Occupant tracking
First Claim
1. A lighting fixture comprising:
- a communication interface;
a light source configured to provide light output for general illumination;
an image sensor configured to capture image information associated with a field of view; and
control circuitry associated with the light source and the image sensor and configured to;
provide a drive signal to the light source to control the light output;
for each object in the field of view;
determine if an object in the field of view is an occupant based on the image information; and
if the object is the occupant, track movement of the occupant within the field of view;
determine a number of occupants in the field of view; and
provide occupancy information bearing on the number of occupants in the field of view to a remote entity via the communication interface.

Abstract
A lighting fixture has a communication interface; a light source configured to provide light output for general illumination; an image sensor configured to capture image information associated of with a field of view; and control circuitry, which is configured to provide a drive signal to the light source to control the light output. In one embodiment, the control circuitry is further configured to, for each object in the field of view, determine if an object in the field of view is an occupant based on the image information; if the object is an occupant, track movement of the occupant within the field of view; and determine a number of occupants in the field of view. The control circuitry may also be configured to provide occupancy information bearing on the number of occupants in the field of view to a remote entity via the communication interface.
