Method, system and computer program for obtaining the transformation of an image

摘要

Disclosed is a method for obtaining a transformation of an image such that when said transformation is arranged on a surface that forms a horizontal plane and is seen by an observer from at least one appropriate viewing point a virtual representation of the image appears to be located in a perpendicular position in relation to the surface onto which it is arranged. The method comprises: - capturing the ratio of height to width of the image to be transformed; - capturing the width the transformation of the image should have; - capturing the height the virtual representation of the image should have; - establishing coordinate axes at the point on the surface onto which the viewing point is orthogonally projected, with the coordinate axes on the same horizontal plane corresponding to the surface on which the transformation of the image is arranged. The method also includes obtaining a first transformation angle of the image from at least two of the following parameters: - the distance between the point of the surface onto which the viewing point is projected and the position of the upper end of the transformation of the image furthest from the viewing point; - the projection on a first axis of the coordinate axes of the distance corresponding to the coordinate of the upper end of the transformation of the image furthest from the viewing point; and - the projection of a second axis of the coordinate axes of the distance corresponding to the coordinate of the upper end of the transformation of the image furthest from the viewing point. The method also includes obtaining the lateral transformation length of the image from the first transformation angle of the image and width that the transformation of the image should have and obtaining the transformation length of the image from the captured proportion of the image and the captured height of the virtual representation of the image. The method further includes obtaining a second transformation angle of the image from at least two of the following parameters: - the distance between the point on the surface onto which the viewing point is projected and the lower end of the transformation of the image in relation to said viewing point; - the projection in the first axis of the coordinate axes of the distance corresponding to the coordinate of the lower end of the transformation of the image closest to the viewing point; and - the projection in the second axis of the coordinate axes of the distance corresponding to the coordinate of the lower end of the transformation of the image closest to the projection of the viewing point. Advertising media generated by this method and computer programs for performing the method are also disclosed.
