measure two circles decentering

[RawanSu]

Good Morning,

I have two images each one contain a curve and I want to make sure that these two curves will make two concentric circle, if not I want to measure the difference?

Could you please advise me on how to do that using Labview vision tool..

Best Regards,

Rawan

Hi Rawan,

My advice would be to use the Find Circular Edge function on each image to extract the x,y coordinates of each circle's center. This information is contained in the Fitted Circle indicator from the Find Circular Edge function. This way, you could do a simple math operation to determine if the distance between the centers is less than your required bounds to be considered concentric.
