Acquire Images from webcam in LabVIEW 8.5

[Dejay]

I've been working with Labview for week now and have done several online tutorials and things like that. I need to be able to record an image from a webcam into Labview. I've found numerous discussions on the topic but none that contain any solid examples. I have Labview 8.5 with the NI-IMAQ drivers and NI Vision.

What are the basic steps that need to be done to aquire an image from a webcam and display it on a front panel? Any example VI's or detailed descriptions would be more than welcome. Please understand that I have just started working with LabView so some concepts like device drivers are still a little new to me. Thank you for any help you can provide.

Hi Dejay,

You are not clear of which webcam u are using.

If u are using an USB cam

this would definitely help u.

What about in labview 8.5? there is no IMAQ folder?

Hello CanadianKyle

 U can download ni_imaq_usb_installer_86.exe from ni.com website so u can get IMAQ Files in your LabVIEW 8.5.

It loads the IMAQ files in your labView so that u can use them to acquire images from that inbuilt VIs.

Best Luck........

Is there anyway to use this without having Vision 7.1? (quite an expensive add-on!)

Hi CanadianKyle,

I've been working with Labview for few months now and have done several online tutorials and things like that.

but i can not tell you exactly that Vision requirement is must or not?......

But I Think there is no other way to use this without Vision 7.1 or Higher.

U will get Vision with evaluation version on Ni.com.

You can try for this, It will help you.

best luck.
