Multi-channel Embedded Video Monitoring System Based on TMS320DM642

Abstract

近年来,随着社会物质水平的不断提高,人们对安全防范和现场记录报警系统的需求越来越大,要求也越来越高,从而促进了视频监控系统的普及和快速发展。目前市场的视频监控系统多以图像采集卡采集图像,并借助于微机系统的高速运算能力和大容量存储器来完成对视频图像的实时压缩和存储等。这类系统能够即压即存,但同时带来体积大、成本高、工作稳定性差和感兴趣内容检索麻烦等不足。 随着视频监控系统的快速普及,市场划分也越来越细,传统的视频监控系统覆盖所有应用,性价比不高。本文针对场景变化不是很频繁的监控场合(家庭监控、重要仪器设备监控、野生动物调查监控等领域),设计、开发了一款嵌入式多路视频监控记录系统。该视频监控系统...Recently, with the constant improvement of social material living standards, the demand for security and on-site alarm system grows rapidly and the requirements are getting higher, it improves the popularity and rapid development of video monitoring system. Nowadays, video monitoring system on the market often uses image acquisition card to acquire image, and it relies on computer system’s high-sp...学位:工学硕士院系专业:信息科学与技术学院通信工程系_信号与信息处理学号:2332006115262
