【摘要】：图像融合技术是在图像处理技术领域中比较关键和热门的技术,无论是在民用还是军用领域都有着广泛的应用。TMS320DM8168作为德州仪器公司(Texas Instruments,TI)推出的最新一代的一款高性能达芬奇系列芯片,在视频图像处理领域应用广泛。本文以TMS320DM8168芯片为核心处理器,对嵌入式图像融合系统平台的技术做了深入研究。本文首先对图像融合技术、TI公司的达芬奇技术及其发展状况作了介绍,对融合系统常采用的硬件平台作出对比,结合本融合系统总体目标需求和达芬奇技术的优势完成了图像融合系统平台的方案设计,还对核心处理器TMS320DM8168功能结构以及性能参数进行了研究。然后,根据系统方案要求,研制了基于TMS320DM8168芯片的图像处理板,主要包括图像处理板上的主要接口及资源设计,重点分析了图像处理板的核心电路及视频输入输出电路的设计。最后,对系统的开发环境进行了深入研究,包括平台构成、环境搭建以及 DVRRDK(Digital Video Recorder Research DevelopmentKit)软件框架,尤其是Link节点以及其内部结构。通过构建Link链路形成多通道视频处理框架(Multi Channel FrameWork Software,McFW),并将算法Link集成到主程序链,实现视频的采集、处理及显示功能,并对图像融合算法进行了研究和移植,将算法移植到TMS320DM8168图像处理板上,实现了不同算法对视频图像的处理。通过对算法处理的结果进行了分析,验证本融合系统平台的可行性。
[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.
