belt, an internal software tachometer, or a PDG100 Speed Detector when using a
tilt-tray or cross-belt system.
• Height/Side Position Sensor: The focusing position is computed by the camera
based on the position of the parcel measured by a position sensor. The Datalogic
sensors may be a RangeFinder, DM3610 Dimensioner, or AREAscan™ DS2 Light
Array (LCC-75xx Light Curtain Kit) or S85.
•
Trigger Source: The camera needs to know when to acquire an object. In multiple
camera systems, each package has to be uniquely identified by all the cameras.
For this reason, all of the cameras in a reading station share a unique trigger
source.
All the sensors are connected to the Master camera that interprets the information and
dis
tributes it to the Slave cameras.
The start and stop of an acquisition are triggered by a start/stop event generated by the
trig
ger device (position sensor). The acquisition of a package doesn’t start when the
trigger source detects it, but with a certain delay depending on:
• the distance between the trigger device and the view line and the far distance of
the
view line for each AV7000 in the Array
• the view line angle (alpha) of the camera
• the speed of the object
Based on the AV7000 mounting position, the unit tries t
o acquire one (reading angle
alpha = 15°) or two faces of the parcel (alpha = +/-45°). The AV7000 can process a maxi-
mum package count of 64 bet
ween trigger and transmit.
Pulsed Illumination
When building multi-camera stations with standard continuous light illuminators, the
illumination areas must be accurately chosen to avoid the illuminator of one camera
disturbing the acquisition of another camera. In particular the lobes of the side camera
illuminators must not cross over the conveyor belt. This constraint leads to long multi-
sided reading stations.
In Pulsed Illumination systems, all the cameras are synchronized so cameras with cross-
ing illuminator lobes are not illuminating simultaneously. Using pulsed illumination, the
side
cameras’ illumination lobes can cross on the conveyor and the reading station
dimensions can be greatly reduced.
