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. Bounding box tracking may be used in addition to or instead of an initial tracking process, such as skeletal tracking.
Claims20
A computerized method of monitoring an individual, the computerized method being performed by a computerized monitoring system and comprising:
- receiving, from one or more 3D motion sensors, image data of a room to be monitored;
- configuring a virtual barrier within the room;
- utilizing skeletal tracking to initially track a position of a person detected within the room to determine whether the person touches or crosses the virtual barrier;
- and
- switching from skeletal tracking to bounding box tracking to track the position of the person to determine whether the person touches or crosses the virtual barrier, wherein bounding box tracking includes monitoring a position of a bounding box circumscribing at least a portion of the person relative to the virtual barrier.
A system for monitoring an individual, 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, from one or more 3D motion sensors, image data of a room to be monitored;
- configure a virtual barrier within the room;
- utilize skeletal tracking to initially track a position of a person detected within the room to determine whether the person touches or crosses the virtual barrier;
- and
- switch from skeletal tracking to bounding box tracking to track the position of the person to determine whether the person touches or crosses the virtual barrier, wherein bounding box tracking includes monitoring a position of a bounding box circumscribing at least a portion of the person relative to the virtual barrier.
Non-transitory computer-readable media having embodied thereon instructions that, when executed by a computer processor, cause the computer processor to:
- receive, from one or more 3D motion sensors, image data of a room to be monitored;
- configure a virtual barrier within the room;
- utilize skeletal tracking to initially track a position of a person detected within the room to determine whether the person touches or crosses the virtual barrier;
- and
- switch from skeletal tracking to bounding box tracking to track the position of the person to determine whether the person touches or crosses the virtual barrier, wherein bounding box tracking includes monitoring a position of a bounding box circumscribing at least a portion of the person relative to the virtual barrier.
