How to overlay a pattern on live video capture in LabVIEW

[Swati.Bh]

Hi Pallen,

This is what I have been ultimately trying to do.  I have shown in the snapshot below. I want to overlay these circles on live video from my camera.

Looks like I cannot directly attach the output array from circle test VI to IMAQdx.Grab , any thoughts on what I need to do to connect these? Are there ways in labview to convert the types and make this happen?

I have also attached the same file whose snapshot I have shown below.

Thank you!!

I think this code might be a little closer to what you are trying to do.

Yes, for sure, it is so close to what I've been trying to do!!!!

Thank you soooo much Pallen!!!! 

I'll explore to extend this and I hope I will be able to add more circles and lines to this, I was using similar approach of using overlays which I have posted earlier but wasn't landing on the right track. I really very much appreciate all your help!! I'm glad to be connected to this community and thank everyone in this community who are helping each other and newbies.

Best Regards,
