Description
Technical field
The utility model relates to the planar bar code technology field, and particularly a kind of physical dimension is adjustable, can show the letter symbol with certain meaning, with the two-dimentional genuine knowledge sign indicating number of the needs that adapt to different occasions.
Background technology
Two-dimension code (2-dimensional bar code) is (on the two-dimensional directional) distributes on the plane according to certain rules with certain specific geometric figure a chequered with black and white graphic recording data symbol information; On coding, utilize " 0 ", the notion of " 1 " bit stream that constitutes the computer-internal logical foundations dexterously, use several and the corresponding geometrical body of scale-of-two to represent the literal numerical information, automatically handle with realization information by image input device or photoelectric scanning device automatically identifying and reading, have function that different rows is discerned automatically simultaneously and handle characteristics such as image rotation change.Therefore two-dimensional bar code can express a large amount of information in horizontal and vertical two orientation while expressing information in very little area.
In present tens kinds of two-dimensional bar codes, code system commonly used has: the PDF417 two-dimensional bar code, the Datamatrix two-dimensional bar code, Maxicode two-dimensional bar code, QR Code, Code 49, Code16K, Code one, etc., except these common two-dimensional bar codes, also have Vericode bar code, CP bar code, Codablock F bar code, field character code, Ultracode bar code, Aztec bar code, LP Code, wing sign indicating number etc.
These two-dimension codes, the high density coding, information capacity is big: but 1850 capitalizations of outfit as many as or 2710 numerals or 1108 bytes, or more than 500 Chinese character, higher approximately tens times than common bar code information capacity; Coding range is wide: this bar code can digitized information be encoded picture, sound, literal, signature, fingerprint etc., shows with bar code; Can represent the multilingual literal; But presentation video data; Fault-tolerant ability is strong, has error correction: this makes two-dimensional bar code because of perforation, stained etc. when causing local damage, can correctly obtain recognition in the same old way, but damaged area reaches 50% recovering information still; The reliability of decode height: it is more much lower than common bar code decoding error rate 2/1000000ths, and the bit error rate is no more than 1/10000000th; Simultaneously can introduce encryption measures: confidentiality, antifalsification are good; Cost is low, easily makes durable; Bar code symbol shape, size variable-scale; Two-dimensional bar code can use laser or the recognition of CCD reader.
In a lot of practical applications of two-dimensional bar code, because the space that permission can be printed is very limited, so not only require two-dimensional bar code that higher information density and higher information capacity are arranged, and require the profile length breadth ratio of two-dimensional bar code adjustable, can change the profile of two-dimensional bar code, to adapt to the needs of different occasions.
More than stipulate the method that fixed mode coded message is distributed in coding region, can't regulate the profile length breadth ratio of two-dimensional bar code arbitrarily, so all in the world two-dimensional matrix bar codes all are square basically at present, and only provide limited several different big or small patterns to use for the user, limited the range of application of two-dimensional matrix bar code so widely.
The utility model content
For this reason, the problems referred to above to be solved in the utility model, a kind of two-dimentional genuine knowledge sign indicating number is provided, this two dimension genuine knowledge sign indicating number can not only meet the specific (special) requirements that the Error Correction of Coding algorithm is arranged in coding region to the square matrix code coded message best, the special character symbol that can also now have certain meaning in symbol outward appearance upper body, and realized the continuous setting of two-dimensional matrix code, and had and to a certain degree resist the stained ability of frame the profile size.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of two-dimentional genuine knowledge sign indicating number, this two dimension genuine knowledge sign indicating number are the quadrate array that square modules constitutes, and comprise data field, view finding figure, positioning pattern, check block and the clear area of three data information area.
The view finding figure comprises housing view finding figure and symbol view finding figure; Housing view finding figure is that housing view finding figure is that a recessed rectangle in the angle of standard picture, width are the dark housing of 1 module; Described symbol view finding figure is 1 dark symbol figure, is arranged in angle of described housing view finding figure in the recessed rectangle, and its outermost edge and described housing view finding figure form square;
The clear area is a light color, is arranged on the outside of view finding figure; Be the clear area of a module width between housing view finding figure and square array column border; Minimum spacing between described housing view finding figure and symbol view finding figure is a module width;
Positioning pattern is the capable positioning pattern and the row positioning pattern of a module width, alternately is made up of the light module of dark color, is arranged in the housing view finding figure; Row positioning pattern and row positioning pattern all start from the module of housing view finding figure indent corner, run through in the housing view finding figure.
The data field is arranged in the housing view finding figure, is divided into three data information area by positioning pattern;
Check block is arranged in three coded message districts one;
Two dimension genuine knowledge sign indicating number be the quantity of module on limit of a quadrate array constituting of square modules for greater than the even number that waits 16, large information capacity is big more more, but generally is not more than 64;
The row positioning pattern is light module with the module that the module of housing view finding figure indent corner is connected all with the row positioning pattern;
Check block is that 2 modules arranged side by side are formed.
Two-dimentional genuine knowledge sign indicating number of the present utility model, comprise two different view finding figures in the view finding figure, the possibility that runs into similar two figures simultaneously is minimum, therefore can in the visual field, promptly discern possible genuine knowledge code sign, discern two view finding figures, can determine the position and the direction of symbol in the visual field clearly; Positioning pattern is determined the density of symbol module, and the reference position of decision module coordinate is provided; Data information area can be according to concrete applicable cases, and multiple coding application modes such as character pattern, alphanumeric pattern, byte mode, mixed mode can also be introduced error correcting code, mask technique etc., and quantity of information is very big.
Technique scheme of the present utility model has the following advantages compared to existing technology: this two dimension genuine knowledge sign indicating number can not only meet the specific (special) requirements that the Error Correction of Coding algorithm is arranged in coding region to the square matrix code coded message best, simplified the coding/decoding program significantly, the special character symbol that can also now have certain meaning in symbol outward appearance upper body, and realized the continuous setting of two-dimensional matrix code to the profile size, the scope of application is extensive.
