摘　　要：针对全景多目标侦察遥感图像传输速度慢、传输质量差等问题,采用GTX高速串行收发技术、大容量高速缓存技术,设计了一种基于现场可编程门阵列(FPGA)的全景图像采集与高速传输系统,主要包括图像采集模块、GTX图像传输模块、数据缓存模块以及图像显示模块。GTX图像传输模块选用光纤作为传输介质,SFP+作为传输接口,传输协议为Aurora 8B10B single lane 4 byte,数据缓存模块选用DDR3 SDRAM作为系统的高速缓存单元。实验测试结果表明,系统最高可采集图像分辨率为500×10^(4)pixels,最高可实现10.3125 Gbps高速视频图像的光纤无失真传输,误码率约为10^(-12),为大容量图像采集和传输提供了一种可行的方案。For the problems of slow transmission speed and poor transmission quality of panoramic multi-target reconnaissance remote sensing images,a panoramic image acquisition and high-speed transmission system based on FPGA is designed by using GTX high-speed serial transceiver technology,mainly including image acquisition module,GTX image transmission module,data cache module and image display module.The GTX image transmission module uses optical fiber as the transmission medium,SFP+as the transmission interface,and the transmission protocol is Aurora 8B1B single lane 4 byte,the data cache module uses DDR3 SDRAM as the cache unit of the system.Experimental test results show that the system can capture images with a maximum resolution of 500×10^(4)pixels,and can achieve up to 10.3125 Gbps high-speed video image transmission without distortion over optical fibre,with a BER of about 10^(-12),providing a feasible solution for high-capacity image capture and transmission.
