Abstract (en)
[origin: FR2852389A1] The method involves determining an optical characteristic of an object. An optical model of visible light propagation across the object is established, where the model has an equation that connects a geometrical parameter of the object to result of an observation made directly on an image of the object. The image is acquired and an observation is performed for determining geometrical parameters of the object.
