MONITORING OF THE QUALITY OF THE SLEEP OF A BABY BY COMBINATION OF MULTIMODAL DATA INCLUDING PHOTOPLETHYSMOGRAPHY

摘要

The invention relates to a device (D) for automatically determining information (IQ) representative of the quality of the sleep of a living being, without contact with said living being, on the basis of a stream of data (F1, F2, F3... FN) relating to said living being and issued from at least two sensors (C1, C2, C3... CM), at least one of said sensors being a video camera filming said living being and delivering a stream corresponding to a physiological datum of said living being, this device including means for: establishing streams of measurements from said streams of data; decomposing the stream established by photoplethysmography into regions of interest, and establishing a sum, weighted by a pulsality measured for each region, of the photoplethysmography signals established for each region; and combining said streams of measurements in order to deliver said information, while taking into account an estimation of the quality of said streams of data.
