Attention!

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

To configure Abandoned object detection, do as follows:

  1. Select the Object Tracker object (1).
  2. To enable the Abandoned object detection (2), select Yes for the corresponding parameter. 

    Note

    Objects abandoned for 10 seconds or longer will be detected.

  3. In the Abandoned object detection sensitivity field (3), set the sensitivity for Abandoned object detection (2) and Long-time abandoned object detection (6). This value should be in the range [1, 100].

    Note

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

  4. In the Alarm on object's max. idle time in area field (4) specify the time in seconds. If the object remains idle for the time longer than the specified, it will be detected. This value should be in the range [15, 1800].

    Note

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

  5. To enable the Auto sensitivity (5), select Yes for the corresponding parameter.

    Attention!

    If 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.

  6. To enable the Long-time abandoned object detection, select Yes for the corresponding parameter (6).

    Note

    If you enable the Long-time abandoned object detection parameter (6) and the Neural network filter (see 추적기 기반 장면 분석 검출 도구의 일반 매개변수 설정), it can reduce the number of false positives during detection.

  7. Under the Object Tracker object, create the Abandoned object object (see 검출 도구 생성).
  8. To enable the Abandoned object detection sub-tool, do the following:

    1. Select object class (2).

    2. Select object color (3).
    3. Select object type (4):

      • Taken—the object that disappeared from the observed area and crossed its borders will be detected.

      • Abandoned—the object that appeared in the observed area and crossed its borders will be detected.

      • Any—both taken and abandoned objects will be detected.

    4. Specify the maximum height and width of the object (5). The value should be in the range [0.05, 100].

    5. Specify the minimum height and width of the object (6). The value should be in the range [0.05, 100].

      Attention!

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

  9. Click the Apply button.

Abandoned object detection is now configured.
