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.

Set value
Search normalizing the brightness. This method can provide stable
measurement when there is fluctuation in the overall brightness and when the
image has low contrast.
Measures with the degree of matching to the profile of the model. This 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.

Set value
This item specifies the rotation angle range for searching. The normal direction
is clockwise.
If lowering stability does not speed up processing, it is likely that many
candidates have been detected. In this case, specify a larger value for
"Candidate level" or "Stab."
Description
Description
When the measurement object is rotating, select the "Rotation"
check box 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 normal direction is clockwise.
Checking the "Smart mode" option enables a high-speed rotation
search. However, the stability may be lowered when the model
shape aspect ratio is large or when the NOT mask is used.
Specify which is to have priority, measurement stability or speed.
If lowering stability does not speed up processing, it is likely that
many candidates have been detected. In this case, specify a
larger value for "Candidate level" or "Stab."
Specify which is to have priority, measurement positional
precision or speed.
