Key Points for Adjustment
Select the adjustment method referring to the following points.
When the measurement results are unstable
Searching other positions
The judgement is NG (insufficient memory)
When the processing speed is slow
Parameter to be
adjusted
Remedy
Model parameter
Specify a larger value for the "Prec."
If the measurement results are unstable only when "Rot
ation
" 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-pi
xel".
If images that should be judged OK vary greatly, specify a smaller value for "Candidate LV".
If the model image is small and unstable, specify a smaller value for the "Reduction".
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.".
Parameter to be
adjusted
Remedy
Region setting Make the search region as small as possible.
Model register 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
stabil
ity does not speed up processing, it is likely that many candidates have been detected. Raise
the "Candidate level" in [Measurement].
When "Rotation" is selected and the model image is a
simpl
e figure, specify a larger value for
"Skipping angle".
When "Rotation" is selected and the model image is a simpl
e 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".
Measurement
If images that should be judged OK vary little
, specify a larger value for "Candidate level".
If the position precision is high, uncheck "Sub-pixel".
