Alignment Calibration
Alignment calibration can be used to compensate for mounting inaccuracies by aligning sensor data to
a common reference surface (often a conveyor belt).
To perform alignment calibration:
1 Ensure that all sensors have a clear view of the target surface.
Remove any irregular objects from the sensor's field of view that might interfere with alignment
calibration. If using a calibration bar for dual sensors (Buddy), ensure that the lasers are aligned with a
reference hole on the calibration bar.
2
Ensure that Trigger is set to Time.
Calibration can only be performed with Time-based triggering. Other trigger sources can be selected
again after calibration.
3
Navigate to the Calibration Panel and select Alignment Calibration.
4 Clear the previous calibration, if present.
Press the Clear Calibration Button to remove the existing calibration.
5 Select a calibration target.
Select None to use the conveyor surface (or other flat surface) as the calibration reference, or Bar to
use a custom calibration bar. If using a calibration bar, specify the bar dimensions and reference hole
layout. Refer to the Calibration Targets section (page 21) in this guide for more information.
6
Press the Calibrate Button.
The sensors will start and the alignment calibration process will take place. Calibration is performed
simultaneously for all sensors. If the sensors do not calibrate, check and adjust the exposure settings.
7 Use Profile Mode to inspect calibration results.
Laser profiles from all sensors should now be aligned to the calibration target surface.
The base of
the calibration target (or target surface) provides the origin for the system Z-axis.
Alignment calibration does not automatically calibrate the resolution of the encoder (if present). However,
the encoder resolution can be manually entered if desired. Refer to the Trigger section (page 46) for more
information.
