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
Specify a larger value for the "Prec."
If the measurement results are unstable only when "Rotation" is selected, specify a smaller value
for the "Skipping angle".
Model parameter
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."
If the precision is low, place a check at "Sub-pixel".
Measurement
If images that should be judged OK vary greatly, specify a smaller value for "Candidate LV".
parameter
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
Region setting Make the search region as small as possible.
Bring "Stab." close to the factory default value.
Model parameter 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
Region setting Make the search region as small as possible.
Model registration Make the area to register as the model as small as possible.
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 "Rotation" is selected and the model image is a simple figure, specify a larger value for
"Skipping angle".
Model parameter
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 "Prec.".
If the rotation angle range is large, set the "Search mode" to "PT".
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".
