Description

TECHNICAL FIELD

[0001] The present application relates to the field of terminal artificial intelligence (AI) and corresponding subfields, the field of information storage, and in particular, to a two-dimensional code encoding and decoding method and an electronic device. BACKGROUND

[0002] Nowadays, two-dimensional codes are widely used in life. Users can see two-dimensional codes everywhere in life. For example, users can use electronic devices to scan two-dimensional codes to realize payment, information acquisition, account login, and the like. Two-dimensional codes can be used to store payment information, account login information, and the like. Common two-dimensional codes include quick response (QR) codes, circular two-dimensional codes, and the like. Different versions of two-dimensional codes have different capacities for storing information.

[0003] An electronic device can encode a binary string from information (referred to as to-be-stored information, for example, a string) that needs to be stored in a two-dimensional code and then generate a two-dimensional code. For to-be-stored information, different encoding methods of an electronic device result in different lengths of binary strings. Since two-dimensional codes have limited capacities, it is desirable for an electronic device to encode to-be-stored information into a binary string that is as short as possible.

[0004] Therefore, how an electronic device encodes to-be-stored information into a binary string that is shorter in length is a problem that needs to be solved. SUMMARY

[0005] The present application provides a two-dimensional code encoding and decoding method and an electronic device. In the two-dimensional code encoding method provided by the present application, an electronic device can encode to-be-encoded text into a binary string that is shorter in length. In the two-dimensional code decoding method provided by the present application, an electronic device can decode a two-dimensional code that is encoded by using the two-dimensional code encoding method of the present application.

[0006] In a first aspect, the present application provides a two-dimensional code encoding method, which can include: an electronic device obtaining to-be-encoded text, the to-be-encoded text containing N characters, N being a positive integer; the electronic device determining a target encoding mode of each character in the N characters from X selectable encoding modes; the electronic device dividing the N characters into M character segments according to the target encoding mode of each character and determining a target encoding mode of each character segment in the M character segments; M is less than or equal to N; the electronic device encoding the M character segments according to the target encoding mode of each character segment to obtain a first binary string; and the electronic device generating a two-dimensional code of a version corresponding to the length of the first binary string from the first binary string.

[0007] By the two-dimensional code encoding method provided in the embodiments of the present application, the electronic device can encode the to-be-encoded text into a shorter binary string. When the character length in the to-be-encoded text is too long, the binary string obtained by the encoding method in the prior art exceeds the data capacity in the two-dimensional code in the prior art, resulting in that the two-dimensional code cannot be generated. By using the two-dimensional code encoding method in the embodiments of the present application, the to-be-encoded text with a longer character length can be encoded, and the two-dimensional code is generated.

[0008] In a possible implementation, the electronic device determines the target encoding mode of each character in the N characters from the X selectable encoding modes, including: the electronic device determines one or more candidate encoding modes of a first character in the N characters from the X selectable encoding modes; and the electronic device selects a candidate encoding mode with the lowest number of encoding bits from the one or more candidate encoding modes as the target encoding mode of the first character.

[0009] In this way, the electronic device can encode each character into a binary string with a lower number of bits. Thus, the electronic device can obtain a shorter binary string by encoding the to-be-encoded text.

[0010] In a possible implementation, the electronic device divides the N characters into M character segments according to the target encoding mode of each character in the N characters, and determines the target encoding mode of each character segment in the M character segments, including: the electronic device divides the characters that are continuously adjacent and have the same target encoding mode in the N characters into a character segment, to obtain the M character segments; and the electronic device determines the target encoding mode of each character segment in the M character segments based on the target encoding mode of the characters in each character segment.

Compared with one character as one character segment, the electronic device obtains fewer mode indicators in the binary string. In this way, the number of bits of the mode indicators can be saved. Thus, the electronic device can obtain a shorter binary string.

[0017] In this way, the electronic device can divide the N characters into fewer character segments, and only one mode indicator is needed for each character segment.

[0098] The embodiments of the present application relate to an application of a two-dimensional code encoding method, which can be applied in an electronic device 100. Through the method, first, the electronic device 100 can obtain a text to be encoded, which can contain one or more of numbers, capital letters, small letters, Chinese characters, Japanese characters, etc.; then the electronic device 100 can divide the text to be encoded into multiple fields, then the electronic device 100 encodes each field in the multiple fields by selecting the encoding mode with the lowest number of bits, to obtain a binary string, wherein the electronic device stores N encoding tables, each of which corresponds to an encoding mode; finally, the electronic device 100 can generate a two-dimensional code from the binary string.

[0099] First, some concepts involved in a two-dimensional code encoding method provided by the present application will be described below.

[0100] 1. Encoding mode

[0101] In the embodiments of the present application, there can be multiple encoding modes in the electronic device, each of which is used to convert the text to be encoded into binary characters. However, different encoding modes adopt different conversion methods. When an encoding mode is selected for encoding, the electronic device 100 converts the character in the text to be encoded into the index value corresponding to the character according to the encoding index table corresponding to the encoding mode, and then converts the index value into a binary character according to the encoding mode.

[0102] As shown in Table 1 below, Table 1 exemplarily lists some encoding modes and mode indicators corresponding to the encoding modes.

[0103] Table 1

[0104]

[0105] The encoding modes and the mode indicators corresponding to the encoding modes shown in Table 1 are the encoding modes and the mode indicators provided in the standard protocol of the two-dimensional code. It can be understood that more encoding modes can be provided as the standard protocol of the two-dimensional code develops. The encoding modes involved in the embodiments of the present application can not be limited to the encoding modes provided in Table 1.

[0106] In the embodiments of the present application, the mixed encoding mode Structured_Append can include multiple encoding sub-modes, and each encoding sub-mode corresponds to an encoding index table. The encoding sub-modes of the mixed encoding mode Structured_Append can be shown in Table 2. Eight sub-modes of the mixed encoding mode, i.e., the pure number encoding mode, the uppercase hexadecimal encoding mode, the lowercase hexadecimal encoding mode, the number and uppercase letter mixed encoding mode, the number and lowercase letter mixed encoding mode, the number and uppercase letter and common character mixed encoding mode, the number and lowercase letter and common character mixed encoding mode, and the number and uppercase and lowercase and special character and escape character mixed encoding mode, are shown in Table 2 by way of example.

[0107] Table 2

[0108]

[0109]

[0110] It can be understood that Table 2 is only by way of example, and the encoding sub-modes of the mixed encoding mode Structured_Append can not be limited to the eight encoding sub-modes shown in Table 2. The encoding sub-modes of the mixed encoding mode can further include a Spanish encoding mode, a Portuguese encoding mode, or a Korean encoding mode or a mixed encoding mode of different languages, etc., which are not limited herein.

[0111] In the embodiments of the present application, the numbers "0"-"9" can be referred to as number characters, the uppercase English letters "A"-"Z" can be referred to as uppercase letter characters, and the lowercase English letters "a"-"z" can be referred to as lowercase letter characters. Characters other than the numbers and the uppercase and lowercase English letters in a computer keyboard can be referred to as special characters, such as the question mark "?", the double quotation marks "", the left parenthesis "(", the right parenthesis ")", etc. The escape character refers to a backslash plus other characters, such as "\0", "\a", etc.

[0112] 2. Encoding index table

[0113] The encoding index table is used to specify the index value corresponding to a character. In an embodiment, the electronic device 100 can store an encoding index table corresponding to Base10 mode, an encoding index table corresponding to Base16_U mode, an encoding index table corresponding to Base16_L mode, an encoding index table corresponding to Base32_U mode, an encoding index table corresponding to Base32_L mode, an encoding index table corresponding to Base45_U mode, an encoding index table corresponding to Base45_L mode, and an encoding index table corresponding to Base128 mode.

[0114] For example, the encoding index table corresponding to Base10 mode can be as shown in Table 3.

[0115] Table 3

[0116] character (char) index value (value) character (char) index value (value) 0 0 5 5 1 1 6 6 2 2 7 7 3 3 8 8 4 4 9 9

[0117] As shown in Table 3, Table 3 shows an encoding index table of pure numeric characters. The encoding index table can include numeric characters "0"-"9" and index values corresponding to the numeric characters "0"-"9", respectively. For example, when a character in the text to be encoded is "0", the index value corresponding to the character in the encoding index table shown in Table 3 is "0". The index values shown in Table 3 can be decimal values, i.e., the index values "0"-"9" can be decimal values.

[0118] It can be understood that the encoding index table corresponding to Base10 mode can not be limited to the encoding index table shown in Table 3. The encoding index table corresponding to Base10 mode can change with changes in the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to Base10 mode are not limited herein.

[0119] For example, the encoding index table corresponding to Base16_U mode can be as shown in Table 4.

[0120] Table 4

[0121] character (char) index value (value) character (char) index value (value) 0 0 8 8 1 1 9 9 2 2 A 10 3 3 B 11 4 4 C 12 5 5 D 13 6 6 E 14 7 7 F 15

[0122] As shown in Table 4, Table 4 shows a hexadecimal encoding index table. The encoding index table can include hexadecimal characters (numeric characters "0"-"9" and uppercase letters "A"-"F") and index values corresponding to the hexadecimal characters, respectively. For example, the index value corresponding to the character "0" in Table 4 is "0", and the index value corresponding to the character "A" is "10". The index values shown in Table 4 can be decimal values. That is, the index values "0"-"15" in Table 4 can be decimal values.

[0123] It is understood that the encoding index table corresponding to the Base16_U mode is not limited to the encoding index table shown in Table 4. The encoding index table corresponding to the Base16_U mode can change with the change of the QR code encoding protocol. The specific form and content of the encoding index table corresponding to the Base16_U mode are not limited here.

[0124] For example, the encoding index table corresponding to the Base16_L mode can be shown in Table 5 below.

[0125] Table 5

[0126] character (char) index value (value) character (char) index value (value) 0 0 8 8 1 1 9 9 2 2 a 10 3 3 b 11 4 4 c 12 5 5 d 13 6 6 e 14 7 7 f 15

[0127] As shown in Table 5, this table displays a hexadecimal encoding index. This index can include the index values ​​corresponding to each hexadecimal character (the numeric characters "0"-"9", and the lowercase letters "a"-"f"). For example, the index value corresponding to the character "0" in Table 5 is "0", and the index value corresponding to the character "a" is "10". The index values ​​shown in Table 5 can also be decimal values. That is, index values ​​"0" through "15" in Table 5 can be decimal values.

[0128] It is understood that the encoding index table corresponding to the Base16_L mode is not limited to the encoding index table shown in Table 5. The encoding index table corresponding to the Base16_L mode can change with the change of the QR code encoding protocol. The specific form and content of the encoding index table corresponding to the Base16_L mode are not limited here.

[0129] For example, the encoding index table corresponding to the Base32_U mode can be shown in Table 6 below.

[0130] Table 6

[0131]

[0132] As shown in Table 6, Table 6 presents the encoding index table for uppercase letters and special characters. This encoding index table can include uppercase letters "A"-"Z" and the special character "SP", as well as the index values ​​corresponding to the uppercase letters "A"-"Z" and the index value corresponding to the special character "SP". For example, in Table 6, the index value corresponding to the uppercase character "A" could be "0", and the index value corresponding to the special character "SP" could be "26". The index values ​​shown in Table 6 can be decimal values. That is, the index values ​​"0"-"31" in Table 6 can be decimal values.

[0133] It can be understood that the encoding index table corresponding to the Base32_U mode can not be limited to the encoding index table shown in Table 6. The encoding index table corresponding to the Base32_U mode can change with the change of the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to the Base32_U mode are not limited here.

[0134] Exemplarily, the encoding index table corresponding to the Base32_L mode can be as shown in Table 7.

For example, in Table 7, the index value corresponding to the lowercase letter "a" can be "0", and the index value corresponding to the special character "SP" can be "26". The index values shown in Table 7 can be decimal values. That is, the index values "0"-"31" in Table 7 can be decimal values.

[0138] It can be understood that the encoding index table corresponding to the Base32_L mode can not be limited to the encoding index table shown in Table 7. The encoding index table corresponding to the Base32_L mode can change with the change of the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to the Base32_L mode are not limited here.

[0139] Exemplarily, the encoding index table corresponding to the Base45_U mode can be as shown in Table 8.

[0142] As shown in Table 8, Table 8 shows the encoding index table of numbers, uppercase letters and common characters. The encoding index table can include number characters "0"-"9", and uppercase letters "A"-"Z" and special characters (such as "?", "$", "%", etc.), and the index values corresponding to the number characters "0"-"9" respectively, the index values corresponding to the uppercase letters "A"-"Z" respectively, the index values corresponding to the common characters. For example, in Table 8, the index value corresponding to the number character "0" can be "0", the index value corresponding to the uppercase letter "A" can be "10", and the index value corresponding to the special character "?" can be "36". The index values shown in Table 8 can be decimal values. That is, the index values "0"-"44" in Table 8 can be decimal values.

[0143] It can be understood that the encoding index table corresponding to the Base45_U mode can not be limited to the encoding index table shown in Table 8. The encoding index table corresponding to the Base45_U mode can change with the change of the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to the Base45_U mode are not limited here.

[0144] Exemplarily, the encoding index table corresponding to the Base45_L mode can be as shown in Table 9.

[0145] Table 9

[0146]

[0147]

[0148] As shown in Table 9, Table 9 shows the encoding index table of the number, lowercase letter and special character. The encoding index table can include the index values corresponding to the number characters “0”-“9”, the lowercase letters “a”-“z” and the commonly used characters (for example, “?”, “!”, “=” and the like), and the number characters “0”-“9”, respectively. The index values corresponding to the lowercase letters “a”-“z”, respectively, and the index values corresponding to the commonly used characters. For example, in Table 9, the index value corresponding to the number character “0” can be “0”, the index value corresponding to the lowercase letter “a” can be “10”, and the index value corresponding to the commonly used character “?” can be “43”. The index values shown in Table 9 can be decimal values. That is, the index values “0”-“44” in Table 9 can be decimal values.

[0149] It can be understood that the encoding index table corresponding to the Base45_L mode can not be limited to the encoding index table shown in Table 9. The encoding index table corresponding to the Base45_L mode can change with the change of the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to the Base45_L mode are not limited here.

[0150] Exemplarily, the encoding index table corresponding to the Base128 mode can be as shown in Table 10.

[0151] Table 10

[0152]

[0153]

[0154] As shown in Table 10, Table 10 shows an encoding index table of digits, lowercase letters, uppercase letters and common characters, and escape characters. The encoding index table can include digits "0"-"9", and lowercase letters "a"-"z", uppercase letters "A"-"Z" and common characters (for example, "?", "!", "=", and the like), escape characters, and index values corresponding to the digits "0"-"9", respectively, index values corresponding to the lowercase letters "a"-"z", respectively, index values corresponding to the uppercase letters "A"-"Z", respectively, and index values corresponding to the common characters and escape characters, respectively.

The index values shown in Table 10 can be decimal values. That is, the index values "0"-"127" in Table 10 can be decimal values.

[0155] It can be understood that the encoding index table corresponding to the Base128 mode can not be limited to the encoding index table shown in Table 10. The encoding index table corresponding to the Base128 mode can change with the change of the two-dimensional code encoding protocol. The specific form and content of the encoding index table corresponding to the Base128 mode are not limited here.

[0156] It can be understood that the encoding index table stored by the electronic device 100 in the embodiments of the present application can not be limited to the encoding index tables shown in Tables 3-10. The electronic device 100 can store more encoding index tables, which are not limited here.

[0157] The encoding binary bits and the mode indicators corresponding to the encoding sub-modes (for example, the Base10 mode, the Base16_U mode, the Base16_L mode, the Base32_U mode, the Base32_L mode, the Base45_U mode, the Base45_L mode, and the Base128 mode) of the mixed encoding mode Structured_Append involved in the embodiments of the present application can be as shown in Table 11.

[0158] Table 11

[0159]

[0161] As shown in Table 11, Table 11 exemplarily shows the binary bits and the mode indicators corresponding to the Base10 mode, the Base16_U mode, the Base16_L mode, the Base32_U mode, the Base32_L mode, the Base45_U mode, the Base45_L mode, the Base128 mode, and the like, respectively. It can be understood that the encoding sub-modes shown in Table 11, and the binary bits and the mode indicators corresponding to the encoding sub-modes are only for illustration, and the number of the encoding sub-modes and the binary bits and the mode indicators corresponding to each encoding sub-mode are not limited in the embodiments of the present application.

[0162] It can be understood that the encoding index table in the embodiments of the present application can be more, and is not limited to the encoding index tables shown in Tables 3-10.

[0163] The electronic device 100 can select any one of the above encoding modes to encode the text to be encoded into a binary string, and then the electronic device 100 can generate a two-dimensional code corresponding to a version of the two-dimensional code according to the binary string. The two-dimensional code involved in the embodiments of the present application can include different types of two-dimensional codes, and the same type but different versions of two-dimensional codes. For example, Figure 1 the QR (Quick Response) code shown in (a), (b), and (c) of FIG. 1, Figure 2 the two-dimensional codes shown in (a), (b), and (c) of FIG. 2, Figures 3A-3F the circular two-dimensional codes shown in (a), (b), (c), (d), (e), and (f) of FIG. 3. It can be understood that the data capacity that can be stored by different types of two-dimensional codes, and the same type but different versions of two-dimensional codes is generally different. The greater the data capacity that can be stored by a two-dimensional code, the longer the length of the binary string that can be stored by the two-dimensional code.

Figures 3A-3F The circular two-dimensional code shown in FIG. 3 can be referred to as a Hongmeng two-dimensional code in the embodiments of the present application. It can be understood that the number of the encoding sub-modes, and the binary bits and the mode indicators corresponding to each encoding sub-mode are not limited in the embodiments of the present application. Figures 3A-3FThe name of the illustrated two-dimensional code is not limited.

[0166] It can be understood that, Figure 1 , Figure 2 and Figures 3A-3F The two-dimensional codes shown in the above are only for illustration, and the types of two-dimensional codes and the versions of a certain type of two-dimensional code involved in the embodiments of the present application can be more, not limited to Figure 1 , Figure 2 The two-dimensional codes shown in Figures 3A-3F The two-dimensional codes shown in Figures 3A-3F are taken as examples for illustration.

[0167] Exemplarily, Figures 3A-3F The data capacity of the different versions of two-dimensional codes shown in the above can be as shown in Table 12.

[0168] Table 12

[0169]

[0170]

[0171] As shown in Table 12, Figure 3A The data capacity of the version one two-dimensional code shown in the above is 249 bits, and 19 valid bytes can be stored. Figure 3B The data capacity of the version two two-dimensional code shown in the above is 408 bits, and 34 valid bytes can be stored. Figure 3C The data capacity of the version three two-dimensional code shown in the above is 624 bits, and 55 valid bytes can be stored. Figure 3D The data capacity of the version four two-dimensional code shown in the above is 872 bits, and 80 valid bytes can be stored. Figure 3E The data capacity of the version five two-dimensional code shown in the above is 1152 bits, and 108 valid bytes can be stored. Figure 3F The data capacity of the version six two-dimensional code shown in the above is 1464 bits, and 136 valid bytes can be stored.

[0172] Based on the above explanation of the basic concepts involved in the embodiments of the present application, a two-dimensional code encoding method provided by the embodiments of the present application is introduced below. As shown in Figure 4 , Figure 4 a two-dimensional code encoding method flow provided by the embodiments of the present application is shown, which can include the following steps:

[0173] S101, the electronic device 100 acquires the to-be-encoded text, and the to-be-encoded text can contain N characters.

[0174] The electronic device 100 can obtain a to-be-encoded text, and the N characters of the to-be-encoded text can be one or more of a numeric character, an English uppercase letter, an English lowercase letter, a Chinese character, Japanese, Korean, a general character, a special character, an escape character, and the like. Specifically, the to-be-encoded text can be a string of numbers, a piece of text (Chinese, English, Japanese, Korean, and the like), a link, and the like, such as "12345678", "ABCD", "abcdef", "a kind of two-dimensional code encoding method", "https: / / zh.wikipedia.org / wiki / %E4%BD%8D%E5%85%83", and the like.

[0175] The to-be-encoded text obtained by the electronic device 100 can be input by a user in the electronic device 100, can be generated by the electronic device 100 based on information input by the user, or can be obtained by the electronic device 100 from another electronic device, and the like, which is not limited herein.

[0176] In S102, the electronic device 100 determines one or more candidate encoding modes for each character in the N characters from X available encoding modes, and selects a candidate encoding mode with the lowest number of encoding bits from the one or more candidate encoding modes as a target encoding mode for each character, where X is a positive number.

[0177] The electronic device 100 stores X encoding modes, and each encoding mode has a corresponding number of encoding bits. For example, the eight encoding modes shown in Table 11, Base10 mode, Base16_U mode, Base16_L mode, Base32_U mode, Base32_L mode, Base45_U mode, Base45_L mode, and Base128 mode, and the corresponding number of encoding bits (i.e., the number of bits in the table, also referred to as the number of binary bits) of each encoding mode.

[0178] In the embodiments of the present application, X is a positive number, and X can be equal to 8 or 10, which is not limited herein. Hereinafter, X is equal to 8 is taken as an example for illustration. That is, hereinafter, the electronic device 100 is configured with eight encoding modes as shown in Table 11 is taken as an example for illustration.

[0179] The encoding mode configured in the electronic device 100 can be referred to as an optional encoding mode. The electronic device 100 can determine one or more candidate encoding modes corresponding to each character in the text to be encoded from X encoding modes. When an encoding mode A corresponds to an encoding index table including a character A, the encoding mode A can be referred to as a candidate encoding mode of the character A. For example, for the character "0", the Base10 mode, the Base16_U mode, the Base16_L mode, the Base32_U mode, the Base32_L mode, the Base45_U mode, the Base45_L mode, the Base128 mode, and the like correspond to the encoding index tables including the character "0", and thus the Base10 mode, the Base16_U mode, the Base16_L mode, the Base32_U mode, the Base32_L mode, the Base45_U mode, the Base45_L mode, and the Base128 mode can be referred to as the candidate encoding modes of the character "0".

[0180] As can be seen from Table 11, the Base10 mode has an encoding bit number of 3. The Base16_U mode has an encoding bit number of 4. The Base16_L mode has an encoding bit number of 4. The Base32_U mode has an encoding bit number of 5. The Base32_L mode has an encoding bit number of 5. The Base45_U mode has an encoding bit number of 6. The Base45_L mode has an encoding bit number of 6. The Base128 mode has an encoding bit number of 7. The Base10 mode has the lowest encoding bit number, and thus the electronic device 100 can select the Base10 mode as the target encoding mode of the character "0" from the candidate modes of the character "0".

[0181] The target encoding mode of each character in the N characters of the text to be encoded can be the same or different. For example, when the N characters are "0124FEAabcd" (in this case, N is equal to 11). Referring to the description of the determination of the target encoding mode of the character "0" by the electronic device 100, the electronic device 100 can determine the target encoding mode of the character "0" as the Base10 mode, the target encoding mode of the character "1" as the Base10 mode, the target encoding mode of the character "2" as the Base10 mode, the target encoding mode of the character "4" as the Base10 mode, the target encoding mode of the character "F" as the Base16_U mode, the target encoding mode of the character "E" as the Base16_U mode, the target encoding mode of the character "A" as the Base16_U mode, the target encoding mode of the character "a" as the Base16_L mode, the target encoding mode of the character "b" as the Base16_L mode, the target encoding mode of the character "c" as the Base16_L mode, and the target encoding mode of the character "d" as the Base16_L mode.

[0182] It can be understood that N is an integer greater than 1, and the embodiments of the present application do not limit the specific value of N. For example, N can be equal to 1, and N can also be equal to 11.

[0183] In S103, the electronic device 100 divides the N characters into M character segments according to the target encoding mode of each character in the N characters, and determines the target encoding mode of the M character segments, each of which contains one or more characters.

[0184] The electronic device 100 can divide the N characters into M character segments according to the target encoding mode of each character in the N characters. Each of the M character segments contains one or more characters. M can be less than or equal to N. The electronic device 100 can also determine the target encoding mode of the character segment according to the target encoding mode of each character in the character segment.

[0185] The electronic device 100 can configure M to be equal to N in the system. The electronic device 100 can also configure M to be less than N.

[0186] The electronic device 100 can divide the N character segments into M character segments in various ways. Hereinafter, the electronic device 100 will be taken as an example to specifically illustrate how the electronic device divides the N characters into M character segments according to the target encoding mode of each character in the N characters, and determines the target encoding mode of the M character segments, by taking the N characters "0124FEAabcd" in the above as an example.

[0187] Alternatively, in a possible implementation, the electronic device 100 can divide the character string "0124FEAabcd" composed of 11 characters into 11 character segments, that is, each character segment contains one character. The target encoding mode of each character segment is the target encoding mode of the character contained in the character segment. The target encoding mode of each character in the character string "0124FEAabcd" and the encoding mode of the character segment can be as shown in Table 13.

[0188] Table 13

[0189]

[0190]

[0191] As shown in Table 13, the electronic device 100 can divide the string "0124FEAabcd" into 11 character segments, i.e., character segment "0", character segment "1", character segment "2", character segment "4", character segment "F", character segment "E", character segment "A", character segment "a", character segment "b", character segment "c", and character segment "d". The target encoding mode of the character segment "0" is the Base10 mode. The target encoding mode of the character segment "1" is the Base10 mode. The target encoding mode of the character segment "2" is the Base10 mode. The target encoding mode of the character segment "4" is the Base10 mode. The target encoding mode of the character segment "F" is the Base16_U mode. The target encoding mode of the character segment "E" is the Base16_U mode. The target encoding mode of the character segment "A" is the Base16_U mode. The target encoding mode of the character segment "a" is the Base16_L mode. The target encoding mode of the character segment "b" is the Base16_L mode. The target encoding mode of the character segment "c" is the Base16_L mode. The target encoding mode of the character segment "d" is the Base16_L mode.

[0192] Alternatively, in a possible implementation, the electronic device 100 can divide the characters that are continuous adjacent and have the same target encoding mode in the N characters into one character segment, and finally obtain M character segments. For example, in the string "0124FEAabcd", the characters "0", "1", "2", and "4" are continuous adjacent (i.e., the character "0" is adjacent to the character "1", the character "1" is adjacent to the character "2", and the character "2" is adjacent to the character "4"), and have the same target encoding mode. The electronic device 100 can divide the characters "0", "1", "2", and "4" into one character segment "0124". The target encoding mode of the character segment "0124" is the target encoding mode of the characters "0", "1", "2", and "4", i.e., the Base10 mode. The target encoding mode of each character in the string "0124FEAabcd" and the encoding mode of the character segment can be as shown in Table 14.

[0193] Table 14

[0194]

[0195] As shown in Table 13, the electronic device 100 can divide the string "0124FEAabcd" into 3 character segments, i.e., a character segment "0124", a character segment "FEA", and a character segment "abcd". The character segment "0124" contains 4 characters, and the target encoding mode of each of the 4 characters is the Base10 mode. Therefore, the target encoding mode of the character segment "0124" can also be the Base10 mode. The character segment "FEA" contains 3 characters, and the target encoding mode of each of the 3 characters is the Base16_U mode. Therefore, the target encoding mode of the character segment "FEA" can also be the Base16_U mode. The character segment "abcd" contains 4 characters, and the target encoding mode of each of the 4 characters is the Base16_L mode. Therefore, the target encoding mode of the character segment "abcd" can also be the Base16_L mode.

[0196] Optionally, in a possible implementation, the electronic device 100 can divide the N characters into M character segments, and the number of characters in each of the M character segments is greater than or equal to a preset number.

[0197] Further, the electronic device 100 can divide the character segments in the order of the arrangement of the N characters. The electronic device 100 can divide the characters that are continuously adjacent to each other and have the same target encoding mode into a character segment when the number of the characters is greater than or equal to a preset number. The electronic device 100 can divide the characters that are continuously adjacent to each other but have different target encoding modes into a character segment when the number of the characters is equal to or greater than the preset number. For example, when the preset number is 4, the electronic device 100 can divide the string "0124FEAabcd" into character segments as shown in Table 15.

[0198] Table 15

[0199]

[0200] As shown in Table 15, the characters "0", "1", "2", "4" in the string "0124FEAabcd" are continuous and adjacent, and the target encoding mode is the same, so the electronic device 100 can divide the characters "0", "1", "2", "4" into a character segment "0124". The characters "F", "E", "A" in the string "0124FEAabcd" are continuous and adjacent, and the encoding mode is different, but the three characters "F", "E", "A" do not satisfy the preset number, so the electronic device 100 can divide the characters "a", "b", "c", "d" after the character "A" into a character segment "FEAabcd" together with the characters "F", "E", "A". The target encoding mode of the characters "F", "E", "A" is Base16_U mode, and the target encoding mode of the characters "a", "b", "c", "d" is Base16_L mode. The target encoding mode of the character segment "FEAabcd" can be Base128 mode, which requires both encoding of English uppercase letters and encoding of English lowercase letters.

[0201] Alternatively, the electronic device 100 can divide the string "0124FEAabcd" into character segments "0124", "FEAa", and "bcd", and the target encoding mode of the character segment "0124" is Base10 mode. The target encoding mode of the character segment "FEAa" is Base128 mode. Alternatively, in a possible implementation, the electronic device counts from the 1st character of N characters, and when the number of characters is greater than or equal to the preset number, the target encoding mode of the u-th character is different from the target encoding mode of the (u-1)th character, the electronic device 100 divides the 1st character to the (u-1)th character into a character segment. Then, the electronic device 100 counts from the u-th character again, and when the number of characters is greater than or equal to the preset number, the target encoding mode of the v-th character is different from the target encoding mode of the (v-1)th character, the electronic device 100 divides the u-th character and the (v-1)th character into a character segment. In turn, the electronic device 100 divides the N characters into M character segments.

[0202] Further, in a possible implementation, the electronic device can use two pointers to count and identify different target encoding modes in the string, respectively. For example, Figure 5 The string "10ABCD1234aaaa" shown in Table 15, and the pointer i and the pointer j. The pointer i is used for counting, and the pointer j is a position pointer used to identify a new target encoding mode. Taking the preset number equal to 4 as an example, as shown in Table 15, the electronic device 100 counts from the 1st character of the string "10ABCD1234aaaa" and divides the 1st character to the 4th character into a character segment "10ABCD". The target encoding mode of the character segment "10ABCD" is Base10 mode. Then, the electronic device 100 counts from the 5th character of the string "10ABCD1234aaaa" and divides the 5th character to the 8th character into a character segment "1234". The target encoding mode of the character segment "1234" is Base16_U mode. Then, the electronic device 100 counts from the 9th character of the string "10ABCD1234aaaa" and divides the 9th character to the 12th character into a character segment "aaaa". The target encoding mode of the character segment "aaaa" is Base16_L mode. Figure 5As shown, first, the pointer j is at the position j1, i.e., the first character "1", and the pointer i starts counting from the first character "1" of the string "10ABCD1234aaaa". When the pointer j is at the position j2, i.e., the seventh character "1", the seventh character "1" is different from the target encoding mode of the sixth character "D", the electronic device 100 divides the first six characters into one character segment, i.e., the character segment "10ABCD". The pointer i starts counting again from the seventh character "1", and at j = j3, the electronic device 100 identifies that the target encoding mode of the thirteenth character "a" is different from the target encoding mode of the twelfth character "4", the electronic device 100 divides the seventh character to the eleventh character, i.e., four characters, into one character segment, i.e., the character segment "1234", and the electronic device 100 divides the remaining four characters, i.e., the four adjacent characters "a", into one character segment "aaaa".

[0203] It can be understood that when the electronic device 100 divides the N characters into M-1 character segments according to the above steps, if the number of remaining characters is less than the preset number, the electronic device 100 can also divide the characters less than the preset number into the Mth character segment. That is, the number of characters in the last obtained character segment of the M character segments can be less than the preset number.

[0204] It can be understood that the preset number can be configured by the system of the electronic device 100, and the experience value of the preset number is 4. However, the embodiment of the present application does not limit the specific value of the preset number, and the preset number can be 4, 5 or other values.

[0205] S104, the electronic device 100 encodes the M character segments according to the target encoding of the M character segments to obtain a binary string S.

[0206] When the electronic device 100 divides the N characters into M character segments and determines the target encoding mode of the M character segments, the electronic device 100 can encode each character segment according to the target encoding mode of each character segment, and finally obtain a binary string S.

[0207] In a possible implementation, the format of the binary string obtained by encoding the character segment according to the target encoding mode of the character segment can be as follows Figure 6AAs shown. The binary string 600 obtained by encoding the character segment can include a mode indicator 60a, a data length 60b, and data 60c. The mode indicator 60a is used to identify the encoding mode of the binary string 600. The data length 60b is used to indicate the length of the data 60c in the binary string 600. The data 60c is the binary character data obtained by encoding the characters in the original character segment according to the target mode. The character segment "0124" shown in Table 14 above is used as an example for illustration. The character segment "0124" is encoded according to the target encoding mode, namely Base10 mode, to obtain the binary string S1 as shown in Table 16 below.

[0208] Table 16

[0209]

[0210] As shown in Table 16, the target encoding mode for the character segment "0124" is Base10. The result of encoding "0124" in Base10 mode is "000001010100". After adding the mode indicator and length, the final encoding result of the character segment "0124" is the binary string S1 "001100000001010100". Here, the character "0" corresponds to the decimal value "0" in the Base10 mode encoding index table. Since the Base10 mode encoding has 3 bits, the decimal value "0" can be converted to the three-bit binary character "000". Therefore, the character "0" can be encoded as the binary character "000" according to Base10 mode. Similarly, the character "1" can be encoded as the binary character "001" according to Base10 mode. The character "2" can be encoded as the binary character "010" according to Base10 mode. The character "4" can be encoded as the binary character "100" according to Base10 mode.

[0211] Furthermore, the format of the binary string S resulting from the encoding of N characters in the text to be encoded can be as follows: Figure 6B As shown. Figure 6B As shown, binary string 60 can be composed of the encoding results of multiple character segments (e.g., binary string 60 (including pattern indicator, length, and data), binary string 601 (including pattern indicator, length, and data), binary string 602 (including pattern indicator, length, and data), etc.). The following example illustrates this with the segmentation results of N characters "0124FEAabcd" and N characters "0124FEAabcd" shown in Table 14. The encoding result of N characters "0124FEAabcd", i.e., binary string S, can be shown in Table 17 below.

[0212] Table 17

[0213]

[0214] As shown in Table 17, the N characters "0124FEAabcd" can be divided into the character segment "0124", the character segment "FEA", and the character segment "abcd". The character segment "0124" can be encoded according to the target mode, i.e., the Base10 mode, to obtain the binary string S1 "001100000001010100". The character segment "FEA" can be encoded according to the target mode, i.e., the Base16_U mode, to obtain the binary string S2 "010011111111101010". The character segment "abcd" can be encoded according to the target encoding mode, i.e., the Base16_L mode, to obtain the binary string S3 "001100101010111101". The encoding result of the N characters "0124FEAabcd", i.e., the binary string S, can be composed of the binary string S1, the binary string S2, and the binary string S3. Therefore, the binary string S can be "001100000001010100010011111111101010001100101010111101". The encoding result of each character in the character segment "0124", the character segment "FEA", and the character segment "abcd" can refer to the description of the encoding result of the character "0" in the character segment "0124" in Table 16, and will not be described here.

[0215] It can be understood that, since the Base10 mode, the Base16_U mode, and the Base16_L mode are sub-modes of the Structured_Append mixed encoding mode, the binary string S obtained after final encoding can be prefixed with the mode indicator "0011" of the Structured_Append mixed encoding mode. Optionally, the total length (11 characters in total) of the string can also be indicated after the mode indicator "0011" of the Structured_Append mixed encoding mode. Therefore, the final binary string S can be "00111011001100000001010100010011111111101010001100101010111101".

[0216] Optionally, when the number of characters in the M character segments is fixed, the format of the encoding result of the character segment can also be the encoding format as shown in Table 18. Compared with the encoding format as shown in Table 17, Figure 6C Figure 6A Figure 6C ​​The data length can not be included in the binary string. For example, the character segment shown in Table 13 includes only one character in each character segment, and the format of the encoding result of the character segment, i.e., the format of the binary string obtained after encoding, can be Figure 6C as shown in Table 13. The format of the encoding result of the string shown in Table 13 can be as shown in Figure 6D . Figure 6D The string 70 in the character segment can be composed of a string obtained by encoding a plurality of character segments (for example, string 700 (including a mode indicator and data), string 701 (including a mode indicator and data), string 702 (including a mode indicator and data), and the like). Reference can be made to the description of Figure 6A and Figure 6B above, which will not be repeated here.

[0217] It can be understood that the format of the binary string in the embodiments of the present application is not limited to the formats shown in Figure 6B and Figure 6D . The format of the binary string can have more forms, for example, the format of the binary string can be that the data is after the mode indicator, i.e., the format of "mode indicator 1 mode indicator 2 mode indicator 3 data 1 data 2 data 3", and the like, where mode indicator 1 is an encoding mode indication of data 1, mode indicator 2 is an encoding mode indication of data 2, and mode indicator 3 is an encoding mode indication of data 3, which is not limited here.

[0218] It can be understood that the division result of N characters can be different, and the binary string S obtained after final encoding can be different. For example, the N characters "0124FEAabcd" are divided according to the character segments shown in Table 13 to obtain the encoding result, which can be different from the encoding result of the character segments shown in Table 14.

[0219] It can be understood that the encoding bit number of the character length in the above Tables 16 and 17 is 3, which is only for illustration. When the character length of the character segment and the string is longer, the encoding bit number of the character length is higher. When the encoding bit number is 3, the character segment or the string of up to 7 characters can be represented. When the encoding is 4, the character segment or the string of up to 15 characters can be represented. The encoding bit number of the character length in the embodiments of the present application can be set to a fixed value. That is, the character length of each character segment can be encoded according to the set encoding bit number. The encoding bit number of the character length in the embodiments of the present application is not limited, for example, it can be 3 as shown in Tables 16 and 17, it can be 4, it can be 8, it can be higher, and the like.

[0220] S105, the electronic device 100 generates a target two-dimensional code of a corresponding version according to the length of the binary string S.

[0221] Since the data capacity of different versions of the two-dimensional code is different, the electronic device 100 needs to generate a corresponding version of the two-dimensional code according to the length of the binary string S. The target two-dimensional code corresponding to the length of the binary string S refers to the data capacity of the target two-dimensional code of the version being greater than or equal to the length of the binary string S.

[0222] Optionally, the electronic device can encrypt and compress the binary string S to obtain a binary string S', and the electronic device can generate a corresponding version of the two-dimensional code according to the length of the binary string S'. In this way, the security of the string can be improved, and the storage space of the string can be improved.

[0223] In a possible implementation, as shown in Figure 7 , the electronic device 100 generates a corresponding version of the two-dimensional code according to the length of the binary string S, which can specifically include the following steps:

[0224] S1051, the electronic device 100 can determine the target version of the target two-dimensional code according to the length of the binary string.

[0225] Different versions provide different amounts of stored data. The longer the binary string is, the more data needs to be stored. The electronic device 100 determines the target version of the two-dimensional code to be generated according to the length of the binary string.

[0226] The following describes six versions of the two-dimensional code shown in Figures 3A-3F , and briefly introduces the six versions of the two-dimensional code in Figures 3A-3F . It should be noted that when the following describes the dot-shaped code elements in the six versions of the two-dimensional code, the dot-shaped code elements here are one storage location, and cannot be equated with the code elements in the generated two-dimensional code.

[0227] Version one, the coding area of the two-dimensional code includes four concentric circular areas.

[0228] As shown in Figure 8A , the image area 401 of the two-dimensional code in Figure 8A indicates the brand type (Harmony OS) of the two-dimensional code. It can be seen that in Figure 8A , the image area 401 is circular.

[0229] The center point of the image area 401 is taken as the center of a circle, and the encoding area 402 includes four concentric circular areas, and each of the four concentric circular areas is uniformly arranged with dot code elements. The distance between two adjacent dot code elements in each of the four concentric circular areas (or the arc length formed by the centers of two adjacent dot code elements) is the same. Each dot code element can store information, and the information stored in each dot code element can indicate that, in terms of color, if a dot code element stores first information (for example, 1 in binary), the dot code element is colored in a first color (for example, black), and if a dot code element stores second information (for example, 0 in binary), the dot code element is colored in a second color (for example, white, for example, transparent) or is not colored.

[0230] There is a first interval between the image area 401 and the encoding area 402, and there is a second interval between each of two adjacent concentric circular areas in the encoding area 402. Each of the concentric circular areas is composed of an inner circular ring and an outer circular ring, the width of each of the concentric circular areas is the difference between the radii of the inner circular ring and the outer circular ring, and the second interval is the interval between the outer circular ring of the small concentric circular area and the inner circular ring of the large concentric circular area in the two adjacent concentric circular areas. There is a third interval between two adjacent dot code elements in each of the concentric circular areas. For example, in Figure 8A , if the diameter of a dot code element is 1, the radius of the image area 401 is 10, the interval between the image area 401 and the encoding area 402 is 1, that is, the first interval is 1 or the diameter of a dot code element, the width of each of the concentric circular areas in the encoding area 402 is 1, that is, the diameter of a dot code element, the interval between each of two adjacent concentric circular areas in the encoding area 402 is 1, that is, the second interval is 1 or the diameter of a dot code element, and the interval between two adjacent dot code elements in each of the concentric circular areas can be 0 or a circular arc with the same central angle, that is, the third interval can be 0 or a circular arc with the same central angle.

[0231] In some embodiments, the four concentric circular areas are divided into upper half areas and lower half areas, and there is a fourth interval between the upper half areas and the lower half areas. For example, in Figure 8A , if the diameter of a dot code element is 1, the interval between the upper half areas and the lower half areas is 5.

[0232] The locator area is in the two-dimensional code, for example, in Figure 8A , the locator area includes three main locators 403 and an auxiliary locator 404, the outer contours of the three main locators 403 and the auxiliary locator 404 are all circular, the centers of the three main locators 403 are all in the penultimate concentric circular area in the periphery, and the diameter of a dot code element is 1, so the diameter of the three main locators 403 is 5.

[0233] Version two, the coding area of the two-dimensional code includes five concentric circular areas.

[0234] As shown in Figure 8B , the image area 411 of the two-dimensional code in Figure 8B indicates the brand type (Harmony OS) of the two-dimensional code. With the center point of the image area 411 as the center, the coding area 412 includes five concentric circular areas, and each concentric circular area is uniformly arranged with dot-shaped code elements. The distance between the centers of two adjacent dot-shaped code elements in each concentric circular area (or the arc length formed by the centers of every two adjacent dot-shaped code elements) is the same.

[0235] There is a first interval between the image area 411 and the coding area 412, a second interval between every two adjacent concentric circular areas in the coding area 412, and a third interval between two adjacent dot-shaped code elements in each concentric circular area. For example, in Figure 8B , if the diameter of a dot-shaped code element is 1, the radius of the image area 411 is 10, the interval between the image area 411 and the coding area 412 is 2, that is, the first interval is 2 or the diameter of two dot-shaped code elements; the interval between every two adjacent concentric circular areas in the coding area 412 is 1, that is, the second interval is 1 or the diameter of one dot-shaped code element; and the interval between two adjacent dot-shaped code elements in each concentric circular area can be 0 or a circular arc with the same central angle, that is, the third interval can be 0 or a circular arc with the same central angle.

[0236] In some embodiments, the four concentric circular areas are divided into upper and lower half areas, and there is a fourth interval between the upper and lower half areas. For example, in Figure 8B , if the diameter of a dot-shaped code element is 1, the interval between the upper and lower half areas is 5.

[0237] The locator area is in the two-dimensional code, for example, in Figure 8B , it includes three main locators 413 and one auxiliary locator 414, and the outer contours of the three main locators 413 and the auxiliary locator 414 are all circular. The centers of the main locators 413 are all in the penultimate concentric circular area in the periphery, and the diameter of a dot-shaped code element is 1, so the diameter of the three main locators 413 is 5.

[0238] Version three, the coding area of the two-dimensional code includes eight concentric circular areas.

[0239] As shown in Figure 8C , the image area 411 of the two-dimensional code in Figure 8CThe image area 421 of the two-dimensional code in FIG. 4A indicates the brand type (harmony OS) of the two-dimensional code. The encoding area 422 includes 8 concentric circular areas with the center point of the image area 421 as the center, and each of the concentric circular areas is uniformly arranged with dot code elements. The distance between the centers of two adjacent dot code elements in each of the concentric circular areas (or the arc length formed by the centers of two adjacent dot code elements) is the same.

[0240] There is a first interval between the image area 421 and the encoding area 422, a second interval between each of the two adjacent concentric circular areas in the encoding area 422, and a third interval between each of the two adjacent dot code elements in each of the concentric circular areas. For example, in Figure 8C , if the diameter of a dot code element is 1, the radius of the image area 421 is 10, the interval between the image area 421 and the encoding area 422 is 2, that is, the first interval is 2 or the diameter of two dot code elements; the interval between each of the two adjacent concentric circular areas in the encoding area 422 is less than 1, that is, the second interval can be between 0 and 1; and the interval between each of the two adjacent dot code elements in each of the concentric circular areas can be 0 or a circular arc with the same central angle, that is, the third interval can be 0 or a circular arc with the same central angle.

[0241] In some embodiments, the 8 concentric circular areas are divided into upper half areas and lower half areas, and there is a fourth interval between the upper half areas and the lower half areas. For example, in Figure 8C , if the diameter of a dot code element is 1, the interval between the upper half areas and the lower half areas is 5.

[0242] The locator area is in the two-dimensional code, for example, in Figure 8C , the two-dimensional code includes three main locators 423 and an auxiliary locator 424, and the outer contours of the three main locators 423 and the auxiliary locator 424 are circular. The centers of the main locators 423 are in the penultimate concentric circular area in the periphery, and the diameter of a dot code element is 1. Therefore, the diameter of the three main locators 423 is 5.

[0243] Version four, the encoding area of the two-dimensional code includes 10 concentric circular areas.

[0244] As shown in Figure 8D , Figure 8D The image area 431 of the two-dimensional code in FIG. 4B indicates the brand type (harmony OS) of the two-dimensional code. The encoding area 432 includes 10 concentric circular areas with the center point of the image area 431 as the center, and each of the concentric circular areas is uniformly arranged with dot code elements. The distance between the centers of two adjacent dot code elements in each of the concentric circular areas (or the arc length formed by the centers of two adjacent dot code elements) is the same.

[0245] There is a first interval between the image area 431 and the encoding area 432, a second interval between each two adjacent concentric circular areas in the encoding area 432, and a third interval between two adjacent dot-shaped code elements in each concentric circular area. For example, in Figure 8D , if the diameter of one dot-shaped code element is 1, the radius of the image area 431 is 10, the interval between the image area 431 and the encoding area 432 is 2, that is, the first interval is 2 or the diameter of two dot-shaped code elements; the interval between each two adjacent concentric circular areas in the encoding area 432 is less than 1, that is, the second interval can be between 0 and 1; the interval between two adjacent dot-shaped code elements in each concentric circular area can be 0 or a circular arc with the same central angle, that is, the third interval can be 0 or a circular arc with the same central angle.

[0246] In some embodiments, the four concentric circular areas are divided into upper half areas and lower half areas, and there is a fourth interval between the upper half areas and the lower half areas. For example, in Figure 8D , if the diameter of one dot-shaped code element is 1, the interval between the upper half areas and the lower half areas is 5.

[0247] The locator area is in the two-dimensional code, for example, in Figure 8D , three main locators 433 and one auxiliary locator 434 are included, the outer contours of the three main locators 433 and the auxiliary locator 434 are all circular, the centers of the main locators 433 are all in the penultimate concentric circular area in the periphery, and the diameter of one dot-shaped code element is 1, then the diameter of the three main locators 433 is 5.

[0248] Version five, the encoding area of the two-dimensional code includes 11 concentric circular areas.

[0249] As shown in Figure 8E , the image area 441 of the two-dimensional code in Figure 8E indicates the brand type (Harmony System, harmony OS) of the two-dimensional code. With the center point of the image area 441 as the center, the encoding area 442 includes 11 concentric circular areas, and dot-shaped code elements are uniformly arranged in each concentric circular area, and the distance between the centers of two adjacent dot-shaped code elements in each concentric circular area (or the length of the circular arc formed by the centers of every two adjacent dot-shaped code elements) is the same.

[0250] There is a first interval between the image area 441 and the encoding area 442, a second interval between each two adjacent concentric circular areas in the encoding area 442, and a third interval between two adjacent dot-shaped code elements in each concentric circular area. For example, in Figure 8EIn the image region 441, if the diameter of a dot-shaped symbol is 1, then the radius of the image region 441 is 10, and the interval between the image region 441 and the encoding region 442 is 1. That is, the first interval is 1 or the diameter of a dot-shaped symbol. The interval between any two adjacent concentric circular regions in the encoding region 442 is less than 1, that is, the second interval can be between 0 and 1. The interval between any two adjacent dot-shaped symbols in each concentric circular region can be 0, or it can be an arc with the same central angle. That is, the third interval can be 0, or it can be an arc with the same central angle.

[0251] In some embodiments, the 11 concentric circular regions are each divided into an upper region and a lower region, with a fourth interval between the upper and lower regions, for example, in... Figure 8E In this context, if the diameter of a dot-shaped symbol is 1, the interval between the upper and lower halves of the region is 5.

[0252] The locator area is within the QR code, for example in... Figure 8E It includes three main locators 443 and one auxiliary locator 444. The outer contours of the three main locators 443 and the auxiliary locator 444 are all circular. The center of the main locator 443 is in the second to last concentric circle region. The diameter of a dot-shaped code element is 1, so the diameter of the three main locators 443 is 5.

[0253] Version 6 includes 13 concentric circle areas in the QR code's encoding region.

[0254] like Figure 8F As shown, Figure 8F The image area 451 of the QR code indicates the brand type of the QR code (HarmonyOS). With the center point of the image area 451 as the center, the encoding area 452 includes 13 concentric circle areas. Each concentric circle area has evenly arranged dot-shaped code elements. The distance between the centers of two adjacent dot-shaped code elements in each concentric circle area (or the length of the arc formed by the centers of every two adjacent dot-shaped code elements) is the same.

[0255] There is a first interval between image region 451 and coding region 452, a second interval between every two adjacent concentric circle regions in coding region 452, and a third interval between two adjacent dot-shaped symbols in each concentric circle region. For example, in... Figure 8FIn the image region 451, if the diameter of a dot-shaped symbol is 1, then the radius of the image region 451 is 13, and the interval between the image region 451 and the encoding region 452 is 3. That is, the first interval is 3 or the diameter of three dot-shaped symbols. The interval between any two adjacent concentric circular regions in the encoding region 452 is less than 1, that is, the second interval can be between 0 and 1. The interval between any two adjacent dot-shaped symbols in each concentric circular region can be 0, or it can be an arc with the same central angle. That is, the third interval can be 0, or it can be an arc with the same central angle.

[0256] In some embodiments, the four concentric circular regions are each divided into an upper region and a lower region, with a fourth interval between the upper and lower regions, for example, in... Figure 8F In this context, if the diameter of a dot-shaped symbol is 1, the interval between the upper and lower halves of the region is 7.

[0257] The locator area is within the QR code, for example in... Figure 8F It includes three main locators 453 and one auxiliary locator 454. The outer contours of the three main locators 453 and the auxiliary locator 454 are all circular. The center of the main locator 453 is in the second to last concentric circle region. The diameter of a dot-shaped code element is 1, so the diameter of the three main locators 453 is 5.

[0258] Understandably, the more concentric circle regions and the more dot-shaped code elements there are, the larger the amount of data stored in that version. Not limited to the six versions mentioned above, the number of concentric circle regions and the number of dot-shaped code elements in each concentric circle region can have other configurations, and this application does not impose any restrictions on this.

[0259] S1052, Electronic device 100 can allocate the binary string S to each concentric circle area in the encoding area according to the image area, encoding area and locator position in the target version of the target QR code, and obtain the QR code information.

[0260] The electronic device 100 performs ring-splitting processing on the binary string according to the position of the image region, encoding region, and locator in the structure of the target version of the QR code to be generated. The binary string is then distributed into the dot-shaped code elements of each concentric circle region in the encoding region to obtain the QR code information.

[0261] Specifically, based on the number of concentric circle regions in the encoding area of ​​the QR code structure, and the information capacity of each concentric circle region (positively correlated with the number of dot-shaped code elements), the binary string can be split into substrings corresponding to each concentric circle region, and each substring can be assigned to the dot-shaped code elements in the corresponding concentric circle region for storage.

[0262] The two-dimensional code information includes information stored in each dot-shaped code element. For example, a dot-shaped code element in a first position stores first information, and a dot-shaped code element in a second position stores second information. The first position and the second position indicate the center coordinates and the radius information of the dot-shaped code element. For example, the first information can be 1 in a binary string, and the second information can be 0 in the binary string.

[0263] In some embodiments, the two-dimensional code information can further include a display form corresponding to each dot-shaped code element. For example, a dot-shaped code element storing first information is displayed in a first color, and a dot-shaped code element storing second information is displayed in a second color. For example, the first color can be black, and the second color can be white, transparent, or no color.

[0264] In some embodiments, the electronic device 100 further splits a substring corresponding to a concentric circular region into two substrings stored in the upper half region and the lower half region of the concentric circular region, respectively. The electronic device 100 can further split a substring corresponding to a concentric circular region into four substrings stored in the four quadrants of the concentric circular region, respectively.

[0265] The electronic device 100 fills the binary string into the dot-shaped code elements in the concentric circular regions of the target version of the two-dimensional code. The filling direction can be from the innermost concentric circular region to the outer concentric circular region, or from the outermost concentric circular region to the inner concentric circular region, or from left to right, from top to bottom, and the like. The embodiments of the present application do not limit the filling direction.

[0266] If a reserved region (for example, a region reserving format information or version information) or a functional module region (for example, a locator region, a calibration module region, or a time module region) is encountered, the code element at this position is not filled, and the filling continues until the next idle code element.

[0267] In S1053, the electronic device 100 selects a mask mode of the target two-dimensional code and adds mask information.

[0268] Masking refers to a strategy of changing the value of a code element in the encoding region of a two-dimensional code according to a specific rule. The purpose of using masking is to adjust the display effect of the code elements in the two-dimensional code (for example, to avoid large areas of blank or black blocks in the two-dimensional code, which affects code recognition), so as to facilitate the code reader to read information as easily as possible.

[0269] Masking patterns include, for example, masking all even-numbered concentric circle regions in a QR code; or, for example, masking some dot-shaped code elements within each concentric circle region of a QR code. Electronic device 100 uses masking patterns to overlay QR code information to adjust the layout of the QR code information, making the distribution of code elements in the QR code information more uniform, thereby making the generated QR code more aesthetically pleasing.

[0270] Specifically, masking QR code information can be achieved by performing an XOR operation between the binary string of the QR code information and the mask.

[0271] In some embodiments, the electronic device 100 fills the encoding area with QR code information that includes mask information. The electronic device 100 verifies whether the target version meets the capacity requirements of the QR code to be generated. If it does, version information is added.

[0272] S1054. The electronic device generates the target QR code.

[0273] In this embodiment, the electronic device 100 can encode the QR code encoding area by leaving unusable areas empty. After completing the encoding of the QR code encoding area and obtaining the QR code information, the electronic device 100, based on the QR code information, uses a drawing algorithm to draw the dot-shaped code elements storing the first information in the encoding area as the first color and the dot-shaped code elements storing the second information as the second color, thus completing the drawing of the encoding area. Furthermore, the electronic device 100 fills in the corresponding image area, locator area, and other areas in the target version to obtain a complete QR code image. The unusable areas include the image area, locator area, and blank areas in the encoding area of ​​the target version of the QR code (such as...). Figure 8A (A blank area with a 5-space interval between the upper and lower halves), etc.

[0274] In some embodiments, the electronic device 100 connects and draws dot-shaped code elements that meet preset conditions into arc-shaped code elements. The preset conditions include: if two or more consecutive adjacent dot-shaped code elements in a concentric circular region both store first information, the two or more adjacent dot-shaped code elements are connected and drawn into an arc-shaped code element, which is drawn in a first color. Optionally, the portion of the arc-shaped code element connecting the dot-shaped code elements is also filled with the first color, which can enhance the aesthetics of the QR code. Similarly, if two or more consecutive adjacent dot-shaped code elements in a concentric circular region both store second information, the two or more adjacent dot-shaped code elements are connected and drawn into an arc-shaped code element, which is drawn in a second color.

[0275] The following is an exemplary description of the QR code images generated from the six versions of QR codes mentioned above.

[0276] The target version is version one, the generated exemplary two-dimensional code is as shown in the following figure. Figure 3A Figure 3A The target version is version one, the generated exemplary two-dimensional code is as shown in the following figure.

[0277] The target version is version two, the generated exemplary two-dimensional code is as shown in the following figure. Figure 3B Figure 3B The target version is version two, the generated exemplary two-dimensional code is as shown in the following figure.

[0281] The target version is version six, the generated exemplary two-dimensional code is as shown in the following figure. Figure 3F Figure 3F The target version is version six, the generated exemplary two-dimensional code is as shown in the following figure. ​​​​​​

[0282] It can be understood that the two-dimensional code encoding method provided by the embodiment of the present application can be any combination of the above steps S101-S105. Alternatively, the two-dimensional code encoding method provided by the embodiment of the present application can be a two-dimensional code encoding method obtained by combining the steps associated with the above steps S101-S105, or can be a two-dimensional code encoding method obtained by combining the replacement schemes of any one of the above steps S101-S105. For example, the above step S102 can be replaced by the electronic device determining the character type of the N characters and determining the target encoding mode corresponding to each character type.

[0283] The embodiment of the present application provides a two-dimensional code encoding method. Through the method, the electronic device 100 can obtain a to-be-encoded text, and the to-be-encoded text can include N characters. The electronic device 100 determines one or more candidate encoding modes of each character in the N characters from X selectable encoding modes, selects a candidate encoding mode with the lowest number of encoding bits from the one or more candidate encoding modes as the target encoding mode of each character, and X is a positive number. The electronic device 100 divides the N characters into M character segments according to the target encoding mode of each character in the N characters, and determines the target encoding mode of the M character segments, each character segment in the M character segments including one or more characters. The electronic device 100 encodes the M character segments according to the target encoding mode of the M character segments, to obtain a binary string S. The electronic device 100 generates a target two-dimensional code corresponding to a version according to the length of the binary string S. In this way, the electronic device 100 can encode the to-be-encoded text into a binary string with a shorter length, thereby improving the data capacity of the two-dimensional code. Thus, the to-be-encoded text with a longer length can be encoded and a two-dimensional code can be generated.

[0284] For example, the string "0124FEAabcd" can be encoded into a 54-bit binary string "001100000001010100010011111111101010001100101010111101" according to the two-dimensional code encoding method provided in the embodiments of the present application. According to the encoding mode in the prior art, the electronic device 100 directly encodes the string "0124FEAabcd" as a whole, adopts the base128 encoding mode to encode, and obtains an 84-bit binary string. In the base128 encoding mode, the number of encoding bits is 7, and each of the 11 characters in "0124FEAabcd" is encoded into a 7-bit binary character, thereby obtaining a 77-bit binary string, and then 3 bits of mode indicator and 4 bits of length indication are added, and finally an 84-bit binary string is obtained. As can be seen, the binary string obtained by using the two-dimensional code encoding method provided in the embodiments of the present application is shorter. In this way, the electronic device can generate a two-dimensional code for a longer string.

[0285] Based on the two-dimensional code encoding method provided in the above embodiments, the embodiments of the present application further provide a two-dimensional code decoding method. The contents related to the foregoing embodiments are applicable to the present embodiment, and will not be repeated here. As shown in Figure 9 The two-dimensional code decoding method can specifically include the following steps:

[0286] S901, the electronic device 100 acquires a two-dimensional code to be decoded.

[0287] The electronic device 100 can acquire the two-dimensional code to be decoded through a camera, and the electronic device can also acquire the two-dimensional code to be decoded from the gallery of the electronic device. The electronic device 100 can also acquire the two-dimensional code to be decoded through another electronic device 100. That is, the other electronic device sends the two-dimensional code to be decoded to the electronic device 100. The embodiments of the present application do not limit the way in which the electronic device 100 acquires the two-dimensional code to be decoded.

[0288] The two-dimensional code to be decoded can be a QR code as shown in Figure 1 It can also be a two-dimensional code as shown in (a), (b) or (c) of Figure 2 or any version of the two-dimensional code shown in Figures 3A-3F The type of the two-dimensional code is not limited here.

[0289] The two-dimensional code to be decoded can be a two-dimensional code generated according to the steps S101-S105 described above.

[0290] In a possible implementation, before the electronic device 100 acquires the to-be-decoded two-dimensional code, the electronic device 100 acquires a first image containing the to-be-decoded two-dimensional code; and the electronic device 100 determines a region of the to-be-decoded two-dimensional code in the first image by using a locator (for example, the primary locator 403 and the auxiliary locator 404 shown in FIG. 8) in the to-be-decoded two-dimensional code. Figure 8A

[0291] Further, before the electronic device 100 determines the region of the to-be-decoded two-dimensional code in the first image, the electronic device 100 can perform preprocessing on the first image. The preprocessing can include one or more of grayscale processing, denoising processing, binarization processing, dilation processing, and corrosion processing. The specific processes of the grayscale processing, the denoising processing, the binarization processing, the dilation processing, and the corrosion processing can refer to the prior art, and will not be described here.

[0292] S902, the electronic device 100 acquires mode indication information from the to-be-decoded two-dimensional code.

[0293] The electronic device 100 can acquire the mode indication information from a coding region (for example, the coding region 402 shown in FIG. 8) of the to-be-decoded two-dimensional code. The mode indication information can be a binary string. The electronic device 100 can acquire the binary string used to identify the coding mode of the to-be-decoded two-dimensional code. Figure 8A

[0294] Optionally, the electronic device 100 can acquire version information of the to-be-decoded two-dimensional code, and determine the coding region in the to-be-decoded two-dimensional code based on the version information. Then, the electronic device 100 can acquire the mode indication information from the coding region.

[0295] S903, the electronic device 100 determines a coding mode from the mode indication information, and the electronic device 100 stores a mapping relationship table of the mode indication information and the coding mode.

[0296] The electronic device 100 can determine the coding mode of the to-be-decoded two-dimensional code according to the mode indication information, for example, the binary string used to indicate the coding mode. The electronic device 100 can store a mapping relationship table of the mode indication information and the coding mode. The mapping relationship table can be Table 1 in the foregoing, and can also be Table 11 in the foregoing. If the electronic device 100 acquires the mode indication information “0000”, the electronic device 100 can determine that the coding mode of the to-be-decoded two-dimensional code is the Terminator Mode. If the electronic device 100 acquires the mode indication information “0011”, the electronic device 100 can determine that the coding mode of the to-be-decoded two-dimensional code is the hybrid coding mode. The electronic device 100 can also determine the coding sub-mode of the to-be-decoded two-dimensional code from the mode indication information.

[0297] ​​Further, if the electronic device 100 determines that the mode indication information of the encoding sub-mode is included in the part of the characters in the encoding region of the to-be-decoded two-dimensional code, the electronic device 100 can determine the corresponding encoding sub-mode according to the mode indication information of the encoding sub-mode. For example, if the mode indication information is a binary string "000", the electronic device 100 can determine that the encoding sub-mode is a Base10 mode.

[0298] In a possible implementation, the electronic device 100 obtains multiple mode indication information, for example, multiple mode indicators, in the encoding region, and decodes the binary string according to the mode indication information corresponding to the binary string.

[0299] S904, the electronic device 100 decodes the to-be-decoded two-dimensional code according to the determined encoding mode, to obtain the encoding information in the two-dimensional code.

[0300] The electronic device 100 decodes the to-be-decoded two-dimensional code according to the determined encoding mode. If the electronic device 100 obtains the compression indication information from the to-be-decoded two-dimensional code, the electronic device 100 can decompress the to-be-decoded two-dimensional code according to the compression indication information. If the electronic device 100 obtains the encryption indication information, the electronic device 100 can also decrypt the to-be-decoded two-dimensional code according to the encryption indication information. Finally, the electronic device 100 can obtain the encoding information in the to-be-decoded two-dimensional code, for example, "abcd", for example, "I love my family" and the like. In the embodiment of the present application, the encoding information in the two-dimensional code can be referred to as first information.

[0301] In a possible implementation, the electronic device 100 can determine, from the encoding region, how many binary bytes are included in the encoding region, the length of each binary byte, and the encoding mode. The electronic device 100 can encode each byte according to the encoding length corresponding to the byte. For example, the electronic device 100 can determine that the mode indication information is "0011" from the to-be-decoded two-dimensional code. Then the encoding mode of the to-be-decoded two-dimensional code is a hybrid encoding mode. If the byte length in the encoding information is 3, it indicates that the to-be-decoded two-dimensional code is encoded by 3 binary strings. The electronic device can obtain the encoding sub-mode indicators (for example, "001", indicating that the encoding mode is a Base10 mode) and the length indication (for example, "100" indicating that the number of original characters encoded into the binary string is 4) of the 3 binary strings from the encoding region, and finally obtain the specific results of the 3 binary strings, for example, "000001010100". The binary string "000001010100" can be decoded according to the encoding sub-mode to obtain the two-dimensional code encoding information, that is, the numerical character "0124".

[0302] In a possible implementation, the to-be-decoded two-dimensional code contains an encoding area, and the electronic device determines the mode indication information from the to-be-decoded two-dimensional code, specifically including: the electronic device acquires the mode indication information from a symbol in the encoding area in which the mode indication information is stored. In this way, the electronic device can acquire the mode indication information.

[0303] In a possible implementation, before the electronic device acquires the mode indication information from the symbol in the encoding area in which the mode indication information is stored, the method further includes: the electronic device acquires version information of the to-be-decoded two-dimensional code, and determines a target version of the to-be-decoded two-dimensional code based on the version information; the target version indicates coordinate information of each storage location in the encoding area of the to-be-decoded two-dimensional code; and the electronic device determines binary values corresponding to storage locations occupied by each symbol in the plurality of symbols in the encoding area of the to-be-decoded two-dimensional code according to the coordinate information of each storage location. In this way, the electronic device can accurately determine the binary values corresponding to each symbol in the encoding area.

[0304] Optionally, the binary data can be 0 or 1.

[0305] In a possible implementation, the electronic device can determine the version information of the to-be-decoded two-dimensional code according to distances between any two locators in the to-be-decoded two-dimensional code. Different version information corresponds to different distances between any two locators in the two-dimensional code.

[0306] In a possible implementation, the electronic device decodes the to-be-decoded two-dimensional code according to the encoding mode to obtain the first information, including: the electronic device decodes the binary values corresponding to the storage locations occupied by each symbol in the plurality of symbols in the encoding area of the to-be-decoded two-dimensional code according to the encoding mode to obtain the first information. Different encoding modes correspond to different encoding bit numbers, so that the electronic device can accurately decode the binary values corresponding to the bit numbers to obtain the first information according to the encoding mode.

[0307] In a possible implementation, the electronic device acquires the mode indication information from the to-be-decoded two-dimensional code, including: the electronic device acquires one mode indication information from the to-be-decoded two-dimensional code, and one or more sub-mode indication information contained in the mode indication information.

[0308] The electronic device determines the encoding mode of the to-be-decoded two-dimensional code from the mode indication information, including: the electronic device determines the encoding mode of the to-be-decoded two-dimensional code from the mode indication information, and determines one or more encoding sub-modes of the to-be-decoded two-dimensional code from the one or more sub-mode indication information.

[0309] The electronic device decodes the binary values corresponding to the storage positions occupied by each of the plurality of code elements in the encoding region of the to-be-decoded two-dimensional code according to the encoding mode to obtain the first information, including: the electronic device decodes the binary values corresponding to the storage positions occupied by each of the plurality of code elements in the encoding region of the to-be-decoded two-dimensional code according to one or more encoding sub-modes to obtain the first information.

[0310] The first information can be encoded into the to-be-decoded two-dimensional code by a plurality of encoding sub-modes in one encoding mode. In this way, the electronic device can gradually subdivide decoding, and accurately decode the first information from the to-be-decoded two-dimensional code.

[0311] In a possible implementation, the one or more encoding sub-modes include a first encoding sub-mode and a second encoding sub-mode, and the encoding region includes a first encoding region and a second encoding region; the electronic device decodes the binary values corresponding to the storage positions occupied by each of the plurality of code elements in the encoding region of the to-be-decoded two-dimensional code according to the one or more encoding sub-modes to obtain the first information, including: the electronic device decodes the binary values corresponding to the storage positions occupied by each of the plurality of code elements in the first encoding region according to the first encoding sub-mode, and decodes the binary values corresponding to the storage positions occupied by each of the plurality of code elements in the second encoding region according to the second encoding sub-mode to obtain the first information. In this way, the electronic device can gradually subdivide decoding, and accurately decode the first information from the to-be-decoded two-dimensional code.

[0312] In a possible implementation, the mode indication information and the one or more sub-mode indication information are binary characters with a fixed number of bits.

[0313] In a possible implementation, the electronic device determines the encoding mode of the to-be-decoded two-dimensional code from the mode indication information, and the electronic device stores one or more mapping relationship tables, and the mapping relationship tables include the mode indication information and the encoding mode corresponding to the mode indication information, including: the electronic device queries the encoding mode corresponding to the mode indication information and the encoding bit number of the encoding mode in the mapping relationship table.

[0314] In a possible implementation, the electronic device determines the encoding mode of the to-be-decoded two-dimensional code from the mode indication information, and the electronic device stores one or more mapping relationship tables, and the mapping relationship tables include the mode indication information and the encoding mode corresponding to the mode indication information, and specifically including: the electronic device queries the encoding mode corresponding to the mode indication information and the encoding sub-mode corresponding to each of the one or more encoding sub-mode indication information in the mapping relationship table.
