3. Select Leveling rod.
   
4. Specify the size of the same person in different parts of the frame by eye:  
   • To create a leveling rod, left-click the video image to add two anchor points.

   • Set at least three calibration rods. The lower anchor points of any three rods must not be located on the same line (horizontal, vertical, slanting, and so on).

   • The size of the leveling rod must be about the average height of a person at this part of the frame.
   • You can resize the rod by stretching its anchor points . You can move it on screen by dragging and dropping.
     
     

     Note
     title Attention!
     When you set up leveling rods, the following conditions must be met: the rods that are located at the same distance from the camera lens must be of the same size; the feet of the rods must be located on the same surface (for example, floor); in complex scenes, we recommend adding more than three rods to increase the accuracy of the detection; in the parts of the frame where the lens vertical distortion is observed, the rods must be parallel to the nearest vertical objects (for example, door or wardrobe); if you add only three leveling rods to a scene, you cannot remove them from the scene, you can resize them and change their location; if you add more than three leveling rods to a scene, you can resize them and change their location, and remove them from the scene; for portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, and so on), the arrangement of the rods must form triangles.
