1. A method for the computer-aided optical testing of a rope, such method implemented using at least one computer processor coupled to at least one computer storage device, the method comprising: storing in the at least one storage device an image data set for at least one portion of the rope; storing in the at least one storage device target values of a pictorial longitudinal extension of a representation of wires of the rope relative to a pictorial longitudinal extension of the rope in the image data set, wherein the target values electronically represent the rope as defect-free; determining the pictorial longitudinal extension of the wires in the image data set, wherein the determining comprises adapting an estimated longitudinal extension to the image data set; determining at least one quality value using a quality norm as a function of the determined pictorial longitudinal extension of the wires and the target values of the pictorial longitudinal extension of the wires, including comparing a wire angle of the rope with a wire angle of the rope in the image data set, wherein the wire angle is an angle that is enclosed between the longitudinal direction of the rope and the longitudinal direction of the wires; discriminating pictorial positions within the image data set of the rope, including determining if at least one quality value exceeds or falls below a predetermined, assigned quality threshold value; and providing the discriminated pictorial positions.
