Abstract: 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.

Key words: computer application, binocular vision, Gigabit Ethernet, external trigger, synchronous acquisition
