Gocator Snapshot Sensors: User Manual
Gocator Web Interface • 100
Setting Description
maximum length, it is automatically separated into two parts. This is useful to break a
long object into multiple sections and perform measurements on each section.
Frame of Reference Determines the coordinate reference for surface measurements.
Sensor
When Frame of Reference is set to Sensor, the sensor's frame of reference is used.
When set to Sensor, all measurement values are relative to the sensor's field of view in X
and relative to the encoder zero position in Y.
Part
When Frame of Reference is set to Part, all measurements except Bounding Box X and
Y are relative to the center of the bounding box of the part. For Bounding Box X and Y,
the measurement values are always relative to the sensor frame of reference (see
Bounding Box on page 189).
Edge Filtering
See Edge Filtering below.
To set up part detection:
1. Go to the Scan page and choose Surface in the Scan Mode panel.
If this mode is not selected, you will not be able to configure part detection.
2. Expand the Part Detection panel by clicking on the panel header or the button.
3. If necessary, check the Enabled option.
When Generation is set to Continuous, part detection is always enabled.
4. Adjust the settings.
See the part detection parameters above for more information.
Edge Filtering
Part scans sometimes contain noise around the edges of the target. This noise is usually caused by the
sensor’s light being reflected off almost vertical sides, rounded corners, etc. Edge filtering helps reduce
edge noise in order to produce more accurate and repeatable volume and area measurements, as well as
to improve positioning of relative measurement regions. Optionally, the Preserve Interior Feature
setting can be used to limit filtering to the outside edges of the target.
