Problems solved by technology

However, compared with visible light images, the background stray light of the ship target image in the infrared scene has a greater impact and cannot reflect the accurate sea and sky background and the radiation characteristics of the ship target itself. Therefore, it is necessary to enhance the details of the ship target image in the infrared scene.
[0003] At present, the commonly used infrared image enhancement technology can be based on the histogram enhancement technology (Global Histogram Equalization, GHE), but the GHE method will break the phenomenon of oversaturation after the pixel with a large gray value in the original image is enhanced.

Abstract

The invention relates to an infrared image processing method and device, a computer device and a storage medium, and relates to the technical field of image processing. The infrared image processing method comprises the following steps: acquiring a to-be-processed initial infrared image, and segmenting the initial infrared image into a plurality of sub-interval images; splicing the sub-interval images to form a plurality of sub-images with different semantic tags; and performing gray scale enhancement on each sub-image, and performing linear weighted superposition on each enhanced sub-image toobtain an output infrared image. According to the invention, the occurrence of a grey degree supersaturation phenomenon can be avoided.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an infrared image processing method, device, computer equipment and storage medium. Background technique [0002] Due to its high environmental adaptability, passive imaging and other advantages, infrared imaging technology has been more and more used in various fields, especially in the monitoring and rescue of ships on the sea surface. However, compared with visible light images, the background stray light of the ship target image in the infrared scene has a greater influence and cannot reflect the accurate sea and sky background and the radiation characteristics of the ship target itself. Therefore, it is necessary to enhance the details of the ship target image in the infrared scene. [0003] At present, the commonly used infrared image enhancement technology can be based on the histogram enhancement technology (Global Histogram Equalization, GHE), but the GHE method...
