1. A method to control a drive mechanism of an automated machine for approaching a point of interest on an object, the object having a surface on which reference information of the object is provided as a one- or two-dimensional pattern, the method comprising:

  • capturing at least one image of the object using at least one camera of the automated machine, wherein each of the at least one cameras is arranged at a predetermined known position with the automated machine;

    identifying the pattern in the at least one image;

    determining before starting the measurement a position and orientation of the pattern relative to the at least one camera by image recognition, wherein identifying the pattern comprises reading position information related to a position and orientation of the pattern on the object, the position information being content of the reference information encoded in the pattern or is extracted from a data base of a data base storage device as part of an object data set comprising reference information of the object and being assignable to the object by the reference information encoded in the pattern;

    determining a position and orientation of the object based on the position information related to the position and orientation of the pattern on the object and the determined position and orientation of the pattern relative to the at least one camera; and

    controlling the drive mechanism based on the determined position and orientation of the object.
