1. A method for the automatic configuration of a 3D sensor for safe object tracking, comprising:
recording at least one 3D image with the 3D sensor; and
fixing a detection region in which safety related objects can move using the at least one 3D image, the detection region being within a detection zone of the 3D sensor, and wherein the safe object tracking is restricted to the detection region;
wherein picture elements corresponding to a reference area are identified in the at least one 3D image and the detection region is fixed with respect to the picture elements corresponding to the reference area,
wherein the at least one 3D image comprises an image sequence having a plurality of 3D images which are recorded while the safety related objects move through the detection zone, and
wherein the picture elements corresponding to the reference area are repeatedly identified using the 3D images from the image sequence to also detect temporarily covered parts of the reference area.
