Abstract
The invention provides a method for filling a two-dimensional code through an image, and the method comprises the steps: employing a two-dimensional code standard to generate a two-dimensional code image according to to-be-coded information, and enabling a specified image to be placed in the same coordinate system as the two-dimensional code image; filling a data filling region of the two-dimensional code image with pixels at a position corresponding to the specified image, and generating a new image; carrying out two-dimensional code decoding of the new image, carrying out no data error correction in a decoding process, and extracting data codewords, coding version information, and format information; employing a version number in the coding version information, a masking figure in the format information and an error correction level to enable the data codewords to generate a new two-dimensional code image; filling the data filling region of the new two-dimensional code image with the pixels at a position corresponding to the specified image, adjusting the color values of image pixels filled in the data filling region according to the color property of the two-dimensional code at a position corresponding to the filling region, and obtaining the two-dimensional code of the specified image inserted in the data filling region.
Description
Technical field
The present invention relates to planar bar code technology field, be specifically related to a kind of method of image completion Quick Response Code.
Background technology
Quick Response Code, also known as two-dimensional bar code, it is according to certain rules at the chequered with black and white figure that plane (on two-dimensional directional) distributes by certain specific geometric units, in order to record data symbol information, automatically processed to realize information by image input device or photoelectric scanning device automatically identifying and reading.Wherein QR Quick Response Code is most widely used, and it is invented and a kind of matrix two-dimensional code sign brought into use in 1994 by subsidiary company of Japanese Toyota Denso Wave.
Early stage owing to not popularizing internet, the information that Quick Response Code stores is exactly the information that user finally will obtain, the quantity of information stored comparatively speaking is larger, and because early scan equipment performance is poor, in order to make Quick Response Code accurately be distinguished, usually higher level of error correction can be adopted; And current Quick Response Code, be mainly used in storing the index informations such as network address, quantity of information compares less.In addition, along with the lifting of scanning device performance, level of error correction also can adopt lower grade, and the space that error correcting code accounts for is also fewer.Therefore, certain remaining space is had in data area, leave partial fill area, usual fill area is filled code word and is filled, and filling code word had not both had memory encoding information, did not visually pass on any significant information yet, therefore the present invention proposes a kind of method that image completion fill area generates Quick Response Code, so both can improve the space availability ratio of Quick Response Code, also can improve the outward appearance of Quick Response Code, bring user better visual experience.
Summary of the invention
For prior art Problems existing, make full use of picture pick-up device, video procession equipment is fast-developing and the Division identification ability for low error-correction level, low contrast, small size color lump brought, and the feature that 2 D code information amount is little, the present invention proposes a kind of method of image completion Quick Response Code, comprising:
Quick Response Code standard is adopted to generate image in 2 D code, under the image of specifying is placed in described image in 2 D code the same coordinate system according to information to be encoded;
The data stuffing region of described image in 2 D code is specified the pixel filling of image correspondence position, generate new image;
Quick Response Code decoding is carried out to newly-generated image, in decode procedure, does not carry out data error correction operations, extract code word data, version of code information, format information;
Adopt the version number in described version of code information, the mask graph in format information, error-correction level, code word data is regenerated image in 2 D code;
The data stuffing region of described newly-generated image in 2 D code is specified the pixel filling of image correspondence position, adjust according to this fill area correspondence position image in 2 D code color attribute color value to the image pixel inserting data stuffing region, obtain inserting the Quick Response Code of specifying image in data stuffing district.
The embodiment of the present invention adopts Quick Response Code standard to generate image in 2 D code, under the image of specifying is placed in described image in 2 D code the same coordinate system according to information to be encoded; The data stuffing region of described image in 2 D code is specified the pixel filling of image correspondence position, generate new image; Quick Response Code decoding is carried out to newly-generated image, in decode procedure, does not carry out data error correction operations, extract code word data, version of code information, format information; Adopt the version number in described version of code information, the mask graph in format information, error-correction level, code word data is regenerated image in 2 D code; The data stuffing region of described newly-generated image in 2 D code is specified the pixel filling of image correspondence position, adjust according to this fill area correspondence position Quick Response Code color attribute color value to the image pixel inserting data stuffing region, obtain inserting the Quick Response Code of specifying image in data stuffing district.Picture covered compared with the method for appointed area with just utilizing error correcting code in prior art, the method with image completion Quick Response Code that the embodiment of the present invention provides, take full advantage of Quick Response Code fill area, image is embedded in Quick Response Code, image in 2 D code is made both to have had the function of coding transmission of information, there is again the function of vision transmission of information, change the defect that existing Quick Response Code visual effect is not good to a certain extent, improve the utilization factor of Quick Response Code, make Quick Response Code can better be used for brand promotion and products propaganda.
