Abstract
The invention concerns a process and an apparatus for automatic inspection of transparency contrast, consisting of illuminating the body of a container transversely to its axis (8), placing the container (3) against the light simultaneously with the aid of two charge transfer cameras, the sighting axes (11) of which are off-set angularly, of eliminating with the aid of an electronic window appropriate for each type of container, all signals originating in elementary points of the photosensitive matrix devices of said cameras (10) located outside the window, of analyzing successively each elementary point of the window by taking into account a predetermined number of immediately surrounding elementary points, of comparing the electric level of each elementary point weighted in this manner with a reference level pre-established for each type of container and of actuating the rejection of the container being inspected when the number of elementary points detected out of reference is higher than a predetermined number. Application in particular to the inspection of bottles.
