Identifying a circle in camera image

I need to identify circular object using a camera and how do I go about it?

Does the FindCircleVI works?

I tried using that but it doesn't show how I go about it.

Hi

You can use the Imaq Find Circle Edge 3 function to find the circle object in a image. Before going into LabVIEW develop your algorithm in NI Vision Assistant. It will be very easy to use environment, so  you can easily develop your logic.

Hi there, thank you for replying. May I check how do I go about it if inside the vision assistant it says "IMAGE TOO SMALL"

This allows me to track for circular object for moving object right? Thanks for the help!

Change the resolution of image proportionally  for X and Y, by which you can avoid the Small Image Issue.

-Can you provide your code and sample images?

-What camera are you using and how you are acquiring images?

-What type of images are you receiving?(Color, Gray scale, Binary)

-What function/algorithm you are using to detect circles?

-Often it happens that the image is overwritten or destroyed during the processing and it can throw the error image too small.
