Parameter Description
Reference SideDirection Defines the side used to calculate the measurement axis (see below) 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.
Measurement Axis
Gap measurement only
Defines the direction that the gap is calculated, in relation to the reference side (see
above).
Surface : In the direction of the fitted surface line of the reference surface.
Edge : In the direction perpendicular to the edge of the reference surface.
Distance : The Cartesian distance between the two feature locations.
Absolute
Flush measurement only
When enabled, returns an absolute value rather than a signed value.
Filters The filters that are applied to measurement values before they are output. For more
information, see Filters on page 192.
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 191.
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 laser 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 184.
