Abstract
The invention discloses a method for identifying object on the basis of two-dimensional lattice codes, belonging to the field of object identification. The invention provides that four small original points distributed on, below, on the left and on the right of a grid crosswire on an N*N grid (N is more than 4) represent four different data; for an N*N grid, 4N*N different combinations can be generated so as to represent a great quantity of data. Because lattice granularity adopted by the invention is small and has small possibility of copying and a great quantity of data can be identified in limited area space, objects can correspond to lattice codes one by one so as to expand the application of two-dimension codes on identifying objects.
Description
Technical field
The invention provides a kind of method that identifies article, be specifically related to a kind of method, belong to the article mark field with two-dimensional points horizontal and vertical parity check code marker product.
Background technology
Two-dimension code be with certain specific geometric figure by the chequered with black and white graphic recording data symbol information of certain rule in plane distribution, handle automatically with realization information by image input device or photoelectric scanning device automatically identifying and reading.
Existing two-dimension code is divided into stack and matrix form.Be to be piled up by the multirow bar code to form on the stack two-dimension code form, representational stack two-dimension code has: Code 16K, Code 49, PDF417 etc.The matrix type two-dimension sign indicating number is to encode by black, the different distributions of white pixel in matrix at a coffin.On matrix respective element position, black " point " expression " 1 " appears, and " point " expression " 0 " does not appear deceiving, and " point " permutation and combination on matrix is determined the meaning of matrix type two-dimension sign indicating number representative.Representational matrix two-dimensional barcode has: Code One, Maxi Code, QR Code, Data Matrix etc.
Two-dimension code generally is used for the application of aspects such as list, safe and secret, tracking, license, stock taking.Some two-dimension codes are used for identifying Individual Items, as DataMatrix, QR Code.The single product bar code of Citizen management to " I.D. " on the watchband is typical case's application of two-dimension code sign article, as shown in Figure 1, its principle of work is: illustrated marque, make number, produce two-dimension code after the identifying code information encryptions such as (plain codes), identify this Individual Items with this two-dimension code.
At present, there are two problems with two-dimension code sign article, the one, identification code can easily duplicate and utilize, and the 2nd, need encrypt the generation two-dimension code during owing to the sign article, then the password of different product, different manufacturers is managed separately, causes being difficult for forming unified article mark and verification platform.
Summary of the invention
The purpose of this invention is to provide a kind of new coded system, make in following data area that can identify of bar code area condition of limited very big, thereby can accomplish that an one number and Individual Items are corresponding one by one, identification code is not easy to be replicated, can to form unified article mark and verification platform simultaneously.
Technical scheme of the present invention is as follows:
A. the present invention adopts two-dimensional lattice to come identification data, and the form of two-dimensional lattice is (Fig. 3 is the partial enlarged drawing of Fig. 2) as shown in Figure 2.Two-dimensional lattice is formed (N for greater than 4 integer) by N * N point, and (grid distance is 0.2～1mm), puts on each grid 4 different station location markers minute up and down, and combination can produce 4 on the square net of N * N
N * NIndividual different two-dimensional lattice.
B. the formation of two-dimensional lattice home block:
The two-dimensional lattice home block is made of one or more different two-dimensional lattices.In order to accomplish only just can to pick out different two-dimensional lattice home blocks, make the two-dimensional lattice in the different two-dimensional lattice home blocks not repeat from local dot matrix.Any two-dimensional lattice in the two-dimensional lattice home block is all represented this two-dimensional lattice home block.
For the ease of distinguishing different two-dimensional lattice home blocks, can come different two-dimensional lattice home blocks is distinguished with special monumented point or space.For example: the point in the center of specifying grid is a monumented point, and (up and down) each how many bar wire gauges are decided to be same two-dimensional lattice home block around it.Perhaps capable and i row point or space (0＜i＜3) are cut apart with i, and cut-point is identified on the position up and down of grid.
C. the formation of two-dimensional points horizontal and vertical parity check code:
The two-dimensional points horizontal and vertical parity check code is made of one or more two-dimensional lattice home blocks.In order to distinguish different article, make all two-dimensional points horizontal and vertical parity check codes not repeat.
D. the article mark of two-dimensional points horizontal and vertical parity check code:
On article that will identify or article packing medium, this two-dimensional points horizontal and vertical parity check code identifies this article like this to become the two-dimensional lattice code system label to attach (or directly printing), and the two-dimensional points horizontal and vertical parity check code is corresponding one by one with article.
E. the identification of two-dimensional lattice home block:
The two-dimensional lattice home block is input to as after on the medium of papery class, scanning device with the band high-definition camera obtains two-dimensional lattice image on the two-dimensional lattice home block, and the machine analyzing and processing can obtain all or part two-dimensional lattice that comprises in this two-dimensional lattice home block as calculated.
Beneficial effect of the present invention: because the dot matrix granularity that the present invention adopts is very little, can identify very many data in limited area space, it is corresponding one by one with the some horizontal and vertical parity check code to satisfy article, thereby has expanded the application of two-dimension code aspect the sign article greatly.

Embodiment
The present invention is described further below by example, but it should be noted that, the purpose of publicizing and implementing example is to help further to understand the present invention, but it will be appreciated by those skilled in the art that: without departing from the spirit and scope of the invention and the appended claims, various substitutions and modifications all are possible.Therefore, the present invention should not be limited to the disclosed content of embodiment, and the scope of protection of present invention is as the criterion with the scope that claims define.
For the example of sign article, the dot matrix with 6 * 6 adopts format identification (FID) article as shown in Figure 4, and each lattice block of 6 * 6 can identify 4 at most
36=4.7 * 10
21Individual different article, if each identifies national code, production firm's sign indicating number, goods categories sign indicating number, article sequence code respectively with a lattice block, the length of side of supposing each grid is 1mm, then in the area space of 24mm * 6mm, can identify 4
36Individual country, 4 of each country
36Individual manufacturer, 4 of each manufacturer
36Individual goods categories, 4 of each goods categories
36Individual article can identify 4 at most
36* 4
36* 4
36* 4
36Individual different article can accomplish that article and identification code are corresponding one by one in limited area space.
