Abstract

A data model which is designed for being superposed with an image of a real object in an optical object tracking process is determined by the following steps: providing a three-dimensional CAD model (10) for representing the real object, and thereafter there are different synthetic two-dimensional views (31 to 34) of said CAD model (10) generated. Each generated view (31 to 34) is subjected to edge extraction for determining at least one extracted edge (38, 39) in the respective view, with the edges (38, 39) extracted from said respective views (31 to 34) being transformed to a three-dimensional contour model (85, 91) corresponding to said data model to be determined. Permits rapid and efficient generation of a contour model as a data model intended for being superposed with an image of a real object.
