Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 88
Mode and Option Description
Video images are processed internally to produce laser profiles and cross-sectional
measurements.
Surface
Outputs 3D point clouds made up of many laser profiles combined together and
performs surface measurements. The sensor uses various methods to generate a
surface (see on page 113). Part detection can be enabled on a surface to identify
discrete parts (see on page 117).
Uniform Spacing
When this option is enabled, ranges are resampled to a uniform spacing along the X
axis (see on page 53 for more information). The size of the spacing can be set in the
Spacing tab (see on page 103).
When the option is disabled, the Gocator outputs unprocessed range data. Ranges are
reported in (x,z) coordinate pairs. Post-profiling processing is disabled. Only a subset of
the measurement tools is available.
Disable this option to extract ranges from the Gocator at the highest possible rate.
When the sensor is in Surface mode, this option is not available.
Acquire Intensity When this option is enabled, an intensity value will be produced for each
laser profile
point
.
Triggers
A trigger is an event that causes a Gocator sensor to take a single picture. Triggers are configured in the
Trigger panel on the Scan page.
When a trigger is processed, the laser is strobed and the camera exposes to produce an image. The
resulting image is processed inside the sensor to yield a profile (range/distance information), which can
then be used for measurement.
The sensor can be triggered by one of the sources described in the table below.
If the sensor is connected to a Master 400 or higher, encoder and digital (external) input signals
over the IOcordset are ignored. The sensor instead receives these signals from the Master; for
encoder and digital input pinouts on Masters, see the section corresponding to your Master in
Master Network Controllers on page 506.
If the sensor is connected to a Master 100 (or no Master is used), the sensor receives signals
over the IOcordset. For information on connecting encoder and digital input signals to a sensor
in these cases, see Encoder Input on page 504Digital Input on page 503Encoder Input on page
504
Trigger Source Description
Time
Sensors have an internal clock that can be used to generate fixed-frequency triggers. The external
input can be used to enable or disable the time triggers.
