Hi everyone,

I'm pretty new with Labview and Vsion and NOW i'm doing a project but I have some problems..

One part of my project include transfering images from the module where I get the images from the camera to the analysis module. When I run this, the images transfered successfully but then I get an error at the analysis module (-1074396154- IMAQ BCG Lookup) and i don't know how to solve that.. (I don't get that error when I run the analysis module alone).

Another problem that I have is in the analysis module.. I'm trying to find the pupil in the image using find circular edge but it just can't  find it no matter how clear is the pupil (after some filters and manipulations).

(I attach all the VIs for the first question in the first zip file and the two other files for the second question in the second zip file)

please.. if someone can help me i'll be very grateful! 🙂

Make sure you are passing the image itself to the analysis system and not the memory reference. 

As for your second question would it be possible for you to include some sample images that you have acquired? This would help in troubleshooting the second question you have.

The first problem is solved, thank you!

About the second one, I've included one image in the second zip file, but here are some more images, I'll be happy for any help with that.

Try the Vision Assistant for Circle Finding. If it works there, export the script to LabVIEW. I always do it like this and usually does the trick quite well. The thing is, that the Assistant automatically chooses the best applicable values for all the parameters concerning the respective image you analyse with it.

That's what I did.. that code is what I got after exporting the script from Vision Assistant to Labview.. but it still doesn't work 😞

I was able to find your pupil by using Find Circual Edge in Vision Assistant (see attached). You could likely obtain a more reliable result by playing with the settings and performing some filtering as you mentioned.
