Blemish Menu - Banner iVu Plus TG Series Instruction Manual

ROI and Mask
Main Menu > Inspection > Sensors > [Sensor Type] > ROI and Mask
Sensor Type in the menu path above refers to the sensor you are configuring or updating.
Note:
The Region of Interest (ROI) is the user-defined area on the screen that the sensor analyzes. The ROI type can be
rectangular, elliptical, or circular. From the drop-down list, select the ROI type to use for the inspection. Adjust the ROI as
appropriate for the inspection. An ROI can be as large as the entire Field of View (FOV).
Select the Enable Mask checkbox to allow mask ROIs to be used with the inspection ROI.
Intensity Range
Main Menu > Inspection > Sensors > Area > Intensity Range
Intensity Range is the range of grayscale values the sensor should look for. To set the Intensity Range, use the eye dropper
to select the target feature. Use the slider to fine tune the selection. As the slider is moved, green highlighted areas indicate
the objects the sensor finds.
Note: Objects that are colored yellow are found, but filtered out. This is because these objects fall outside
of the Area Range. See
Area Range
Main Menu > Inspection > Sensors > [Sensor Type] > Area Range
Use Area Range to set the size limits of a feature of interest. Move the slider to select the range. Areas are measured by
counting pixels. For example, a rectangular feature that is 100 pixels wide by 200 pixels tall has an area of roughly 20,000
pixels.
Pass Count
Main Menu > Inspection > Sensors > [Sensor Type] > Pass Count
The Minimum Pass Count is the minimum number of parts, labels, or features expected to fall within the specified criteria.
The Maximum Pass Count is the maximum number expected to fall within the specified criteria. These settings are used to
determine the pass or fail result of the inspection.
Pass Total Area
Main Menu > Inspection > Sensors > [Sensor Type] > Pass Total Area
Use Pass Total Area to set the desired total area of all features that the sensor must find in order to pass the inspection.
Move the slider to select the range. Areas are measured by counting pixels. For example, a rectangular feature that is 100
pixels wide by 200 pixels tall has an area of roughly 20,000 pixels. Two features of this size have an area of roughly 40,000
pixels.
