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.
2 NavigatetotheLayoutpanelandselectGlobalorCurrentConfigurationastheSource.
Click the arrow button next to Calibration to expand the panel.
3 Select Alignment Calibration as the Type.
4
Clear the previous calibration if present.
Press the Clear Calibration button to remove the existing calibration.
5
Select a calibration Target.
Select Flat Surface 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. Refer to
Installation (page 25) 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.
Alignment calibration uses the exposure defined for the single exposure mode, regardless of the
current exposure mode.
7
Use Range Mode to inspect calibration results.
Laser ranges 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,
these values can be manually entered if desired. Refer to Trigger Panel (page 65) for more information.
