摘要
高清视频技术已日渐成为视频监控的重要发展方向。随着我国高速公路建设的快速发展,高速公路视频监控系统经历了"全模拟视频监控—准数字监控系统—纯数字监控系统"的发展历程,现在已发展为以"高清"为特征的视频监控系统。以贵州省某条高速公路的高清视频监控系统为例,对视频标准及其选用原则,视频信号编码、传输和存储等进行阐述,并对高清视频技术在高速公路监控系统中的应用进行探讨。
High- definition technology has been increasingly becoming important development direction of video surveillance. With rapid development of China expressway construction, the expressway video surveillance systems experienced the development history of ＂ full analog video surveillance- quasi- digital surveillance system- pure digital surveillance system＂,and now have developed into the video surveillance system with ＂ high- definition＂ as the feature. With the high- definition video surveillance system of some expressway in Guizhou Province as an example,this paper expatiates video standards and principles of selection,coding,transmission and storage of video signals,etc.,and discusses application of high-definition video technology in expressway surveillance systems.
