Abstract: A method is described for the identification and localization of objects, where at least one transponder provided on the respective object is excited to emit transponder data stored in the transponder which characterize the respective object and where the transponder data emitted are detected. The object is additionally scanned by at least one optical sensor. Furthermore, the object is identified and its location determined from a combination of optical data detected by the optical sensor and the transponder data identified. Furthermore, a corresponding apparatus for the performance of the method is described.

Abstract: An apparatus and method for the recognition of codes has a light transmitter for the transmission of light signals in the direction of a scanning region, a light receiver for the reception of a light signal remitted from the scanning region, and a control and evaluation unit for the control of the light transmitter and the light receiver and for the determination of a code from the light signal received. The control and evaluation unit includes a trigger circuit triggering the determination of a code and a distance determination unit or image detection unit (which acts on the trigger circuit) for the detection of an object present in the scanning region which is integrated into the apparatus.
