Key Points for Test Measurement and Adjustment (Classification)

Key Points for Test Measurement and Adjustment (Classification)

The following content is displayed in the "Detail result" area as text.

Displayed items	Description
Judge	Judgement result
Index	Index No. of the biggest correlation
Model number	Model No. of the biggest correlation
Correlation	Correlation with the model
Position X	X coordinate of the position where the model is detected
Position Y	Y coordinate of the position where the model is detected
Angle	Angle of the position where the model is detected

Key Points for Adjustment

Select the adjustment method referring to the following points.

When the measurement results are unstable

Searching other positions

Parameter to be adjusted	Remedy
Model parameter	Specify a larger value for the "Preciseness"
	If the measurement results are unstable only when "Rotation" is selected, specify a smaller value for the "Skipping angle".
	When "Rotation" is selected, if the model shape is complex, uncheck the "Smart mode" option.
	If the image has low contrast or blurred edges, set the "Search mode" to "CR".
	If the model image consists of detailed figures, specify a larger value for "Stab."
Measurement	If the precision is low, place a check at "Sub-pixel".
	If images that should be judged OK vary greatly, specify a smaller value for "Candidate level".
	If the model image is small and unstable, specify a smaller value for the "Reduction".

The judgement is NG (insufficient memory)

Parameter to be adjusted	Remedy
Region setting	Make the search region as small as possible.
Model parameter	Bring "Stab." close to the factory default value.
	Bring the "Skipping angle" close to the factory default value.
	Specify a smaller value for "Prec.".

When the processing speed is slow

Parameter to be adjusted	Remedy
Region setting	Make the search region as small as possible.
Model	Make the area to register as the model as small as possible.
Model parameter	If the model image is a simple figure or a large figure, specify a smaller value for "Stab."If lowering stability does not speed up processing, it is likely that many candidates have been detected. Raise the "Candidate level" in [Measurement parameter].
	When "Rotation" is selected and the model image is a simple figure, specify a larger value for "Skipping angle".
	When "Rotation" is selected and the model image is a simple figure, place a check at "Smart mode".
	If the position precision is high, specify a smaller value for "Preciseness".
	If the rotation angle range is large, set the "Search mode" to "PT".
Measurement	If images that should be judged OK vary little, specify a larger value for "Candidate level".
Measurement	If the position precision is high, uncheck "Sub-pixel".
