Term Definition
measurement flow
(abbreviated as “flow”)
A continuous flow of measurement processing. A measurement flow consists of a scene
created from a combination of processing items.
measurement processing Executing processing items for inspections and measurements.
processing item
Any of the individual items for vision inspections that are partitioned and packaged so that they can be
flexibly combined.
These include the Search, Position Compensation, and Fine Matching items.
Processing items can be classified for image input ([Input image]), inspection/measurement
([Measurement]), image correction ([Compensate image]), inspection/measurement support
([Support measurement]), process branching ([Branch]), results external output ([Output
result]), resulting image display ([Display result]), etc.
You can freely classify processing items to handle a wide range of applications.
A scene (i.e., a unit for changing the measurement flow) is created by registering the processing items as
units.
scene
A unit for changing the measurement flow that consists of a combination of processing items.
“Scene” is used because of the correspondence to the scene (i.e., type of measurement object
and inspection contents) where measurements are performed.
A scene is created for each measurement or measurement contents.
You can easily achieve a changeover simply by changing the scene when the measurement
object or inspection content changes.
Normally you can set up to 128 scenes. If you need more than 128 scenes, you can separate
them into different groups or use the Conversion Scene Group Data Tool to create a scene
group that contains over 128 scenes.
processing unit
(abbreviated as “unit”)
A processing item that is registered in a scene.
Numbers are assigned to processing units in order from the top and they are executed in that
order.
Processing items are registered for the processing units to create a scene (i.e., a unit for
changing the measurement flow).
measurement trigger
A trigger for executing measurements.
With a parallel interface, the STEP signal or command 00 (Continuous Measurement) is used. With
a serial interface, an Execute One Measurement or a Start Continuous Measurement command is
used.
test measurement
A measurement that is performed to manually test (check) measurements under the conditions
that are set in the currently displayed scene.
Test measurements can be executed on an Adjustment Window. Processing is completed
inside the Controller and the measurement results are not normally output on an external
interface.
However, you can select [Output] in [Test measurement] to output the measurement results
after executing measurements.
single measurement A measurement that is executed only once in synchronization with the trigger input.
continuous measurement
Measurements executed continuously and automatically without a trigger input as soon as
each measurement is completed.
*1
*1: There is actually a small delay between completing a measurement and starting the next
measurement.
“Continuous measurement” is used as opposed to “single measurement.”
