FH/FZ5 Processing Item Function Reference Manual
Changing Model Parameters
Model parameter values can be changed as needed to address unstable measurement results or to increase the
processing speed. Normally, the factory default value will be used.
After changing a setting, re-register the model.
1 In the "Model parameter" area, select the
search mode, then specify a value for
each item for that mode.

Description
Search mode
[CR]
Search for normalizing the brightness. This method can provide stable
measureme
nt
when there is fluctuation in the overall brightness and when
the image has low contrast.
PT
Measures the degree of matching with the profile. Th
is method can
measure at higher speed when the rotation angle has a wide range.
It is available only when a 0.3 megapixel color camera is connected.

Description
Rotation
• Checked
•[Unchecked]
When the measurement object is rotating, place
a check at "Rotation" and
specify how many degrees the model created rotates each time and
through what range of angles. A smaller skipping angle increases
stability, but slows down the processing. The forward direction is
clockwise.
