trigger for two camera simutanously

[Wiltchs]

Hi there,

how i trigger two camera simultanously to capture images in the same time exactly?

i use frame grabber NI CVS-1457RT , two cameras (GigE vision) on realtime.

i've found an example vi "HL Grab with two boards.vi" but its not compatible with the cvs.

another question, where can i find a tutorials about  cvs an FPGA to acquire an image?

i am using LabVIEW 2015, LabVIEW FPGA and Realtime.

thank you

HI there!

Google gives you plenty of results 🙂

Triggering:

You also can do it in LV using property node.

NI propose also a new Vision course since 2014 if I remember well, let's have a look at it. 

Hope that is helping you.

With many cameras you can send a software trigger so that they acquire at approximately the same time. Or are you trying to use a hardware trigger?
