1. A method of operating a system for unobtrusively measuring a person'"'"'s respiration, the method comprising acts of:
- capturing images of a person lying down or lying in bed, by at least one video camera,analyzing the images, to determine the rotation of the head of the person about the longitudinal axis of a body of the person,determining by the video processor, from the images and rotation of the head which of at least two microphones is a microphone in a line-of-sight of the person'"'"'s breathing and which of the at least two microphones is a microphone not in the line-of-sight of the person'"'"'s breathing,computing from the images by the video processor, a distance from the person'"'"'s head to each of the at least two microphones positioned on opposite sides of the person'"'"'s head, andmeasuring by an audio analyzer, the person'"'"'s respiration depending on the distances from the head to each microphone computed by the video processor and on the determination by the video processor of which of the at least two microphones is the microphone in the line-of-sight and which of the at least two microphones is the microphone not in the line-of-sight, as parameters.

Abstract
A method and a system for unobtrusively measuring a person'"'"'s respiration, wherein at least two microphones positioned at either side of a person'"'"'s head are utilized based on a distance of the persons head to the microphones and an identification of which microphone is in a line of sight and which is out of the line of site of the person'"'"'s breathing as computed on the basis of images captured by a video camera.

11. A system for unobtrusively measuring a person'"'"'s respiration, the system comprising:
-
at least one video camera configured to capture images of a person lying down or lying in bed, at least two microphones positioned on opposite sides of the person'"'"'s head, a video processor configured to analyze the images, to determine the rotation of a head of the person about the longitudinal axis of a body of the person, the video processor configured to determine from the rotation of the head and the images, which of the at least two microphones is a microphone in a line-of-sight of the person'"'"'s breathing and which of the at least two microphones is a microphone not in the line-of-sight of the person'"'"'s breathing, the video processor configure to compute a distance from the person'"'"'s head to each of the at least two microphones positioned on opposite sides of the person'"'"'s head, and an audio analyzer configured to measure the person'"'"'s respiration depending on the distances from the head to each microphone computed by the video processor, and depending on the determination of which of the at least two microphones is the microphone in the line-of-sight and which of the at least two microphones is the microphone not in the line-of-sight, as parameters. - View Dependent Claims (12)
