<p>The invention relates to a system for obtaining the transformation (30) of an image, said system comprising means for capturing image proportions; means for capturing the width of the transformation; means for capturing the height of the virtual representation of the image; means for establishing coordinate axes at the point on the surface, onto which the viewing point is orthogonally projected; means for obtaining a first transformation angle (±) from two parameters: the distance between the point on the surface onto which the viewing point is projected and the upper end furthest from the transformation; and the distance corresponding to the coordinate of the upper end furthest from the transformation in relation to said viewing point, and the distance corresponding to the coordinate of the upper end furthest from the transformation in relation to the viewing point; means for obtaining the lateral transformation longitude (L3) from the first transformation angle and the transformation width; means for obtaining the longitude (L4) of the transformation (30) from the captured proportions and height of the virtual representation; means for obtaining a second transformation angle (») from two parameters: the distance between the point on the surface onto which the viewing point is projected and the lower end closest to the transformation; and the distance corresponding to the coordinate of the lower end closest to the transformation.</p> |
