Abstract:
In a method for suppression of reflections in at least one camera image of a camera of a motor vehicle, the camera generates the at least one camera image and thereby a polarization filter device dampens light incident from a surrounding field in regard to a predetermined polarization direction. An estimator device estimates a respective orientation of a respective surface normal of at least one surface on at least one environment object and an adjusting device determines a respective target polarization direction for the polarization filter device in dependence on the respective estimated orientation of the at least one surface normal, by which a respective representation of reflections at the respective surface is reduced in the at least one camera image, and generates a control signal according to the respectively determined target polarization direction, and the polarization filter device adjusts its polarization direction in dependence on the control signal.
