Abstract
System and techniques for an occupancy sensor are described herein. Images from a camera can be received. Here, the camera has a certain a field of view. A proximity indicator from a proximity detector can be received when an object enters the field of view. The images from the camera are processed to provide an occupancy indication. A first technique is used for the occupancy indication in the absence of the proximity indicator and a second technique is used otherwise.
Claims20
A device comprising:
- a camera with a field of view;
- a proximity detector arranged to detect an object in the field of view, the proximity detector being separate from the camera, and a sensing area of the proximity detector overlapping with the field of view of the camera;
- and
- a controller to:
- receive images from the camera;
- receive a proximity indicator from the proximity detector;
- and
- process the images from the camera to provide an occupancy indication, wherein a first occupancy detection technique is used in the absence of the proximity indicator and a second occupancy detection technique is used otherwise.
A non-transitory machine-readable medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:
- receiving images from a camera, the camera having a field of view;
- receiving a proximity indicator from a proximity detector, the proximity detector arranged to detect an object in the field of view, wherein the proximity detector is separate from the camera and a sensing area of the proximity detector overlaps with the field of view of the camera;
- and
- processing the images from the camera to provide an occupancy indication, wherein a first occupancy detection technique is used in the absence of the proximity indicator and a second occupancy detection technique is used otherwise.
