Video container inspection with collimated viewing of plural containers

摘要

A video inspection system with collimated viewing of plural containers has a conveyor for continuously transporting bodies disposed immediately adjacent one another to an inspection zone at which the bodies are backlighted. A video detector for capturing and analyzing a digital image of successive containers views the containers through a preferably fresnel collimating lens disposed between the bodies and the video detector, whereby an elevation view of the bodies is achieved. A data processing device operable to correlate the portions of successive images corresponding to a single body proceeding through the inspection zone analyzes the images and operates a downstream apparatus for segregating the bodies based upon visible features.
