Facial recognition based monitoring systems and methods

摘要

A system to monitor patient position in bed and related methods of use are disclosed. The system to monitor patient position in bed relies on facial recognition and determination of the time spent by the patient in a particular position. Appropriate alarms and messages are displayed if the patient remains in a particular position for a time period greater than a predetermined threshold.

主权项

1. A system for monitoring a person, comprising:
a person support apparatus; a first image capture device arranged to capture an image in a first direction; a second image capture device arranged to capture an image in a second direction which differs from the first direction; a processor including instructions operable to cause the processor to process the captured images to carry out facial recognition on the captured images; a timer configured to communicate with the processor to track a time period or a number of iterations; and an alarm configured to be triggered by the processor; wherein the processor determines if a face has been present in an image captured by the first image capture device, and if the processor determines that the face is present in the image captured by the first image capture device, the timer tracks the time period or the number of iterations; if the processor determines a face is not present in the image captured by the first image capture device, the system acquires an image from the second image capture device to determine if a face has been present in an image captured by the second image capture device, and if the processor determines that the face is present in the image captured by the second image capture device, the timer tracks the time period or the number of iterations; wherein the processor triggers the alarm when the time period or the number of iterations is greater than a predetermined threshold; and wherein the timer resets the time period or the number of iterations resets to a predetermined value upon receiving a command from the processor indicating that movement of a person supported by a person support apparatus has exceeded the predetermined threshold, as determined by the processor upon processing the communication from at least one of the image capture devices.
