Method for determining the position of a coordinate system of an object in a 3D space

The method involves using at least two electronic cameras calibrated to a common global coordinate system. The cameras are treated as pinhole camera models for setting the coordinate system. The positions and orientations of their light input openings are measured with separate measurement systems, the cameras acquire object images that are evaluated to find object characteristics and the positions of the object and characteristics are derived. The method involves using at least two electronic cameras (c) and digital image processing. The cameras are calibrated to a common global coordinate system (1) and the workpiece (d) is then introduced between them. The cameras are treated as pinhole camera models for setting the coordinate system. The positions and orientations of their light input openings are measured with separate measurement systems, the cameras acquire images of the object that are evaluated to find object characteristics (e) and the positions of the object and of the characteristics are derived.
