Video stream and scene requirements for the Object Tracker tracker and its sub-tools

Note
titleAttention!

The Abandoned Object detection object detector can operate only with the Object Trackertracker detection tooldetector.

Before you create and configure the Abandoned Object detectionobject detector, do the following:

  1. Create the Object Trackertracker detection tool detector and set its general parameters (see Configuring the Object Trackertracker).
  2. Configure some parameters of the Object Tracker detection tool detector as follows:
    ParameterValueDescription
    Auto sensitivityYesIf auto sensitivity is enabled, sensitivity adjustments for moving and abandoned objects are not applied. To apply manual sensitivity adjustments, it is necessary to disable the auto sensitivity
    Long-time abandoned object detectionYesIf you enable this and the Enable filter parameter (see Configuring the Object Trackertracker), it can reduce the number of false positives during detection
    Abandoned object detectionYesObjects abandoned for 10 seconds or longer will be detected
    Alarm on object's max. idle time in area60

    Specify the time in seconds—if the object remains idle for the time longer than the specified, it will be detected. This value must be in the range [15, 1800].

    Info
    titleNote

    This parameter is used only for the Long-time abandoned object detection. It is recommended to select the parameter value starting from 15.


    Abandoned object detection sensitivity20

    For this parameter to work, it is necessary to first disable the Auto sensitivity parameter.

    Set the sensitivity for abandoned object detection detector and long-time abandoned object detection in the range [1, 100].

    Info
    titleNote

    This parameter depends on the lighting conditions and must be chosen empirically. It is recommended to select the parameter value starting from 20.


  3. Save the detection tool detector parameters by clicking the Apply button.

To create the Abandoned object detection detector, below the Object Tracker detection tool detector, click Create... → Abandoned Object.

By default, the detection tool detector is enabled and set to detect brought and abandoned objects.

If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:

ParameterValueDescription
Other
EnableYesBy default, the detection tool detector is enabled. To disable, select the No value
No
NameAbandoned Object
Enter a detection tool detector name or leave the default name
TypeAbandoned ObjectDetection tool Detector type name (non-editable field)
Basic settings
Maximum object height100

Set the maximum height of the object that must generate an event from the detection tooldetector, as a percentage of the frame size. The value must be in the range [0.05, 100]

Maximum object width100Set the maximum width of the object that must generate an event from the detection tool detector, as a percentage of the frame size. The value must be in the range [0.05, 100]
Minimum object height0,1Set the minimum height of the object that must generate an event from the detection tooldetector, as a percentage of the frame size. The value must be in the range [0.05, 100]
Minimum object width0,1Set the minimum width of the object that must generate an event from the detection tooldetector, as a percentage of the frame size. The value must be in the range [0.05, 100]
Note
titleAttention!

In the settings of the Object Tracker detection tool detector and the Abandoned Objectobject sub-tool, the values of the maximum and minimum height and width of the object must be equal.

Object type

Any

Select this value if it is necessary to detect both taken and abandoned objects

Abandoned

Select a value if it is necessary to detect an object that has disappeared from the monitored area and crossed its borders

Taken

To save the parameters of the detection tooldetector, click the Apply  button. To cancel the changes, click the Cancel  button.

The Abandoned Object detection object detector is now configured.
