  • Storing data for re-measurement of objects using a recording machine vision system
    Patent number: 10012500
    Abstract: A method and a system for the quality control of objects after they have been supplied. After manufacturing, the object is checked by means of a measuring machine vision system. The measurement results of the machine vision system are recorded in a data system together with the corresponding calibration data. When the calibration data is known, new measurements can be conducted later from the recorded images at a time when the actual object has already been supplied and possibly placed in an end product.
    Type: Grant

  • Method and system for optical measurement of the shape of an article
    Patent number: 7733503
    Abstract: The present invention relates to a method and system for measuring articles made of a material that is difficult to measure, such as glass. In the system, an elastic film (19) is arranged on top of an article (110). A number of measurement points have been arranged on the film that are imaged using a machine vision system. The location of the measurement points imaged are calculated with respect to one another, and based on this, the shape of the article can be measured.
