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.
Claims20
A computerized 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 according to a predetermined confidence level that is based on a risk tolerance level, wherein the predetermined confidence level indicates a threshold confidence in classifying the object within the room as a person to create the bounding box;
- and
- monitoring a position of the bounding box over time and relative to the virtual barrier.
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 detect a person and create a bounding box around at least a portion of the person in the image data according to a predetermined confidence level that is based on a risk tolerance level, wherein the predetermined confidence level indicates a threshold confidence in detecting the person to create the bounding box;
- and
- send an alert to the computerized communication system upon detecting that the bounding box touched or crossed the virtual barrier.
Non-transitory computer-readable media having embodied thereon instructions that, 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;
- classify an object within the room as a person;
- create a bounding box to circumscribe at least a portion of the person according to a predetermined confidence level that is based on a risk tolerance level, wherein the predetermined confidence level indicates a threshold confidence in classifying the object within the room as a person to create the bounding box;
- and
- monitor a position of the bounding box over time and relative to the virtual barrier.
