Property
The following settings/results are displayed:
Segments
True Count
The number of detected segments is displayed.
Edge Width “Edge width” influences detection sensitivity for brightness fluctua-
tions.
Note:
• An edge width of 3 pixels reacts to even the smallest contrast
change in the image.
• An edge width of 9 pixels smooths the brightness profile over a
distance of 9 pixels and ignores small irregularities.
Threshold
Gradient Pos
[GrM]
Threshold Gradient Pos specifies the positive gradient acceptance
threshold.
Note: The gradient corresponds to the change in brightness from
one pixel to the next. The higher the edge’s contrast, the larger the
gradient.
Threshold
Gradient Neg
[GrM]
Threshold Gradient Neg specifies the negative gradient acceptance
threshold.
Note: The gradient corresponds to the change in brightness from
one pixel to the next. The higher the edge’s contrast, the larger the
gradient.
Segments
Max Count
Maximum number of segments to be expected.
Segments
Minimum
Length
Minimum length of the segments
Segments
Maximum
Length
Maximum length of the segments
Sort Rule The rule used for sorting segments can be defined.
Position on Search
Geometry
Sorting is based on the position on the
search ray. The results depend on the
orientation setting.
Size [Longest First] Segments are sorted in descending order
beginning with the longest segment.
Size [Shortest First] Segments are sorted in ascending order
beginning with the shortest segment.
Segment
Brightness
This setting specifies whether bright or dark segments will be
evaluated.
Orientation The search direction can be turned 180° with this setting.
