Infrared image multi-scale stripe noise removing method and system and storage medium

The invention relates to the technical field of image processing, in particular to an infrared image multi-scale stripe noise removing method and system and a storage medium. Comprising the following steps: performing N-time down-sampling on a first infrared image to obtain the first infrared image; performing one-dimensional unilateral gray filtering 1 * n on the first infrared image in a first direction to obtain a low-frequency first infrared image, and filtering the low-frequency first infrared image to obtain a stripe amplitude of the high-frequency first infrared image in a second direction; performing up-sampling on the stripe amplitude of the high-frequency first infrared image in the second direction to obtain the stripe amplitude of the original width of the first infrared image; and subtracting the stripe amplitude of the original width of the corresponding position of the first infrared image from the pixel points in the first direction of the first infrared image to obtain the first infrared imag
