Abstract
A patient monitoring system includes a first imager configured to capture first image data of a target area within a first field of view. A second imager is configured to capture second image data of the target area within a second field of view. An emitter is configured to emit light within a predetermined wavelength range. A controller is configured to determine a facial region of a person in the first image data, determine a region of interest in the second image data that coincides with the facial region in the first image data, calculate a pixel value within the region of interest, adjust at least one of the emitter and the second imager is the pixel value is outside a predetermined pixel value range, and determine vital signs information from at least one of the first image data and the second image data.
