红外遥控摄像存储仪的设计及实现
摘要
随着图像数据处理技术和嵌入式技术的快速发展,以及实验室等科研单位安防意识的不断提高,专门为实验室研究一款红外遥控摄像存储仪已经成为必然趋势。该课题以设计一种廉价、实用、体积小和功耗低的视频监控系统为目的,采用了以ARM9架构为内核的微处理器SC32440作为硬件控制的核心,以嵌入式Linux操作系统为软件架构的核心,并将通用的USB摄像头作为前端视频采集设备,完成了红外遥控摄像存储仪的设计。
本文首先介绍了视频监控系统的发展历史,介绍了嵌入式操作系统的概念及特点。接着进行了系统设计的介绍。该系统釆用基于客户端/服务器的架构,以ARMS3C2440嵌入式开发板为服务器端,以监控主机(PC)作为客户端。服务器端首先利用Video4Linux接口实现USB摄像头的图像采集;,以减少数据流量和带宽的占用;接着将图像数据采用基于TCP/IP协议的socket编程完成了在主机和开发板之间的传输。,以实现实时的远程监控。
本文的主要设计开发工作包括:为系统构建平台,其中涉及U-Boot移植、Linux内核移植和根文件系统构建;实现图像数据的采集、编码、传输;实现了QT用户图形界面的设计;实现客户端对图像数据的接收、解码、显示。测试表明本文设计的红外遥控摄像存储仪实现了实时视频监控的基本功能,在功耗、体积、实时性、可移动性和扩展性等方面有明显优势,具有良好的应用前景。

Design and Realization of infrared remote control camera storage apparatus
Abstract
With the image data processing technology and the rapid development of embedded technology, as well as laboratories and other research institutions to continuously improve security awareness, specifically for the infrared remote imaging laboratory studies a storage device has e an inevitable trend. The subject in order to design a cheap, practical, small size and low power consumption for the purpose of video surveillance systems, using the ARM9 architecture for the kernel to SC32440 microprocessor as the core hardware control to embedded Linux operating system as the software architecture core, and the generic USB camera video capture device as a front end plete the infrared remote camera storage device design.
This paper describes the history of the development of video surveillance systems, introduced the concept of embedded operating system and features. Then the system design introduction. Preclude the use of the system based on client / server architecture to ARMS3C2440 embedded development board for the server side, in order to monitor the host (PC) as a client. First, the use of server-side Vid
