A method for determining a location relationship between a camera and a headlight of a vehicle includes positioning the vehicle at a distance in front of a surface exhibiting a calibration pattern, ascertaining the distance between the calibration pattern and the vehicle, projecting a pattern onto the surface using a headlight of the vehicle, and detecting characteristic features in the projected pattern. The method further includes performing the previous steps for at least one additional distance between the vehicle and the surface. In addition, the method includes interpolating positions of detected characteristic features that correspond in each case to one another at the different distances using a linear function, determining an intersection of the ascertained linear functions, and determining the location relationship between the camera and the headlight of the vehicle on the basis of the position of the intersection of the ascertained linear functions relative to the camera.

A method for checking the plausibility of detected features of a light distribution of a headlamp of a motor vehicle includes irradiating, by the headlamp, a scene in surroundings of the motor vehicle; capturing, by a camera of the motor vehicle, the irradiated scene in an image; dynamically seeking and identifying at least one initial optical feature in the image, adaptively producing and analyzing local surroundings of the at least one initial optical feature; dynamically extracting at least one further optical feature from the local surroundings; and carrying out, using a learned algorithm and on the basis of the at least one initial optical feature and the at least one further optical feature, an adaptive check as to whether the at least one initial optical feature and the at least one further optical feature are plausibly arranged in the local surroundings.
