摘　　要：利用现成的多媒体视频卡商品，在分析其工作原理的基础上，解决了控制视频帧／场采样的启动与结束及所采集视频数据从卡上的读取，实现了实时图像数据的采集，可应用于要求利用视觉信息构造闭环反馈的智能控制系统中。How to use an off-the-shelf multimedia vedio card to realize real-time digital image acquisition is introduced.The principle of the video card is analyzed, and give methods to how to start and stop video frame/field acquisition and how to read and process data fiom the video card. The card can be used to acquire image in real-time, and especially can be used to the intelligen close-loop control systems which need visual information for feedback.
