基于ARM的嵌入式视频监控终端的研究
|
摘要
随着工业技术的不断发展,以及人对安全防范意识的逐渐加强,视频监控系统已经成为人们在生产、生活中必不可少的一个部分。特别是近年来,随着计算机技术的发展、宽带的普及、图像处理技术的提高,视频监控在越来越广泛地渗透到教育、娱乐、医疗、运动等各个领域。视频监测系统已经成为当今可视化领域的一个新的开发热点。许多应用领域对于视频监控系统提出了更高更新的要求,如何经济有效地实现特定环境所需的监控功能,给我们提出了新的课题。
本文设计和实现了基于ARM9和Linux操作系统的嵌入式视频监控系统,实现视频图像的采集、压缩和传输。文章结合嵌入式技术、图像压缩技术和网络技术,设计了一种基于嵌入式的网络视频监控系统。
本文首先研究了视频监控系统的发展现状及今后发展趋势,详细分析了嵌入式监控系统的基本原理和性能要求,提出了系统的设计的总体方案。在硬件设计方面,系统采用三星公司的S3C2410A作为嵌入式处理器,配合外围硬件电路构成嵌入式核心板。系统采用模块化设计方案,将硬件划分为三大模块:主控器与储存器模块;电源时钟复位电路模块;外围接口电路模块。在论文中对各个部分进行了详细的介绍。完成了核心板的硬件设计后,接下来介绍如何构建嵌入式监控系统的软件平台,包括成功的移植Linux操作系统;嵌入式Linux下USB接口摄像头驱动的接口和实现。最后在基于嵌入式Linux系统的平台上完成应用程序的设计,完成视频图像的采集、压缩、传输,这部分主要完成的工作有:如何使用Video4Linux API库函数实现图像采集;如何实现视频流的软件压缩;如何保证视频流数据的实时传输。
本文实现了一种体积小、成本低廉、数字化的监控解决方案。该系统可满足监控系统对数据传输可靠性和实时性的要求,具有广泛的应用价值。
With unceasing development of industrial technology and the people's sense of safety precaution gradual strengthening,video Surveillance System has become an indispensable part of people in production and daily life. Especially in recent years, with the development of computer technology, broadband penetration and the improvement of image processing technology, video surveillance is becoming more and more widely infiltrated into education, entertainment, medical care and sports fields. Video monitoring system has become a new hot spot in the visual field. Many application fields for the video surveillance system is facing higher and newer requirement. So how to achieve monitoring function economically and efficiently in specific environment,it gives us a new research subject.
The thesis aims at finding a feasible method to realize the video Surveillance which based in ARM and Linux. It realize video image capturing,compression and transmission. In this article,we integrate embedded technology, image compression and network technology to design a network video monitoring system based on embedded.
This article has first researched the present situation and the next trend of development of video Surveillance System. We analyse basic principle and performance requirement of embedded surveillance system and put forward a overall blue print. In the hardware design,we adopts Samsung S3C2410A as embedded processors, cooperating the periphery hardware circuit to constitute the embedded core board. The design of system uses the modularization proposal. Hardware will be divided into three modules: the processors and memory modules;the power, the clock and the restart circuit module;the periphery interface circuit module. We has detailed introducd each part in the paper. After completing hardware design of core board,we introduced how constructs the software platform of the embedded supervisory system,including how to successful transplant Linux operating system, how to develop a low layer driver to run the USB camera. Finally,we completes the application programme in this platform which is based on the embedded Linux system.The application programme realize video image capturing,compression and transmission. In this part, We discuss how to use the Video for Linux interface to capturing video stream,how to achieve sofeware cmpression of video streaming and how to ensure Real-Time transmission.
This paper introduces a small size, low cost, digital monitoring solution. Practice has proved that the system can satisfy the demands for reliability and real-time requirements. This system can be used in a lot of situation and has a great marking potential.
