Match Menu - Banner iVu Plus TG Series Instruction Manual

The Minimum Pass Count is the minimum number of pixels expected to fall within the specified criteria. The Maximum Pass
Count is the maximum number of pixels expected to fall within the specified criteria. These settings are used to determine
the pass or fail result of the inspection.

9.1.3 Match Menu

Main Menu > Inspection > Sensors > Match
Use a Match sensor to verify that a pattern, shape, or part in any orientation matches a reference pattern. Teach the
reference pattern during setup. A reference pattern might include alphanumeric characters, logos, or any other shapes.
During an inspection, the sensor checks that each part or package being inspected matches the reference pattern. If there
is more than one of the identified pattern, set the number of expected matches.
Example applications include:
• Date/Lot code inspections
• Label inspections
• Part etching inspections
• Part orientation inspections
• Part shape inspections
To configure a Match sensor, set the following parameters:
• Teach ROI Type
• Percent Match
• Rotation Range
• Pass Count
• Edit Pattern
• Advanced
• Timeout
To see a working example of the sensor configured as a Match sensor, see Demo Mode.
Teach ROI Type
Main Menu > Inspection > Sensors > Match > Teach ROI Type
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).
Percent Match
Main Menu > Inspection > Sensors > [Sensor Type] > Percent Match
Percent Match adjusts how closely the inspected part or label must match the reference part or label. The Percent Match
scale is from 0 to 100, where 0 is the most tolerant and 100 is the least tolerant. Move the slider to adjust the tolerance.
Rotation Range
Main Menu > Inspection > Sensors > [Sensor Type] > Rotation Range
Rotation Range sets the expected rotation of parts or labels during an inspection. For example, a value of 45 means that the
part may rotate 45 degrees in either direction from the reference part and still pass. Move the slider from 0 to 180 degrees.
Note: The smaller the rotation range, the faster the inspection will run.
