When the location and direction of measured objects are not fixed, the positional
deviation between reference position and current position is calculated and meas-

Please select processing items that are appropriate to the measurement object
from processing items that are related to position compensation.
Reference position
Measurement area and objects to be measured
are correctly aligned.
When position of object to be measured is deflected
When position deflection correction is set in advance:
Measurement will be carried out
after moving the image for a
corresponding deflection and
returning to the reference position.
Measurement will be carried out
after measured object enters into Measurement area.
The point that is always the reference. If the location of the registered model is dif-
ferent from the reference position, the setting should be changed in Ref. setting.
The image pattern that serves as the inspection target. Characteristics portions are
extracted from images of the object and registered as model registration.
