摘　　要：该系统以FPGA为逻辑控制单元,充分利用模块化结构设计、乒乓无缝缓存和Two-plane页编程FLASH的存储技术,利用视频解码芯片对高速CCD相机采集的图像信息进行解码,实现了高速图像数据的采集存储,保证了数据在采集、传输和存储过程中的可靠性和实时性。通过USB2.0接口将存储的数据上传到地面计算机,利用上位机软件可以清晰看到拍摄的物体。结果表明:该系统能准确采集存储高速图像数据,具有较好的可行性和实用性。This system, which takes the field programmable gate array （FPGA） as logic control unit, sufficiently adopts modularization design,pingpong seamless cache memory and Two-plane page program Flash storage technology, and acquire image data which decoding by video decode chip from high speed CCD camera. The design accomplishes the capture and storage of high speed image ,and it insures the reliability and real-time property of the image data during acquiring, transferring and storing them. This system could read and get these image data from Flash by USB2.0 port and will be stored information uploaded to the ground computer and display clear video or picture by the computer software. The results show that this acquisition and storage system could get exact image data and it provideds with preferable feasibility and practicability.
