Configuring the pose detection

The pose detection is configured as follows:

1. Go to the Pose detection object settings panel, which is created on the basis of the Person location tracker object.
   

2. Specify the perspective on the video image on which the human location will be detected:

   1. Click the Settings button (1). As a result, the Detection settings window will open.
      
      

   2. Click the Stop video button (1) to capture the video image.

   3. Specify the size of the same human at least in three different parts of the frame (2) with the calibration segments. To create a calibration segment, click and hold the left mouse button on the video image so that you can specify the necessary length size. You can change the size of the already created segments using nodes. The calibration segments should be located at different angles to each other depending on the scene and the distortion of the video image.
      

      Note

      To delete the created segment, click thebutton (3).
   4. Click OK (4).
3. Set the Trigger an alarm on camera checkbox (2) if it is also necessary to trigger an alarm on the camera by the specified pose detection.
4. In the Number of frames for decision making (1-20) field (3), enter the required amount of frames from 1 to 20 on which the human should be found in the specified pose to trigger the corresponding event.

5. From the Type drop-down list (4), select the human type which is necessary to detect:

   • Sitting person detection — the detection triggers when a sitting human is found in the frame.

   • Recumbent person detection — the detection triggers when a recumbent human is found in the frame.

   • Hands up detection — the detection triggers when a human with hands raised is found in the frame. The hand is considered to be raised if the forearm is parallel to the backbone. If this type is selected, the following additional settings will become available:
     

     • Working mode — sets the hands position at which the alarm event will be generated.

   • Active shooter detection — the detection triggers when a human reaching his/her hand forward parallel to the ground is found in the frame. 

   • Person detection — the detection triggers when any pose of a human is found in the frame.

   • Close-standing people detection — the detection triggers if the distance between two people is less than specified. If this type is selected, the following additional settings will become available:
     
     • Calibration column length [0, 3] — sets the length of the calibration segments, which were set when adjusting the perspective of the video image, from 0 to 3 meters.
     • Distance sensitivity [0, 20] — sets the minimum distance between people from 0 to 20 meters. If the distance between people in the frame is equal to or less than the specified one, then the detection will be triggered.
     • Number of people to alert [2, 20] — sets the number of people who should break the distance for the detection to be triggered. Possible values: from 2 to 20.
6. Click the Apply button (5).

The pose detection is now configured.
