Gocator Line Profile Sensors: User Manual

Measurement Illustration
Height
Determines the height (thickness) of the bounding box that
contains the profile.
Global X
*
Determines the X position of the center of the bounding
box that contains the profile relative to the surface from
which the profile is extracted.
Global Y
*
Determines the Yposition of the center of the bounding
box that contains the profile relative to the surface from
which the profile is extracted.
Global Angle
*
Determines the angle around Zof the section used to create
the profile, relative to the surface from which it is extracted,
where a line parallel to the X axis is 0 degrees.
Angles of sections pointing to the bottom of the data viewer
are positive.
Angles of sections pointing to the top of the data viewer are
negative.
*The Global X, Global Y, and Global Angle measurements are intended to be used with profiles
extracted from a surface using a section.
When used with profiles not generated from a section, the Global X measurement returns the
same value as the X measurement, and the Global Yand Global Angle measurements return
0.000.

Parameters
Bridge Value
The Bridge Value tool lets you calculate the "bridgevalue" and angle of a scanned surface. Abridge
valueis a single, processed range that is basically a filtered average of a laser line profile, representing a
"roughness calculation." Abridge value is typically used to measure road roughness.
The Bridge value tool is only available when Uniform Spacing (in the Scan Mode panel on the
Scan page)is unchecked, as the tool only works with unresampled data. For more information,
see Uniform Spacing (Data Resampling) on page 53.
This measurement is only available on Gocator 2342 sensors.
