Definitions

  • the present invention relates to an optically readable etiquette containing encoded information in a first pattern.
  • Etiquette in this context means etiquettes in ordinary meaning as well as part of wrapping, container, punched plate etc.
  • Optically readable etiquettes of many kinds are known, firstly such that contain an encoded information in the form of a number of bars of different widths with varying distances, intended to be read in one dimension. Recently, a number of suggestions for two- dimensional , optically readable etiquettes have been presented, containing encoded information in different forms. In automatic handling of goods it is difficult to read codes in the form of bars, that is to say bar codes, as the bars must be relatively narrow regarding reasonable information density. Furthermore, it is difficult to arrange the reading such, that the etiquette is located in a correct position for reading. A code, arranged in two dimensions enables a more safe reading.
  • a known such code is the american Automatic Identification Manufacturers Uniform Symbol Description- 5, called USD-5, comprising a number of rectangles, arranged in relatively widely spaced columns and lines against an optically contrasting background.
  • This code contains a limited information amount per area unit, that is to say, it utilizes the available information area relatively poorly.
  • the object of the present invention thus is to achieve an optically readable etiquette of the art mentioned introductorily, that enables large information density per area unit, but that is easily located and safely readable, even if it is surrounded by a large amount of optically readable information or an optical disturbance.
  • such an etiquette is primarily characterized in that the etiquette in connection with the first pattern also comprises at least one second pattern for locating the first pattern, which second pattern consists of a number of figures, optically diverging from the background, arranged with equal mutual distances along two coordinate directions, that preferably form a right angle with each other.
  • the etiquette can be located with electronic filtering technique, known per se, for instance by 2- dimensional Fourier analysis.
  • the etiquette also comprises a third pattern of the same type as said second pattern, the second and the third patterns being arranged symmetrically on either side of the first pattern.
  • the first pattern comprises a numeber of rectangles arranged mutually orthogonally, bordering with their sides on each other, the rectangles showing at least two different optical properties.
  • a first pattern is referred to by 1. It consists of a number of black and white squares 2,3 arranged in an orthogonal pattern, bordering with their sides on each other, and together giving the desired code.
  • a second pattern 4 and a third pattern 5 are arranged, symmetrically.
  • These second and third patterns are, in the shown example of an etiquette according to the invention, identical, and consist of a number of squares 8, that do not however, border on white squares, which is the case for the first pattern.
  • the second and the third patterns have as an object to make possible or to make easier the locating the first pattern and furthermore to give the coordinate directions and scale of same.

Abstract

L'invention se rapporte à une étiquette pouvant être lue optiquement contenant des informations codées dans une première configuration (1). Cette étiquette se caractérise en ce que, en connexion avec la première configuration, elle comporte également au moins une seconde configuration (4) permettant de localiser la première configuration (1). La seconde configuration se compose d'un nombre de motifs, divergeant optiquement du fond, disposés à des distances mutuelles égales le long de deux axes de coordonnées formant de préférence un angle droit l'un par rapport à l'autre.
