Instead of the 3D calibration tool, the counting line has its own calibration setting. Two bars equidistant from
the centre of the line represent the width of the expected object. This allows the counting line to reject noise
and also count multiple objects.
To calibrate the counting line:
 Select the counting line with the mouse.
 Check the "Width Calibration" box under the Counting Line rule in the property inspector.
 Use the mouse wheel or drag the calibration markers to adjust the distance between the calibration
markers until the distance is approximately the size of the objects to be counted.
 The calibration width is displayed on the property inspector under the counting line rule. The figure
which is displayed is the calibration width expressed as a percentage of the screen width. This figure
can also be edited to change the calibration width.
 The small markers on either side of the big markers indicate the minimum and maximum width which is
counted as a single object.
 Apply the settings.
4.4.2.7.5 Calibration Diagnostics Mode
To enable the user to more accurately configure the calibration for the counting line, there is a diagnostics
feature which can be enabled to provide feedback of the counting results. To enable this mode, select the
"Metadata Format" ->"Counting Line Diagnostics" on the VCA Advanced Settings page .
