Abstract

A counting system includes a counting apparatus, which includes a plurality of multi-sensor detectors configured to detect physical contact data and vertical range data corresponding to one or more steps across the multi-sensor detectors, and first circuitry configured to determine physical contact vectors and coordinate data from the physical contact data and the vertical range data. The counting system also includes at least one server including second circuitry configured to receive the physical contact vectors and the coordinate data from the counting apparatus, determine footprint patterns and body patterns based on the physical contact vectors and the coordinate data, and estimate a number of beings passing over the counting apparatus based on the footprint patterns and the body patterns.
