Description
Technical field
The present invention relates to areas of information technology, refer to especially sign and its implementation of a kind of three-dimensional code.
Background technology
Along with high-tech develop rapidly, people are studying how to change the manual data input always, improve input quality and input speed.In the later stage forties in last century, two slip-stick artist Norm Woodland of the U.S. and Bernard Silver have invented the automatic identification equipment with the coded representation food item, and have obtained United States Patent (USP) in 1949, and this also is barcode technology patent records the earliest.Be limited to the at that time restriction of typography, this technology is not widely applied.
Until the seventies, U.S.'s supermarket committee system is made universal product code (UPC code), and barcode technology just progresses into the commercial fields such as retail trade, stock control.1973, the U.S. Unified coding council (UCC) to the standardization of UPC coding so that barcode technology has entered flourish period; And developing of European ibs encoder (EAN) further impels barcode technology to become gradually the business language that a kind of Global Access is used.
The eighties, the researcher has developed the higher one dimension code (One-Dimensional Bar Code) of some density in succession, such as EAN128 code and 93 yards.All begin to use on a large scale the one dimension code this period both at home and abroad, and application comprises Package Management, logistics management etc.Domestic most typical application has supermarket cash register scanning and medicine prison code.The application of one-dimensional bar code can improve the speed of Data Enter, reduces error rate, and the part but one-dimensional bar code also comes with some shortcomings: data capacity is less: about 30 characters; Can only comprise letter and number; Bar code size relatively large (space availability ratio is lower); After being damaged, just can not read bar code.
In order to solve the deficiency of traditional bar code, invented two-dimensional bar code in the nineties in 20th century.Two-dimensional bar code is except the advantage with bar code, and the advantage such as contain much information, reliability is high, security and antiforge purpose is strong in addition.Since U.S. Symbol company in 1991 releases the PDF417 two-dimensional bar, several more successful two-dimensional bars have been carried out in the whole world, wherein the PDF417 of the U.S., by the Denso Wave of subsidiary company of Japanese Toyota in the QR code of invention in 1994, be most widely used by the U.S. international data company (International Data Matrix is called for short ID Matrix) invention DM code in 1989.
Along with the further popularization that bar code is used, people have higher requirement to the information capacity of bar code, wish that bar code can pass the more information of carrying, and this moment, the information capacity of two-dimensional bar code can not meet the demands.In theory, we can adopt to increase barcode size or increase bar code density and solve this problem, but these two kinds of solutions have certain limitation.Increasing barcode size needs the bar code carrier that larger printing area is provided, and often in the occasion of practical application, the size of bar code is had very strong restriction, for example restriction of certificate, the size of document own, the too large printing area that can not provide to bar code; And the increase bar code density needs printed apparatus, recognizing apparatus that higher precision is arranged, and cost is high, and increases the antijamming capability that bar code density can obviously reduce bar code, has greatly limited the environment that bar code is used.Such as, the max cap. of existing two-dimension code is no more than the 3.7K byte, and corresponding Chinese character is no more than 1800 Chinese characters, and along with the increase of carrying content, under the fixed physical size, the image resolution-ratio of two-dimension code requires very high, is unfavorable for the video acquisition of commonly using.
Under this background, on the basis of two-dimension code, the professor Tack Don Han of Korea S Univ Yonsei Seoul takes the lead in having invented three-dimensional code (Color Code), and has obtained certain application in Japan and Korea S two countries.The foolish stupid academician's of China Inst. of Optoelectronics, Shenzhen Univ. ox team developed " the three-dimensional code of arbitrary carry system generates and recognition system " in 2004, this three-dimensional code is to utilize color or gray scale (or claiming black density) to represent the third dimension, a coding unit size is under the condition of 0.4 * 0.4mm, and every square centimeter can be held the 2.5K byte.2008, Shanghai color code Information technology company limited develops the color code of first generation core system, it is a kind of novel information bar code product that development produces on traditional two-dimension code basis, it is on the basis of conventional planar matrix two dimension, add matrix unit and play up color as new one dimension, consisted of the colour barcode pattern.
No matter be the foolish stupid academician's of ox the color code of three-dimensional code or Shanghai, or Korea S Tack Don Han professor's three-dimensional code (Color Code), during studying successfully till now several years, use on market is also few, main cause is when coming carry information with the difference of color, because it is very high that the identification of color requires outside light environment, and the existence of color management own much is not easy to the factor of industrialization, so obtain at present commercial three-dimensional code application both at home and abroad fully.
