Abstract: A computer-aided method, system and computer program product are provided for optical testing of a rope. Such method includes: providing an image data set for at least one portion of the rope; providing target values of a pictorial longitudinal extension of the representation of wires relative to a pictorial longitudinal extension of the rope in the image data set; determining a pictorial longitudinal extension of the wires in the image data set, including 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, where at least one quality value exceeds or falls below a predetermined, assigned quality threshold value; and providing the discriminated pictorial positions.

Abstract: A method and a configuration for automatically or visually detecting material defects, in particular cracks, in a workpiece, includes applying a test agent to the workpiece. The test agent contains color pigments which can be excited by using shortwave light. The workpiece is then irradiated with shortwave light from a light source, light emitted by the workpiece is detected by an observer's eye or by a detector, and the signals from the detector are evaluated by an electronic evaluation device in order to determine the material defects. The light source is associated with a first optical interference filter which selects the light emitted by the light source, as a bandpass filter, before the light impinges on the workpiece.
