vision builder AI 可以用USB相机并使用外部触发吗

刚刚接触NI的产品,下载了VBAI的评估版,觉得使用非常方便。但碰到一个问题,使用USB相机如何使用外部触发呢?请别笑话,我是用笔记本自带的摄像头测试的。我觉得外部触发通过serial I/O给电脑一个信号,然后电脑采集相机的图象,再作分析检测,应该可以实现。可是找来找去找不到这方面的资料,太困惑了。

Most advanced functions of USB cameras are not supported in Vision Builder or LabVIEW.

 

Triggering is one of those advanced functions.

 

Your only option might be to run the camera at maximum speed, and grab the image closest to your trigger point.
