Characteristic
Contour Models Number of different models which should be detected. Up to 10 dif-
ferent models can be taught in.
Pyramid Steps With a value of 0, the algorithm automatically optimizes the number of
model points. A value of 1 specifies that model points will be looked
for in the original image, and thus this setting is the slowest. If the
value is increased to 2, the resolution of the original image is reduced
by means of subsampling. Possible model points are thus also re-
duced and the process is accelerated. It must be noted that although
processing time is reduced as the pyramid steps value is increased,
accuracy is also reduced. We recommend leaving the setting at a
value of 0, i.e. automatic.
Start Angle [deg] This parameter specifies in which negative direction the model can
be turned from the taught-in position. It describes the start angle from
which the angle of rotation is determined on the basis of angle range.
For example, if a start angle of -15° and an angle range of 30° are
selected, the model can move within a range of -15° to +15°.
Angle Range
[deg]
Angle range specifies the possible range of angles of rotation for the
model.
Angle Increment
[deg]
The angle increment parameter specifies the individual increments
within the selected angle range. The angle increment parameter
should be set on the basis of the object’s size. Smaller models have
only a number of different discrete rotations within the image. For
this reason, a larger angle increment should be selected for smaller
objects.
Min Scaling This parameter specifies the lower limit of the possible scaling range
which will be searched. A value of 1 corresponds to the model’s origi-
nal size.
Max Scaling This parameter specifies the upper limit of the possible scaling range
which will be searched. A value of 1 corresponds to the model’s origi-
nal size.
Scaling Incre-
ment
Scaling increment specifies the increment within the scaling range.
As is also the case with the angle increment parameter, scaling incre-
ment should be set on the basis of the object’s size.
