Computer Vision Pattern Recognition
Filter set too loosely (too far to the right.)
Move the Pattern Recognition Filter slide bar further left until
the desired patterns are the only ones identified by the
yellow circles.
User defined Pattern Recognition
Selection Box includes additional space
outside the pattern.
When drawing the rectangle around the desired pattern, it is
good practice to keep the rectangle as close to the featured
pattern as possible. When there are large open areas around
the feature, the Vision System may become confused as to
what exactly is the pattern to be identified. Only select what
is necessary to identify a pattern (refer to pattern recognition
section of manual for more detail.)

Patterns
Unevenly distributed lighting on
workpiece.
Uneven lighting will cast shadows or produced localized
bright spots on a work piece. This will have adverse effects
on the pattern recognition software. Although to the human
eye objects may be known to be the correct pattern, shaded
features will be treated separately from well lit features.
Therefore, keep lighting evenly distributed and diffuse
across the entire workpiece. Choose an installation location
in which lighting is controlled.
Dirt/Debris/Markings on workpiece
The software will identify features with dirt/debris/ or
markings as completely separate features than those that are
perfectly clean. Therefore, keep all workpieces visually
clean by cleaning with isopropyl alcohol or appropriate
cleaning solution. Do NOT mark workpieces with tape or
permanent marker unless the they are identical from board
to board.
User defined Pattern Recognition
Selection Box includes additional features,
not relevant to pattern.
When drawing the rectangle around the desired pattern, it is
good practice to keep the rectangle as close to the featured
pattern as possible. When there are large open areas around
the feature, the Vision System may become confused as to
what exactly is the pattern to be identified. Only select what
is necessary to identify a pattern (refer to pattern recognition
section of manual for more detail.)
