26. Adjust the Confusion Threshold if necessary. Confusion Threshold is the maximum score
that could be assigned to a “wrong” feature in the field of view. The Confusion Threshold
should be set greater than or equal to the Accept Threshold. Recommended setting:
500-900.
 If a feature scores higher than the Confusion Threshold, the vision system concludes
that it must be the correct feature and immediately terminates the search.
 If a feature scores above the Accept Threshold, but below the Confusion Threshold, the
vision system will flag the feature as a “candidate” match, but will continue searching
for a better match.
27. Click on the
Run Time tab.

 Check for location tolerances means that FmXP will check the found location of the
fiducial and compare it to the location where it expected to find it. If the difference
between the two locations is greater than the Location Tolerance, FmXP will consider
the fiducial to be “Not Found.”
 This ensures that an incorrect fiducial or other feature is not considered to be a
correct fiducial, and prevents dispensing on parts that are too far away from their
expected locations.
