| 摘 要： | 针对现有的视频监控系统具有性能低,灵活性差,不便更新,开发成本高,可靠性低的问题,设计了一种基于现场可编程门阵列FPGA的视频监控系统。该系统首先利用CMOS摄像头OV7670获取模拟视频图像,双端口SDRAM对图像数据进行缓存,然后利用FPGA对视频信号处理能力强,集成度高,灵活性强,并行处理等特点实现对视频信号的处理,进而达到最终在VGA显示器上显示的效果。与其他视频监控设备相比,该系统能够高效的实现视频监控,而且具有实时性高,成本低,可靠性强等优点。

| Abstract: | In view of the existing video monitoring system has low performance, poor flexibility, inconvenience updating, high development cost, the problem of low reliability, we design a video monitoring system based on field programmable gate array FPGA. First the system receive the analog video image by using CMOS camera OV7670 and storage this data by the dual-port SDRAM, utilize video signal processing ability, high level of integration, strong flexibility, parallel processing and any other characteristics of FPGA to realize the video signal processing, and finally displayed on the VGA monitor. Compared with other video monitoring equipment, the system can achieve efficient video monitoring, and has high real-time performance, low cost, high reliability and any other advantages. |
