Metric( cm)

Observe several people as they pass through the field of view and verify that the camera reports reasonable heights for all
individuals.
NOTE
The average height for women is 162 cm (64 inches) and average height for men is 176 cm (69 inches). As people move off
the edge of the camera, their height will be reported based on what the camera can see of the person. Heights should be the
most accurate when people are direct under the camera.

If the height numbers are reasonable, continue to the next section. If the numbers are not reasonable, re-calibrate the
camera, then re-verify the calibration using this procedure.
4.4 Setting Object Filtering Options
The Calibration tab also contains track filtering options. These options allow you to configure the DIGIOP® 3D camera to eliminate
tracks created from shopping carts and to ignore tracks that are below a certain height.
By default, the camera will count any object that exceeds 120 cm (4 feet) in height. If you want to track shorter objects (shopping
trolleys, children, strollers, etc.), you can change the Height Filter setting on the Calibration page.
