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。
In view of the existing video monitoring system has low performance, poor flexibility, inconvenience updating, high development cost, 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 to realize the video signal processing, and finally displayed on the VGA moni- tor. Compared with other video monitoring equipment, the system can achieve efficient video monitoring, and has high real--time perform- ance, low cost, high reliability.
