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 judgment for the same image pattern even when the object is at an angle, the rotation range
must be widened.
