摘　　要：设计了一种基于DVI接口的高速图像采集控制系统。该系统能够稳定采集Camlink接口的高速CCD传输的数字信号,并能提供一路DVI接口高清显示和一路PAL制式复合视频。系统可与上位机通过CAN总线实现数据交互,并提供数字视频信号给压缩存储单元和图像处理单元。系统硬件结构简单,工作稳定可靠,能够广泛应用于图像处理领域。A high-speed image acquisition and control system based on DVI interface is designed. The system stably acquires digital sig nals transmitted by high-speed CCD of Camlink interface, and provides one high-definition display with DVI interface and one PAL for- mat composite video. The system exchanges data with host computer through CAN bus and provides digital video signal for compres sion/storage unit and image processing unit. The system has simple hardware structure,good stablity and reliability. It can be widely ap plied to image processing field.
