摘　　要：为了提高系统的监控能力降低成本,提出了一种基于CMOS的多通道视频监控方案。首先基于同步信号控制各路视频同步,保证图像质量。在此基础上由DSP和FPGA产生控制切换信号,控制多路视频切换,从而实现了一个监控系统同时对不同场景的精密监控。使用QuartusII 8.1和Visaul DSP++等软件,经过反复的调试和实验,该方案在视频监控告警系统中成功实现对多路视频的控制。In order to improve monitoring capabilities of the system and reduce costs,a CMOS-based multi-channel video surveillance program was designed.First,the system based on synchronization signals control video images from various quarters synchronous to ensure image quality.On this basis,the switching signals which generated by the DSP and the FPGA controls multiple video switching,so by one monitoring system could achieve the same precision control for different scenarios.After observing and analyzing,debugging and repeated experiments with Quartus II 8.1,Visaul DSP＋＋ and other softwares in video monitoring,the program successfully achieved multi-channel video controlling in the alarm system.
