Classification: CPC G  H  A | IPC A  G  H

Claim 0:
1. A contactless patient monitoring system, comprising:
a housing;
a thermal imager coupled to the housing, wherein the thermal imager is sensitive to a longwave infrared spectrum and configured to capture thermal image data of a target area within a first field of view;
a monochromatic imager operably coupled to the thermal imager and the housing, wherein the monochromatic imager is configured to operate within a near infrared light bandwidth and to capture grayscale image data of the target area within a second field of view;
an emitter operably coupled to the housing, wherein the emitter is configured to emit light within the near infrared light bandwidth proximate to the housing; and
a controller communicatively coupled to the thermal imager, the monochromatic imager, and the emitter, wherein the controller is configured to:
determine a facial region of a person in the thermal image data;
determine a region of interest in the grayscale image data that coincides with the facial region in the thermal image data;
calculate a pixel value within the region of interest;
adjust at least one of the emitter and the monochromatic imager when the pixel value is outside a predetermined pixel value range; and
determine vital signs information from each of the thermal image data and the grayscale image data.
