finding circles problem

[youm]

Hello,

I have a usb camera connected and I want to detect circles on images.

My code is very simple (see attachment).

First, I convert my RGB to Grayscale and then apply  "IMAQ Find circles VI"

but even in very simple cases, it finds 0 circle.

Can someone help me ?

Thanks

Youm

A code snippet rather than an image would help you get an answer quicker.

Hello youm,

Thank you for posting on National Instruments' forum.

I think this link could help you in using circle data in output of the IMAQ Find Circles VI : here

However, put the IMAQ Create in your loop and use IMAQ Dispose afterwards (like the example).

Exactly what I was looking for ! Thanks.
