摘要
随着人们对图像质量的要求越来越高,图像数据量大幅增加,传统的数据传输接口在一定程度上难以满足图像数据快速传输的需求,因此需要传输效率更快、性能更稳定的图像采集传输系统。利用千兆以太网高速稳定的传输特性,ZYNQ-7000全可编程系统ARM+FPGA的组合架构,设计了一款基于GigE Vision的高速图像采集传输系统,实现了图像数据的格式转换、存储和传输,最后通过RGMII接口输出到上位机,并且利用GigE Vision协议的通信方式接收上位机发出的指令,根据指令内容控制摄像头工作。经测试,系统实现了上位机对摄像头的控制功能,图像数据的传输功能,传输速率达到980Mbps,满足高速数据传输的要求且稳定可靠。
As people's requirements for image quality are getting higher and higher,the amount of image data has increased significantly,and traditional data transmission interfaces are difficult to meet the needs of fast image data transmission to a certain extent.Therefore,image acquisition with faster transmission efficiency and more stable performance is required.Transmission sys⁃tem.Using the high-speed and stable transmission characteristics of Gigabit Ethernet and the combined architecture of ZYNQ-7000 fully programmable system ARM+FPGA,a high-speed image acquisition and transmission system based on GigE Vision is de⁃signed,which realizes the format conversion,storage and transmission of image data,and finally transmitted to the host computer through the RGMII interface.This system uses the communication mode of GigE Vision protocol to receive the instructions sent by the host computer,and controls the camera to work according to the content of the instructions.After testing,the system has real⁃ized the control function of the host computer to the camera,the transmission function of image data,and the transmission rate reaches 980Mbps,which meets the requirements of high-speed data transmission and is stable and reliable.
