[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention. Similarly, the following examples are only partial embodiments of the present invention rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Traditional two-dimensional codes are mainly divided into two categories: row-type two-dimensional barcodes and matrix-type two-dimensional barcodes. Row-type two-dimensional codes are based on one-dimensional barcodes. They inherit some characteristics of one-dimensional codes in terms of coding design, verification principle, and reading method. Common row-type two-dimensional codes include Code 16K, PDF417, Code49, etc.; matrix-type two-dimensional codes use a certain set of graphics to distribute black and white graphics on a plane (two-dimensional direction) according to a certain rule to record data symbol information. In terms of coding, they cleverly use the 0 and 1-based concepts that constitute the internal logic basis of computers, and use several sets of shapes corresponding to binary to represent text numerical information. Common matrix-type two-dimensional barcodes mainly include QR Code, Data Matrix, Maxi Code, Code one, etc.

[0031] Compared with one-dimensional code, two-dimensional code has the following advantages: high coding density and large information capacity; multiple coding objects, which can represent text and images; strong fault tolerance and error correction function; high decoding reliability; encryption and good anti-counterfeiting performance. With the widespread application of two-dimensional code, people have further requirements for barcode information storage and information processing. Solutions to increase barcode size or increase barcode density have their limitations: increasing barcode size requires the barcode carrier to provide a larger printing area; increasing barcode density requires higher requirements for printing equipment and reading equipment in terms of accuracy, and will reduce the barcode's anti-interference ability, greatly limiting the use environment of the barcode; to solve these problems, two-dimensional barcodes have been expanded and a new barcode, three-dimensional code, has been proposed. Three-dimensional code adds a dimension to carry information on the basis of two-dimensional code to increase the information capacity of the barcode. The most common three-dimensional code uses color as the third dimension of information carrier. It applies color coding on the basis of traditional barcodes and represents data information through different color combinations. It has the code structure of a two-dimensional barcode, but its information density is much greater than that of a two-dimensional barcode of the same size. However, color is used as the information carrier of the third dimension in the three-dimensional code, and the information carrier form is single. The data information is represented by the combined color, which makes the data capacity limited, and the boundaries of the combined colors may be unclear, resulting in data information errors and poor information security and reliability, thus affecting the scope of use of the three-dimensional code.

[0032] Therefore, a method for generating a digital three-dimensional code is provided, which can effectively increase the storage capacity of data storage, thereby increasing the speed of data processing, and reducing misrecognition caused by color errors, thereby improving information reliability.

[0033] See also Figure 1 , Figure 1 is a flow chart of an embodiment of a method for generating a digital three-dimensional code in the present application; it should be noted that if there is a substantial result, the method of the present application is not based on Figure 1 The process sequence shown is limited.

[0034] like Figure 1 As shown, the method for generating a digital three-dimensional code may include the following steps.

[0035] S10, obtaining at least two initial two-dimensional codes with the same encoding method, and assigning a value to each block in each initial two-dimensional code to determine a first value of each block, wherein each initial two-dimensional code stores original information.

[0036] Among them, the initial two-dimensional code is the currently commonly used two-dimensional code, the encoding method refers to the encoding method of forming the two-dimensional code, such as the encoding methods corresponding to the row-type two-dimensional barcode and the matrix two-dimensional barcode respectively. The same encoding method means that the type of two-dimensional code formed is the same, such as the matrix two-dimensional code. The number of two-dimensional codes formed by the same encoding method can be two or more, and the number of rows and columns of each two-dimensional code remains consistent; the block refers to the block corresponding to each pixel distribution in the two-dimensional code, such as black blocks and white blocks; the first value is a constant, and the original information is the information stored in the initial two-dimensional code.

[0037] Specifically, at least two currently commonly used initial QR codes corresponding to the same encoding method are obtained, each QR code stores corresponding original information, and based on the distribution of black blocks and white blocks in the initial QR code, each block in each QR code is assigned a value, so that each block of each QR code has a corresponding first numerical value.

[0038] In some embodiments, different values ​​may be assigned to the black blocks and the white blocks to distinguish the black blocks from the white blocks. For example, the black blocks are assigned a value of 1 and the white blocks are assigned a value of 0.

[0039] S20, concatenating first values ​​of the same block of at least two initial two-dimensional codes, and converting the concatenated result into a second value of the target base.

[0040] Among them, splicing refers to splicing the first values ​​of the same block together in order. For example, three initial QR codes correspond to three first values ​​in the same block, and the splicing result is a three-digit value of the arrangement of the same block; the target system refers to another system different from the system corresponding to the first value, and the second value is the three-digit number converted to the number corresponding to the target system.

[0041] Specifically, after obtaining the first value of each block of each initial QR code, for the same block, the first values ​​of the same block of at least two initial QR codes are spliced ​​together to obtain a value of at least two digits. As the splicing result, the target base is determined based on the value of the at least two digits, and then the value of the at least two digits is converted into a second value corresponding to the target base.

[0042] In some embodiments, the first value is a single digit, and the second value is also a single digit.

[0043] S30. Assign the second numerical value to the two-dimensional code template to form a digital three-dimensional code, wherein original information of at least two initial two-dimensional codes is stored in the digital three-dimensional code.

[0044] The QR code template is a blank template corresponding to the same encoding method as the initial QR code.

[0045] Specifically, after obtaining the second value of each block, a blank QR code template is used to assign the corresponding second value to each block in the QR code template to form a digital three-dimensional code. Because the second value corresponding to each block in the digital three-dimensional code is converted from at least two first values, the second value of each block contains the original information corresponding to the same block in the initial QR code. Therefore, the digital three-dimensional code contains the original information corresponding to at least two initial QR codes.

[0046] In this embodiment, for the initial two-dimensional code with the same encoding method, each block in the initial two-dimensional code is converted into a numerical value according to the element distribution to obtain the first numerical value corresponding to each block, and then the first numerical values ​​are spliced ​​and converted, and the second numerical value of the target base obtained by the conversion is assigned to a blank two-dimensional code template to obtain a digital three-dimensional code, which can effectively increase the storage capacity of data storage, and the original information of multiple initial two-dimensional codes can be stored in the corresponding digital three-dimensional code, which can increase the speed of data processing. For example, there is no need to scan multiple initial two-dimensional codes, which effectively improves the reading speed, and there is no color dimension, which reduces the misrecognition caused by color errors and improves information reliability.

[0047] In some embodiments, step S10 obtains at least two initial two-dimensional codes with the same encoding method, and assigns a value to each block in each initial two-dimensional code to determine the first value of each block, which may include the following operations.

[0048] First, the pixel distribution of each block in the encoding area of ​​each initial two-dimensional code is obtained.

[0049] Among them, each initial two-dimensional code includes at least a coding area, which is the area for storing original information; pixel distribution refers to the distribution of black blocks and white blocks, that is, the distribution of dot pixels and blank pixels.

[0050] Specifically, for each initial two-dimensional code, since the original information is stored, a pixel distribution corresponding to the original information is formed in the coding area of ​​the initial two-dimensional code, and then the pixel distribution of each block in the coding area of ​​each initial two-dimensional code can be obtained.

[0051] See also Figure 2a , Figure 2b and Figure 2c , Figure 2a It is a structural diagram of an embodiment of code A in this application. Figure 2b is a schematic diagram of the structure of an embodiment of code B in this application, Figure 2c It is a structural diagram of an embodiment of C code in this application.

[0052] like Figure 2a , Figure 2b and Figure 2c As shown, QR code A, QR code B and QR code C are actual QR codes, which are represented here as block diagrams. The pixel distribution of each block in the encoding area of ​​each initial QR code is determined by the black blocks and white blocks in the actual QR code.

[0053] Then, each block is binarized using pixel distribution to determine a first value of each block in each initial two-dimensional code.

[0054] The binarization process refers to assigning a value to each block according to pixel distribution.

[0055] Specifically, after obtaining the pixel distribution of each block, the black block and white block corresponding to each block in the initial QR code can be determined, and then each block is assigned a value based on the pixel distribution. For example, the black block is assigned a value of 1 and the white block is assigned a value of 0, and the first numerical value corresponding to each block in each initial QR code is determined.

[0056] See also Figure 3a , Figure 3b and Figure 3c , Figure 3a It is a structural diagram of an embodiment of assigning a value to the A code in this application. Figure 3b is a structural diagram of an embodiment of assigning a value to a B code in this application, Figure 3c It is a structural diagram of an embodiment of assigning a value to a C code in the present application.

[0057] like Figure 3a , Figure 3b and Figure 3c As shown, a black block is assigned a value of 1, and a white block is assigned a value of 0, and a first numerical value corresponding to each block in each initial two-dimensional code is determined.

[0058] In some embodiments, after determining the first value of each block, it is also necessary to clear the pixel distribution corresponding to each block, that is, remove the background color of the black block and the white block to form a blank block, and then assign the first value to the blank block.

[0059] In this embodiment, the pixel distribution of the initial two-dimensional code is converted into the first numerical value corresponding to each block, which is convenient for the subsequent splicing and conversion of numerical values, that is, provides a basis for the subsequent.

[0060] In some embodiments, step S20 concatenates the first values ​​of the same block of at least two initial two-dimensional codes and converts the concatenation result into a second value of the target base, which may include the following steps.

[0061] First, at least two initial two-dimensional codes are superimposed, and the number information and superimposition order of the superimposed initial two-dimensional codes are obtained.

[0062] Among them, superposition refers to the superposition of multiple initial two-dimensional codes corresponding to the production of digital three-dimensional codes; the number information refers to the number of initial two-dimensional codes that need to be superimposed; and the superposition order refers to the order in which the two-dimensional codes are superimposed in sequence.

[0063] Specifically, obtain the number information of the initial QR codes that need to be superimposed, and obtain the superposition order of the superimposed initial QR codes; for example, the initial QR codes that need to be superimposed include code A, code B and code C, then the number information is 3, and the superposition order can be code A, code B, code C, or code A, code C, code B, or code B, code A, code C, or code B, code C, code A, or code C, code A, code B, or code C, code B, code A, and you can select any superposition order from them.

[0064] Secondly, the first values ​​of the same block in each initial two-dimensional code are spliced ​​using the number information and the superposition order to determine the splicing result of each block in the coding area.

[0065] The splicing refers to splicing the first values ​​of the same block according to the number information and the superposition order to form a value of the number of bits corresponding to the number information.

[0066] Specifically, after obtaining the number information and the stacking order of the initial two-dimensional code, the first value of the same block is spliced ​​in each block corresponding to the two-dimensional code, and then the splicing result of each block in the coding area is determined.

[0067] See also Figure 4 , Figure 4 It is a structural schematic diagram of an embodiment of the splicing result in this application.

[0068] like Figure 4 As shown, the number of superposition information is set to 3, and the superposition order is A code, B code, and C code. After superimposing A code, B code, and C code, each block in the coding area has a corresponding three-digit value.

[0069] Next, use the number information to determine the target base.

[0070] The target base refers to a suitable base determined based on the number information.

[0071] Specifically, the bit value corresponding to the unit-digit information in each block needs to be converted into the unit-digit value, and the base corresponding to the conversion is the target base.

[0072] Then, the splicing result of each block is converted using the target base to determine the second value of each block in the coding area, wherein the second value is a single-digit value.

[0073] The second value refers to a value obtained after converting the splicing result, and the second value is a single digit.

[0074] Specifically, after determining the target system, the splicing result corresponding to each block in the coding area is converted to the value of the target mechanism, and then the second value of each block in the coding area is determined; for example: taking the number of superimposed information as 3, and the superimposed order as A code, B code, and C code as an example, after superposition, each block in the coding area has a corresponding three-digit value, then hexadecimal can be used as the target system to convert the three-digit value into a single-digit value, that is, 000 is converted to 0, 001 is converted to 1, 010 is converted to 2, 100 is converted to 4, 101 is converted to 5, 110 is converted to 6, and 111 is converted to 7; and then the second value of the corresponding single-digit number in each block is determined.

[0075] In some embodiments, the digital three-dimensional code includes a functional area and a coding area.

[0076] The function area is used to store the number information and the superposition order, and the coding area is used to store the original information of at least two initial two-dimensional codes.

[0077] The coding region is Figure 4 The area where numerical conversion is performed, and the functional area is the area where non-numerical conversion is performed.

[0078] For details, please refer to Figure 4 In the functional area of ​​non-numeric conversion, the number information and superposition order of the initial two-dimensional code superposition can be stored; in addition, because the initial two-dimensional code itself stores the original information, and the coding area for numerical conversion still stores the corresponding original information, the coding area will store the original information of the superimposed initial two-dimensional code.

[0079] In some embodiments, step S30 uses the second numerical value to assign a value in the two-dimensional code template to form a digital three-dimensional code, which may include the following steps.

[0080] First, a plane matrix with the same encoding method as the initial two-dimensional code is obtained as a two-dimensional code template, wherein the two-dimensional code template has at least a first functional area, a second functional area and a coding area.

[0081] The plane matrix refers to a blank matrix corresponding to the same encoding method as the initial two-dimensional code.

[0082] Specifically, a corresponding blank plane matrix is ​​obtained using the same encoding method as the initial two-dimensional code and used as a two-dimensional code template. In addition, in the two-dimensional code template, the encoding area is blank, while the functional area at the boundary line position retains the format of the initial two-dimensional code.

[0083] In some embodiments, the QR code template may have a first functional area and a second functional area, for example, Figure 4 The rectangular box in the upper left corner is the first functional area. Figure 4 The rectangular box in the upper right corner is the second functional area; in some embodiments, it may also include Figure 4 The rectangular box in the lower left corner serves as the third functional area.

[0084] Secondly, the number information or the order of superimposed initial two-dimensional codes is set in the first functional area, and the order or the number information of superimposed initial two-dimensional codes is set in the second functional area.

[0085] Specifically, after obtaining a blank QR code template, the number information of the initial QR codes to be superimposed can be set in the first functional area, and the superposition order of the initial QR codes can be set in the second functional area; or the superposition order of the initial QR codes can be set in the first functional area, and the number information of the initial QR codes to be superimposed can be set in the second functional area.

[0086] Next, the second numerical value is used to assign values ​​in the corresponding blocks of the coding area to form a digital three-dimensional code.

[0087] Specifically, for each block in the coding area, a value is assigned in the block corresponding to the second value, so that each block in the coding area in the QR code template has a corresponding second value. Because the number information and superposition order of the initial QR codes are set in the first functional area and the second functional area, a digital three-dimensional code can be formed.

[0088] See also Figure 5 , Figure 5 It is a structural diagram of an embodiment of a digital three-dimensional code in this application.

[0089] like Figure 5 As shown, three initial two-dimensional codes: A code, B code and C code, the superposition order is A code, B code, C code, the initial two-dimensional code system is binary, and the numerical two-dimensional code system is hexadecimal as an example for explanation; specifically, the first functional area is assigned a value of 7, that is, 7 in hexadecimal, and the corresponding binary system is 111, each 1 represents a layer of initial two-dimensional code, and three 1s represent the superposition of three layers of initial two-dimensional codes, that is, three initial two-dimensional codes are superimposed; the second functional area is assigned a value of 1, which indicates that the superposition order is that the first layer of initial two-dimensional code is on the far right, that is, the superposition order is C code, B code, A code; if the second functional area is assigned a value of 0, it indicates that the superposition order is that the first layer of initial two-dimensional code is on the far left, that is, the superposition order is A code, B code, C code.

[0090] In some embodiments, it also includes:

[0091] The original information is split into multiple information segments, and each information segment is stored in an initial two-dimensional code to determine multiple consecutive related initial two-dimensional codes, wherein the encoding method of the multiple initial two-dimensional codes is the same.

[0092] The original information may be information with relatively large data contents, and if one initial QR code cannot store all of the information, the original information may be divided into multiple consecutively related initial QR codes.

[0093] Specifically, for original information with more data content, it can be divided according to the storage data volume of the initial two-dimensional code to obtain multiple information segments, and then each information segment is stored in a corresponding initial two-dimensional code to obtain multiple consecutive related initial two-dimensional codes.

[0094] A digital three-dimensional code is generated by using a plurality of consecutively related initial two-dimensional codes, so that the digital three-dimensional code stores original information of a plurality of information segments.

[0095] Specifically, because they are continuously related initial QR codes, in order to be able to be stored in one identification code, multiple continuously related initial QR codes are generated into corresponding digital three-dimensional codes according to the above-mentioned digital three-dimensional code generation method, so that multiple information segments of the original information are stored in the same digital three-dimensional code, which increases the storage capacity of data storage, so that subsequent identification can be performed by scanning the digital three-dimensional code to obtain all the original information without scanning the corresponding multiple initial QR codes, thereby reducing the speed of data processing.

[0096] In some embodiments, the present application also provides a digital three-dimensional code recognition method.

[0097] See also Figure 6 , Figure 6 It is a flow chart of an embodiment of a digital three-dimensional code recognition method in the present application.

[0098] like Figure 6 As shown, the digital three-dimensional code recognition method may include the following steps.

[0099] Y10. Obtain a second value of each block in the digital three-dimensional code, wherein the digital three-dimensional code stores original information of at least two original two-dimensional codes.

[0100] Among them, the digital three-dimensional code refers to a digital three-dimensional code formed by the aforementioned digital three-dimensional code generation method, which stores the original information of at least two initial two-dimensional codes.

[0101] Specifically, for the digital three-dimensional code, the value of each block in the digital three-dimensional code is extracted to determine the second value corresponding to each block in the encoding area of ​​the digital three-dimensional code.

[0102] Y20. Convert the second value into a concatenation result of the initial two-dimensional codes in the same block, and use the concatenation result to determine the first value of each initial two-dimensional code in the same block.

[0103] The conversion here refers to converting the second numerical value corresponding to the target base into the first numerical value of the base corresponding to the initial QR code.

[0104] Specifically, after obtaining the second value of each block of the digital three-dimensional code, the second value of each block is converted into the splicing result of the initial two-dimensional code in the same block according to the conversion rules in the digital three-dimensional code generation method, and then the splicing result is divided into the first value of each initial two-dimensional code in the same block using the splicing rules.

[0105] In some embodiments, the conversion rule is the reverse conversion of the initial two-dimensional code into the digital three-dimensional code of the target base, converting the second numerical value into the numerical value of the number of bits corresponding to the number information of the superimposed initial two-dimensional codes; the splicing rule is the rule for splicing according to the order of superposition.

[0106] Y30. Use the first numerical value to determine the encoding method of the initial two-dimensional code, and then identify the original information stored in the original two-dimensional code.

[0107] The encoding method refers to the rules set for constructing the identification code. For example, if the number of rows and columns of the initial two-dimensional code is consistent, and both the number of rows and columns are 21, that is, 21 code elements, then each block of the corresponding encoding area has a first value.

[0108] Specifically, after obtaining the first value of each block, the number of rows and columns corresponding to the coding area of ​​the initial QR code can be determined, and then the first value can be assigned to the corresponding block. The encoding method of the initial QR code can be determined, and after the first value is assigned to each block in the coding area, the initial QR code is obtained, and then the original information corresponding to the initial QR code contained in the digital three-dimensional code can be identified.

[0109] In this embodiment, for a digital three-dimensional code formed by superimposing multiple initial two-dimensional codes, the second value of the digital three-dimensional code is obtained, and then the first value of the superimposed initial two-dimensional code is determined, so that the original information of the initial two-dimensional code stored in the digital three-dimensional code can be identified. That is, compared with the initial two-dimensional code, the data storage capacity of the digital three-dimensional code is effectively improved, and misrecognition due to color errors will not occur.

[0110] In some embodiments, step Y20 converts the second value into a concatenation result of the initial two-dimensional codes in the same block, and uses the concatenation result to determine the first value of each initial two-dimensional code in the same block, which may include the following steps.

[0111] First, the number information and the order of superimposed initial two-dimensional codes in the functional area are obtained.

[0112] Among them, there can be multiple functional areas, for example, a first functional area and a second functional area, the first functional area is set with the number information or the superposition order of the initial QR code, and the second functional area is set with the superposition order or the number information of the initial QR code, that is, the first functional area and the second functional area are respectively set with one of the superposition order and the superposition number information.

[0113] Specifically, because the digital three-dimensional code is provided with at least a first functional area and a second functional area, and corresponding superposition order and superposition number information are respectively set in the first functional area and the second functional area, the superposition number information and superposition order of the initial two-dimensional code can be obtained from the digital three-dimensional code.

[0114] Secondly, the number information is used to convert the second value into a splicing result of the initial two-dimensional code in the same block.

[0115] Among them, the number information refers to the number of superimposed initial two-dimensional codes corresponding to the digital three-dimensional code, and the second value is converted from the splicing result of the superimposed initial two-dimensional codes in the same block. Therefore, the number information can be used to convert the second value into the splicing result.

[0116] Specifically, after obtaining the number information of the superimposed initial two-dimensional codes corresponding to the digital three-dimensional code, it can be determined how many initial two-dimensional codes are superimposed to obtain the digital three-dimensional code, and then the number of bits of the splicing result can be determined, that is, the number of bits corresponding to the number information. Therefore, the second numerical value can be converted into the splicing result of the initial two-dimensional code in the same block.

[0117] Next, the splicing result is split into the first value of each initial two-dimensional code in the same block by using the number information and the superposition order.

[0118] The stacking order refers to the stacking order of multiple initial two-dimensional codes corresponding to the digital three-dimensional code.

[0119] Specifically, after obtaining the number information and stacking order of the initial two-dimensional codes corresponding to the digital three-dimensional code, it is possible to determine the digital three-dimensional code that is composed of the same number of initial two-dimensional codes and has a clear stacking order; and then the splicing result can be split into the first numerical value of each initial two-dimensional code in the same block based on the number information and the stacking order.

[0120] In some embodiments, step Y30 uses the first numerical value to determine the encoding method of the initial two-dimensional code, and then identifies the original information stored in the original two-dimensional code.

[0121] Firstly, the pixel distribution of each block in the initial two-dimensional code is determined by using a first value.

[0122] Specifically, the pixel distribution is the distribution of black blocks and white blocks, and the first numerical value is determined by the corresponding values ​​of the black blocks and the white blocks. For example, the black block is assigned a value of 1 and the white block is assigned a value of 0. Therefore, the pixel distribution of each block in the initial QR code can be determined using the first numerical value of each block.

[0123] Secondly, the pixel distribution is used to determine the encoding method of the initial two-dimensional code, and then the original information stored in the original two-dimensional code is identified through the encoding method.

[0124] Specifically, the pixel distribution clarifies the number of rows and columns in the initial QR code, and clarifies the distribution of black blocks and white blocks in each block in the coding area. Therefore, the encoding method of the initial QR code can be determined, and then based on the encoding method of the initial QR code, the original information corresponding to the multiple original QR codes included in the digital three-dimensional code can be determined.

[0125] In this embodiment, the second value of the digital three-dimensional code is reversely converted into the first value corresponding to the initial two-dimensional code, and then the original information of the initial two-dimensional code stored in the digital three-dimensional code is identified. Compared with the initial two-dimensional code, the digital three-dimensional code has increased storage capacity and will not cause misidentification due to color errors, thereby improving recognition accuracy and thus improving data processing speed.
