POSITION DETERMINATION FOR AN OBJECT BY MEANS OF THE SENSING OF A POSITION PATTERN BY AN OPTICAL SENSOR

摘要

An apparatus (10) for determining a position for an object (5) in relation to a presentation of an image (3) that is to be presented comprises a position pattern generator (12) for generating a position pattern (13) which is divided into a multiplicity of pattern sections wherein each of the pattern sections has a unique bit pattern comprising a multiplicity of bit patterns and wherein the bit patterns are Gray coded in a generalized manner. The apparatus (10) also comprises a combination unit (14) for combining the position pattern (13) with the at least one image (3) that is to be presented and for providing a corresponding combined image and an optical sensor (15) for optically sensing an image detail from the combined image wherein the image detail correlates to the position of the object (5). In addition the apparatus (10) comprises a filter (16) for extracting at least one bit pattern which corresponds to a pattern section from the position pattern (13) from the image detail and for providing at least one corresponding extracted pattern section and also a determination device for determining the position of the object (5) on the basis of the at least one extracted bit pattern. A method for determining the position of an object (5) is likewise disclosed.
