Single-camera multi-mirror imaging method and apparatus for whole-surface inspection of rotating objects

摘要

The single-camera multi-mirror imaging method and apparatus is an inspection system configured to examine a whole surface of a rotating object, preferably a spheroidal object such as a fruit or vegetable. The system includes a plurality of mirrors that direct an image of the inspected object into a digital line scan camera with an associated processor. The processor produces an image of the inspected object showing any detected surface defects and selected contamination on the outer surface of the object.

主权项

1. A defect and contamination inspection system comprising:
a rotating object; a plurality of peripheral image collecting mirrors directed to the object; a central collecting mirror, the peripheral mirrors directing a reflected image of the object to the central collecting mirror; the central collecting mirror comprising a prism-shaped polyhedron having multiple faces so that each of the faces is directed to one of the image collecting mirrors; no more than one camera, the central collecting mirror directing the reflected images to the camera; a processor receiving the images from the camera and producing a concatenated surface image of the object; wherein the inspection system is structured so that the object is retained or rejected based on the image data.
