【摘要】 数字图像处理技术近年来得到了极大的重视和长足的发展,在通讯、管理、医学、地震、气象、航空航天以及教育等领域发挥着愈来愈重要的作用。但是面向应用的图像处理系统却不尽如人意,不能很好的满足图像应用的要求。传统基于PC机的图像处理系统体积庞大,不具有便携性;桌面操作系统不具有实时性。传统的图像处理实现方法越来越不能满足图像应用实时性和小型化的要求。对此,本文探索一种基于ARM嵌入式平台的图像处理解决方案。本文研究基于嵌入式系统架构的图像处理系统的设计与实现方法。嵌入式系统具有体积小、性能好、功耗低、可靠性高等突出特征,可以满足日益复杂的图像应用要求。本文针对嵌入式系统的特点,设计出具有较强通用性的嵌入式图像处理平台。它方便与其它系统组合安装,形成集图像采集处理一体化的应用系统。这样的系统经扩展后可以应用到各种领域中。本系统由硬件和软件两部分组成。硬件部分采用由广州致远电子有限公司开发的MagicARM2410开发平台,并根据系统的功能需求对其硬件资源进行裁剪。软件部分使用Platform Builder 5.0集成开发环境来定制满足要求的Windows CE 5.0操作系统,并通过FlashFXP软件的控制将内核镜像文件烧写到开发平台的Flash中。图像算法部分使用eMbedded Visual C++ 4.0开发应用程序,实现图像的灰度化、直方图、边缘检测、轮廓提取等常用功能。本系统经过测试运行稳定,可以很好的完成图像处理操作。达到系统设计目标的要求。更多还原

【Abstract】 The digital image processing technology has got great attention and considerable development in recent years. It plays a more and more important role in communication, management, medicine, seismology, meteorology, aerospace, education and other fields. However, the image processing system that faces application is not satisfactory, and can’t well respond to the request of image application. The traditional image processing system based on PC is too bulky to have portability; the desk-top operating system does not have real-time character. The traditional realization method of image processing can’t meet the demand more and more in real-time and miniaturization of image application. In this regard, this paper explores a solution of image processing system based on ARM embedded platform.This paper studies the design and implementation method of image processing system which based on embedded system architecture. Embedded system has a small size, good performance, low power, high reliability and other prominent feature. It can meet the increasingly complex image applications require. This text aims at the characteristic of embedded system to design an embedded image processing platform which has stronger universal. It is convenient to combine and install with other systems, forming an integrative application system with image collecting and processing. This system can be applied to a variety of areas after expanding.This system is made up of hardware and software. The hardware part adopts MagicARM2410 developing platform which developed by Guangzhou Zhiyuan electronics Co., Ltd. And cut out its hardware resources according to the system function demands. The software part uses Platform Builder 5.0 integrated development environment to customize Windows CE 5.0 operating system which can meet system demands, and writes the kernel image file into Flash of developing platform through the control of FlashFXP software. The image algorithm part uses eMbedded Visual C++ 4.0 to develop application program, realize grey, histogram, edge detecting, profile extraction and other common functions.This system runs stable through testing, and can well complete image processing operation.更多还原
