Angle Range Pat-
tern
The maximum possible range of rotation of the image in relation to the
trained pattern.
No Rotation: This is the fastest setting
+ - A Few Degrees: uses the Angle Range property value
0 And 180 + - A Few Degrees: uses the Angle Range property value plus
180 degrees. For example, if the Angle Range is -5 and 5, the tool
searches for patterns rotated from -5 to +5 and 175 to 185 degrees.
Full 360 Degree Range: Searches for all rotations. (The Angle Range
property does not need to be set.)
If a pattern is not found, it could be because the image is rotated beyond
this Angle Range.
Angle Range This is the maximum start and end angle, in degrees, that the tool
searches in the image for a match of the trained pattern when the Angle
Range Pattern property is set to + - a Few Degrees. Typically this value
is -5 and 5, indicating that the image may rotate up to 5 degrees counter-
clockwise or clockwise from the trained pattern.
Angle Range Step
Type
When searching for rotated patterns, the tool searches at specific rota-
tions within the Angle Range, separated by the Angle Range Step.
Fixed Steps: Enter the step value in the Angle Range Step property.
Automatic Steps: Angle Range steps are calculated automatically when
the pattern is trained. The value is reported in the Actual Angle Range
Step output property.
Angle Range Step The value to use for the Angle Range Step Type property when Fixed
Steps is selected. The value is in degrees. If the tool misses patterns at
certain rotations, use a smaller value. The tool runs faster with a larger
value.
Scale Range Pat-
tern
Scaling is involved if the size of the pattern can vary from one image to
the next.
No Scaling: Don’t search for any scaling. This is the fastest method and
most inspections do not involve scaling.
Slight Scaling: The scaling may be between + and - 10%
Use Scale Range Settings: The Scale Range property value is used for
scaling.
If a pattern is not found, it could be because it is scaled beyond this
range.
Scale Range The amount of scaling used for the Scale Range Pattern when Use
Scale Range Settings is selected. The values are plus and minus scale
multipliers. For example, a range of 0.5 and 2.0 means the pattern can
be scaled anywhere between half size (0.5) to double size (2.0).
Scale Range Step
Type
When searching for scaled patterns, the tool searches at specific scale
multipliers within the range, separated by the Scale Range Step.
Use a smaller value if the tool misses patterns at certain scaling values.
Use a larger value to make the tool run faster.
Automatic Steps: Scale Range steps are calculated automatically when
the tool is trained and reported in the Actual Scale Range Step output
property.
Fixed Steps: Enter the step value in the Scale Range Step property.
