What is the unit for roundness measurement in CircularEdgeReport_struct?

Hi-

I thought that roundess was in % but it looks like I get higher than 100 for this value.  Can anyone tell me what the unit is for the roundess value in this structure?

Thanks in advance-

Hi Blue,

Can you please post what library/driver you are using to access this structure?

HI- Thanks for the reply.  This is in the nimachinevision.fp instrument/library.

Hi Blue,

According to this, it looks like the roundness may be reffering to the least square error of the fitted circle to the entire set of points. 

For more information, you may want to try posting to the Machine Vision Forum.
