6.2.7 Crowd Gathering Estimation
The crowd gathering function monitors a defined area, typically in outdoor scenes, for a set
number of people gathering and remaining inside the defined area. The size of the defined
area determines the minimum number of people that have to be present in the area before the
function triggers an alarm. Draw the defined area based on the relative height and width of a
person in the scene. For example, if the function should trigger an alarm if ten people gather in
a specified location, then estimate the relative height and width of a person in the scene and
draw the area that is ten times the height and ten times the width of a person.
Note that this function is susceptible to false alarms from continuously moving objects, such as
leaves and shadows, vehicle traffic, and people flow. Draw the monitoring area away from
these objects. Use this function for large outdoor areas, it is not recommended for close-range
analysis.
