Abstract
A method for calibrating a projection device, the projection device being equipped with at least two controllable and regulatable light sources, which each transmit a beam component of a scanning beam. The calibration method includes defining a reference beam for the scanning beam; determining, in each instance, a dewarping function for the x-projector coordinate and for the y-projector coordinate of the reference beam, each dewarping function converting the specific projector coordinate to corresponding image coordinates, which are assigned to the image information; determining, in each instance, an offset function for the x-projector coordinate and the y-projector coordinate for all beam components, each offset function approximating the offset between the specific x- or y-image coordinate of the reference beam and the x- or y-image coordinate of the respective beam component.
