1. A method for recognizing deviations (D3) of a surface (1) of an object, said method comprising the steps of:

  • generating, via a computing unit, pre-specified machine-readable reference data (A1);

    computing, via the computing unit, an at least sectionally parametric machine-readable description of the surface (1) as a target surface model (D4), said at least sectionally parametric machine-readable description of the surface (1) being computed based at least in part upon the pre-specified machine-readable reference data (A1);

    capturing, via a sensing unit, measured data (D1) of the surface (1), said sensing unit being configured to capture data at least one tactilely, optically, or via sounds, the sounds comprising at least one of ultrasonic or a radar; and

    performing, via the computing unit, a comparison of the measured data (D1) of the surface (1) captured via the sensing unit with the pre-specified machine-readable reference data (A1), the comparison being carried out based upon said target surface model (D4),wherein the target surface model (D4) is computed, via the computing unit, from the pre-specified machine-readable reference data (A1) using statistical methods, with a plurality of different data sets of reference data (A1).
