摘要
针对安防监控与智慧交通领域无盲区视频摄录的需求,基于Zynq-7000平台优势进行宽幅视频处理软硬件系统的设计。通过研究基于嵌入式系统的多路视频实时拼接技术,设计并实现了以XC7Z020芯片为核心的视频处理板卡,在双核ARM Cotex-A9硬核处理器端服务程序协同调度下,基于片内FPGA硬件加速能力实现多通道视频实时采集与预处理、投影变换、图像融合,进而形成完整宽幅视频画面,通过远程客户端实现定制化的视频摄录功能。测试结果表明,该系统是兼具稳定的性能和灵活区域部署能力的便携式解决方案。
For the requirements of no blind-zone video recording in security monitoring and intelligent transportation area, the paper design a wide-field vision video processing system based on Zynq-7000 platform. Through the research of multi-channel real-time video mosaic technology based on embedded system, it design and implements video processing board, which is centered on the XC7Z020 chip, with co-scheduling service program running on Dual ARM Cotex-A9 processor,and video capture and pre-processing,projection transformation, image blending IP sub-system running on FPGA, and the customized video play function is realizeed through remote client. The experiment shows that the system is a portable solution both with stable performance and flexible area deployment.
