Hi, my name is Luis (medel) and i'm doing a project with a robot to realize stereovision, and i have the same troubles that you guys. I use 2 USB webcams but everytime i try to see both images labvoew crash, the only thing that i see that stops this is when you use an STATUS property linked to the GO button like the examples of the PETES home page with the webcam. You must use two STATUS property to prevent crash linked to an AND gate and then to the GO button inside the WHILE process.
That's one idea to STOP crashing Labview, also i have an idea to see the two images, why not open a sesion1 first grab a image1 then close the sesion1, open sesion 2 grab image2 and close sesion2 all this inside a WHILE process, it sounds complicated but why don't give it a try? one posible problem it's that the images could be a little "slow"
