[0002] With the popularity of terminals with cameras, the application of QR codes has become more and more popular.

[0052] The first aspect of the present invention discloses a method for beautifying a two-dimensional code, comprising:

[0053] S100, constructing a two-dimensional code beautification material library, wherein the two-dimensional code beautification material library includes at least one beautification style picture package, each of which includes a set of picture materials for matching different styles of two-dimensional code unit block combinations; specifically, a traditional two-dimensional code is generally composed of a plurality of black unit blocks and a plurality of white unit blocks, and the picture materials in the picture package of the present invention are used for combining and replacing one or more black unit blocks, as shown in the attached figure. Figure 2 In the QR code on the left side, in the present invention, 1 black unit block is easy to understand, and the specification is 1; 2 black unit blocks can be combined into a combination of length and width of 1*2, or a length and width of 2*1; 3 black unit blocks can be combined into a 2*2 field-shaped square, and any three of them can be filled with 3 black unit blocks. Therefore, there are many combinations of 3 black unit blocks, and so on, there are other combinations of various numbers of black unit blocks. The picture material of the present invention is designed based on the combination of black unit blocks, and the picture package includes at least two picture materials corresponding to different combinations of black unit blocks. In order to ensure that the beautified QR code is more coordinated, the design style of each picture material in a picture package is consistent.

[0054] S200, obtaining an initial two-dimensional code to be beautified, wherein the initial two-dimensional code is composed of a plurality of black unit blocks and a plurality of white unit blocks; in this step of the present invention, a traditional style two-dimensional code to be beautified is obtained, wherein the traditional style two-dimensional code has a positioning graphic area (i.e., a combination area of ​​brown unit blocks in the shape of a Chinese character "U") and a non-positioning graphic area (i.e., an area other than the combination of black unit blocks in the shape of a Chinese character "U").

[0055] S300. Based on the target beautification style selected by the user, a target picture package corresponding to the target beautification style is obtained from the QR code beautification material library; in the present invention, the QR code beautification material library can provide picture packages with multiple beautification styles for users to choose from. For a QR code to be beautified, the user can select a target picture package with a target beautification style to beautify the QR code.

[0056] S400, match and replace the area constituting the black unit blocks in the initial two-dimensional code with each picture material in the target picture package; in this step, the area constituting the black unit blocks in the initial two-dimensional code is replaced with various picture materials in the target picture package, and the various picture materials include picture materials matching 1 black unit block, materials matching a combination of 2 black unit blocks, picture materials matching a combination of 3 black unit blocks, and so on.

[0057] In an optional implementation of step S400 of the first aspect of the present invention, matching and replacing the area constituting the black unit blocks in the initial two-dimensional code with each of the picture materials in the target picture package includes:

[0058] The first picture material and the second picture material for replacing the positioning pattern in the initial two-dimensional code are obtained from the target picture package; in this step, the positioning pattern in the initial two-dimensional code generally includes a central positioning area composed of a plurality of black unit blocks in the middle and a square-shaped peripheral area surrounding the central positioning area and composed of a plurality of black unit blocks, the first picture material can be a picture material for replacing the central positioning area, and the second picture material can be a picture material for replacing the square-shaped peripheral area;

[0059] The first sub-region of the positioning pattern is determined from the area constituted by the black unit blocks of the initial two-dimensional code by shape matching; in this step, the first sub-region of the positioning pattern is found from the initial two-dimensional code by U-shaped matching.

[0060] The black unit blocks in the first sub-area are replaced by the first picture material and the second picture material; in this step, the black unit blocks in the U-shaped area are replaced by the first picture material and the second picture material.

[0061] The second sub-region outside the first sub-region in the area constituting the black unit blocks of the initial two-dimensional code is continuously identified as adjacent to the black unit blocks, and a number of third sub-regions with different styles are obtained from the second sub-region; in this step, for the second sub-region outside the first sub-region, first select a target black unit block as the starting point, and then traverse whether there are other black unit blocks around the target black unit block, if so, combine the surrounding black unit blocks with the target black unit block, and then traverse whether there are other black unit blocks around each surrounding black unit block in the combination, and find the adjacent black unit blocks of each surrounding black unit block, and perform the above operation on each circle of black unit blocks on the periphery until each black unit block in the outermost circle has no adjacent black unit blocks in the outer circle, so that a third sub-region is obtained, and then another black unit block is selected outside the third sub-region, and the search and combination are repeated to obtain the black unit blocks of the third sub-region, so that a number of third sub-regions with different styles will be obtained.

[0062] For each of the third sub-regions, a third picture material corresponding to the third sub-region is obtained from the target picture package based on the shape of the third sub-region, and the third picture material replaces the third sub-region. In the present invention, each of the third sub-regions has a corresponding target shape (i.e., how many black unit blocks are composed of the third sub-region, and what is the arrangement pattern of the black unit blocks), and this step is to match the picture material based on the pattern of the black unit blocks in the third sub-region.

[0063] In an optional implementation of the first aspect of the present invention, in order to make the matching process more orderly, the present invention performs matching based on each picture material in the picture package, that is, first take out a picture material from the picture package, and determine whether there is a target third sub-region matching the picture material among the plurality of third sub-regions. Furthermore, in order to make the matching process more orderly, the order in which the picture materials in the picture package are taken out is also limited, that is, the picture with the largest size (corresponding to the most black unit blocks) is taken out first for matching. In this way, after the matching and replacement, the number of picture materials used will be better, and the style of the beautified QR code will be more coordinated.

[0064] Specifically, the specific steps are as follows: for each of the third sub-regions, the third picture material corresponding to the third sub-region is obtained from the target picture package based on the shape of the third sub-region, and the third picture material is used to replace the third sub-region, including: sorting the third sub-regions of several different styles from large to small based on the number of black unit blocks contained in the third sub-regions; and for the third sub-regions of several different styles, matching the third picture materials in order from large to small.

[0065] In an optional implementation of the first aspect of the present invention, since each of the third sub-regions contains black unit blocks of varying numbers, it is relatively simple to match the third sub-region with fewer black unit blocks, but for the third sub-region with more black unit blocks, the more black unit blocks there are, the more combination styles there are, and the probability of successfully matching the image material is smaller, so it is also necessary to appropriately divide the third sub-region with more black unit blocks, that is, to piece together the third sub-region with multiple image materials, which, converted to specific process steps, is to match the third sub-regions of several different styles in order from large to small, including: for each of the third sub-regions, determine whether the number of black unit blocks contained in the third sub-region is greater than a preset threshold; if the number of black unit blocks contained in the third sub-region is less than or equal to the preset threshold, match a single third image material for the third sub-region; if the number of black unit blocks contained in the third sub-region is greater than the preset threshold, match a combination of multiple third image materials for the third sub-region.

[0066] In an optional implementation of the first aspect of the present invention, taking the combination of three black unit blocks as an example, the styles that can be combined include one on top and two on the bottom (including the upper one on the left and the upper one on the right) and two on top and one on the bottom (similarly including the lower one on the right and the lower one on the right), and the three black unit blocks can also be arranged in a straight line; when matching a single third image material, in order to improve the matching efficiency, based on the number of black unit blocks in the length direction and the number of black unit blocks in the width direction of the third sub-area, a preliminary screening of suitable image materials can be performed, and then a further comparison is made on how the various black unit blocks are distributed in the length direction for a second screening, and after the second screening, a comparison is made on how the various black unit blocks are distributed in the width direction for a third screening, and finally the required image material is obtained, and converted to specific process steps. That is, if the number of the black unit blocks contained in the third sub-region is less than or equal to a preset threshold, then matching the third sub-region with a single third picture material includes: obtaining the first number of unit blocks in the length direction and the second number of unit blocks in the width direction of the third sub-region respectively; obtaining a preliminary matching third picture material set in the target picture package based on the first number of unit blocks and the second number of unit blocks; obtaining a first arrangement pattern of the black unit blocks in the length direction of the third sub-region, and screening the third picture material set once based on the first arrangement pattern to obtain a preliminary screening third picture material set; obtaining a second arrangement pattern of the black unit blocks in the width direction of the third sub-region, and screening the preliminary screening third picture material set twice based on the second arrangement pattern to obtain the target third picture material.

[0067] In an optional implementation of the first aspect of the present invention, when performing combination matching on the third sub-region, there are many ways to combine the multiple image materials corresponding to the third sub-region. In order to make the beautified QR code more coordinated, it is necessary to reduce the types of image materials in the replacement process, that is, to select the least image materials to piece together the third sub-region. Therefore, it is necessary to screen the combination matching of the obtained multiple image materials and convert them to specific process steps, that is, if the number of black unit blocks contained in the third sub-region is greater than a preset threshold, then performing combination matching on the third sub-region includes: if there are multiple results of the combination matching, obtaining the number of the third image materials in each combination matching; selecting the combination matching with the least number to replace the third sub-region.

[0068] In an optional implementation of the first aspect of the present invention, in order to better reflect that the third sub-region is different from the picture materials in other regions, the third sub-region has better integrity, and the transition between the various picture materials is also required to be more reasonable. Translated to the specific process steps, that is, if the number of black unit blocks contained in the third sub-region is greater than the preset threshold, then the combination matching of multiple third picture materials in the third sub-region includes: replacing the multiple third picture materials in the third sub-region, and performing color smoothing transition processing on the connection between the multiple third picture materials.

[0069] S500: When the regions of the black unit blocks in the initial two-dimensional code are replaced by the matched picture materials, a beautified two-dimensional code is obtained. In the present invention, when the regions of the black unit blocks in the initial two-dimensional code are replaced by the appropriate picture materials, a beautified two-dimensional code can be obtained.

[0070] In short, the main process of the beautification method of the two-dimensional code of the present invention can be Figure 3 As shown, the core ideas can be summarized as follows:

[0071] Step 1: Material preparation, QR code data: Generate a two-dimensional array of QR codes according to the general standards of QR codes; Image material: The essence of a QR code is a two-dimensional array containing 0 and 1. You need to prepare at least one material with a unit of 1x1. Other types such as 1x3, 2x2, etc. are optional.

[0072] Step 2: Calculate the position of the image material; Calculate the image position, match the image material with the array of QR codes (i.e., the combination of black unit blocks) from large to small. If the match is successful, the original array position is marked as a hit, and the next round of traversal will not be involved, and finally the position array where the image needs to be drawn is obtained;

[0073] Step 3: Draw the QR code; determine the replacement position of the image material, and replace the black unit blocks of the QR code with the image material, and finally generate a beautified QR code based on the image material.
