[Abstract]:Image fusion is a key and popular technology in the field of image processing. TMS320DM8168 has been widely used in both civil and military fields as the latest generation of high performance Da Vinci series chips released by Texas Instruments Company (Texas Instruments,TI). It is widely used in the field of video image processing. Based on TMS320DM8168 chip, the technology of embedded image fusion system platform is studied in this paper. In this paper, the image fusion technology and its development of TI Company are introduced, and the hardware platform used in the fusion system is compared. The scheme design of the image fusion system platform is completed based on the overall target requirements of the fusion system and the advantages of Leonardo da Vinci technology. The functional structure and performance parameters of the core processor TMS320DM8168 are also studied. Then, according to the requirements of the system, the image processing board based on TMS320DM8168 chip is developed, which mainly includes the main interface and resource design on the image processing board. The design of the core circuit and the video input and output circuit of the image processing board are analyzed. Finally, the development environment of the system is deeply studied, including platform construction, environment construction and DVRRDK (Digital Video Recorder Research DevelopmentKit) software framework, especially the Link node and its internal structure. By constructing the Link link to form a multi-channel video processing framework (Multi Channel FrameWork Software,McFW), the algorithm Link is integrated into the main program chain to realize the functions of video acquisition, processing and display, and the image fusion algorithm is studied and transplanted. The algorithm is transplanted to the TMS320DM8168 image processing board, and the video image processing is realized by different algorithms. The results of the algorithm processing are analyzed to verify the feasibility of the fusion system platform.
