Key Points for Test Measurement and Adjustment (Sensitive Search)

Key Points for Test Measurement and Adjustment (Sensitive Search)

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

Note

Executing test measurements will also update the measurement results and the figures in the image.

Displayed items	Description
Judge	Judgement result
Correlation value	Lowest correlation value in the sub-region
Measure X	X coordinate of the position where the model is detected
Measure Y	Y coordinate of the position where the model is detected
Angle θ	Angle of the position where the model is detected
Deviation	Highest density deviation in the sub-region
NG Sub-region	NG region count

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 "Prec."
	If the measurement results are unstable only when "With rotation" is selected, specify a smaller value for the "Skipping angle".
	When "With rotation" is selected, if the model shape is complex, uncheck the "Smart mode" option.
	If the model image consists of detailed figures, specify a larger value for "Stab."
Sub-model parameter	If images that should be judged OK vary greatly, specify a larger value for "Sub-model number X" and "Sub-model number Y".
Measurement parameter	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 LV".
	If images that should be judged OK vary greatly, specify a larger value for "Sub-region margin".

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.".
Sub-model parameter	Specify a larger value for "Sub-model number X" and "Sub-model number Y".

When the processing speed is slow

Parameter to be adjusted	Remedy
Region setting	Make the search region as small as possible.
Model Registration	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 LV" in [Measurement].
	When "With rotation" is selected and the model image is a simple figure, specify a larger value for "Skipping angle".
	When "With 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 "Prec.".
Sub-model parameter	If images that should be judged OK vary greatly, specify a larger value for "Sub-model number X" and "Sub-model number Y".
Measurement parameter	If images that should be judged OK vary little, specify a larger value for "Candidate LV".
Measurement parameter	If the position precision is high, uncheck "Sub-pixel".
