Detecting unauthorized visitors
First Claim
1. A system for detecting unauthorized visitors, the system comprising:
- one or more 3D motion sensors located to provide the one or more 3D motion sensors with a view of a person and surrounding area to be monitored; and
a computerized monitoring system communicatively coupled to the one or more 3D motion sensors, the computerized monitoring system configured to;
utilize one or more images received from the one or more 3D motion sensors to identify the person being monitored;
detect when a visitor enters the view of the one or more 3D motion sensors;
receive a plurality of reference points on faces of registered visitors from a remote database;
using one or more images received from the one or more 3D motion sensors, determine whether the visitor is an unauthorized visitor by identifying a plurality of reference points on the face of the visitor and compare positions, distances between, sizes, or shapes of the reference points to positions, distances between, sizes, or shapes of the plurality of registered reference points on the faces of registered visitors;
initiate an alert being sent to one or more designated recipients; and
determine whether the unauthorized visitor made one or more corrective actions based on information received from the one or more 3D motion sensors after the alert is sent to one or more designated recipients.

Abstract
An unauthorized visitor system collects an image of a person detected in a room of a patient. The system identifies reference points on the person'"'"'s face, for example, points along the cheeks, jowls, and/or brow. The system may compare the reference points to reference points of images associated with registered visitors. The system then determines, based on the comparison, if the person is a registered visitor. One or more designated recipients may be alerted if the person is not a registered visitor or if the person breaches a patient identification zone established around a particular patient. The system may also register the person in a database of visitors.

11. A computerized method for detecting unauthorized visitors, the method implemented by one or more processors and comprising:
-
receiving, from one or more 3D motion sensors, an image of at least two persons detected in a room of an individual being monitored, wherein the at least two persons are detected using skeletal tracking; receiving a plurality of registered reference points on faces of registered visitors from a remote database; determining at least one person is an unauthorized visitor by identifying reference points on a face of the at least one person using information from the one or more 3D motion sensors and comparing positions, distances between, sizes, or shapes of the reference points to positions, distances between, sizes, or shapes of the plurality of registered reference points on the faces of registered visitors; upon determining the at least one person is an unauthorized visitor, initiating an alert being sent to one or more designated recipients; and determining whether the at least one person who is an unauthorized visitor made one or more corrective actions based on information received from the one or more 3D motion sensors after the alert is sent to one or more designated recipients. - View Dependent Claims (12, 13)

14. Non-transitory computer-readable storage media having embodied thereon instructions that, when executed by one or more computer processors, cause the one or more computer processors to:
-
receive, from one or more 3D motion sensors, a series of images of a person detected in a room of an individual being monitored; receive a plurality of registered reference points on faces of registered visitors from a remote database; determine that the person is an unauthorized visitor by identifying reference points on a face of the person using at least a portion of images from the series of images received from the one or more 3D motion sensors and comparing positions, distances between, sizes, or shapes of the reference points to positions, distances between, sizes, or shapes of the plurality of registered reference points on the faces of registered visitors; upon determining the person is an unauthorized visitor, initiate an alert being sent to one or more designated recipients; and determine whether the person who is an unauthorized visitor made one or more corrective actions based on information received from the one or more 3D motion sensors after the alert is sent to one or more designated recipients. - View Dependent Claims (15, 16, 17, 18)
