Calibrating the Counting Line
To generate accurate counts, the counting line requires calibration. Unlike VCAsurveillance, this cannot
be performed at a general level for the whole scene using the 3D calibration tool. This is because the
counting line is not always placed on the ground plane: it may be placed at any orientation at any location
in the scene. For example, a counting line could be configured vertically with a side-on camera view.
Instead of the 3D calibration tool, the counting line has its own calibration setting. Two bars equidistant
from the center of the line represent the width of the expected object. This allows the counting line to
reject noise and 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 image 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
Shadow Filter
The counting line features a shadow filter which is designed to remove the effects of object shadows
affecting the counting algorithm. Shadows can cause inaccurate counting results by making an object
appear larger than its true size or by joining two or more objects together. If shadows are causing
inaccurate counting, the shadow filter should be enabled by selecting the "Shadow Filter" check box for
the line. It is recommended that the shadow filter only be enabled when shadows are present because
the algorithm can mistake certain parts of an object for shadows and this may lead to worse counting
results.
