The Person location tracker software module is configured on the settings panel of the Person location tracker object. This object is created on the basis of the Camera object on the Hardware tab of the System settings dialog window.

The Person location tracker software module is configured as follows:

  1. Go to the settings panel of the Person location tracker object.
  2. Set the Show objects on image checkbox, if it is necessary to highlight the detected object with a frame when viewing live video.

  3. From the Device drop-down list, select the device on which the neural network will operate. Auto—device is selected automatically: NVIDIA GPU gets the highest priority, followed by Intel GPU, then CPU.

    Attention!


  4. If you want to use a unique neural network, in the Tracking model field, click the button. In the opened standard Windows Explorer window, specify the neural network file. If you leave the field blank, the default networks will be used. They are selected automatically depending on the selected device.

  5. In the Frames processed per second [0.016, 100] field, set the number of frames per second that will be processed by the detection tool.

    Attention!

    For the scenes with static people, the FPS value must be at least 2. For the scenes with moving people—at least 4.

    The larger this value, the higher the accuracy of pose detection, but the greater the CPU load. With FPS=1, the accuracy will be no less than 70%.

    This parameter varies depending on the object speed of movement. To solve typical tasks, FPS value from 3 to 20 is sufficient. Examples:

    • pose detection for moderately moving objects (without sudden movements)—FPS=3;
    • pose detection for moving objects—FPS=12.
  6. In the Track retention time (sec) field, specify the time in seconds in the range from 0.3 to 1000 after which the object track is considered lost. This parameter is useful in situations when one object in the frame temporarily overlaps another.

    Note

    If an object (track) is close to the frame border, then approximately half the time specified in the Track retention time (sec) field must elapse from the moment the object disappears from the frame until its track is deleted.

  7. Click the Settings button. As a result, the Detection settings window opens.

    1. Click the Stop video button (1) to capture a frame.

    2. Click the Area of interest button (2) and specify the area in which the Person location tracker will operate (3). The specified area is highlighted with a red frame.

      Note

      To delete the selected area, click the button.

    3. Click the OK button (4) to save the settings of the detection tool.

  8. Click the Apply button on the settings panel of the Person location tracker object

  9. Configure the Pose detection (see Configuring the Pose detection), the Shooter detection (see Configuring the Shooter detection), or the Handrail grip detection (see Configuring the Handrail grip detection).

Configuration of the Person location tracker software module is complete.
