摘　　要：基于千兆以太网实现了连接在同一台计算机上的两部相机同时工作。采用一个即插即用的数据采集模块作为同步触发信号发生器,利用LabVIEW编程产生两路具有指定周期的同步脉冲信号,用于触发两部相机同步工作。采用Microsoft Visual C++编写相机同步采集软件,实现了两台相机间的同步图像采集及自动存储。同步帧率达到18帧/s,为课题组的双目视觉脉搏信息测量研究奠定了基础。On the basis of Gigabit Ethernet,two cameras connected to the same computer can work simultaneously.A plug and play data acquisition module was adopted as a synchronous signal generator.By means of LabVIEW programming,two synchronous pulse signals with a specified period were generated,which were then used to trigger two cameras.Microsoft Visual C＋ ＋ was used to develop the synchronous acquisition software. The two cameras can capture images synchronously and the images can be automatically saved.The maximum synchronous frame rate is up to 18 frames per second,laying a good foundation for the research of binocular vision pulse information measurement.
