processing a video from a web cam

[hah49]

Hello , 

I hope you can help me as mush as you can..

I'm working on a project and i need to process a video sent from a web cam and to send the corresponding message.

For example if I see an obstacle, i have to display a warning Note on the screen to stop the machine or something like that.

I've been searching the forum to find a related subject but i found nothing.

Can you please tell me which block to use ? i mean the main blocks and i will do the research in order to know how each block can be used.

Thanks alot for your time 🙂

Regards

Hey hah,

good name 🙂

You can use a webcam just as any other image acquisition device, if it is supported by the NI Vision Acquisition Software. (many cameras are)

If you need vision processing, I do recommend VBAI as a great tool to start familiarizing yourself with the capabilities of the NI Vision platform. Many applications can be solved using this tool alone.

The NI Vision Assistant is the next best step, you can simply use it to generate LabVIEW code based on menu-based configuration.

And of course if you need fuly customized functionality, you can allways use LabVIEW.

This article gives a good overview of the various Vision SW offerings form NI.

And for a comprehensive tutorial, I recommend the NI Vision Concepts Help.
