摘要
数字视频监控系统以其直观、方便、信息内容丰富的特点越来越受到人们的重视,已成为安全防范系统的重要组成部分。视频采集子系统主要完成视频图像的采集和压缩,是数字化视频监控中最核心的部分,直接影响着整个监控系统性能和质量的好坏。针对新一代的视频监控系统对视频图像的质量和实时性的要求,本文设计出一种基于DSP和PCI接口的视频采集卡。
Digital video surveillance system with its characteristics of intuitive, convenient, content-rich information, has become an important component of the security system. The subsystems of video capture video images achieve the collection and compression of digital video surveillance, which are the most core part of a digital video surveillance system. For the quality and real-time requirements from the video surveillance system of a new generation to video image, the paper designs a video capture card based on DSP and PCI interface.
