Method for determining an axle geometry by recording and evaluating a topographical image of a face (6) of a wheel (1) fitted to an axle (2), and a sensor (10) for execution of the method. The method includes projecting light with a coding onto an area on the face (6) of the wheel (1) from a projecting direction; recording the light reflected from the area on the face (6) of the wheel (1) with an image converter (8), from a direction other than the light projecting direction; determining three-dimensional surface coordinates for the topographical image of the face (6) of the wheel (1) from the recorded light; and evaluating the topographical image in relation to a reference system.

摘要:
An inspection apparatus (10) applying two dimensional nondestructive examination images onto a three dimensional solid model of a component (12) to display a virtual component (73) that may be manipulated to perform a nondestructive inspection. The two dimensional nondestructive examination images may be acquired from a plurality of views of the component in order to provide full coverage of the surface to be inspected, with appropriate stitching of images in regions of overlap between adjacent views. The two dimensional images (62) may be color or black and white photographs or ultraviolet or infrared images, for example. Multiple types of nondestructive examination images, results of inspection data evaluations, and design, operational and/or maintenance information may be displayed separately or jointly on the three dimensional solid model. Surface features of interest that are mapped as defined areas (76) on the three dimensional solid model may be displayed simultaneously in different views on 2D and 3D images of the virtual component.
摘要:
An optical measuring device for a three-dimensional measuring of a hollow space formed within an object is provided. The optical measurement device has a light source, which is provided for emitting illumination light along an illumination beam path, and an optical deflection element, which spatially structures the radiated illumination light such that on an inside wall an illumination line forms, which extends along the longitudinal axis. The shape of the line is dependant on the size and shape of the hollow space. Further, the optical measuring device has a camera, which detects the illumination line via an imaging beam path at a triangulation angle. Through an appropriate evaluation of the image of the detected shape and size of the illumination line by the camera, the three-dimensional shape of the hollow space is determined.

摘要:
A method and device for performing the method of inspecting an object for the purpose of detecting defective surface regions of the object, comprising the steps of using a scanning device to survey a surface of the object to be inspected and generating two-dimensional image data and a measured surface profile in at least one cross-sectional plane through the object in each case; using a computer device to evaluate the two-dimensional image data in order to localize a potentially defective surface region; using the computer device to generate a calculated surface profile within the potentially defective surface region in the cross-sectional plane on the basis of the measured surface pro-file outside of the potentially defective surface region of the cross-sectional plane; using the computer device to compare the calculated and measured surface profiles within the potentially defective surface region, the localized surface region being assessed as actually defective if defined differentiating features are present.
摘要:
The invention relates to a method for treating plasma under continuous atmospheric pressure of, in particular, electrically insulating workpieces, in particular material plates or strips. According to said method, the workpiece which is to be machined, is arranged at a distance below at least one electrode which is made of two barrier electrodes, which are arranged in a successive manner in the direction of displacement with a gap, and which extends in a manner which is transversal to the direction of displacement at least over the width of the surface of the workpiece which is to be machined. The electrode and the workpiece are mutually offset in the direction of displacement. High voltage, which is in the form of an alternating voltage, is applied to the barrier electrodes, in order to provoke at least plasma discharge in the gap. The plasma discharge is driven by the gas flow from the gap in the direction of the surface of the workpiece which is to be machined. The invention is characterised in that the surfaces of the barrier electrodes which are oriented towards the surface of the workpiece which is to be machined are impinged upon with high pressure.

摘要:
The present invention provides a method with which a workpiece can be subjected to an atmospheric-pressure plasma treatment and/or plasma discharge on a side facing away from the high-voltage electrodes inducing the plasma discharge.This is a method for continuous atmospheric-pressure plasma treatment and/or plasma coating of electrically insulated workpieces, in particular boards or sheets of material in which a workpiece to be treated is arranged at a distance beneath at least one high-voltage electrode extending across the direction of movement over at least the width of the surface of the workpiece to be treated, and the electrode and the workpiece are set in motion in relation to one another in a direction of movement, a high voltage being applied to the high-voltage electrode, preferably in the form of an a.c. voltage, which is characterized in that a first space situated between the high-voltage electrode and the workpiece is filled with a first atmosphere and a second space on the side of the workpiece facing away from the high-voltage electrode is filled with a second atmosphere that is different from the first atmosphere, said space being adjacent to the back side of the workpiece, the choice of high voltage and of the first and second atmospheres being made in such a way that a plasma discharge is ignited in the second atmosphere.
摘要:
Disclosure of an electrode arrangement (1) as high voltage electrode for continual plasma treatment or plasma coating of web material with several knife electrodes (3) arranged at a right angle to any transport direction of the web material and essentially located parallely to each other which is characterized by the fact that the distances (a−e) of adjacent knife electrodes (3) vary. In tests it has turned out that a more uniform coating result or, respectively, treatment result can be achieved with such an electrode arrangement than with comparable arrangements in which the knife electrodes are arranged equidistant. Preferably, the distances (a) between adjacent knife electrodes (3) are larger at the edges of the electrode arrangement (1) than the distances (e) between adjacent knife electrodes (3) in its center.
