Method and apparatus for identifying information contained in surface deviations |
摘要 |
An apparatus for identifying information contained in deviations in the surface of an article, such as aluminum cans, glass bottles, and plastic bottles, has a source for radiating the article to provide a reflection from the deviations. An observing device observes the deviations in the reflection characteristics. A computer algorithm identifies the deviations and determines whether they correlate to a known pattern of surface deviations. The deviations are in the form of a plurality of lines having a predetermined uniquely identifiable spacing, providing a pattern which may be easily detected by its reflection characteristics and compared to a known pattern of surface deviations. The plurality of lines may be arcs orientated relative to a point on the surface of the article to provide an origin for the arcs, thereby permitting the article to be rotated about its origin for easy location and measurement.
