Assessment of animals and carcasses

摘要

A method of assessing an animal or carcass comprises: projecting at least one line onto the animal or carcass by non-uniformly illuminating the animal or carcass, the line is projected onto the animal or carcass from a first direction; detecting at least part of the projected line using a detector which detects the line from a second direction, the second direction being different from the first direction; and assessing the body composition of the animal or carcass using the relative positions of at least two spaced apart points on the line.
