摘　　要：设计了一种遥感相机图像传输系统,用于接收并解码光学遥感系统的数据。该系统以FPGA作为逻辑控制的核心,以CameraLink接口作为与上位机数据传输的接口。描述了系统的主要组成和FPGA模块化设计的实现方法,阐述了系统的基本硬件结构和软件工作流程,并给出了其核心模块的时序仿真波形图。测试结果表明本系统数传速率达到6.72Gbps,能实现遥感相机图像数据的实时解码传输,满足系统设计要求。A camera images transferring system is introduced in this paper for decoding data from remote sensing cameras. The system uses FPGA as the core logic control and uses CameraLink as the interface of data transmission with the host computer. The main component of the system and the implementation method of FPGA are described and the simulation waveforms of main modules are also presented. Test results show that the design achieves data transfer speed 6.72 Gbps,realizing camera images decoding,and meets the system requirement.
