Focusing Parameters
View Angle
View angle is determined by PackTrack calibration. This value represents the view angle of the
camera. This value should not be changed after it is set by PackTrack calibration.
This parameter allows defining the reading angle of the camera. For standard installations this
angle should be set to match the mechanical mounting: +15 or
‐ 15 degrees (single side object
reading), +45 degrees for a side/back read or ‐ 45 degrees for a side/front read (double side
object reading) depending on the type of installation. This parameter may be up to two
degrees different then the 15/45 degree after the completed calibration.
For top read single side, +15 degrees is facing downstream, and ‐ 15 degrees is facing upstream.
For top read multi ‐ side, +45 degrees for top/back and ‐ 45 degrees for top/front.
Positive angles correspond to the package front or leading side with respect to the package
movement and negative angles correspond to the package back or trailing side.
This field is automatically filled in during the static calibration of the unit (Calibration Wizard).
The possible values are from ‐ 50° to +50°. The default setting is 15°. See “Mounting and
Positioning AV500” on page 32.
Distance to Trigger Source (X)
Defines the distance from the camera scan line to the trigger source (typically a Photo Sensor,
Position Sensor, Light Curtain or DM3610 Dimensioner).
This field is automatically filled in during the static calibration of the unit (Calibration Wizard).
Far Working Distance (Z)
Defines the distance from the camera to the furthest scanning point.
This field is automatically filled in during the static calibration of the unit (Calibration Wizard).
