To configure the Handrail holding detection tool, do the following:

1. Set common parameters (see Setting up common parameters for Pose detection tools).
2. Click anywhere in the Preview window.

3. Mark one or several handrails with lines (1).
   
   

   If lens distortion makes the handrail non-linear, use several lines. The presence of a person in the staircase zone is determined by their lower limbs.

   
   

4. Set anchor points to specify the area where a person should hold the handrail (2).
    

Configuring the Handrail holding detection tool is complete.
