I don't seem to find an algorithm to calculate the center of a circle given a set of noisy data (on the circumference of the circle) on an arbitrary Plane in 3D.
I did try different approached as to calculating the center by only taking 3 points at a time and then averaging the centers, yet I believe there must be a better solution to optimize the center by minimizing the distance to all points. Does anyone have an Idea?
Any Ideas or approaches would be highly appreciated!
