8.5.3. Contour Match
Description
The contour match operation consists in comparing the contour of a sample object with that of a
target object to determine their similarity. (Contour match ►)
After an initial setup stage designed to set the master contour on the reference image, it’s very
important that the ROI contains a closed shape entirely. Then, the system will search for this contour
through 360° in target images as they are acquired. A numeric value (score) is returned by the tool,
the more high the more the processed shape is similar to the reference one.
Inspection tolerance may be modified.
