Hi,
I have a circle that I need to find the center of, as accurate as possible.
Is there a way to find the "physical" center of the circle accurately? -The circle often appears as a very large ellipse in the camera image (covering maybe as much as 60% of the image). The position and orientation of the camera relative to the circle might alter very much. This is not an "assembly line" application.
I have tried using center of mass (http://forums.ni.com/ni/board/message?board.id=200&message.id=4774), and also using imaqFindCircularEdge() in combination with imaqFitEllipse() with limited success.
Is there a method that is robust to size and rotation relative to the camera image?
Thanks,
Torbjørn
