基于FPGA的多路视频监控系统设计

Design of Multi Channel Video Monitoring System Based on FPGA

为了能在同一时间从多角度对某处场景进行实时视频监控,利用FPGA设计一种可实现多通道同频显示的监控系统.采用四路模拟摄像头采集监控视频数据,经四通道视频解码芯片TW2867模数转换后输入FPGA进行数据处理,再经过数模转换芯片ADV7123在VGA显示器上实现四路同屏显示,以达到实时监控的目的.

In order to realize real-time video monitoring from the multiple angles of scene at the same time,a kind of monitoring system was designed, which can display several channels under the same frequency through the FPGA.Four channels analog camera to capture video data,4-channel video de- coders TW2867 were used to convert the analog signal to digital signal hefore putting it to FPGA to handle the data,and then used the D/A chip ADVT123 was used to convert the digital signal to analog signal,and finally the 4-channel video signal on the same screen on the VGA can be displayed to achieve the purpose of real-time monitoring.
