closing circle
Specify the circle calculation method.
When the calculation from the smallest enclosing circle is selected,
specify fast speed
or high precision.
Circular Regression:
The circle is calculated with the least square method.
Smallest enclosing circle (Fast):
A circle that encloses all points is calculated.
Smallest enclosing circle (High precision):
A circle that encloses all points and that circumscribes three points is
cal
c
ulated.

a
surement points are eliminated in the order of the largest to the
smallest.
The values beside each item are measurement results of the
