Article inspection system for analyzing end and adjacent sides |
摘要 |
An article inspection system especially useful for containers having threaded ends includes a video camera, digitizer and data processor operable to analyze a video image collected through a lens system. The lens system has several alternatives, in each case including a wide aspect object lens, wider than the end of the article being inspected, with a refracting and/or reflecting light ray path operable to produce a two dimensional image including both the end of the article and the sides of the article adjacent the end. The optics produce a distorted image in which the sides of the article appear folded upwardly into the two dimensional image such that a two dimensional data array adequately represents the image of the end and the adjacent sides.
