A method and an apparatus are disclosed for the objective determination of the conformation and fatness classes and other quality properties of individual cattle carcasses. A carcass (19) or half of a split carcass (19c) is placed in a lightscreening chamber (1) in front of a light-emitting, contrasting surface (13), and while the carcass (19, 19c) stands out as a dark silhouette against the contrasting surface, a picture of one entire side of the carcass is registered with a video camera (18). The contour of the carcass is determined by processing the registered picture in a data processing system. On the basis of the determined contour a calculation of the parameters is performed in the data processing system and the classes and other quality properties of the carcass are determined and the result is displayed or printed. The apparatus comprises a light-screening chamber having a lightemitting, contrasting surface (13) and means (7,8,9) for placing the carcass in front of the surface. A video camera (18) is facing the surface registering a picture of the carcass while it stands out as dark silhouette against the surface. A data processing system determines the contour by processing the registered picture. This system calculates the classes and other quality properties of the carcass, and the result is displayed or printed. The classes of conformation and fatness may be determined with sufficient accuracy to replace the subjective classification performed by a classifier. |
