摘　　要：为了在工业现场和安防监控领域更好地利用Hi3559强大的视频图像处理能力实现高清视频的远距离传输和智能算法,采用Hi3559+FPGA硬件架构,通过高清数字接口(High Definition Digital Interface,HD-SDI)视频均衡器利用同轴线缆传输方式,设计实现了多路1080P的高清视频传输系统。该设计系统方案主要是解决了Hi3559虽然支持多种Sensor视频接口,但是没有可以直接支持多路HD-SDI摄像头的输入方式和设计方案。该系统利用Hi3559实现了8路HD-SDI视频图像的采集、传输、处理、以及全景显示。相比海思常见的相机串行接口(Camera Serial Interface,CSI)传输方案,采用HD-SDI传输距离更远,理论可达200 m。通过测试和验证,该设计方案可行,传输距离远,工作稳定可靠,对于多路HD-SDI视频的采集传输和全景显示等方向具有较高的推广和应用价值。In order to make better use of Hi3559′s powerful video image processing capabilities in the field of industrial sites and security monitoring,to achieve long-distance transmission of high-definition video and intelligent algorithms,adopting Hi3559+FPGA hardware architecture,using the coaxial cable transmission method with the high-definition digital interface(HD-SDI)video equalizer,this paper designs and realizes the multi-channel 1080P high-definition video transmission system.This design system solution mainly solves that although Hi3559 supports a variety of Sensor video interfaces,it does not have an input method and design solution that can directly support multiple HD-SDI cameras.The system uses Hi3559 to realize 8-channel HD-SDI video image acquisition,transmission,processing and panoramic display.Compared with HiSilicon′s common camera serial interface(Camera Serial Interface,CSI)interface transmission scheme,HD-SDI transmission distance is farther theoretically up to 200 m.Through testing and verification,the design scheme is feasible,long transmission distance,stable and reliable,and has high promotion and application value for the acquisition and transmission of multi-channel HD-SDI video and panoramic display.
