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

Note
titleAttention!

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

Before you create and configure the Abandoned object detection detector, do the following:

  1. Create the Object tracker 
    2. detection tool
  2. detector and set its general parameters (see Configuring the Object
    3. Tracker
  3. tracker).
  4. Configure some parameters of the Object
    5. Tracker detection tool
  5. tracker 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
    6. Tracker
  6. tracker), 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

    7. should

  7. 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

    8. detection

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

    Info
    titleNote

    This parameter depends on the lighting conditions and

    9. should

  9. must be chosen empirically. It is recommended to select the parameter value starting from 20.

  10. Save the
    11. detection tool
  11. detector parameters by clicking the Apply Image Modified button.

To create the Abandoned object detection detector, below the Object Tracker detection tooltracker 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:

Basic settings
Maximum object height100

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

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

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

Object type


Any

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

AbandonedBrought

Select a value if it is necessary to detect an object that has disappeared from the

observed

monitored area and crossed its

boundaries
Abandoned

borders

TakenAnySelect this value if it is necessary to detect both brought and abandoned objects

By default, the entire frame is a detection area.  If If necessary, in the preview window, set detection areas with the help of anchor points Image Removed you can reduce the detection area (see Configuring a detection area) and/or set one or more skip areas (see Configuring a detection skip area).

Info
titleNote
  • For convenience of configuration, you can "freeze" the frame. Click the Image Modified button. To cancel the action, click this button again.
  • The detection area is displayed by default. To hide it, click the Image Modified button. To cancel the action, click this button again.

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

The Abandoned object detection Abandoned object detector is now configured.
