I attach the reference dataset to this post. The file with .DS extension
includes X, Y, Z of the 400 points, and the file with .FIT includes the
result of fitting. The last number in the .FIT file is the diameter of the
least square fit circle. For this dataset that I uploaded, PCL computes the
diameter = 356.697
and NIST diameter = 361.80966768000886515
Can anybody explain to me why they are so different?
It would be great if someone can fit a circle to their dataset using PCL and let us know their results.
