Embodiment Construction

[0030] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0031] The degree of polarization corresponding to the target under different detection wavelengths and radiation temperatures is not a fixed constant, and changes with the radiation wavelength and radiation temperature. In the prior art, when determining the degree of polarization of the target, the linear polarization image is generally synthesized directly based on the infrared thermal polarization images using four linear polarization directions according to the arithmetic weighting method. Since there is no unified reference, it is impossible to intuitively understand the physical meaning of the degree of polarization value, let alone understand the change of the degree of polarization value...

Abstract

Disclosed is an infrared polarization image quantitative processing method comprises the steps of determining the degree of polarization of a target according to the radiation brightness of the target in different directions of rotation, determining the degree of polarization of a black body according to the radiation brightness of the black body in different directions of rotation, and determining the relative degree of polarization of the target based on the degree of polarization of the target and the degree of polarization of the black body and by taking the degree of polarization of the black body as a benchmark. According to the invention, the relative degree of polarization of the target is determined by choosing a reference benchmark, and the value of polarization of the target and the change in degree of polarization under different conditions can be known visually. As the value of polarization of the black body in different bands and radiation temperature ranges is stable, the accuracy of the quantitative processing result can be improved by choosing the black body as a reference benchmark.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a quantitative processing method of an infrared polarization image. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The analysis and calculation method of the polarization characteristics of infrared radiation is to use the infrared thermal polarization images of four linear polarization directions, and directly synthesize the linear polarization degree image according to the arithmetic weighting method. The infrared polarization degree p is a dimensionless number within [0, 1]. Although the linear polarization degree is often expressed as a ratio, the infrared polarization degree of the target surface is not a fixed value under different radiation temperatures or radiation wavelengths. In order to ...
