Abstract

The system and method for fusing infrared images and low-light images provided by the present invention perform side suppression enhancement processing on infrared images and low-light images to obtain IR images and LLL images, perform preprocessing on IR images to obtain partial images T, and combine LLL images and T image is weighted and calculated, LLL′ image is obtained, LLL′ image is processed, +LLL′ image is obtained, IR image is processed, ‑IR image is obtained, ‑IR image enters the surrounding area of ​​ON module, +LLL′ image Enter the central area of ​​the ON module to obtain the fused image. The present invention uses the bionic biological vision ON-OFF model to input the infrared image through the OFF system and the low-light image through the ON system into the inhibition area and excited area of ​​the ON system respectively. area, so as to obtain a fused image that conforms to human vision, has clear targets, and has rich background details.

Description

technical field [0001] The invention belongs to the field of image technology, and particularly relates to a system and method for fusion of infrared images and low-light images. Background technique [0002] Because infrared images are images produced by the radiation of the object itself, it can "actively" obtain target information in the scene, and can display hidden thermal targets well, and is less affected by lighting conditions and bad weather, but at the same time due to Due to the limitation of the imaging principle, the infrared image has low contrast, strong spatial correlation, and poor ability to reflect the details of the target, and the imaging effect does not conform to the visual habits of the human eye. [0003] Low-light images belong to the category of visible light, especially under low illumination, their content information is richer than that of infrared images, which can better describe the details of the environment, but limited by the environment a...
