<p>An image of the filter end surface of a bundle of cigarettes in which a plurality of cigarettes are arranged side by side in the axial direction is captured to obtain an inspection image, and the diameters of the cigarettes in the bundle of cigarettes in the inspection image are each obtained and compared with a reference diameter of a cigarette in the inspection image to determine axial deviations from the bundle of cigarettes (first determination means). In addition, centers of gravity of the end surfaces of the cigarettes are obtained, and axial deviations of cigarettes disposed at both ends of the bundle of cigarettes are determined in accordance with differences in distances between the centers of gravity of cigarettes that are adjacent in the arrangement direction in the end sections and the center section of the bundle of cigarettes (second determination means).</p> |
