[0002] With the widespread adoption of devices equipped with cameras, the use of QR codes has become increasingly common. QR codes typically consist of a matrix composed of a series of black and white square units arranged according to certain rules. Because traditional QR codes are primarily composed of black and white square units, from a user's perspective, the content is monotonous and the visual experience is poor.

[0003] There are some existing methods for beautifying QR codes, but most of these methods rely on neural network models to learn and enhance the QR code. This requires developers to train the neural network, thus necessitating a certain level of neural network knowledge and increasing the difficulty of implementation.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0050] The embodiments of the present invention disclosed herein are described in more detail below with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the accompanying drawings and embodiments disclosed herein are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

[0052] The first aspect of this invention discloses a method for beautifying QR codes, comprising:

[0053] S100. Construct a QR code beautification material library, which includes at least one image package with beautification style. Each image package includes a set of image materials for matching different styles of QR code unit block combinations. Specifically, traditional QR codes are generally composed of several black unit blocks and several white unit blocks. The image materials in the image package of this invention are used for replacing one or more black unit blocks in combination. See Appendix. Figure 2 The QR code on the left side of the image uses a single black unit block, which is easily understood as having a size of 1. Two black unit blocks can form a 1x2 grid or a 2x1 grid. Three black unit blocks can be arranged in a 2x2 grid, with any three blocks randomly selected to fill the grid. Therefore, there are multiple ways to combine three black unit blocks, and similarly, there are other combinations of various numbers of black unit blocks. The image materials in this invention are designed based on these combinations of black unit blocks. The image package includes at least two image materials corresponding to different combinations of black unit blocks. To ensure that the beautified QR code is more harmonious, the design style of each image material in an image package is consistent.

[0054] S200. Obtain the initial QR code to be beautified. The initial QR code consists of a number of black unit blocks and a number of white unit blocks. In this step of the present invention, the traditional style QR code to be beautified is obtained. The traditional style QR code has a positioning graphic area (i.e., a combination area of ​​brown unit blocks in the shape of a square) and a non-positioning graphic area (i.e., the area other than the combination of black unit blocks in the shape of a square).

[0055] S300. Based on the target beautification style selected by the user, obtain the target image package corresponding to the target beautification style from the QR code beautification material library; In this invention, the QR code beautification material library can provide image packages with multiple beautification styles for the user to choose from. For a QR code to be beautified, the user can select a target image package of a target beautification style to beautify the QR code.

[0056] S400. Match and replace the constitutive area of ​​the black unit block in the initial QR code for each image material in the target image package; in this step, the constitutive area of ​​the black unit block in the initial QR code is replaced with various image materials in the target image package. The various image materials include image materials that match 1 black unit block, image materials that match a combination of 2 black unit blocks, image materials that match a combination of 3 black unit blocks, and so on.

[0057] In an optional embodiment of step S400 of the first aspect of the present invention, the step of matching and replacing the constitutive region of the black unit block in the initial QR code for each image material in the target image package includes:

[0058] The first image material and the second image material are obtained from the target image package to replace the positioning graphic in the initial QR code. In this step, the positioning graphic in the initial QR code generally includes a central positioning area composed of several black unit blocks in the middle and a square-shaped outer peripheral area composed of several black unit blocks around the central positioning area. The first image material can be the image material used to replace the central positioning area, and the second image material can be the image material used to replace the square-shaped outer peripheral area.

[0059] The first sub-region of the positioning graphic is determined from the constitutive region of the black unit block of the initial QR code by shape matching; in this step, the first sub-region of the positioning graphic is found from the initial QR code by using a back-shaped matching method.

[0060] The black unit blocks in the first sub-region are replaced using the first image material and the second image material; in this step, the black unit blocks in the square-shaped region are replaced using the first image material and the second image material.

[0061] In the second sub-region outside the first sub-region of the constitutive region of the initial QR code's black unit blocks, continuous adjacent black unit block identification is performed to obtain several third sub-regions with different styles from the second sub-region. In this step, for the second sub-region outside the first sub-region, a target black unit block is selected as the starting point, and then the surrounding black unit block is traversed to see if there are other black unit blocks. If there are, the surrounding black unit blocks are combined with the target black unit block. Then, for each surrounding black unit block in the combination, the surrounding black unit blocks are traversed to see if there are other black unit blocks. The adjacent black unit blocks of each surrounding black unit block are then found. The above operation is performed on each outermost black unit block until each outermost black unit block has no outermost adjacent black unit blocks. This is considered to have obtained a third sub-region composed of black unit blocks. Then, another black unit block is selected outside this third sub-region, and the search and combination of black unit blocks to obtain the third sub-region is repeated. This will result in several third sub-regions with different styles.

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

[0063] In an optional embodiment of the first aspect of the present invention, in order to make the matching process more orderly, the present invention uses each image material in the image package as a basis for matching. That is, firstly, one image material is taken out from the image package, and it is determined whether there is a target third sub-region that matches the image material in several third sub-regions. Furthermore, in order to make the matching process more orderly, the order in which the image materials in the image package are taken out is also limited. That is, the image material with the largest size (corresponding to the one with the most black unit blocks) is taken out first for matching. In this way, after the matching and replacement, the number of image materials used will be better, and the style of the beautified QR code will be more coordinated.

[0064] Specifically, in terms of concrete steps, for each of the third sub-regions, obtaining the corresponding third image material from the target image package based on the shape of the third sub-region, and replacing the third sub-region with the third image material includes: sorting several third sub-regions of different styles from largest to smallest based on the number of black unit blocks contained in the third sub-region; and matching the third image material sequentially for several third sub-regions of different styles according to the sorting from largest to smallest.

[0065] In an optional embodiment of the first aspect of the present invention, since each of the third sub-regions contains varying numbers of black unit blocks, matching is relatively simple for third sub-regions with fewer black unit blocks. However, for third sub-regions with more black unit blocks, the more combination patterns there are, and the lower the probability of successfully matching image materials. Therefore, it is necessary to appropriately segment the third sub-regions with more black unit blocks, that is, to piece together the third sub-regions with multiple image materials. In terms of specific process steps, the matching of third image materials for several third sub-regions with different patterns in descending order includes: for each third sub-region, determining 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, then matching a single third image material is performed on the third sub-region; if the number of black unit blocks contained in the third sub-region is greater than the preset threshold, then combining and matching multiple third image materials is performed on the third sub-region.

[0066] In an optional embodiment of the first aspect of the present invention, the combination of three black unit blocks can be arranged in patterns including one on top and two on the bottom (including one on top and one on the right) and two on top and one on the bottom (similarly including one on the bottom and one on the right), or the three black unit blocks can be arranged in a straight line. When matching a single third image material, to improve matching efficiency, suitable image materials can be initially screened based on the number of black unit blocks in the length direction and the width direction of the third sub-region. Then, a second screening is performed by comparing the distribution of each black unit block in the length direction, and a third screening is performed by comparing the distribution of each black unit block in the width direction, ultimately obtaining the required image materials. This leads to specific process steps. The above describes the process of matching a single third image material in the third sub-region if the number of black unit blocks contained in the third sub-region is less than or equal to a preset threshold. This process includes: obtaining the number of first unit blocks in the length direction and the number of second unit blocks in the width direction of the third sub-region; obtaining a preliminary matching set of third image materials in the target image package based on the number of first unit blocks and the number of second unit blocks; obtaining a first arrangement pattern of the black unit blocks in the length direction of the third sub-region, and performing a first screening of the third image material set based on the first arrangement pattern to obtain a preliminary screening set of third image materials; obtaining a second arrangement pattern of the black unit blocks in the width direction of the third sub-region, and performing a second screening of the preliminary screening set of third image materials based on the second arrangement pattern to obtain the target third image material.

[0067] In an optional embodiment of the first aspect of the present invention, when performing combination matching of multiple image materials for 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 harmonious, it is necessary to reduce the types of image materials in the replacement process, that is, to select the third sub-region using the fewest image materials. Therefore, it is necessary to filter the combination matching of the obtained multiple image materials. In terms of specific process steps, if the number of black unit blocks contained in the third sub-region is greater than a preset threshold, then performing combination matching of multiple third image materials for the third sub-region includes: if there are multiple results of the combination matching, then obtaining the number of third image materials in each combination matching; selecting the combination matching with the fewest number to replace the third sub-region.

[0068] In an optional embodiment of the first aspect of the present invention, in order to better reflect the difference between the image materials of the third sub-region and other regions, the third sub-region should have better overall integrity and the transition between the various image materials should be more reasonable. In terms of specific process steps, if the number of black unit blocks contained in the third sub-region is greater than a preset threshold, then after performing combination matching of multiple third image materials in the third sub-region, the process includes: replacing the third sub-region with multiple third image materials and performing color smoothing transition processing at the junction of the multiple third image materials.

[0069] S500: After the constitutive areas of the black unit blocks in the initial QR code are replaced by the matched image materials, an enhanced QR code is obtained. In this invention, after the constitutive areas of the black unit blocks in the initial QR code are all replaced by suitable image materials, an enhanced QR code can be obtained.

[0070] In short, the main process of the QR code beautification method of this invention can be... Figure 3 As shown, the core idea 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 standard 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 image of the unit 1x1. Other types such as 1x3, 2x2, etc. are optional.

[0072] Step 2: Calculate the position of the image material; The image position is calculated by matching the QR code array (i.e., the combination of black unit blocks) from the largest to the smallest image. If the match is successful, the position in the original array is marked as a match, and the next round of traversal will not participate. Finally, the position array of the image 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. Finally, an aesthetically pleasing QR code based on the image material can be generated.
