Abstract
A three dimensional coding method is using a tree-dimension coordinate to indicate a code unit, the name and direction of the coordinates may be determined arbitrarily and scalenunbers may be expressed in any axis or implicated it grey scale. For example, the characteristics of the information are coded by coding unit constructed by X axis as scale number, Y axis as a bit number and 2 axis as a grey scale or its color. The carrier could be paper, plastic or the surface of the metal. Above said code can indicate the layer height of the three dimension space according to the definition of the grey scale and the colour. The present invention may find its application in the fields needing security and antifake.
Description
The present invention relates to a kind of three dimensions notion of utilizing and carry out Methods for Coding.
The various codings that use in every field at present have a lot, and the common issue with that these codings exist is that these encode contained eigenwert very little.In the face of the 21st century of information explosion, human needs's record and the information of handling are more and more, and traditional coding method is the incompatibility development of modernization more and more.Earlier 1990s, two-dimensional encoded method is arisen at the historic moment, as the PDF417 sign indicating number of the U.S..But face the growth that current quantity of information is geometric series, it is big inadequately that traditional one-dimensional linear sign indicating number (bar code) and two dimensional surface sign indicating number (PDF417 sign indicating number) still show its information capacity.For this reason, China Patent Office has accepted in the recent period that application number is 00104559.8, denomination of invention is the patented claim of " three-dimensional code encoding method of arbitrary carry system ".
At the deficiency of " three-dimensional code encoding method of arbitrary carry system " technology, the present invention gives prominence to and has explained a kind of notion of utilizing gray scale (or claiming black density) expression three dimensions floor height.This coding method has same convenience with traditional coded system when utilizing electronic system to discern.
The present invention is the theory based on " three-dimensional code encoding method of arbitrary carry system ", is primarily characterized in that to introduce to utilize gray scale (or claiming black density) the three-dimensional floor height of expression and encode.Three-dimensional floor height described in " three-dimensional code encoding method of arbitrary carry system " is to utilize the notion of the definition of color being represented the three dimensions floor height, and because of color only is the very little category of the greyscale concept next one, obviously gray scale (or claiming black density) has contained color.The three dimensions notion is meant the notion of introducing Descartes's three dimensional space coordinate system, be that any point in the space all can be described by the parameter of X-axis, Y-axis and Z axle respectively, promptly on by the basis of the two dimensional surface sign indicating number that X-axis and Y-axis determined, introduce the notion of Z axle floor height, thereby make code capacity that the raising of geometric series be arranged.Today that coding of the present invention is popularized day by day for computing machine, video camera, scanner and other IT product, make the rapid generation and the identification of coding become possibility.But this encoded carrier is the material of paper, plastics or metal surface and other record coding.
Further illustrate the present invention below in conjunction with accompanying drawing.
Fig. 1 is the present invention represents floor height with gray scale a structural representation.
Explain this coding under cartesian coordinate system: what X-axis was described is the system number, and what Y-axis was described is the figure place of this coding, and the coding of this moment has become the two dimensional surface sign indicating number.If the gray scale of coded message point is divided into 256 gray levels (also can be divided into more gray level), these 256 gray levels are divided into the H section as required, each section is represented one deck (see figure 1), can increase one dimension Z axle again, and wherein floor height is H.By this coding method, arbitrary information characteristics must be decided by X-axis (system number), Y-axis (figure place) and Z axle (floor height).In other words, we can obtain H layer plane sign indicating number altogether, but it is again to print in one plane, so be called three dimensions notion sign indicating number or gray scale plane sign indicating number.
Relative two dimensional surface sign indicating number, three dimensions notion sign indicating number has had the increase of geometric series again on information capacity.
The present invention can use in various needs to be keep secret and key areas such as false proof, encodes as various certificates, written historical materials, chart and photo figures data.Except that specially designed electronic recognition system can be decoded, other people were difficult to crack this coding.
In sum, adopt the three dimensions notion that information characteristics is encoded, make the eigenwert of codified raising significantly arranged again, and can adapt to the identification of computing machine especially than two-dimension code.Obviously the present invention is the new invention of a kind of novelty, progress and dark tool practicality.
