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.

Claim (Index 16):
A method for operating a projection device for displaying discretely stored image information with the aid of at least two controllable and regulatable light sources, which each transmit a beam component of a scanning beam, and using components for focusing, aligning and moving the beam components, so that the corresponding pixels overlap as much as possible on a projection surface and may be moved in a predefined trajectory over the projection surface, the method comprising:\n a. assigning each pixel generated by a light source an x- and a y-projector coordinate in accordance with its position on the trajectory, simultaneously generated pixels of different light sources being assigned the same x- and y-projector coordinates; b. converting each of the x and y projector coordinates to corresponding image coordinates of the image information with the aid of an x-dewarping function and y-dewarping function, respectively, the dewarping functions being determined in advance for a reference beam in a calibration method, and the image coordinates acting as a reference pixel position for all of the light sources; c. determining an offset of the position of the pixels generated by the individual light sources with respect to corresponding reference pixel positions with the aid of an x- or y-offset function, which is determined in advance for each light source in a calibration method; and d. adding the offset determined for individual light sources is added to the image coordinates of the reference pixel position, to determine the image coordinates of the pixels of each one of the individual light sources.
