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.

A method for determining a distortion of the image of an object formed by a reflection on a reflecting object, the method comprising the steps of:
- capturing a reflected image of the reflecting object;
- using the captured reflected image, determining a three-dimensional (3-D) shape of the surface of the reflecting object;
- based on the determined 3-D shape, calculating 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.
A device for determining a three-dimensional (3-D) distortion of an image captured as a reflection on a reflecting object, comprising:
- a camera for capturing the image of the reflection on the reflecting object;
- a determination device for determining, from the captured image of the reflection on the reflecting object, a three-dimensional (3-D) shape of a surface of the reflecting object;
- a computing unit for calculating, on a basis of the determined shape of the 3-D shape of the surface of the reflecting object, a distortion of the captured image from different viewing directions and according to the calculated distortion from the different viewing directions, calculating a three-dimensional (3-D) distortion for the surface of the reflecting object.
