视频监控系统原理与设计

Video Surveillance System Theory and Design

数字视频监控系统的核心就是数字视频采集和处理.数字视频处理的过程分为视频图像输入、视频信号处理、编码.视频图像输入由摄像头扫描光信号转变为电信号(标准信号、非标准信号).视频信号处理主要有计算机系统配合视频采集卡来完成,处理好的信号以数字方式进行编码和储存,也可以进行数模转换后显示输出.

The core digital video surveillance system is digital video capture and processing.The process is divided into digital video processing video input,video signal processing,coding.Video image input from the camera scanning optical signals into electrical signals（standard signal,non-standard signals）.There are video signal processing computer systems with video capture card to complete the deal a good signal is digitally encoded and stored,it can display the output after digital-analog conversion.
