Abstract
A method for determining a distance Dsensor between an image sensor and a target area of a driver of a vehicle, comprising arranging a light source at a known geometric relationship with respect to the image sensor, such that a structure in the vehicle at least occasionally casts a shadow in the target area, determining a distance Dlight source between the light source and the target area based on an image acquired be the image sensor of the target area including the shadow and a geometric relationship (e.g. distance) between the light source and the structure, and determining the distance Dsensor based on the distance Dlight source and the geometric relationship between the light source and the image sensor. With this approach, a reliable determination of the distance to the target area may be provided using only one single image sensor.
