DIGIOP® 3D Camera User Manual
SECTION 1: OVERVIEW
The camera compares the person, child, and the shopping cart to the shape model of a shopping cart The cart is excluded from
counting because it does not exceed the Height Filter and because it matches the shape model of a cart. The child is filtered out as
well based on the height filter.

For more information on enabling cart filtering, see “Setting Object Filtering Options” later in this manual.
1.2.9 Tall Object Filtering
When filtering out tall objects, the DIGIOP® 3D camera uses an average height calculation, an estimate of the average height of an
object based on all mass that the camera determines to be part of the object. Because most people are generally within one height
range (100 cm – 80 cm) and most other objects (balloons, ladders, products, etc.) are above 180 cm. By default, the camera is
configured to filter out any object that has an average mass height above 180 cm. DIGIOP® recommends that you not change this
setting.
The camera begins tracking an object when the object exceeds the minimum tracking height. The colored boxes below show the
typical areas of a person that are tracked, and considered as part of the object mass, by a DIGIOP® 3D device. The DIGIOP® 3D camera
estimates the height of all mass contained in the green and blue boxes and calculates an average height. This average height is
always less than the actual height of the person. Once the DIGIOP® 3D camera calculates the average mass height of an object, it
compares the threshold set on the
