Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 267
Parameter Description
Source The sensor, or combination of sensors, that provides data for the tool's measurements. For
more information, see Source on page 201.
Stream The data that the tool will apply measurements to.
In Surface mode, this setting is only displayed when a section is defined on the surface
data.
For more information on sections, see Sections on page 190.
Reference Direction Defines the side used to calculate the rounded corner.
Max Gap Width The maximum width of the gap. Allows the tool to filter gaps greater than the expected
width. This can be used to single out the correct gap when there are multiple gaps in the
field of view.
Filters The filters that are applied to measurement values before they are output. For more
information, see Filters on page 209.
Decision The Max and Min settings define the range that determines whether the measurement
tool sends a pass or fail decision to the output. For more information, see Decisions on
page 208.
Parameters
Parameter Description
Max Void Width The maximum allowed width of missing data caused by occlusion or data dropout.
Min Depth Defines the minimum depth before an opening could be considered to have a potential
edge. The depth is the perpendicular distance from the fitted surface line.
Surface Width The width of the surface area in which data is used to form the fitted surface line. This
value should be as large as the surface allows.
Surface Offset The distance between the edge region and the surface region.
Setting a small value allows the edge within a tighter region to be detected. However, the
measurement repeatability could be affected if the data from the edge are considered as
part of the surface region (or vice versa). A rule of thumb is to set Surface Offset equal to
Nominal Radius.
Nominal Radius
The radius of the curve edge that the tool uses to locate the edge region.
Edge Angle
A point on the best fit circle to be used to calculate the feature point. The selected point
is on the circumference at the specified angle from the start of the edge region.
The angle is measured from the axis perpendicular to the fitted surface line.
Edge Type
Defines the type of feature point to use for the edge (Corner or Tangent).
A tangent edge point is the point selected based on the defined Edge Angle. A corner
edge point is the intersect point between the fitted surface line and a edge line formed
by interpolating the points at and after the tangent within the edge region.
Region The region to which the tool's measurements will apply. For more information, see Regions
on page 201.
