Visible Light And Infrared Image Acquisition And Fusion Technology Research

Multi-source image fusion is primarily an image domain within the range ofinformation fusion research， it is mainly aimed at a variety of images，the main purpose ofthe fusion is to improve the reliability of redundant image data by data processing between aplurality of images. By processing the complementary information between the plurality ofimages to improve image clarity. In recent years, image fusion has become an important anduseful new technologies in he field of image understanding and computer vision. In order toobtain the infrared and visible light dual-band images，it must rely on a completetly set ofhigh-speed image acquisition and processing system. Most of the current image acquisitionsystem via a computer interface to transfer data to computer, with the high speed and largememory capacity of the computer to completely capture the image. USB interface has fewersystem resources, easy to expand and easly been used, make it more and more important inthe image acquisition system occupies.In this context, this paper presents the image acquisition and processing system based inUSB2.0interface, combined the requirements of the system,it is achieved the high-speedreal-time display of image. In this paper, it used the CY7C68013A driver chip toaccomplished the USB2.0protocol.the speed of transmission meets the requirements, and thesystem has no dropped frames. Using programmable logic device to accomplish the timingdrive control, sequential circuits and firmware design procedures. Achieved the two-waydata communications and system is reliability and stability. Using a pixel-level imagefusion scheme and a quantitative parameter to analysis the fused image. Achieve theintegration between infrared and visible images using surface interpolation scheme, andenhanced image fusion and processing, Designd a variety of pseudo-color transformation,the fusion image is clear and easy to identify, meets the system requirements.
