Thermal infrared image quantification and adaptive enhancement method and system, and storage medium

The invention provides a thermal infrared image quantification and adaptive enhancement method and system and a storage medium, and the method comprises the steps: S1, adjusting an input 14-bit thermal infrared image to different brightness through employing the Gama transformation of different parameters, and carrying out the normalization, and obtaining images of different brightness levels; s2, respectively processing the images with different brightness by adopting a filtering-based enhancement method to obtain a base layer and a detail layer of the image, and re-combining the enhanced detail layer with the base layer to obtain an enhancement result under each brightness; s3, fusing the plurality of images under different brightness levels after being enhanced in the step S1 and the step S2, so that detail features under different brightness levels are all reserved in one image; and S4, quantifying the 14-bit thermal infrared image into an 8-bit thermal infrared image to obtain a final image.
