Abstract
A system for determining the position of a movable object in space includes a marker which is to be applied to the object. The marker has a surface which is subdivided into a plurality of individual fields. The fields each have a statistical noise pattern. The system also includes an image capture unit which is remote from the object and is arranged to capture an image of the marker. The system further includes an image evaluation unit which stores a reference image of the noise patterns and is designed to locate at least one of the fields in the currently captured image of the marker by comparison with the reference image in order to determine a current position of the marker in space. There are corresponding methods for determining a position the object.
