STEP 3: Setting Measurement Methods
This section describes how to inspect for defects using the Fine Matching pro-
cessing item.
The registered image for an acceptable product and the input image are over-
laid (matched) and the differences are detected. This enables small defects in
the pattern and writing on the measurement object to be detected with a high
level of accuracy.
Use the following procedure to set Fine Matching for unit 1.
