Abstract
System and methods for non-contact video-based patient monitoring are described. The systems and methods may include locating one or more condensation removal elements on a transparent enclosure for removal of condensation that may be obstructing the view between a video camera used to monitor a patient and the patient. The systems and methods may further include steps for monitoring the quality of the video stream and automatically initiating the condensation removal elements when a deterioration in the quality of the video stream is detected.
Claims (29)
1 . A video-based patient monitoring method, comprising:
obtaining a video stream of a patient located within a transparent enclosure, the video stream obtained from a non-contact detector positioned outside the transparent enclosure;
periodically or continuously monitoring the quality of the video stream to detect a deterioration in the quality of the video stream;
when a deterioration in the quality of the video stream is detected, automatically initiating one or more condensation removal elements located on the transparent enclosure;
after automatically initiating the one or more condensation removal elements located on the transparent enclosure, periodically or continuously monitoring the quality of the video stream to detect a restoration in the quality of the video stream; and
when a restoration in the quality of the video stream is detected, automatically terminating the one or more condensation removal elements located on the transparent enclosure.
2 . The video-based patient monitoring method of claim 1 , wherein the non- contact detector is a depth sensing camera.
3 . The video-based patient monitoring method of claim 1 , wherein monitoring the quality of the video stream to detect a deterioration in the quality of the video stream comprises at least one of monitoring whether a video analysis of the video stream can be successfully completed or monitoring whether a physiological parameter of the patient can be successfully calculated from the data within the video stream.
4 . The video-based patient monitoring method of claim 3 , wherein detection of a deterioration in the quality of the video stream occurs when at least one of a video analysis of the video stream cannot be successfully completed or a physiological parameter of the patient cannot be successfully calculated from the data within the video stream, or both.
5 . The video-based patient monitoring method of claim 4 , wherein video analysis of the video stream comprises detecting a patient's face using a facial recognition algorithm.
6 . The video-based patient monitoring method of claim 1 , wherein the one or more condensation removal elements are located on the transparent enclosure such that the condensation removal elements are within a field of view of the non-contact detector.
7 . The video-based patient monitoring method of claim 1 , wherein the one or more condensation removal elements are located on the transparent enclosure such that the condensation removal elements are located on or proximate a straight-line path extending from the non-contact detector and the patient.
8 . The video-based patient monitoring method of claim 1 , wherein monitoring the quality of the video stream to detect a restoration in the quality of the video stream comprises at least one of monitoring whether a video analysis of the video stream can be successfully completed or monitoring whether a physiological parameter of the patient can be successfully calculated from the data within the video stream.
9 . The video-based patient monitoring method of claim 8 , wherein detection of a restoration in the quality of the video stream occurs when at least one of a video analysis of the video stream can be successfully completed or a physiological parameter of the patient can be successfully calculated from the data within the video stream.
10 . The video-based patient monitoring method of claim 9 , wherein video analysis of the video stream comprises detecting a patient's face using a facial recognition algorithm.
11 . The video-based patient monitoring method of claim 1 , wherein the one or more condensation removal elements are heating elements.
12 . The video-based patient monitoring method of claim 11 , wherein the heating elements are embedded within the transparent enclosure.
13 . The video-based patient monitoring method of claim 1 , wherein the one or more condensation removal elements are wiper blades, optionally having a hydrophobic coating applied thereon.
14 . The video-based patient monitoring method of claim 1 , further comprising transmitting a message regarding the deterioration in the quality of the video stream.
15 . The video-based patient monitoring method of claim 14 , further comprising displaying the message on a handheld device.
16 . The video-based patient monitoring method of claim 14 , further comprising presenting the message on a local display.
17 . The video-based patient monitoring method of claim 16 , wherein the message comprises an alarm or flashing light proximate the transparent enclosure.
18 . A video-based patient monitoring method, comprising:
obtaining a video stream of a patient located within a transparent enclosure, the video stream obtained from a non-contact detector positioned outside the transparent enclosure;
periodically or continuously monitoring the quality of the video stream to detect a deterioration or a restoration in the quality of the video stream;
when a deterioration in the quality of the video stream is detected, automatically initiating one or more condensation removal elements located on the transparent enclosure; and
when a restoration in the quality of the video stream is detected, automatically terminating the one or more condensation removal elements located on the transparent enclosure.
19 . The video-based patient monitoring method of claim 18 , wherein the non-contact detector is a depth sensing camera.
20 . The video-based patient monitoring method of claim 18 , further comprising transmitting a message regarding the deterioration in the quality of the video stream.
