摘要： The invention relates to a method for checking the adjustment of a headlamp (2, 3) in a motor vehicle (1). In the method, in a step a), in a predetermined basic position of the headlamp (2, 3) a projection surface (PF) facing the headlamp (2, 3) is detected by means of an image recording device (SK) of the motor vehicle (1) at one or more recording times comprising a recording time with activated headlamp (2, 3), such that image data (PF) are obtained with spatial position information, wherein the image data include the projection surface (PF). In a step b) a 3D model of the projection surface (PF), which describes the projection surface (PF) in a reference system of the motor vehicle (1) on the basis of a plurality of positions on the surface of the projection surface (PF), is determined from the image data. In a step c), from the image data an actual position (P
Li , P
Ri ) of an area of light within the light distribution of the headlamp (2, 3) on the projection surface (PF) is identified in the reference system of the motor vehicle (1), wherein the area of light is characterised by a beam path (
SR
L
, SR
R )) predetermined for the basic position in the light of the headlamp (2, 3) in the reference system of the motor vehicle (1). On the basis of the predetermined beam path (
SR
L
, SR
R ) and the 3D model of the projection surface (PF), in a step d) a desired position (P
Ls , P
Rs ) of the area of light within the light distribution of the headlamp (2, 3) on the projection surface (PF) is determined in the reference system of the motor vehicle (1). Finally, in a step e) an adjustment of the headlamp (1, 2) is detected if the deviation between the actual position (P
Li , P
Ri ,) and the desired position (P
Ls , P
Rs ) of the area of light exceeds a predetermined threshold value.
