detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

In order to make the color information in the color two-dimensional image code contain the effective information, and not only to bring a visual impact to the human, the embodiment of the present application provides a method and a device for generating and reading the color identification type color two-dimensional image code.

A method for generating a color-coded color two-dimensional image code provided by an embodiment of the present application is first introduced.

As shown in FIG. 1 , a method for generating a color-coded color two-dimensional image code may include:

S101. Acquire original information to be encoded, and convert it into binary bit stream data.

The original information to be encoded may be any information that needs to be stored in the color two-dimensional image code to be generated, and may be, for example, a manufacturer of the product, a production date, a web address link of the webpage, and the like. The conversion of the original information to be encoded into the binary bit stream data can be implemented by the prior art, and is not specifically limited herein. For example, if the original information to be encoded is Chinese character type information, it can be converted into binary bit stream data by using the national standard method; if the original information to be encoded is English letter type information, it can be ASCII coded. Converted to binary bitstream data.

S102. Group the binary bit stream data, so that the number of groups obtained by the group is set to be The number of elements entering the matrix is the same;

Each of the sets of data includes binary bit stream data of a predetermined number of bits, the predetermined number of bits being determined based on a predetermined color model, which may be an RGB model, and correspondingly, the predetermined number of bits is three bits. The number of rows and columns to be placed in the matrix may be determined according to the type of the color two-dimensional image code actually generated. For example, if a color two-dimensional image code of the D9ing code type is to be generated, the matrix to be placed is one. The empty matrix of 448 rows and 448 columns is of course not limited to this.

Specifically, the method for grouping the binary bit stream data may generally be in one of two ways:

The first way is: grouping the binary bit stream data in groups of three according to a predetermined traversal order, and then determining whether the number of groups obtained by the group is the same as the number of elements to be placed in the matrix, and if not, continuing to follow The predetermined traversal sequence groups the binary bit stream data in groups of three until the number of groups is satisfied, wherein the predetermined traversal order is from left to right or from right to left.

It should be noted that, in order to store all the original information to be encoded into the color two-dimensional image code to be generated, the predetermined to-be-placed matrix is the binary bit stream data that can convert all the original information to be encoded. Into, that is, the number of groups obtained by the above grouping is generally not greater than the number of elements to be placed in the matrix.

When it is judged that the number of groups obtained by the packet is smaller than the number of elements to be placed in the matrix, the binary bit stream data is further grouped in groups of three bits in accordance with a predetermined traversal order until the number of groups is satisfied. For example, the binary bit stream data converted by the original information to be encoded is 10010001011, and the binary bit stream data is grouped in groups of three bits according to a predetermined left-to-right traversal order to obtain three sets of data. They are: (1,0,0), (1,0,0), (0,1,0), and the remaining two binary bit stream data 1 and 1. If the number of elements to be placed in the matrix is four, since the number of groups respectively obtained is three, which is smaller than the number of elements to be placed in the matrix, the binary bit stream data is further grouped according to the traversal order from left to right, and the remaining The two binary bit stream data 1, 1 and the first bit binary bit stream data 1 are grouped into one group to obtain a fourth group of data (1, 1, 1), and the number of groups obtained by grouping at this time is to be placed The number of elements in the matrix is the same and the grouping is stopped. It is of course also possible to group the binary bit stream data in a traversal sequence from right to left. The specific process is similar to the above process of grouping the binary bit stream data in a traversal order from left to right. This will not be described in detail.

The second way is: grouping the binary bit stream data in groups of three according to a predetermined traversal order; determining whether the number of groups obtained by the group is the same as the number of elements to be placed in the matrix, and if not, the number is 0. As the supplementary binary bit stream data of the binary bit stream data, the binary bit stream data remaining in the current packet is continued to be grouped until the number of groups is satisfied, wherein the predetermined traversal order is: left to right order or The order from right to left.

As described above, the number of groups obtained by grouping is generally not greater than the number of elements to be placed in the matrix. When it is judged that the number of groups obtained by the group is smaller than the number of elements to be placed in the matrix, the number 0 is used as the binary bit stream. The data complements the binary bit stream data and continues to group the remaining binary bit stream data of the current packet until the number of groups is met. For example, the binary bit stream data converted from the original information to be encoded is 10010001011, and the binary bit stream data is grouped in groups of three bits according to the traversal order from left to right, and three sets of data are obtained, respectively. : (1,0,0), (1,0,0), (0,1,0), the remaining two binary bit stream data 1 and 1. If the number of elements to be placed in the matrix is four, since the number of groups obtained by the group is three, which is smaller than the number of elements to be placed in the matrix, the number 0 is used as supplementary binary bit stream data of the binary bit stream data, and continues to The binary bit stream data remaining in the current packet is grouped to obtain a fourth group of data (1, 1, 0). At this time, the number of groups obtained by the group is the same as the number of elements to be placed in the matrix, and the packet is stopped. It is of course also possible to group the binary bit stream data in a traversal sequence from right to left. The specific process is similar to the above process of grouping the binary bit stream data in a traversal order from left to right, and no further details are performed here. Description.

S103. The set of data is placed into the to-be-placed matrix according to a preset rule to obtain an initial data matrix.

Specifically, each group of data may be sequentially placed into the to-be-placed matrix according to the Z-shaped direction, so that each element to be placed in the matrix corresponds to a set of data, and an initial data matrix is obtained. For example, grouping binary bitstream data yields four sets of data, namely: (1,0,0), (1,0,0), (0,1,0), and (1,1,0), The matrix to be placed is a second-order empty matrix, and the number of elements is four. According to the z-shaped trend, the first set of data (1, 0, 0) is sequentially placed into the first row and the first column of the matrix. Two sets of data (1, 0, 0) are placed in the first column of the second row of the matrix, and the third set of data (0, 1, 0) is placed in the first row and the second column of the matrix, and the fourth set of data is 1,1,0) placed in the second row and second column of the matrix to get the initial data matrix

It should be noted that the preset rule of the Z-shaped direction given in the embodiment of the present application is only an example, and should not be construed as limiting the embodiment of the present application. It can be understood that, in practical applications, the preset rule For example, other rules may be preset according to actual needs. For example, each group of data may be sequentially placed in each row of the matrix to be placed, and no specific limitation or description is provided herein.

S104. Expand each element in the initial data matrix by a predetermined multiple to obtain a first pixel matrix.

The predetermined multiple is determined based on the predetermined color model, and the predetermined color model is generally an RGB model. Correspondingly, the predetermined multiple is 255 times the maximum gray level, and each element in the initial data matrix is expanded by 255 times, that is, Obtaining the first pixel matrix is of course not limited thereto. For example, the above initial data matrix

Enlarge 255 times to get the corresponding first pixel matrix

S105. Determine, according to a preset correspondence between elements and colors, a color corresponding to an element in the first pixel matrix.

Specifically, the preset correspondence between elements and colors can be as follows:

Serial number	element	colour
1	(0,0,0)	black
2	(0,0,255)	blue

3	(0,255,0)	green
4	(0,255,255)	cyan
5	(255,0,0)	red
6	(255,0,255)	Magenta
7	(255,255,0)	yellow
8	(255,255,255)	white

Since the resolution of the color of the device lens or the like may be different in practical applications, the corresponding relationship between the element and the color may be modified according to actual needs, and is not limited thereto.

S106. Fill the determined color into the data storage area of the color two-dimensional image code to be generated, and fill the feature information set in advance for the original information to be encoded into the current color two-dimensional image code. In the feature information area, the generation of the color two-dimensional image code is completed.

It can be understood that the number of pixels in the data storage area of the color two-dimensional image code to be generated is the same as the number of elements in the first pixel matrix, and the number of pixels in each row and each row in the first pixel matrix. The number of elements is the same, the number of pixels in each column is the same as the number of elements in each column in the first pixel matrix, and the pixels of the data storage area of the color two-dimensional image to be generated and the elements in the first pixel matrix There is a one-to-one correspondence. After determining the color corresponding to the element, the color corresponding to the pixel of each position in the data storage area of the color two-dimensional image code to be generated is determined, for example, the first pixel matrix

The color corresponding to the pixel at the four positions of the data storage area of the corresponding color two-dimensional image code to be generated is

These colors are filled in the data storage area of the color two-dimensional image code to be generated according to the corresponding positional relationship, that is, the filling of the data storage area of the color two-dimensional image code to be generated is completed.

Further, after the data storage area of the color two-dimensional image code to be generated is filled, the feature information set in advance for the original information to be encoded is filled into the feature information area of the current color two-dimensional image code to complete the color. The generation of two-dimensional code.

It should be noted that the feature information set in advance for the original information to be encoded may include format information and version information, and the format information and the version information may be determined according to the type of the color two-dimensional image code to be generated, and the foregoing feature is The manner in which the feature information in the information area is filled in the feature information area of the current color two-dimensional image code may be used in the prior art, and is not specifically limited herein.

For example, if the color two-dimensional image code to be generated is a D9ing code type, the format information is generated according to the number of rows, the number of columns, and the error correction level of the color two-dimensional image code to be generated, and the existing D9ing code is used. The feature information filling mode fills the format information and the preset version information into the feature information area of the current color two-dimensional image code. If the color two-dimensional image code to be generated is a QR code type, the format information in the set feature information indicates an error correction level, which can be divided into four levels of L, M, Q, and H; The version information is the specification of the color two-dimensional image code to be generated of the QR code type, and one of the 40 specifications of the existing QR code can be used, and the feature information filling method of the existing QR code is adopted. The format information and the version information may be filled in the feature information area of the current color two-dimensional image code.

It should be further noted that, after the feature information in the feature information area is filled in the feature information area of the current color two-dimensional code, the method may further include:

Masking the feature information area.

The specific mask processing may adopt one of the existing mask processing according to actual needs, generally performing mask processing on the format information region in the feature information region, so that the generated color two-dimensional image code is more beautiful. At the same time, the confidentiality of the color two-dimensional image code is increased. Further, mask processing may be performed on the data storage area to increase the aesthetics of the color two-dimensional image code, so that the confidentiality is better.

It can be seen that, in the method for generating a color identification type color two-dimensional image code provided by the present scheme, the original information to be encoded is first obtained and converted into binary bit stream data; the binary bit stream data is grouped, so that The number of groups obtained by grouping is the same as the number of elements to be placed in the matrix, and then each set of data is placed into the matrix to be placed according to a preset rule to obtain an initial data moment. Array; further expanding each element in the initial data matrix by a predetermined multiple to obtain a first pixel matrix, determining a color corresponding to the element in the first pixel matrix according to a preset correspondence relationship between the element and the color, Finally, the determined color is filled into the data storage area of the color two-dimensional image code to be generated, and the feature information set in advance for the original information to be encoded is filled into the current color two-dimensional image code. In the feature information area, the generation of the color two-dimensional map code is completed. The color information in the color two-dimensional code generated by the generation method contains valid original information, not just a visual impact.

For example, one element in the second pixel matrix is (2, 0, 250), and the error correction processing thereof is specifically: performing Euclidean distance calculation separately from the preset eight elements according to the above formula. Obtaining r ₁ to r ₈ are: 250, 6, 357, 255, 356, 253, 438, and 439. It can be clearly seen that the value of r ₂ is the smallest, and the element is replaced with an element (0, 0, 255).

After the error correction processing is completed, each element in the second pixel matrix is reduced by a predetermined multiple. For example, the above element (0, 0, 255) is reduced by 255 times to obtain an element (0, 0, 1), and the second pixel is obtained. The restored data matrix is obtained by reducing each element in the matrix by a predetermined multiple.

If so, the supplemental binary bit stream data 0 is removed from the original binary bit stream data to obtain the binary bit stream data.

For example, the data set is (1,0,0), (1,0,0), (0,1,0), and (1,1,0), according to a predetermined left-to-right traversal order. Reverting the four data sets to the initial binary bit stream data 100100010110; determining that, when generating the color two-dimensional picture code, there is a supplementary binary bit stream data in which data 0 is used as the binary bit stream data in the grouping process, and continues to Current The step of grouping the remaining binary bit stream data is performed, and the supplemental binary bit stream data 0 is removed from the initial binary bit stream data 100100010110 to obtain the binary bit stream data 10010001011.
