Unstable Search Results
Inclined Measurement Objects
Adjust the [Angle range] parameter to increase the range in which a search is made for the model.
The Search inspection item judges whether an image is OK or NG according to the correlation with a
previously registered image pattern. For this reason, if the object is at an angle, the correlation is reduced and
the image may be judged as NG. To achieve an OK judgement for the same image pattern even when the
object is at an angle, the rotation range must be widened.

Correlation Is Inconsistent Due to Low Contrast
Adjust the brightness to improve the contrast of the mark.
Adjust the brightness: p. 61
Correlation Is Inconsistent Due to Variations in the Measurement Object
Inconsistent portions can be masked so that they are omitted from matching.
Model masking: p. 101
Increasing Processing Speed
The following two methods can be used to reduce processing time.
• Reduce the range in which a search is performed for the model.
Changing the measurement region: p. 102
• Reduce the angle range setting.

Description
Angle range
Range:
−
180 to 180
Default: Lower limit:
−
180,
Upper limit: 180
A search is performed within the set angle range.
The larger the angle range, the longer the processing time.
If you change the angle range, perform teaching again.
