  • Method and device for determining a three-dimensional distortion
    Patent number: 10289895
    Abstract: A method for determining a distortion of the image of an object formed by a reflection on a reflecting object includes capturing a reflected image of the reflecting object, determining, using the captured reflected image, a three-dimensional (3-D) shape of the surface of the reflecting object, calculating, based on the determined 3-D shape, distortion of the captured reflected image of the reflecting object from different viewing directions and using the calculated distortion from the different viewing directions, determining a three-dimensional (3-D) distortion of the surface of the reflecting object.

  • Method for determining a local refractive power and device therefor
    Patent number: 9818021
    Abstract: A method for determining a local refractive power in a volume element of a transparent object using a pattern includes observing the pattern through the transparent object by a first camera, determining, using the observed pattern, a three-dimensional (3-D) shape and position of a surface of a particular volume element of the transparent object facing the pattern and using the determined 3-D shape and surface position of the particular volume element, determining a local refractive power for the particular volume element.
