Hi sherok,

what have you done so far? There exits an USB driver for IMAQ. Do you want to use Vision for your project?

Hi sherok,

You will need the Vision Development module, Vision Acquisition, and LabVIEW of course. After you will need to download this driver: NI-IMAQ for USB cameras.

Do you have all of those things?

Also, the NI-IMAQ for USB cameras is not technically supported by NI. It's provided as-is as an extra, but no guarantees if anything goes wrong.

Info on Object Classification.

There's also a link on that page to the evaluation version of the software.

Yet I have grab the image but I don't understand what should I do further.........If there is any example code available or manual so I could read that or even is any one can explain me that how can I do object classification using USB camera......

Well, once you have the image, it's back to basics time!

I highly recommend the NI Vision Concepts Manual. Check that out.

I want through the  NI Vision Concepts Manual and I made object classification using USB camera but there is an error of invalid image type so please check my labview coding............My task is to classify the object and display the name of the object on the image and string indicator so how can I do that...............Thank you for helping me.

Hey Sherok-

It is difficult to run this code without your hardware or your classification file. So, you are going to have to do some debugging to see where the error is coming from. Try running your code in highlight execution mode. 

In addition, does your error message tell you anything about what image type it is expecting versus what image time you are using? You should be able to change the image type your program, 'Image Type' is one of the inputs on the IMAQ Create.vi.

Without the classify portion of your code, are you able to simply grab from your USB camera?

Hope this helps.
