Abstract

The invention discloses an image fusion system based on Cameralink and an image fusion method based on Cameralink. The image fusion system comprises two paths of Cameralink vudei receiving systems, an FPGA, a memory, a multinucleated DSP and a display, wherein the two paths of Cameralink vudei receiving systems are respectively connected with the FPGA, and the FPGA is respectively connected with the memory, the multinucleated DSP and the display. According to the image fusion system, fused two-path video inputs are respectively Cameralink, transmission band width can reach above Gpbs, the image fusion system has a substantial advantage in high-resolution high-frame frequency image processing; a data TTL signal generated when a Cameralink camera signal passes through a video receiving system decoding difference module has simple time sequence, the two videos have quite small phase difference at one time, two paths of images are fused for realization in the FPGA.

Description

technical field [0001] The invention belongs to the technical field of high-speed image acquisition, in particular to an image fusion system and method based on Cameralink. Background technique [0002] Image fusion is an important branch and research hotspot of information fusion. Image fusion is an advanced image processing technology that combines multiple images of the same scene obtained from sensors with different characteristics, different times, and different resolutions into one image. Image fusion technology has been widely used in many fields, including remote sensing image analysis and processing, automatic recognition, computer vision, medical image processing, etc. The fused image has strong robustness, and even individual sensor failures will not have a serious impact on the fused image; image fusion can cooperate with multiple sensor image information of the same scene to output a picture that is more suitable for human visual perception or computer further ...
