In a method for calibrating a laser scanner of a vehicle by at least one reflection unit for reflecting a laser beam of the laser scanner, the at least one reflection unit including a first plate, a second plate, and a screen, the first plate being arranged between the second plate and the screen in a beam direction, the first plate having a first reflection surface, the second plate having a second reflection surface, the screen having a third reflection surface, a gap that extends in the vertical direction and in a transverse direction being formed between the first plate and the second plate, and a projection of the gap in the beam direction being incident on the third reflection surface, an alignment of the laser scanner being checked by a laser beam of the laser scanner being directed at the at least one reflection unit and the laser beam being moved in the transverse direction along the at least one reflection unit, and, for a plurality of positions of the laser beam in the transverse direction, a respective distance of the laser scanner from that reflection surface from which the laser beam is reflected being measured, and an alignment of the laser scanner being determined from the measured distances, and the alignment of the laser scanner being corrected in the case of an incorrect alignment of the laser scanner. An apparatus, configured to perform the method, includes at least one vehicle having a laser scanner, and at least one reflection unit for reflecting a laser beam of the laser scanner.
