  • System for measuring the surface geometry and surface evenness of flat products
    Patent number: 7489820
    Abstract: The invention relates to a device for producing a pattern on a surface for measuring, using a projector and a slide. The invention also relates to various advantageous embodiments of the measuring system.
    Type: Grant
    Filed: September 7, 1999
    Date of Patent: February 10, 2009
    Assignee: VDEh-Betriebsforschungsinstitut GmbH
    Inventors: Ulrich Muller, Detlef Winter, Detlef Sonnenschein, Rudolf Stockmeyer, Gustav Peuker
  • Method and device for optically measuring the surface shape and for the optical surface inspection of moving strips in rolling and processing installations
    Patent number: 7317542
    Abstract: The invention relates to a method and a device for optically measuring the surface shape and for the optical surface inspection of moving elongated bodies, according to which surface shape measurement and surface inspection are integrated. A projector applies a line pattern to the object to be measured. A camera registers the surface of the object to be measured and compares the image information with a reference pattern. Two high-resolution cameras additionally detect surface defects on the object to be measured. The inventive measuring technique is especially suitable for a combined planarity and surface measurement of metal strips in rolling installations.

  • Flatness measurement system for metal strip
    Publication number: 20050089210
    Abstract: The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.
