A method of aligning a laser scanner whose alignment can at least be changed about a pitch axis and a roll axis by means of an adjustment apparatus, in which: - a reference object (14, 14') is arranged within a scanning zone of the laser scanner, with the reference object (14, 14') having a plurality of strip-like markings (16A - 16C, 18) which are detectable by the laser scanner and which run transversely to a reference line such that the markings (16A - 16C, 18) run perpendicular to the reference line or a deviation from the perpendicular amounts to no more than 20° and are spaced apart from one another in the direction of the reference line; - the reference object (14, 14') is scanned by means of the laser scanner to generate a scanning pattern of the reference object (14, 14'), with the shape and/or the arrangement of the markings (16A - 16C, 18) being selected such that it is recognized based on the design of the generated scanning pattern whether the alignment of the laser scanner corresponds to a desired alignment or whether the alignment of the laser scanner deviates from the desired alignment; and - the alignment of the laser scanner is changed on the basis of a recognized deviation of the alignment, characterized in that some of the markings (16A - 16C, 18) are associated with a first group and other ones of the markings (16A - 16C, 18) are associated with a second group; in that the markings (16A - 16C, 18) associated with the first group are arranged at the respective one side with respect to the reference line and with respect to a line of symmetry running perpendicular to the reference line and the markings (16A - 16C, 18) associated with the second group are arranged at the respective other side with respect to the reference line and with respect to the line of symmetry; and in that the shape and/or the arrangement of the markings (16A - 16C, 18) is/are selected such that it is recognized based on the design of the scanning pattern whether the alignment of the laser scanner deviates from the desired alignment with respect to the pitch axis and/or with respect to the roll axis, with the alignment of the laser scanner being changed about that axis (X, Y) for which a deviation was recognized so that this deviation is reduced or eliminated. - a reference object (14, 14') is arranged within a scanning zone of the laser scanner, with the reference object (14, 14') having a plurality of strip-like markings (16A - 16C, 18) which are detectable by the laser scanner and which run transversely to a reference line such that the markings (16A - 16C, 18) run perpendicular to the reference line or a deviation from the perpendicular amounts to no more than 20° and are spaced apart from one another in the direction of the reference line; - the reference object (14, 14') is scanned by means of the laser scanner to generate a scanning pattern of the reference object (14, 14'), with the shape and/or the arrangement of the markings (16A - 16C, 18) being selected such that it is recognized based on the design of the generated scanning pattern whether the alignment of the laser scanner corresponds to a desired alignment or whether the alignment of the laser scanner deviates from the desired alignment; and - the alignment of the laser scanner is changed on the basis of a recognized deviation of the alignment,
