Search
The scale of objects to be located can be set at a fixed nominal value, or as a range of scale
values.
The default setting for the scale factor is a nominal value of 1, which applies to most sit-
uations.
If objects have a slight variation in scale, the objects may be recognized and positioned with
reduced quality because their true scale factor will not be measured. In such a case, it is pref-
erable to configure a narrow scale range, instead of a nominal value.
NOTE: Using a large scale factor can significantly slow down the search process. This
range should be configured to include only the scale factors that are actually expected for
a given application. The scale factor range is one of the parameters that has the most sig-
nificant impact on search speed.
Use Nominal
Search for a specific scale factor. Note that when a nominal value is used, the
Locator does not compute the actual scale of instances; instead, the instances
are positioned using the Nominal scale value. When Nominal is checked, the
Nominal scale factor is applied.
Disable the Use Nominal checkbox to specify the range of scale the Locator will
search for. If you want to search for an instance at a nominal scale factor, but
need to compute its actual scale, disable the Nominal checkbox and enter a
small range, such as 0.99 to 1.01.
Nominal
A value, from 0.1 to 10. A Nominal scale factor of 1 is set by default.
Maximum
The maximum scale factor that the Locator will look for. This must be less than
or equal to 10, and greater than or equal to Minimum.
Minimum
The minimum scale factor that the Locator will look for. This must be greater
than or equal to 0.1, and less than or equal to Maximum.
Positioning Level
Allows you to modify the positioning accuracy. The default setting of 5 is the optimized and
recommended setting for typical applications. Positioning Level can be from 0 to 10.
A value of 0 will provide coarser positioning and faster execution time. Conversely, a value of
10 will provide high-accuracy positioning of object instances.
