Abstract

L'invention concerne un procédé et un dispositif de détermination de la morphologie (M) d'un matériau divisé, en particulier d'un granulat, ledit matériau divisé étant composé d'au moins une particule, qui permettent :- de projeter une ombre de ladite particule ayant un contour (26),- de déterminer les coordonnées (C) des points (26i) dudit contour (26),- de traiter lesdites coordonnées (C) pour approcher ledit contour(26) par une pluralité de segments consécutifs (32i, 32i+1), et- de déterminer un critère de morphologie (M) dudit matériau divisé par un traitement des positions relatives d'au moins deux desdits segments consécutifs (32i, 32i+1).
