circle]
•Smallest
en
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.
•[Fast]
• Precision
Removed area num
0 to 360
[0]
Set the number of regions to remove.
The differences from the circular regression calculated from all
me
a
surement points are eliminated in the order of the largest to the
smallest.
• The values beside each item are measurement results of the
displayed image. Take these values into
consideration to determine the upper and lower limit values.
