Parallel processing splits part of the measurement flow into two or more tasks, and
processes each task in parallel to shorten the transaction time.
Processing items for parallel processing are used so that the user can specify the
required parallel processing.
A function that is used to consecutively and quickly input images.
It allows the next STEP signal to be acknowledged as soon as the image input
processing is completed. There is no need to wait for measurement processing to
be completed.
You can check whether image input processing has been completed with the status
of the READY signal. Even if the READY signal is ON when measurement proc-
essing is being executed, the next STEP signal can be acknowledged.
When the location and direction of measured objects are not fixed, the positional
deviation between reference position and current position is calculated and meas-
urement is performed after correcting.
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.
Definition
Measurement area
Object to be measured
Object to be measured
overflows Measurement area.
Measurement will be carried out after
moving the Measurement area for a
corresponding deflection.
