Click the Pattern Matching icon to display the dialog box shown below.
From the Dimension tab, you will see the object that was outlined using the ROI icon.
From the Search tab, click All.
From the Angle tab, check Enable Search With Rotate. Then enter 180 for Delta Negative, and 180 for Delta Positive (this enables a full 360-degree search).
Save the Pattern Matching Model in the Pattern Folder, located in the ViewFlex root folder. Ensure that the Pattern dialog box is selected when saving.
The pattern matching model is now ready to be used for performing inspection.
Performing Inspection by Pattern Matching
The pattern matching model is searched in the image for inspection of the object by using the Search tab as shown in the figure above. This will build a Measurement Table as shown below containing all the positions of the object relative to the pattern matching model along with the % score that reflects the correspondence between the image of the object and the pattern matching model.
