In the drop-down menu, select the Laser Trigger, then click Add.
CONFIGURE LASER TRIGGER
An algorithm filters and separates measured raw distance data into background and foreground
(vehicle), latter constituting a trigger event.
Background is calculated during a calibration phase lasting a couple of seconds. Apart from the
common trigger parameters (edge/level mode, offsets), this trigger source has no tuneable
properties.
To achieve the proper settings, go to Live view / Extensions menu, activate Image Center function to
see the direction of the laser trigger.
Based on measurements, we can say that 20 meters is the max. distance where it works properly.
Calibration can be triggered manually by pushing the Calibrate button. The current background
distance is shown in the Reference distance field. Raw, unfiltered data is shown in the Current
distance field in meters. It is normal (and taken care by the algorithm) that this value jitters
somewhat.
The Trigger health works effectively above 90%, below this value it must be reconfigured!
