Background
Driver monitoring systems and occupant monitoring systems are currently widely implemented in vehicles, both for safety purposes and for the purpose of improving comfort. For example, these systems can detect when the driver is drowsy, or automatically adjust the seat position and the mirror position based on the size of the driver. The information captured by these systems may also be transmitted to a heating and air conditioning system that can automatically adjust its air distribution based on the number of occupants in the vehicle and their location within the vehicle.
For these systems to function, they require images representative of the front and rear seats of the vehicle. At the same time, however, european regulations 125 define road safety regulations that prohibit the installation of cameras below or at the level of the driver's line of sightbase:Sub>A-base:Sub>A so as not to obstruct the driver's view. The line of sight is shown in figure 1.
It is also known, for example from patent CN 205468799, to arrange a camera in the side of the housing of the interior rear view mirror. However, this type of rear view mirror cannot be used in a driver or occupant monitoring system, since the rear view mirror housing is mounted to be movable relative to the support to allow the rear view mirror to be adjusted to the height and position of the driver. Considering such mobility in image processing software requires complicated image processing, and therefore requires a large memory and high computing power. Therefore, the camera of the driver or passenger monitoring system cannot be mounted in the rearview mirror housing.
