Broken particle e.g. ballast, morphology determining method for use in e.g. railway domain, involves processing relative positions of two consecutive segments that close in contour for determining criterion of morphology of material

摘要

The method involves bringing a broken material e.g. aggregate composed of multiple particles, and projecting a shadow of a particle having a contour (26). Coordinates (C) of points of contour are determined and are processed to close in the contour by several consecutive segments. A criterion of morphology of the broken material is determined by processing the relative positions of two consecutive segments. An independent claim is also included for a device for determining the morphology of a broken material e.g. aggregate, ballast.
