Unstable Shape Search II Results
Inclined Measurement Objects
Adjust the [Angle range] parameter to increase the range in which a search is made for the model.
The Shape Search II 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.

Description
Angle range
Range:
−
180 to 180
Default: Lower limit:

180,
Upper limit: 180
A shape search II 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.
