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: providing an image data set for at least one portion of the rope; providing 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; 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; 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.
