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, wardrobe);
for portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, and so on), the arrangement of the rods must form triangles.
