7.7. Pattern Match
• Description
The term pattern match signifies a process that searches for a pattern similar to the master
image inside the target image using its brightness matrix. (Pattern Match
)
Once the ROI has been set, the control calculates the edge points (features) that show significant
differences in pixel brightness.
NOTE:
the image used by the algorithm to perform the comparison used as the inspection base
can by defined by the user in the Setup stage using the TEACH button. If the user moves on to
the Adjust phase before setting any reference images, the inspection algorithm will use the first
frame it acquires after the tool is selected. If you are not happy with the current choice, you can
select a new reference image by returning to the Setup phase using the ESC button.
