A method for projecting an image onto a projection surface by means of at least a first and a second beam, - wherein a target impression of the image is intended to be produced by superposing the projection of the first and the second beam (110; 210) on the projection surface, - wherein the at least first and second beam are steered by means of a first mirror on to the projection surface for the purposes of projecting the pixels, - wherein an actual impression of the image that deviates from the intended impression is produced by an actual deviation (d) of the projection of the first and of the second beam (110; 210) on the projection surface including the method steps of: A) determining the actual deviation of the projection of the first from the second beam (110; 210) on the projection surface, B) varying the intensity of the first beam and/or the second beam in time according to the deviations determined in method step A) for the purposes of producing the target impression, wherein a second mirror is oriented between the first mirror and the projection surface and only a single beam (110, 210) is operational in each case for the purposes of carrying out method step A) and wherein - the second mirror is oriented in such a way that it steers at least a portion of the respective operational beam (110, 210) on a first detector with a fixed position, characterized in that - the first mirror is brought into a first orientation for the first beam, in which first orientation a maximum intensity of the first beam is measured at the first detector, and wherein the first mirror is brought into a second orientation for the second beam, in which second orientation a maximum intensity of the second beam is measured at the first detector, and the first and second orientation of the first mirror are each determined by virtue of the first mirror being irradiated by an additional beam and the deflection thereof being determined by means of a second detector, wherein the orientation of the first mirror is ascertained by the deflection of the additional beam, and moreover - the additional beam is disposed at an inclined angle with respect to the at least first and second beam (110, 210), wherein an angle deviation between the first and second beam is ascertained from the first and second orientation of the first mirror, said angle deviation being used to determine the actual deviation (d) of the first and second beam (110, 210) on the projection surface. - wherein a target impression of the image is intended to be produced by superposing the projection of the first and the second beam (110; 210) on the projection surface, - wherein the at least first and second beam are steered by means of a first mirror on to the projection surface for the purposes of projecting the pixels, - wherein an actual impression of the image that deviates from the intended impression is produced by an actual deviation (d) of the projection of the first and of the second beam (110; 210) on the projection surface A) determining the actual deviation of the projection of the first from the second beam (110; 210) on the projection surface, B) varying the intensity of the first beam and/or the second beam in time according to the deviations determined in method step A) for the purposes of producing the target impression, - the second mirror is oriented in such a way that it steers at least a portion of the respective operational beam (110, 210) on a first detector with a fixed position, - the first mirror is brought into a first orientation for the first beam, in which first orientation a maximum intensity of the first beam is measured at the first detector, and wherein the first mirror is brought into a second orientation for the second beam, in which second orientation a maximum intensity of the second beam is measured at the first detector, and the first and second orientation of the first mirror are each determined by virtue of the first mirror being irradiated by an additional beam and the deflection thereof being determined by means of a second detector, wherein the orientation of the first mirror is ascertained by the deflection of the additional beam, - the additional beam is disposed at an inclined angle with respect to the at least first and second beam (110, 210), wherein an angle deviation between the first and second beam is ascertained from the first and second orientation of the first mirror, said angle deviation being used to determine the actual deviation (d) of the first and second beam (110, 210) on the projection surface.
