Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 271
Parameter Description
Absolute Threshold When Use Intensity is disabled, the setting specifies the minimum height difference
between points on a path profile for that step to be considered for an edge point.
The setting can be used to exclude smaller steps on a part that should not be
considered for an edge, or to exclude height differences caused by noise. When used in
conjunction with Relative Threshold, Absolute Threshold is typically set to a small
value, greater than the general surface roughness.
In the image below, when Step Threshold is left at the default of 0, all steps are
included as possible candidates for an edge, and will be used to fit an edge line. The
resulting edge line is angled upward to the left.
When Step Threshold is set to 3 with the same data (see image below), steps going from
the yellow to pink regions (roughly 1.37 mm) and from the blue to yellow regions (roughly
