Abstract

The invention relates to a fusion processing of a high-definition image. The circuit comprises a core processor, and a video input module, a video output module, a power supply module, a clock module and a memory module which are connected with the core processor. The video input module comprises two paths of Camralink port chips and is used for decoding Camralink data and transmitting decoded data to the core processor. The core processor is used for achieving receiving, image scaling, character superposition, image translation, image storage and an image fusion algorithm for real-time video image data, and achieving real-time video image data. The video output module is used for carrying out VGA output for the real-time video image data generated by the core processor. According to the invention, fusion of high-resolution real-time digital images is achieved; the processing speed is quicker and the data processing quantity is bigger than a simulation video image fusion processing circuit; and the resolution of the fused image is high.

Description

technical field [0001] The invention relates to a high-resolution image fusion processing circuit, which belongs to the technical field of image processing. Background technique [0002] Visible light images are reflective images with many high-frequency components, which can reflect the details of the scene under a certain illumination; infrared images are radiation images, and the grayscale is determined by the temperature difference between the target and the background, which cannot reflect the real scene. There are deficiencies in using visible light images or infrared images alone. For these two complementary images, image fusion technology can effectively synthesize and explore their feature information, enhance scene understanding, and highlight targets, which is conducive to hiding and camouflaging. Detect targets faster and more accurately in both ambiguous and confusing situations. With the development of the fusion technology of visible light image and infrared ...
