Gocator 2300 & 2880 Series
Gocator Web Interface • Models and Part Matching • 122
Setting Description
Match Algorithm Determines which algorithm the sensor will use to attempt a match.
Set this to
Edge for edge detection.
Image Type
Determines what kind of data the Gocator will use to detect edges and therefore
for part matching. Choose this setting based on the kinds of features that will be
used for part matching:
Heightmap: Surface elevation information of the scanned part will be used to
determine edges. This setting is most commonly used.
Intensity: Intensity data (how light or dark areas of a scanned part are) will be
used to determine edges. Use this setting if the main distinguishing marks are
printed text or patterns on the parts. The Acquire Intensity option must be
checked in the Scan Mode panel on the Scan page for this option to be
available.
Z Angle Corrects the orientation of the
model
to accurately match typical orientation and
simplify measurements.
Target Sensitivity (Target
Matching tab)
Controls the threshold at which an edge point is detected on the target's
heightmap or intensity image. (The "target"is any part that is matched to the
model and which will subsequently be measured if the match is accepted.)
Setting Target Sensitivity higher results in more edge points. Setting it lower
results in fewer edge points and results in higher performance. Use this setting to
exclude noise from the detected edges and to make sure distinguishing features
are properly detected.
The level of this setting should generally be similar to the level of Model
Sensitivity.
Model Sensitivity
(Model Editing tab)
Controls the threshold at which an edge point is detected on the heightmap or
intensity image used to create the model. Setting Model Sensitivity higher
results in more edge points. Setting it lower results in fewer edge points and
results in higher performance. Use this setting to exclude noise from the detected
edges and to make sure distinguishing features are properly detected.
The level of this setting should generally be similar to the level of Target
Sensitivity.
Changing this setting causes the edge detection algorithm to run again at the new
threshold. If you have edited edge points manually (removing them selectively),
those changes will be lost. See Using Edge Detection on page 120 for more
information.
Edge Points
(Model Editing tab)
The Edit button lets you selectively remove edge point that are detected by the
edge detection algorithm at the current Model Sensitivity setting. See Using
Edge Detection on page 120 for more information.
Acceptance Criteria
Determines the minimum quality level of the match as a percentage value.
Part rejected:Quality result is less than Min
To run part matching, simply make sure that the Enabled option is checked on the Part Matching
panel when the Gocator is running. Any measurements that are added and configured on the Measure
