Methods and systems for identifying the crossing of a virtual barrier
First Claim
Patent Images
1. A method of identifying the crossing of a virtual barrier, the method being performed by a computerized monitoring system and comprising:
- receiving image data for a room from one or more 3D motion sensors;
configuring a virtual barrier within the room;
classifying an object within the room as a person;
creating a bounding box to circumscribe at least a portion of the person;
monitoring a position of the bounding box over time and relative to the virtual barrier; and
wherein upon detecting that at least a portion of the bounding box has touched or crossed the virtual barrier, initiating skeletal tracking, blob tracking, or a combination thereof to confirm the touching or crossing of the virtual barrier.

Abstract
Systems, methods and media are disclosed for identifying the crossing of a virtual barrier. A person in a 3D image of a room may be circumscribed by a bounding box. The position of the bounding box may be monitored over time, relative to the virtual barrier. If the bounding box touches or crosses the virtual barrier, an alert may be sent to the person being monitored, a caregiver or a clinician.

9. A system for identifying the crossing of a virtual barrier, the system comprising:
-
a computerized monitoring system in communication with one or more 3D motion sensors; and a computerized communication system; wherein the computerized monitoring system is configured to; receive image data from the one or more 3D motion sensors; configure a virtual barrier; analyze the image data to create a bounding box around a person in the image data; upon detecting that at least a portion of the bounding box has touched or crossed the virtual barrier, initiate skeletal tracking, blob tracking, or a combination thereof to confirm the touching or crossing of the virtual barrier; and send an alert to the computerized communication system upon confirmation of the touching or crossing of the virtual barrier. - View Dependent Claims (10, 11, 12, 13, 14)

15. Non-transitory computer-readable media having embodied thereon instructions which, when executed by a computer processor, cause the processor to:
-
receive image data for a room from one or more 3D motion sensors; configure a virtual barrier within the room, by a computerized monitoring system; classify an object within the room as a person; create a bounding box to circumscribe at least a portion of the person; monitor a position of the bounding box over time and relative to the virtual barrier; and wherein upon detecting that at least a portion of the bounding box has touched or crossed the virtual barrier, initiate skeletal tracking, blob tracking, or a combination thereof to confirm the crossing of the virtual barrier. - View Dependent Claims (16, 17, 18, 19)
