image processing with imaq vision with 2 webcams on the same computer

[bleung]

Hi,

I'm currently trying to set up 2 usb webcams (logitech quickcam for notebooks pro). I want to be able to have them both run simultaneously and do some image processing with the images that I get from both cameras with labview and imaq vision.

As of right now, I'm having trouble getting both cameras to run at the same time. Any help would be gladly appreciated. Thanks.

The USB IMAQ driver will not support running 2 USB cameras at a time (I believe it is a limitation of the DirectShow interface). You could open one camera, acuqire an image, close the reference to that camera and then do the same for the second camera.

If you need simultaneous acquisition, look at possibly moving to 1394 cameras or analog cameras.
