Hello,

I am iterested in how is the error between individual tie points calculated during the registration with sphere targets?

Is it some sort of standard deviation of the sphere fitting? ...or is it a difference between transformed tie points and the reference points? or something else?

The error is always the distance between the tie point and the reference one (whatever the case). The sphere fitting part is only used to more accurately position the points (by considering the sphere center instead of a picked point)

Thank you!
