Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 154
The following settings can be tuned to improve the accuracy and reliability of part detection.
Setting Description
Height Threshold
Determines the profile height threshold for part detection. The setting for Threshold
Direction determines if parts should be detected above or below the threshold. Above is
typically used to prevent the belt surface from being detected as a part when scanning
objects on a conveyor.
In an Opposite layout, the threshold is applied to the difference between the top and the
bottom profile.A target thinner than the threshold value is ignored, including places
where only one of either top or bottom is detected.
To separate parts by gated external input, set the Height Threshold to the active area Z
offset (i.e., minimum Z position of the current active area), set Source to Time or
Encoder and check the Gate on External Input checkbox in the Trigger panel (page
117).
Include one-sided data
The option is only displayed with dual-sensor systems in Opposite layout. or multi-
sensor systems in Grid layout with at least one sensor in the Bottom row. When the
option is disabled, data points from a sensor are excluded if the points directly opposite
from the other sensor are missing (due to occlusions, drop-outs, and so on). When the
option is enabled, data points are included even if data points from the other sensor are
missing.
