摘要

A method of and apparatus for inspecting a container having a base and a mouth. Light is directed through the container base into the container, and out of the container through the container mouth, using at least one light source disposed beneath the container base. A plurality of images of the container mouth is obtained from the light transmitted through the container mouth. Minimum bore diameters of the container mouth are calculated from the plurality of images, and an overall lowest minimum bore diameter (OLMBD) of the minimum bore diameters is identified. A value other than the OLMBD is determined to be an effective minimum bore diameter of the container mouth.
