摘要
该文设计了一种基于千兆以太网络的视频采集与传输系统,主要由摄像头视频采集模块,FPGA模块,cotex-A8模块和NetFPGA模块4部分组成。前端摄像头模块将实时采集回的视频图像分为两路,一路传输给FPGA模块之后,通过VGA进行本地实时显示,另一路通过cotex-A8模块将图像由WIFI网络上传至主服务器进行显示与保存,之后通过NetFPGA模块将主服务器的视频进行多路分发,可实现多用户节点同时对主服务器进行高速访问。
This paper introduces a video capture and transmission system based on Gigabit Ethernet,consisting of camera video capture module,FPGA module,Cotex-A8 module and NetFPGA module.The real-time video image which collected by the front camera module,will be divided into two roads,one is transmitted to FPGA module and local real-time displayed through VGA,the other through cotex-A8 module will be uploaded to the master server to display and save through WIFI.Then,the video stored in the master server will be multi-channel distributed by the NetFPGA module.It could realize multi-user node high-speed access to the host at the same time.
