A method of controlling a HUD system (6) of a road vehicle (1), the method including the steps of : generating a first electronic image displaying information; projecting an electronic image onto a windscreen (3) of the road vehicle (1) by means of a projector (8); memorizing an optical distortion map of the optical system defined by the projector (8) and the windscreen (3) ; supplying the first electronic image to a processing unit (12) ; generating, by means of the processing unit (12) , a second electronic image by applying the optical distortion map to the first electronic image, so that the second electronic image is equally but oppositely distorted with respect to the optical system defined by the projector (8) and the windscreen (3) ; and supplying the second electronic image to the projector (8) to project the second electronic image onto the windscreen (3). |
