Requirements and recommendations for the People Counting module🔗

Video stream🔗

Depending on the operation conditions, the frame rate must be as follows:

  • Several people in a frame: at least 10 fps;

  • Separately moving people in a frame: at least 15 fps.

Image🔗

  • For reducing false triggering due to the changes of the background and lighting, it is required to ensure uniform illumination without flicker and sharp changes of brightness. The presence of moving foreign objects in the camera field of view is to be avoided because such objects may also be counted.

Scene and camera position🔗

  • The camera must be installed vertically. A different way of camera installation may adversely affect the counting accuracy.

  • The recommended minimum camera installation height is 3 meters above the ground.

  • The camera must be fixed.

Warning

It is not recommended to place the cross line in the immediate proximity of doors or other moving objects.

Warning

If the Separately moving people in a frame option is used and there are moving foreign objects in the frame, including such objects as doors, escalators etc., it is recommended to specify the detection zone that does not include these objects in the software motion detector settings.

Object size🔗

To maximize the accuracy of the counting, it is important to properly configure the person size in the Eocortex Configurator application.

  • The minimum person size, depending on operating conditions:

    • Several people in a frame: at least 10% of the intersection line segment length.

    • Separately moving people in a frame: at least 80 pixels in height.
