<p>By means of the present invention, it is possible to accurately inspect for obliquity of the top surface of the mouth section of a bottle even if the bottle is tilted or wobbles while being rotated on an inspection platform. Two points (G, H) on the top surface of the bottle mouth are detected from an image of the mouth section captured by a bottle mouth section imaging means, and at the same time two points (M, N) of the bottom end of the bottle are detected from an image of the foot section captured by a foot section imaging means. The tilt of the two foot section points (M, N) is cancelled from the tilt of the two mouth section points (G, H), and thus the top obliquity in the vertical state of the bottle is calculated, resulting in an accurate inspection of the obliquity of the top surface of the bottle mouth section even when the bottle is tilted or wobbles.</p> |
