Does OpenCV require NIVision?

[Glibby1234]

Does using Open CV in Labview require the NI Vision Development Module as well? I ask because I'm trying to experiment with Vision and at this time I can't justify the NI Vision price tag. It seemed OpenCV was the answer, but I can't open any of the example without error. 

I installed the OpenCV package, and when I try to use the example VIs it asks me for "NIVISOCVSAMPLES.DLL" (Which I know can be solve dby following: https://www.youtube.com/watch?v=boWp3C0U6gQ) but it also asks me to find "IMAQ Rectangle" / "IMAQ Image" / etc... His video never shows those as missing items. 

I've tried searching around but found nothing. I'd like to get an OpenCV example working before I go around experimenting with different CV functions on my own.

Hello,

Check out this link: https://www.ni.com/en/support/documentation/supplemental/16/developing-vision-applications-using-ope...

It goes over what is required/recommended for the OpenCV utilities. It mentions that Vision Acquisition Software is needed. That software package includes the IMAQ and IMAQdx drivers that provide those APIs in LabVIEW. Vision Development Module is not required but recommended. 

Hope this info helps!

D'oh! I glossed over that page and thought Vision Acquisition and Vision Development were the same thing! 

What exactly does Vision Acquisition let you do? I've gotten cameras working before without that.

It happens!

Here is a little brief overview of Vision Acquisition Software!: https://www.ni.com/en-us/shop/product/vision-acquisition-software.html

If you have used some of our software you might have used some of our vision packages in the past. For third party software you may not need some of these packages to use the camera. 

We have plenty of other options too: https://www.ni.com/en/support/documentation/supplemental/18/licensing-national-instruments-vision-so...

Glad I could help!
