Method and system for determining a data model for the superimposition with a real object in a method for object tracking

摘要

A method for determining a data model of a virtual information, which is determined, in a method for the virtual object tracking with an image of a real object to be superimposed, with the following steps:– Providing a three-dimensional cad - model (10) for the simulation of the real object,– Generation of different synthetic two-dimensional views (31, 34) of the cad - model (10),– each generated view (31, 34) is an edge extraction for the determination of at least one extracted edge (38, 39) is subjected to in the respective view, whereby, in accordance with the edge extraction respective two-dimensional edge points (37) of an extracted edge (38, 39) are determined,– Conversion of the from the respective views (31, 34) extracted edges (38, 39) to form a three-dimensional contour model (85, 91), which corresponds to the data model, in which a corresponding three-dimensional position of the respective edge points (37) is determined, wherein an amount of three-dimensional points (70) is obtained, from which the three-dimensional contour model (85, 91) is determined.
