摘 要 分布式系统的应用极其广泛，特别是应用在大型工业现场设备的管理，以及各种各样的监控场所。在分布式系统中，设备硬件的设计和研发，以及设备之间的通信和数据传输，关系到整个系统功能和性能。将嵌入式技术应用到分布式系统的设计当中，利用嵌入式设备体积小、成本和功耗低、性能好等优点，来实现分布式系统的功能和提高其性能，具有很好的市场应用前景。数字图像处理作为一门崭新的学科，发展十分迅速，并且已经在科学研究、工农业生产、军事技术、医疗卫生等领域发挥着越来越重要的作用。因此，本文在分布式系统的基础上利用嵌入式技术构建了一套基于嵌入式的分布式图像处理系统。本文主要工作是完成了整个硬件平台的设计和软件的初步设计。 在硬件方面，区别于传统的在 Windows 系统下采用数据采集卡进行数据采集的方式，使用USB摄像头和基于ARM9核的S3C2410A处理器组成图像采集装置，并设计了网卡电路模块，用于将图像数据通过以太网传输到宿主机。 在软件方面，实现了Bootloader、嵌入式Linux内核和根文件系统的移植，实现了USB主机控制器驱动和USB设备类驱动在目标板上的移植，并设计了基于图像数据的采集、网络传输和显示的应用软件。 最后，本文对整个系统的调试进行了总结，并记录了相关实验结果。结果表明本系统运行稳定，其硬件平台可以作为基础平台研究数字图像处理等领域的应用，也可适用于更为广泛的分布式系统其它应用方面的研究。 关键词： ARM；Linux；嵌入式系统；TCP；图像处理 Research and Development of Distributed Image Processing System Based on ARM9 Abstract The application of distributed systems is extremely broad, especially used for devices management in large-scale industrial field, as well as a variety of monitoring sites. In distributed systems, design and development of hardware as well as communications and data transmission on devices have an impact on the functions and performance of the entire system. Embedded technology will be applied to the design of distributed systems, and due to advantages of small size, low cost and power consumption, high performance and so on which embedded devices have, we can realize the functions of distributed systems and improve their performance with good market prospect. Digital image processing as a new subject are developing rapidly and playing an increasingly important role in scientific research, industrial and agricultural production, military technology, health and other fields. Therefore, this paper sets up an embedded distributed image processing system based on distributed system by using of embedded technology. The major work is to complete the design of the entire hardware platform and preliminary design of the software. In terms of hardware, different from the way using data acquisition card in Windows system conventionally, we use USB camera and S3C
