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.

In the "Model parameter" area, select the
search mode, then specify a value for
each item for that mode.

Search
Set value
[Factory default]
Search for normalizing the brightness. This method can provide stable
[CR] measurement when there is fluctuation in the overall brightness and when
the image has low contrast.
Measures the degree of matching with the profile. This method can
PT 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
[Factory default]
• Checked
When the measurement object is rotating, place a check at "Rotation" and
• [Unchecked]
specify how many degrees the model created rotates each time and
[-180 to 180] through what range of angles. A smaller skipping angle increases
stability, but slows down the processing. The forward direction is
1 to 30
clockwise.
[5]
Checking the "Smart mode" option enables a high-speed rotation search.
• [Checked]
However, the stability may be lowered when the model shape aspect ratio
• Unchecked
is large or when the NOT mask is used.
1 to 15
Specify which is to have priority, measurement stability or speed.

If lowering stability does not speed up processing, it is likely that many

"Candidate LV" or "Stab."
9 or 12]
1 to 3 Specify which is to have priority, measurement positional precision or
[2] speed.
Set value
[Factory default]
This item specifies the rotation angle range for searching. The normal
[-180 to 180]
direction is clockwise.
If lowering stability does not speed up processing, it is likely that many
1 to 5
candidates have been detected. In this case, specify a larger value for

"Candidate LV" or "Stab."
