Description Field/Button
Use this field to rename the tool. The default is
tool_name_1, tool_name_2, and so on, where the default
tool_name depends on the tool being created (for example,
locate, edge or the like). The name can have only
alphanumeric characters and underscores with no spaces.
Click this button to add an ROI to an image.
Click this button to remove an ROI from an image.
Use this field to rotate the ROI. You can manually key in
a rotation angle, or you can use the up or down arrow keys
to rotate the ROI.
Minimum Acceptance Level
This adjustment sets the acceptance level for pattern matches.
• Decrease the Minimum Acceptance Level to allow more variations in matching patterns.
• Increase the Minimum Acceptance Level to filter out patterns that contain small defects.
Percent match is a value between 20% and 100% that indicates the quality of the match (100% is a perfect match; 20%
is a slight match). The percent match can be used to detect large defects.
Note: Banner does not recommend setting the Minimum Acceptance Level below 70%.
Rotation Enabled
The Pattern Find tool has a +/- 10 degree rotation ability. All subsequent ROIs will rotate relative to the edge found.
During setup, the tool calculates the angle of the pattern found. During inspection, the new angle is compared to the
original angle. If there is any rotational change between the new angle and the original angle, all subsequent ROIs will
rotate that amount.
Selected Pattern
The Selected Pattern field indicates whether the captured image is fine as it is or if there are potential issues. For
example, in the display below, the image is marinal for both translational content and for rotational content.
