Configuring the parameters

To create the Handrail holding detector, do the following:

  1. Create the Human pose detector (see Configuring the Human pose detector).
  2. Below the Human pose detector, click Create… → Handrail holding detector.

The Handrail holding detector generates an event if there is a person in the specified area of the frame who doesn't hold on to any of the specified handrails.

If necessary, you can change the detector parameters. The list of parameters is given in the table:

ParameterValueDescription
Other
EnableYesThe detector is enabled by default. To disable the detector, select the No value
No
NameHandrail holding detectorEnter the detector name or leave the default name
TypeHandrail holding detectorName of the detector type (non-editable field)
Basic settings
Number of measurements in a row to trigger detection2Specify the minimum number of frames with the corresponding pose or behavior for the detector to generate an event. The value must be in the range [1, 20].
The recommended (default) value is 2.
Increasing the value can help eliminate false events, but increases the risk of skips. 
Decreasing the value can help reduce skips, but increases the probability of false events

To save the parameters of the detector, click the Apply  button. To cancel the changes, click the Cancel  button.

Configuring the detection area

To configure the detection area of the Handrail holding detector, do the following:

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

      Using the Handrail line, specify one or several handrails in the frame.
  2. Using the anchor points of the Staircase zone, specify the zone in which a person must hold on to the handrail.
  • For convenience of configuration, you can "freeze" the frame. Click the  button. To cancel the action, click this button again.
  • The detection area is displayed by default. To hide it, click the  button. To cancel the action, click this button again.
  • To delete a line, click the  button.

Connfiguration of the Handrail holding detector is complete.
