Abstract: A method for generating a representation of an elevator rope includes determining a first edge and a second edge of the elevator rope from measurement data obtained from consecutive measurement instances; and generating a representation of the elevator rope by combining the measurement data of the consecutive measurement instances in accordance with the determined first edge of the elevator rope and the determined second edge of the elevator rope. Some aspects relate to a control unit and a computer program product.
