Description

technical field [0001] The invention relates to an image processing system, in particular to a real-time fusion system of an infrared image and a low-illuminance image, belonging to the technical field of digital image processing. Background technique [0002] Night vision technology has not only become an indispensable modern equipment for the army, but also has a wide range of applications in all walks of life. In recent years, with the localization and price drop of uncooled infrared detectors, the civilian infrared night vision market has entered a period of rapid growth. [0003] Night vision technology includes infrared night vision technology and low-light night vision technology. Thermal imaging technology in infrared night vision is a passive infrared night vision technology, which realizes observation by using the infrared radiation emitted by the target itself. It detects the target according to the temperature difference or thermal radiation difference between t...
