Detailed description of the invention
Fig. 1 is a kind of flow chart of two-dimensional code generation method containing background image provided by the invention.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to the scope of the present invention.
It can not achieve quick, high success rate image in 2 D code parsing in view of existing method, the embodiment of the present invention provides
Two-dimensional code generation method and equipment of the kind containing background image.
Embodiment one
The present embodiment provides a kind of methods of fast resolving image in 2 D code, as shown in Figure 1.
Script two dimensional code light color point is not disturbed in order to prevent, and during realization, the present invention will not be to two dimensional code light color
Background process is done at point.The influence of Background is not will receive at two dimensional code light color point.Due to above-mentioned setting, in resolving
In, all points with color and the light point without color can be distinguished clearly after gray proces.It is all
In resolving, the case where being interfered, is substantially reduced, and analyzing efficiency improves.
Two dimensional code generally all have passed through the processing of mask plate, so dark color point is certainly much larger than shallow for two dimensional code itself
Color dot, even when being not processed to light color point, the pattern at dark point is also enough to show background.Therefore, background patterns is in
It is now without a doubt certainly.Special envoy is directed to for highdensity two dimensional code, its higher background patterns of density will be more complete
Obviously.The two dimensional code of above-specified high density refers to that the points of two dimensional code in per square centimeter reach 300 or more.
The method process is as follows:
Collecting data information and background picture:
Acquisition needs to be input to the data information in two dimensional code, and needs the background picture with two dimensional code integration.
Above-mentioned background picture may include picture photo, logo, text, signature, seal etc..Background picture can be used for office
Portion's two dimensional code background, or whole two dimensional code backgrounds.A part of background picture can also be taken as two dimensional code background.
Data information is converted into coded data:
Data information is usually to have number, character, symbol composition.It needs for data information to be converted into be used directly for shape
At the binary coded data of two dimensional code.
According to background image and two dimensional code size, color matrices are obtained:
The size of two dimensional code can be by preset fixed dimension, and be also possible to be determined according to coded data can be with
Accommodate the size of the two dimensional code of all data.
Background picture is pre-processed, and treatment process can be through two dimensional code size, in any position of background picture
Set the figure for intercepting identical size.It is also possible to zoom in and out background picture to adapt to two dimensional code size.
By the background picture after processing, then corresponding two dimensional code matrix, the corresponding each pixel of two dimensional code matrix is obtained
The color-values of point, finally form color matrices.It is noted herein that if the position put on two dimensional code matrix corresponds to background
Color on picture is needed by the point record of the position in color matrices or labeled as light gray for white.
According to encoded information and color matrices, the two dimensional code with background is formed.
During forming the two dimensional code with background, if coded data is 1, corresponding data point is original on two dimensional code
It should be black or dark color, but in the present invention, the color needs of the point are determined according to the color of corresponding points in color matrices
It is fixed.If coded data is 0, next point is directly drawn.It, will when due to being white point in previous step, on background picture
Point in color matrices is labeled as light gray.So when coded data be 1, and the corresponding background picture of point be white point when,
In final two dimensional code is drawn, which is light gray.The setting can be to avoid dark data points are influenced due to background
For white data point, two dimensional code parsing time-consuming or failure are eventually led to.
Relative to the mode for directly putting background base map under two dimensional code, the two dimensional code background patterns that this method is formed will more
Add full, effect is cleaner and tidier.
In conclusion the method and device for the fast resolving image in 2 D code that the embodiment of the present invention provides, has following
The utility model has the advantages that
(1) processing mode of the background picture in the present invention, it is possible to reduce the pollution of data point on two dimensional code improves two dimension
Code analyzing efficiency；
(2) the two dimensional code background forming method in the present invention, so that image seems fuller clean and tidy.
Particular embodiments described above, to the purpose of the present invention, technical scheme and beneficial effects have been carried out further in detail
Describe in detail it is bright, it should be understood that above is only a specific embodiment of the present invention, the protection model being not intended to limit the present invention
It encloses, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
