The Perspective enhances detection tools performance and helps evaluate real sizes of objects based on simplified calibration system.

To configure the perspective, do the following:

1. Select the Object tracker object and click the button.

2. Set the size of the same object in different areas of the field of view. To create a calibration length, left-click within the video image in the viewing tile and add two anchor points. Set at least three calibration lengths. You can resize the length by stretching its anchor points . You can move it on screen by dragging and dropping.
   

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

   
   

   To delete it, click the button.

   
   

3. Select Yes in the Object calibration option (1).
   

4. Enter the height in decimeters of the object you want to find in the Leveling rod height field (2).

   Objects smaller than the specified value will not be detected.

   
   

5. Click the Apply button.

Perspective is now configured.
