the image coordinate system. The Reference X and Reference Y coordinates of the
point are expressed in pixels.
l
World Distance orders instances according to their proximity to a user-defined point in
the World coordinate system. The Reference X and Reference Y coordinates of the
point are expressed in the user-selected length units.
l
Shading Consistency orders instances according to the custom shading area created in
the model. If no Custom Shading Area is defined in the model, the Locator uses the
entire model area for shading analysis.
This mode is useful when the shading information, in addition to the normal contour infor-
mation, can assist in discriminating between very similar hypotheses. This is a requirement
for color processing of models and also often used for BGA application, as illustrated in the fol-
lowing figure.
Instance Ordering - Shading Consistency
Output Symmetric Instances
The Output Symmetric Instances setting determines how the Locator will handle sym-
metrical or nearly symmetrical objects.
l
When set to false, the search process will output only the first best quality instance of
a symmetric object.
l
When set to true, the search process will output the results for all possible symmetries
of a symmetric object. This can significantly increase execution time when there are
many possible symmetries of an object, for example, if the object is circular.
Timeout
The Timeout setting controls the elapsed time after which the Locator aborts its search proc-
ess. This timeout period does not include the model learning phase. When the Timeout is
