AI Technical Summary

Problems solved by technology

For example, multiple camera sensors with overlapping fields of view could each count the same entity, which could cause occupant totals to exceed the actual number of occupants
Because the sensors may not have completely overlapping fields of view, counting using only one of the sensors may result in a total of occupants that is less than the actual number of occupants
Therefore, while a single image sensor can count objects or people in their own field of view, multiple image sensors looking at the same area can lead to false counts of objects and / or people

Abstract

A system for determining occupancy includes a first luminaire with a first camera for detecting a first occupant and a second luminaire with a second camera for detecting a second occupant. The system also includes a processor for determining whether the first camera and the second camera have a common field of view, and responsive to determining that the first camera and the second camera have a common field of view to determine whether the first occupant and the second occupant are the same occupant.

Description

[0001] related application [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 62 / 264,132, filed December 7, 2015, entitled "Occupancy Detection," the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to occupancy detection, and more particularly to improving the accuracy of occupant count detection. Background technique [0004] LED solid-state illuminators provide a broad, unified, powered electronics platform for the integration of sensing devices such as image sensors (eg, cameras). Sensors can be used not only to view and track activity, but also to confirm occupancy. That is, sensors can be used to confirm the presence of one or more occupants in a space and the number of occupants in said space - regardless of occupancy / unoccupancy and number of occupants. While some image sensors can identify and count, for example, humans and / or ...
