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.
