针对传统多路视频监控系统控制不灵活、处理速度慢、系统无法对各路视频信号进行视频算法等问题,介绍了一种采用FPGA设计多路视频实时处理和显示的系统方案.通过使用单片FPGA硬件方式实现多路视频的采集、格式转化、视频缓存、视频算法处理、视频拼接和显示,并可以进行多路视频与其中任意一路视频切换显示和处理,同时系统支持对每一路视频进行不同的算法处理.该方案利用FPGA的并行处理能力,可以实时处理和显示4路视频,帧频达到了15帧/s,每一路视频信号的处理时间不超过4 ms.该方案具有低成本、低功耗、实时性好、扩展性强等特点,适用于目前常用的视频监控应用场景.
Aiming at the problems that the traditional multi-channel video surveillance system is inflexible, the processing speed is slow and the system can not carry out the video algorithm for each video signal, a system scheme of real-time processing and display of multi-channel video by FPGA is introduced. FPGA hardware way to achieve multi-channel video capture, format conversion, video caching, video algorithm processing, video splicing and display, and can be multi-channel video and any one of the video switch display and processing, while the system supports each video is different The program uses FPGA parallel processing capabilities, real-time processing and display 4 video, frame rate reached 15 frames / s, each video signal processing time does not exceed 4 ms. The program has low cost, low Power consumption, real-time, scalability and other characteristics suitable for the current common video surveillance applications.
