Description
Technical field
The invention belongs to field of information processing, the generation side of the dot pattern of especially a kind of recordable many bit informations
Method.
Background technology
With the fast development of Computer information network technology, with code, mobile phone recognition and network are the Internet of Things of core
What network technology was making rapid progress flourishes.
In Japan as the up-to-date promising voice data that can directly record larger capacity of two-dimensional bar code, adopt several
The Patent Publication being referred to as lattice codebook of the unconfined combination of code of two-dimensional rectangle dot matrix distribution:" optical readability two dimension
The reading device of bar code " (JP 2005-243047).Although being achieved SoundRec directly in code using this code
On, but because voice data capacity is larger, the Area comparison being indicated causing code with code is big, designed at that time
Identifying device is by sliding over scanning in code, realizing the digital independent of whole code, operability is poor, at that time should
Patent owner puts into huge fund and promotes this technology, but result does not receive the effect of anticipation.
Also can directly record jumbo voice data in a rectangle two-dimensional bar code, and be referred to as " sound code "
Patent is delivered in Japan:" two-dimensional bar code, two-dimensional bar code read method, the record media of program and embodied on computer readable " is (special
Open 2011-198371).This two-dimensional bar code is believed with thickly dotted little dot matrix record using in the square of a rectangle
Breath, recognizer, in the form of contact, can directly read very little dot matrix symbol.This code is mainly used in hospital
And the guide to visually impaired person in public place, therefore referred to as sound code.This code is in the means of record information
Not breakthrough progress, it is still desirable to special space, substantially belongs to the category of conventional code.
For improving the capacity of the record information of two-dimensional bar code, the inventor of Japan has also delivered entitled " color two dimension bar code "
(JP 2006-178692), and the coloured silk of " creating method of two-dimensional color bar code and coding/decoding method " (JP 2011-186613)
The patent of color two-dimensional bar code.The capacity of bar code record information can be improved by colored bar code symbol, but there is still a need for specially
Space, nevertheless suffers from the limitation of code size.Required high speed coding particularly in code application, or low essence
The correspondence spending cheap black-and-white printer is relatively difficult.
Also have a kind of distinctive two-dimensional bar code, be referred to as " color bits bar code ", be also to be delivered by Japanese inventor
, entitled:" optical profile type cognizance code, identifying device and method and program " (JP 2008-287414).This code approximate
Dimension bar code, each symbol can be realized with colored, after importing colour symbolism, in the situation with common bar code identical information
Symbol can be sized for larger down, therefore can read multiple codes with high accuracy photographing unit, particularly when many simultaneously
Individual product pushes and once all of commercial product code can be read in computer during storehouse, is suitable for product warehousing management.But,
It is suitable to but need to do a lot of work in wider code application.
Read two-dimensional bar code for adapting to mobile phone, need two-dimensional bar code more attractive in appearance or the two-dimensional strip with item property
Code, thus has ornamental two-dimensional bar code and arises at the historic moment.Japan occur someone declared entitled:" carry tagged two-dimensional strip
The patent of code " (JP 2009-104451).Even if this code utilizes ordinary two dimensional bar code to destroy a part of region, due to using
Approach of error correction, without the feature of the normal recognition of impact, prints the mark of reflection product features on common two-dimensional bar code
Know.This invention produces certain using value really, but, and it is not belonging to a kind of invention of code form, only one
The application invention of two-dimensional bar code.
Also has a nameless code form as traditional code, referred to as " angle code ".This is also to send out in Japan
The patent of table, entitled " image model of the two-dimensional bar code being read by reading device reading, the presentation medium of map, are read
Take system and read method " (JP 2008-225732).This code carrying out dot matrix distribution with polar form, permissible
Say a kind of another kind of manifestation mode of simply two-dimensional bar code, technological layer with application do not have breakthrough progress,
The current popularization of two-dimensional bar code height and the value further promoted in the standardized epoch of height remain to be discussed.
Since entering 2000, the technology of code occurs in that breakthrough development.Here most important technical characteristic;One is
Code needs occupancy private space by traditional, develops into and is not required to take up room.Two is can only to represent one by a code sign
Individual bit, develops into and can represent many bit informations.Represent this epoch code technique famous patent have several as follows:
Entitled " can achieve the digitized paper the optically reading " (PCT/SE00/ being delivered by the Anoto company of Sweden
01895) international monopoly.This patent proposes can be distributed one about on the basis of the center of imaginary cross hairs
The point of expression information, this represents that the point of information, on the basis of the center of imaginary cross hairs, can be distributed in four about
On individual position, thus can record 4 numerals is 2 bit informations.Can be by full version be printed on paper according to this patent
Dot matrix, realize coordinate information is embedded on paper, write on this paper by the optics recognizer of pen type, can will write
The information such as word are directly inputted in computer.Unfortunately, the benchmark that the inventor of this code is considered is imagination
, in the embedment as coordinate information, it is possible to use close two position of coordinate is a constant, when recognizer moves
When can identify the position of coordinate.But if evaluator is it is impossible to directly know as ordinary two dimensional bar code during point reading
Do not go out code value.
The founder of the Grid company of Japan is found that the defect of the patent of Anoto company of Sweden in time, delivers rapidly
The international monopoly of entitled " method realizing information input and output with dot pattern " (PCT/JP2003/012364).For
There is no the defect of the patent of Anoto company of the Sweden of benchmark dot matrix, exceed the proper limits in righting a wrong to propose and divide on four summits of rectangle
4 benchmark dot matrix of cloth, are referred to as, with this four, the imaginary grid line that grid point connects into a cross, with the imaginary lattice of this cross
It is distributed an information point, this represents the point of information on the basis of imaginary centres on the basis of the imaginary centres that sub-line is formed,
Can be distributed in about on 8 positions, thus can record 8 numerals is 3 bit informations.The founder of Grid company is working as
Shi Feichang excited it is believed that being a marvelous invention, be grid (Grid) company the naming of company unexpectedly.Hardly realize root
This does not need so many benchmark dot matrix, and a datum mark as long as the result of this patent application is taken away is not formed for imagination
Center, cannot be subject to patent protection.In addition it is subject to the shadow of the lifting manipulation of imaginary intersection point in the patent of Anoto company of Sweden
Ring, carried out repeatedly in patent application afterwards substantial amounts of imagination grid, the description of imaginary grid line etc. nihility, this non-
The requirement of wise patent right, even if as a result, being invaded by patent, due to can not obtain favourable proof, make patent application
Attack overshadowed.In addition, though this patent further mentions an information point can record 8 bit informations, but in reality
Limited by sampling thheorem in application, between each position that information point should be distributed, should be had an interval, otherwise easily known by mistake
Not.Information therefore, it is possible to record 2 bits is rational.If obstinately doing so the size that will increase information point, on the contrary can
Appearance information record efficiency is low, and shading gray scale increases the problem of impact picture quality.

Information identification can be made convenient, can timely find the position of macroblock, and code outward appearance is than conventional two-dimensional bar code
Attractive in appearance.But, because each macroblock will arrange border dot matrix, and two neighboring macroblocks will repeat to arrange border
The efficiency of dot matrix, therefore information record is greatly affected.Particularly this two-dimensional bar code is not provided with benchmark dot matrix, depends alone
The identification of code value is realized in the position of information dot matrix, in the application of tax reciept ticket information record, because tax reciept prints using low
The impact printer of precision, therefore occurs the problem of dot matrix dislocation.
Referred to as " Chinese letter co " its outward appearance of committee's proposition is encoded like QR bar code by China, due to being national authority department
The scheme proposing, necessarily has certain application prospect.
There is common problem by the two-dimensional bar code given by Fig. 3 to Fig. 5 is not have security feature, even if commonly multiple
Print machine is all:Can replicate.The present invention proposes to implement false proof process for traditional bar code, makes and has false proof spy
The two-dimensional bar code of property.
Including bar code, two-dimensional bar code is in the interior category broadly falling into anti-counterfeiting codes after false proof process on endowed
's.
Fig. 6 is many bits anti-counterfeiting codes proposed by the present invention.As shown in fig. 6, site 601 is by information point 602 and 603 groups
The anti-counterfeiting codes becoming, represent different information according to the different directions that information point 602 and 603 is constituted.

Antifalsification label, false proof postage, false proof tax paper be can be applicable to by the different many bit informations of shape logger computer
Note etc..Can be by the site of above-mentioned printed article, in the case of the gray scale not changing site, by changing the shape of site, can be in print
One information of brush species record, if this printed article is replicated, point version software that standard is usually used is carried out, and now site will
According to the dot shape given by point version software of standard, the effect originally realizing information embedment by the shape of change site is just
Can lose.Therefore can achieve the effect preventing forging.
Fig. 8 is by the example of the anti-counterfeiting codes concentrating site to be constituted with dispersion site.As shown in figure 8, by a site
In all of printing points constitute the dispersion of the concentrations site a that a dot matrix constituted and at least one scattered site composition
Point b constitutes the example of the fine roots that can imbed information.Concentrating site a to be set as information bit value " 1 ", dispersion site b sets
For " 0 ".On the contrary, can be concentrating site a to be set as information bit value " 0 ", dispersion site b is set as " 1 ".
In addition, in order to constitute standard dot pattern, as shown in figure 8, the high H of point 801 concentrating site a80Print as two
The diameter value of brush point (film micro area), the width W of the point 801 concentrating site a80Diameter as a printing points (film micro area)
Value.The point 802 of dispersion site b functions only as the effect of shading gray scale homogenization, is not used in identification, the height of dispersion site 802
Degree H81With width W81All as the diameter value of a printing points (film micro area).
As shown in figure 8, to be (AM) screen concentrating site a to regard amplitude modulation mode as dispersion site b can be regarded by tune
Frequency mode is (FM) screen.I.e. can be according to the different dot pattern of modulation system come record information.
If x0, y0Non- not Biao Shi the width of site and height, T is the space interval between site, then can with formula below Lai
Represent that AM amplitude modulation screen and PM frequency modulation screen are:
Amplitude modulation screen (site a):
【Formula 1】
By adjusting circular hole functionRadius ε (m, n) realizing Modulation and Amplitude Modulation.
Frequency modulation screen (site b):
【Formula 2】
Wherein ε (m, n) and η (m, n) is in (x0, y0) in the range of (and i.e. in the range of site) adjustment.
By changing ε (m, n) and η (m, n) to change the density of pulse race and frequency modulation(PFM) is realized in position.
In addition, because concentration site a can be regarded as low frequency number site, dispersion site b regards altofrequency number site, institute as
With it may be said that concentrating site a to be composition record information according to different frequency number with dispersion site b, or it may be said that concentrate net
Point a and the quantity record information that dispersion site b is the point according to different sites.
And then, concentrate the gray value of each site of site a big, the gray value of each site of dispersion site b is little, so
That alternatively concentrates the different gray values that site a and dispersion site b is for a point carrys out record information.
In other words, concentrate the size of the point of site a big, size of each point of dispersion site b little it is possible to say concentration
Site a and dispersion site b is come record information according to dot pattern of different sizes.
With regard to above content, can also there are a lot of meanss of interpretation.But if identical with above dot pattern,
Belong within the scope of the present invention.
, prevented by concentrating site to also apply be applicable to antifalsification label with dispersion site logger computer information by shown in Fig. 8
Pseudo- stamp, false proof tax paper note etc..Can be by the site of above-mentioned printed article, in the case of the gray scale not changing site, by concentrating net
Point and dispersion are the distribution of AM screen and FM screen, can lead to if this printed article is replicated in printing one information of species record
Often carried out using point version software of standard, now site will not be to concentrate net according to the site given by point version software of standard
Point is AM screen is exactly the distribution disperseing site both FM screen, originally passes through to concentrate site and dispersion site logger computer information
Effect will lose.Can recognize that commodity true and false using this characteristic, reach the effect preventing commodity from forging.
Fig. 9 is to realize computer many bit informations note by information dot matrix according to the result of different positions and phase-modulation
The schematic diagram of record.As shown in Figure 9:Figure a can represent information 0, and figure b can represent information 1, and figure c can represent information 2

The rectangle field in domain.
By information dot matrix according to the information of the different many bits of location records, have to introduce one according to geometry theory
Reference frame is that is to say, that isolated information point is the solution that can not obtain a position in the space of geometry form, also just not
Its code value can be calculated.One horizontal reference dot matrix and one vertical reference point of setting typically can be set in lattice matrix
Battle array.For reducing the quantity of the point of benchmark dot matrix as far as possible, simultaneously theoretical according to the linear transformation of geometry form, can be in dot matrix
45 degree of angles of matrix only arrange a benchmark dot matrix.
Figure 10 is the information module schematic diagram that the 4*4 dot matrix that cable angle is 0 degree is constituted.
As shown in Figure 10:The principle of 4 diverse location record 2 bit informations according to an information point, can form one
Individual cable angle is the information module of 0 degree of 4*4 dot matrix.In Fig. 10;S11, S22, S33And S44On the basis of dot matrix, S00For spy
Levy dot matrix, S12, S13, S14, S21, S23, S24, S31, S32, S34, S41, S42And S43For information dot matrix, can dominant record 24 bit
Information.Need level with traditional compared with vertical two reference coordinates, the information module being made up of traditional 4*4 dot matrix
The mode that the information of 18 bits can only be recorded compares and increased 6 bit informations.It is additionally, since the information module shown in Figure 10
, on 45 degree, the printing displacement error in level and vertical direction therefore for printer is still reflected in benchmark for benchmark
On dot matrix, still can carry out error correction.Meanwhile, move according to the position of a point on two-dimensional space, inevitable with appoint
The theory of a datum mark linear correlation on meaning position, therefore, omitting one group of benchmark dot matrix can't affect to information dot matrix
The impact of location recognition precision.
The distribution of the diverse location by information point that Fig. 9 and Figure 10 is given, the dot pattern of recordable many bit informations,
It is believed that being the quantity of information obtaining maximum with minimum dot matrix quantity from another angle.As a result, by such lattice mode
The printing shading of formula composition, the printing picture registration with the information that is embedded in, it is possible to achieve the effect minimum to printing image contributions.
Here, Fig. 9 and Figure 10 be to dot pattern, it is also contemplated that printing net screen characteristics, so-called printing net screen characteristics are mainly
Consider three aspects, one is " gamma characteristic of screen site ", be the characteristic, also of the gray scale homogenization of the site instigating screen
It is the characteristic making the printing points of screen site have identical composition, and the characteristic of the gray-value minima of the site of screen.
Two is " size property of screen site ", refers to that the point of whole sites of screen site is the points structure with minimized printing points
The characteristic becoming, and the minimum characteristic of the size of screen site.Three is " interval characteristics of screen site ", refers to screen
Site is according to the characteristic of certain spacing distance arrangement, and the interval of screen site is greater than the spy of the size of screen site
Property.

(2) computerized information code is transformed into the dot pattern of the recordable many bit informations shown in Figure 10, this dot matrix
The point of the baseline network of pattern is on 45 degree of directions of lattice matrix, and the point of information site is by including diverse location
Distribution, the distribution of information point different directions, information point distribution of different shapes, the one kind in being distributed in of information point different distance
Form according to geometry form, or modulate the distribution of (PM) result by including out of phase, the dividing of the different directions of propagation
Cloth, different Mechanics Vectors are distributed in the dot matrix distribution results of interior physicss' form, or by including remembering on minimum area
Record one of a plurality of combined result in the two-dimensional matrix that the symbol of 1 bit information is arranged in form record many bits letter
Breath.
(3) in the range of specified information is imbedded, the dot pattern repeated arrangement of above-mentioned recordable many bit informations is filled
The scope completely specified, constitutes shading image and forms K version.
(4) the above-mentioned printing image imbedding object as information is transformed into by C, tri- editions images being constituted of M, Y, removes
The color of K component, the black of K version is by C, tri- editions synthesis of M, Y.In the case that black component is very heavy if necessary, it is possible to use no
The black ink of carbon containing, if the color of sensation K version is overweight, it is possible to use the light green color of carbon containing, light blue or lurid
