Infant monitoring systems and methods using thermal imaging
First Claim
1. A monitoring system comprising:
- an infrared imaging module comprising a focal plane array (FPA) configured to capture thermal images of a scene within a field of view (FOV) of the infrared imaging module;
a housing at least partially enclosing the infrared imaging module and configured to be positioned to place at least a portion of an infant within the FOV; and
a processor in communication with the infrared imaging module and the visible light camera, the processor configured to;
track an oronasal region of the infant in the thermal images;
analyze thermal data in pixels of the thermal images corresponding to the tracked oronasal region to detect a periodic presence of CO2 gas imaged in the tracked oronasal region represented by a periodic variation in the thermal data;
determine whether the infant is breathing normally based on the analysis of the thermal data in the pixels corresponding to the tracked oronasal region to detect the periodic presence of the imaged CO2 gas; and
generate monitoring information relating to the infant, the monitoring information comprising an alarm generated in response to determining that the infant is not breathing normally.

Abstract
Various techniques are disclosed for systems and methods using thermal imaging to monitor an infant or other persons that may need observation. For example, an infant monitoring system may include an infrared imaging module, a visible light camera, a processor, a display, a communication module, and a memory. The monitoring system may capture thermal images of a scene including at least a partial view of an infant, using the infrared imaging module enclosed in a portable or mountable housing configured to be positioned for remote monitoring of the infant. Various thermal image processing and analysis operations may be performed on the thermal images to generate monitoring information relating to the infant. The monitoring information may include various alarms that actively provide warnings to caregivers, and user-viewable images of the scene. The monitoring information may be presented at external devices or the display located remotely for convenient viewing by caregivers.

9. A method comprising:
-
capturing, at a focal plane array (FPA) of an infrared imaging module, thermal images of a scene within a field of view (FOV) of the infrared imaging module, wherein the infrared imaging module is positioned so that at least a portion of an infant is placed within the FOV of the infrared imaging module; tracking an oronasal region of the infant in the thermal images; analyzing thermal data in pixels of the thermal images corresponding to the tracked oronasal region to detect a periodic presence of CO2 as imaged in the tracked oronasal region represented by a periodic variation in the thermal data; determining whether the infant is breathing normally based on the analysis of the thermal data in the pixels corresponding to the tracked oronasal region to detect the periodic presence of the imaged;
CO2 gas; andgenerating monitoring information relating to the infant, the monitoring information comprising an alarm generated in response to determining that the infant is not breathing normally. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 18)
