Infrared image multi-dimensional noise reduction method, storage medium and infrared image multi-dimensional noise reduction device

The invention discloses an infrared image multi-dimensional noise reduction method and device and a storage medium, and relates to the technical field of infrared image processing. The method comprises the following steps: preprocessing an infrared image acquired by an infrared detector to obtain an original image; dividing an original image into a background layer and a detail layer through guide filtering; for the background layer, compressing the background layer by using a dynamic compression method; for the detail layer, further performing multi-dimensional layering based on an equivalence relation concept in a rough set theory to obtain a low-noise sub-graph, an uncertain-noise sub-graph and a high-noise sub-graph, respectively determining an enhancement coefficient, a self-adaptive noise reduction coefficient and a noise reduction coefficient, multiplying the coefficients by the sub-graphs to obtain a new sub-graph, and combining to obtain a new detail layer; and finally, combining the background layer
