Abstract:
1. An image-based occupancy sensor, comprising: a motion detection module that receives an image signal of a monitored volume comprising a sequence of image frames and processes the image signal to generate a motion detection signal; a people detection module that receives the image signal and processes the image signal to generate a people detection signal; a face detection module that receives the image signal and processes the image signal to generate a face detection signal; and a sensor integration module that receives the motion detection signal, the people detection signal, and the face detection signal, and generates an occupancy signal using the motion detection signal, the people detection signal, and the face detection signal, wherein the occupancy signal corresponds to an occupancy determination indicating vacancy or occupancy, wherein the occupancy determination indicating occupancy corresponds to the detection of one or more people within the monitored volume.
