Setting up common parameters for Pose detection tools

By default, the Close-standing people detection tool triggers when "skeleton" bounding boxes around individuals collide. 

Note

Bounding boxes are not displayed in the interface. They are usually a bit larger than the "skeletons" dimensions.

You can set another triggering distance by adjusting the frame perspective:

Attention!

For portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, etc.) perspective adjustment is a must.

  1. Select a detection tool, and click the button in the preview window.

  2. Set the size of the same object in different areas of the frame. To create a leveling rod, left-click on the video image and add two anchor points. Set at least three leveling rods. The size of the leveling rod should be about the average height of a person at this point in the frame. You can resize the rod by stretching its anchor points . You can move it on screen by dragging and dropping.

    Attention!

    When setting up the leveling rods, the following conditions should be met:

    1. The rods that are located at the same distance from the video camera lens, should be of the same size.
    2. The feet of the rods should be located on the same surface (e.g. floor).

    3. In complex scenes, it is recommended to add more than three rods to increase the accuracy of the detection.

    4. In the parts of the frame where the lens vertical distortion is observed, the rods should be parallel to the nearest vertical objects (e.g. door, wardrobe).

    Attention!

    For portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, etc.), the arrangement of the rods should form triangles.

    Note

     For your convenience, you can click the button and configure the mask on a still frame. To undo, click this button again.

    Note

    To delete the rod, click the button.

  3. In the Distance sensitivity field (1) enter a triggering distance value in meters between people. The detection tool will trigger if the distance between people in the frame becomes equal or less than the specified value. The value should be in the range [0; 20].

  4. In the Leveling rod length field (2) enter the average height of a person (in meters), according to which the leveling rods are set. The value should be in the range [0; 3].

  5. Set the minimum number of frames in which the detection tool should detect close-standing people in order to trigger (3). The value should be in the range [1; 100].

Configuring the frame perspective for the Close-standing people detection tool is complete.
