Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Before the present invention will be described in further detail, noun involved in the embodiment of the present invention and term are said
Bright, noun involved in the embodiment of the present invention and term are suitable for following explanation.
1) two dimensional code, using certain specific geometric figure according to certain rules in the black and white of plane (on two-dimensional directional) distribution
Alternate graphic recording data symbol information；Composition computer-internal logical foundations are dexterously utilized in code compilation
The concept of " 0 ", " 1 " bit stream indicates text numerical information using several geometrical bodies corresponding with binary system, passes through
Image input device or photoelectric scanning device automatically identifying and reading are to realize automatic processing of information.Two dimensional code has some of barcode technology
General character: every kind of code system has its specific character set；Each character occupies certain width；With certain verifying function etc..Together
When also have to the information automatic identification function do not gone together and the processing rotationally-varying point of figure.
2) code figure can be rectangular code figure or ring code figure, and the code figure includes arranging in certain sequence on the surface,
Rectangular unit modules with different optical signatures；Unit module in the code figure is divided into the macroblock of multiple rectangles.
3) macroblock including storing there is the unit module of the numeric data code word of fixed data length and storage to represent the macro mould
The unit module of Position Number of the block in code figure.The macroblock includes Num × Num unit module, wherein Num be greater than
3 natural number.By taking GM code as an example, Num value is 6, i.e., each macroblock is made of 6 × 6 square shaped cells modules.
4) GM code, also referred to as GM grid code (Grid Matrix Code) are a kind of two dimensional code code systems of square.GM code
It can and offer five user optional error-correction levels a certain amount of with code storage.The priority of the GM code is: superpower fouling resistance
Ability and error correcting capability；Superpower ability of anti-deformation；There is no fatal weakness in figure；Storage volume is big, can believe any computer digit
Breath coding.Therefore under the premise of error-correction level allows, any region is defaced not to affect recognition.As shown in Figure 1, GM code can quilt
360 ° of omnidirectional's recognitions, allow 45 ° of inclination maximum.Here, the datail description in relation to GM code may refer to " Patent No.
The patent document of ZL200410022052.5 ".
Fig. 2 show the structural schematic diagram of the two dimensional code after hollowing out inside the embodiment of the present invention, as shown in Fig. 2, pass through by
It is hollowed out inside one two dimensional code for carving name (be equivalent to and be stained), also an available back-shaped code is used for seal.Such as Fig. 2
Shown, area shared by cut-out can only about account for 40% or so inside the two dimensional code, then high, entangling beyond two dimensional code
Wrong ability leads to not distinguish.In addition, cut-out has occupied most of error correcting capability of two dimensional code, remainder is caused
Error correcting capability it is very weak.For example, using the two dimensional code of 5 grades of error correction, it is 50% that theoretical maximum was allowed, which is stained area, it is assumed that
Inside, which hollows out, accounts for the 40% of the gross area, then remainder theoretical maximum can only be stained 10% again, can not distinguish more than 10%, phase
Weaken significantly when in fouling resistance ability.
It can be seen that there are error correcting capabilities is poor for the direct two dimensional code for hollowing out inside as described in Figure 2, fouling resistance ability is big
The problem of weakening greatly and leading to not recognition.
In order to effectively solve the problems, such as the internal two dimensional code hollowed out in the presence of that can not distinguish, the embodiment of the present invention provides a kind of life

Step 301: the hollow mold of generated code figure；
Here, the hollow mold can be square structure, as shown in Fig. 3 (b).
Step 302: initial position is determined on the hollow mold；
Here it is possible to which any one of described hollow mold macroblock corresponding position is determined as initial position.Certainly,
It, can be by the start bit for the hollow mold there are corner edge for the ease of the subsequent read operation to two dimensional code
It sets at the corner edge determined in hollow mold.By taking square structure as an example, the initial position may include following any one
Kind: the upper left corner, the lower left corner, the upper right corner or the lower right corner.
Step 303: since the initial position, along default orientation by two-dimensional code data stream as unit of macroblock
It is aligned to the hollow mold.
Wherein, all dark unit modules of the frame of the macroblock or all light modules, described two sides
The macroblock of frame is alternately arranged in code figure, and the numeric data code word and number are deposited among the unit module within frame.
Here, the orientation can be for clockwise, or counterclockwise.The hollow mould of the code figure
The number of the macroblock of the initial position of type is default value, the institute by the initial position of the hollow mold of the code figure
The number for stating macroblock is arranged in order.It should be noted that described be arranged in order can be using arrangement incremental in order
Mode, can also be using the arrangement mode to successively decrease in order.
According to an illustrative embodiment of the invention, the initial position can be square the angle of the hollow mold of structure
Play second macroblock corresponding position in edge.
In one example, as shown in Fig. 3 (c), by taking the hollow mold of square structure as an example, by the upper of the hollow mold
Second macroblock corresponding position is determined as initial position from left to right at edge, can be single with macroblock along preset clockwise direction
Two-dimensional code data stream is aligned to the hollow mold by position.
In another example, as shown in Fig. 3 (d), by taking the hollow mold of square structure as an example, by the hollow mold
The 4th macroblock corresponding position is determined as initial position from right to left for top edge, can be with macroblock along preset counter clockwise direction
Two-dimensional code data stream is aligned to the hollow mold by unit.
It should be noted that theoretically, the initial position can be any macroblock pair in the hollow mold
Answer position.
