Abstract

Devices, methods, and systems for occupancy detection are described herein. One device includes instructions to receive an image of a portion of a facility captured by an imaging device, the image defined by a field of view, and set a first occupancy detection threshold for a first part of the field of view and a second occupancy detection threshold for a second part of the field of view.

First claim

What is claimed:

1. A non-transitory computer-readable medium having instructions stored thereon that when executed by one or more processors cause the one or more processors to:
receive one or more images captured by an imaging device having a field of view;
display the one or more received images on a display;
receive a first user input to define at least part of a first region of non-interest on one or more of the received images, wherein the first region of non-interest includes only a portion of the field of view of the imaging device and is defined by one or more boundary vertices;
receive a second user input to select and reposition one or more of the boundary vertices of the first region of non-interest to redefine the first region of non-interest;
ignore any motion in the field of view of the imaging device that occurs inside of the first region of non-interest; and
provide a motion alert when motion is detected in the field of view of the imaging device that occurs outside of the first region of non-interest.

2. The non-transitory computer-readable medium of claim 1 , wherein the instructions cause the one or more processors to:
receive a third user input to define at least part of a second region of non-interest on one or more of the received images, wherein the second region of non-interest includes only a portion of the field of view of the imaging device and is defined by one or more boundary vertices;
receive a fourth user input to select and reposition one or more of the boundary vertices of the second region of non-interest to redefine the second region of non-interest;
ignore any motion in the field of view of the imaging device that occurs inside of the second region of non-interest; and
provide a motion alert when motion is detected in the field of view of the imaging device that occurs outside of the second region of non-interest and outside of the first region of non-interest.

3. The non-transitory computer-readable medium of claim 2 , wherein the second region of non-interest does not overlap the first region of non-interest.

4. The non-transitory computer-readable medium of claim 1 , wherein the instructions cause the one or more processors to:
detect one or more movement patterns captured by the imaging device; and
automatically define at least part of the first region of non-interest based at least in part on at least one of the one or more detected movement patterns.

5. The non-transitory computer-readable medium of claim 1 , wherein the instructions cause the one or more processors to:
detect an edge of an object captured by the imaging device; and
automatically define at least part of the first region of non-interest based at least in part on the detected edge.

6. The non-transitory computer-readable medium of claim 1 , wherein the first user input includes drawing a free-form area that defines at least part of the first region of non-interest.

7. The non-transitory computer-readable medium of claim 1 , wherein one or more images captured by the imaging device include infrared images.

8. The non-transitory computer-readable medium of claim 1 , wherein the first region of non-interest is highlighted using a particular color, gradient and/or line style superimposed on one or more of the images captured by the imaging device.

9. The non-transitory computer-readable medium of claim 1 , wherein the imaging device is a video camera that captures visible images and infrared images, and movement is detected in both of the visible images and the infrared images.

10. The non-transitory computer-readable medium of claim 1 , wherein the display and/or one or more of the processors are part of a smart phone.

11. The non-transitory computer-readable medium of claim 1 , wherein the instructions are part of an application program that is downloadable to a computing device that includes one or more of the processors.

12. A method comprising:
receiving one or more images captured by an imaging device having a field of view;
identifying a moving object in the field of view of the imaging device;
identifying when the moving object enters an occluded area in the field of view of the imaging device that is occluded by an occluding object, wherein when the object is in the occluded area, the object is occluded from the field of view of the imaging device by the occluding object;
waiting for the object to exit the occluded area for at least a predetermined period of time; and
after waiting for the object to exit the occluded area for at least the predetermined period of time, taking one or more predefined actions.

13. The method of claim 12 , wherein the object has object edges, and wherein the method comprises determining that the object enters the occluded area when the object disappears from one of the object edges.

14. The method of claim 12 , wherein the object has object edges, and wherein the method comprises:
determining an object speed of the moving object; and
determining that the object enters the occluded area when the object disappears from one of the object edges at a rate that is consistent with the object speed.

15. The method of claim 12 , wherein taking one or more predefined actions comprises one or more of deactivating lighting in a room that includes the field of view and activating a security system in a room that includes the field of view.

16. A system for detecting motion events in a monitored area, the system comprising:
an imaging device having a field of view for capturing a plurality of images of the monitored area;
a mobile device having a touch screen display;
a computing device operatively coupled to the imaging device and the mobile device, the computing device configured to:
receive a plurality of images captured by the imaging device;
send one or more of the received images for display on the touch screen display of the mobile device;
receive from the mobile device a first user input entered via the touch screen display of the mobile device that defines at least part of a first region of non-interest on one or more of the images displayed on the touch screen display of the mobile device, wherein the first region of non-interest includes only a portion of the field of view of the imaging device and is defined by one or more boundary vertices;
receive from the mobile device a second user input entered via the touch screen display of the mobile device that selects and reposition one or more of the boundary vertices of the first region of non-interest to redefine the first region of non-interest;
ignore any motion in the field of view of the imaging device that occurs inside of the first region of non-interest; and
provide a motion alert when motion is detected in the field of view of the imaging device that occurs outside of the first region of non-interest.

17. The system of claim 16 , wherein the computing device is further configured to:
detect one or more movement patterns captured by the imaging device; and
automatically define at least part of the first region of non-interest based at least in part on at least one of the one or more detected movement patterns.

18. The system of claim 16 , wherein the computing device is further configured to:
detect an edge of an object captured by the imaging device; and
automatically define at least part of the first region of non-interest based at least in part on the detected edge.

19. The system of claim 16 , wherein the first user input entered via the touch screen display of the mobile device includes drawi
