Description
1
Parameters for object search
Light
: Circles to be found automatically are brighter and thus higher than the
surroundings in the region.
Dark
: Circles to be found automatically are darker and thus deeper than the
surrounding area in the region.
NOTE
Image processing refers to height differences, which are displayed as
brightness differences in the heightmap.
2
Check mode
Dynamic
: Check mode for inhomogeneous surfaces with varying height.
Absolute
: Check mode for planar surfaces with a uniform height.
The
Check Mode
setting affects the
Param. Dynamic
and
Param. Absolute
window.
Only the available parameters of the selected
Check Mode
are activated.
3
Minimum height at which the circles for the recesses must be located. This
value indicates how far (in mm) the circle region must be above the surrounding
surface.
4
Minimum diameter (in real dimension [mm]) of the circles to be searched. Small‐
est possible value: 1.0.
Only circles that meet the previous conditions and have the minimum diameter
specified here are searched for.
NOTE
The diameter must not be chosen too small, as this can cause circles
to be placed in structures that do not correspond to the desired circles. These
circles result from the selected parameters and the inhomogeneous surface of
the inspection object. The number of circles found and the number of circles
expected therefore do not match.
