Title: METHOD FOR TRANSFORMING A DRAWING BETWEEN TWO DRAWING SURFACES
Abstract:
A method for transforming a drawing between two drawing surfaces (100, 105). Firstly, at least one first marker signal is read in, which represents at least three first marker positions of first markers (125) on a first drawing surface (100) imaged on a first camera image. A first transformation specification (135) for transforming the first drawing surface (100) into a reference coordinate system (140) using the first marker positions is then determined. At least one first drawing signal is received, which represents first drawing positions of first drawing points (130) on the first drawing surface (100) imaged on the first or a further first camera image. The first drawing positions are transformed into the reference coordinate system (140) using the first transformation specification (135) in order to provide first reference drawing positions (145). At least one second marker signal is read in, which represents at least three second marker positions of second markers (170) on a second drawing surface (105) imaged on a second camera image. A second transformation specification (180) for transforming the second drawing surface (105) into the reference coordinate system (140) using the second marker positions is determined. The first reference drawing positions (145) are transformed into the second drawing surface (105) using the second transformation specification (180) in order to provide transformed first drawing positions (190).
