Key Points for Test Measurement and Adjustment (ECM Search)

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

Displayed items	Description
Judge	Judgement result
Correlation value	Correlation value
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

Key Points for Adjustment

Select the adjustment method referring to the following points.

When the measurement results are unstable

Parameter to be adjusted	Remedy
Measurement parameter	If images that should be judged OK vary greatly, specify a smaller value for "Candidate LV".
Measurement parameter	If the model image is small and unstable, specify a smaller value for the "Reduction".
Model Registration	Mask any unnecessary items.
	Lower the edge level.
	Register the error model.
Model parameter	If the measurement results are unstable only when "With rotation" is selected, specify a smaller value for the "Skipping angle".

When the processing speed is slow

Parameter to be adjusted	Remedy
Region setting	Make the search region as small as possible.
Model parameter	If images that should be judged OK vary little, specify a larger value for "Candidate LV".
Model parameter	When "With rotation" is selected and the model image is a simple figure, specify a larger value for "Skipping angle".
Measurement parameter	Specify a smaller value of the "Reduction".
	Specify a larger value of the "Model skipping".
	Specify a larger value of the "Search skipping".
