Judgement of Position Displacement and Subsequent
Measurement
Judgement
OK Measurement is performed after position displace-
ment compensation.
NG Measurement is performed without position dis-
placement compensation. Output to the OR termi-
nal is NG, irrespective of measurement result.
The pixel-skipping parameter for searching for the model can
be changed. The pixel-skipping parameter is determined
according to the speed setting in the evaluation conditions
menu. However, from this screen it is also possible to change
the pixel-skipping parameter directly.
By making the value larger, the processing time can be
reduced. However, the accuracy of the search will be reduced,
and depending on the image, the object may not be found.
After changing the settings, check whether measurement and
search are performed properly.
