USB imaging devices with the IMAQdx driver

[ashish saraf]

Hello everyone,

I am new user to LabView,

I want to acquire image from USB camera , for that I have installed imaq_USB_installer.. Will it is possible with IMAQdx driver also ?

Can I compare and distinguish images through USB camera after processing ?

Thank you.

Ashish,

You don't want to use the imaq_usb installer. It is outdated and was never supported by NI. All the functionality has been superseded by functionality in IMAQdx (part of Vision Acquisition). It should work if your camera provides DirectShow drivers. You can download the latest Vision Acquisition (2010.8 as of this post) to try it out here:

If you want to do any processing on images besides simply viewing/saving, you want Vision Development Module. You can try out the 2010 version here:

Thank you for solution.....

I made this vi (attached) but it is showing error, i dont know what it is ?

I want to distinguish two images i.e (i want to do Face recognition . ) Can i compare two images in a rough manner directly as in attached vi...

Can i have any example vi for study as per my requirement i.e based on face recognition...

Thank You once again

you cannot enter pathnames into the imaq-image.

Before you can start with operations,

you have to create an imaq image using IMAQ_Create

and then fill this image using IMAQ_Readfile
