Abstract

The invention discloses a low-visibility approach flight multi-modal monitoring image enhancement method, and belongs to the technical field of multi-modal image enhancement processing. According to the method, an infrared thermal imaging image is enhanced based on MSRCR, and a visible light image is enhanced based on a multi-exposure image fusion method; then registering the enhanced image by adopting a multi-modal image automatic registration method based on a contour feature main direction; and finally, fusion processing is carried out based on a multi-modal image fusion method of an image pyramid, and infrared information and visible light information are registered and fused into one image, so that feature information complementation is realized, redundant information is reduced, and the monitoring field of view of a pilot under the condition of low-visibility approaching flight is enhanced.

Description

technical field [0001] The invention relates to the technical field of multimodal image enhancement processing, in particular to a multimodal surveillance image enhancement method for low visibility approach flight. Background technique [0002] The aircraft approach and landing stage is an important part of safe flight. In this stage, most of the time, the landing depends on the captain's visual situation, so there are great potential safety hazards. This stage is also the easy point of flight accidents. If it can provide the captain with a real and effective flight situation and view out of the window during the aircraft approach and landing phase, and enhance the pilot's vision, it can help the captain to perform correct perception and operation, and reduce the incidence of flight accidents during the aircraft approach and landing phase. In order to solve this problem, advanced photoelectric sensors such as infrared thermal imaging and visible light are used to obtain sce...
