Abstract (en)
[origin: WO2009049750A2] The invention relates to a method for calibrating an assembly consisting of at least one omnidirectional camera (2) that is located on a vehicle (1) and an optical display unit. In said method: an image that is displayed by the display unit reproduces the perspective of an imaginary virtual camera above the object (1); an image from the virtual camera is projected into an object co-ordinate system and the resultant co-ordinates (Xw, Xw.Y) are projected into the omnidirectional camera; during the projection of the image of the virtual camera into the object co-ordinate system, pixels (xp) of the image of the virtual camera within an imaginary circle or ellipse (1) around the object are projected onto an imaginary plane, whilst pixels (xp) of the image outside the circle or ellipse are transformed by the virtual camera into the object co-ordinate system in such a way that they are projected onto an imaginary surface that rises from the edge of the circle or ellipse.
