Dual Sensor Layout
For dual sensor (Buddy) systems it is necessary to specify the relative mounting orientations of the
sensors. This information allows the Alignment or Travel Calibration procedures to determine the correct
system-wide coordinates for laser profiling and measurements. Refer to the Coordinate Systems (page
40) in this chapter for more information on sensor and system coordinates.
To specify the layout, navigate to the Layout Panel on the Setup Page:
Supported Orientations
Orientation Example
None
Each sensor operates as an isolated device. Measurements are
reported in a separate coordinate system for each sensor.
Wide
Sensors are mounted in Left (Main) or Right (Buddy) positions for a
larger combined field of view.
Staggered
Sensors are mounted in Before (Main) or After (Buddy) positions
along a conveyor belt for measurements before and after a
manufacturing process.
Note that Travel Calibration is required for Staggered systems.
Opposite
Sensors are mounted in Top (Main) or Bottom (Buddy) positions
for a larger combined field of view and the ability to perform Top/
Bottom differential measurements.
Overlap
If the Main and Buddy sensors are mounted such that the camera from one sensor can detect the laser
from the other sensor, then the Overlap feature can be used to eliminate laser interference. Overlap
creates a time offset for laser exposures and ensures that interfering lasers are not strobed at the same
time. Use of the overlap feature reduces the maximum camera speed.
