Abstract: The monitoring system (1) comprises:



a light source (3),
an image acquisition device (5) comprising a shutter (11) which allows light to pass during a period (P1) when the source is active and during a period (P2) when the source is inactive, the light received by a sensor (9) comprising a component (Ca) due to ambient illumination and a component (Ci) due to the light source;
a processing unit (7) configured for determining a physiological parameter of the occupant by photoplethysmography.




The shutter (11) allows light to pass during a third period (P3), said light comprising the component (Ca) due to ambient illumination and the processing unit (7) being configured for subtracting this component (Ca) from the light received (9) during the other two periods for the purpose of isolating the component (Ci) due to the source in acquired images.

Abstract: A method for defining the clothes type of an occupant of a vehicle is disclosed. The method includes acquiring a video stream of the cabin of the vehicle, performing skin segmentation from images of the video stream to classify each image pixels as skin pixels, non skin human pixels, and background pixels, and detecting key body points of each occupant of the vehicle from the images. The method also includes calculating the skin versus non skin percentage levels over the body parts of each occupant of the vehicle seen in the image and defining the clothes type of each occupant based on the calculated skin versus non skin percentage levels of each body part of each occupant.
