Abstract

Les quatre coins de feuilles en cours de transfert sont photographiés au moyen de quatre appareils photo à analyseur à transfert de charge et quatre flashs orientés chacun avec un angle donné par rapport à l'axe optique d'un appareil photo. Chacune des quatre sections de détection de coin détecte les coordonnées absolues d'un coin en se basant sur les différences de luminosité des images fixes des coins des feuilles prises par les appareils photo. Puis, en utilisant les coordonnées absolues obtenues pour les coins des feuilles, une section de calcul des dimensions des feuilles calcule la longueur, la largeur et la diagonale des feuilles.
