, physical and chemical characteristics of materials, etc.) Infrared bands tend to have different polarization states. This technology can well distinguish targets and backgrounds with the same thermal radiation but different polarization characteristics, and can effectively reveal the shape structure, texture, roughness and other characteristics of the target surface. [0003] The commonly used technical means for infrared polarization detection include ...
