View Full Version : LabVIEW: Acquire triggered images from 2 Cameras

May 5, 2006, 06:27:17
I have configured two Imaging Control Objects in my Labview code. One for DMK21BF04 and one for DFK31BF03. Both are configured for acquiring images on external trigger. The trigger source is different for both of them. I have two different while loops running for acquiring images from these two cameras.

DFK31BF03 is triggered thrice in one cycle. The trigger interval (72ms) of the three images is just over the device frame rate (15fps). With the while loop of the other camera is deactivated, I am able to acquire these three frames in each cycle consistently.

DMK21BF04 is triggered once in each cycle after the three triggers to the DFK31BF03. When both the while loops are active, I am expecting the DFK31BF03 to return 3 frames and DMK21BF04 to return 1 frame at the end of the cycle. Instead I see only one frame from DFK31BF03 and one from DMK21BF04.

Can anybody guess what could be the problem?

It would be a great help if you could send a sample vi to support@imagingcontrol.com.
