[0043] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0044] The technical solution of the present application is applicable to various scenarios of coding identification. Specifically, the technical solution of the present application is applicable to scanning the coding pattern carried by the object to be identified through the mobile terminal in the scenario of coding identification, so as to obtain, interact, and disseminate the information of the object to be identified. In practical applications, the coding pattern can be a QR code, etc., and the object to be identified can be multimedia materials such as pictures, videos, paper documents, or other specific items such as cups, boxes, and equipment that can be printed and fixed with coding patterns. Exemplarily, the coding pattern on the shoe box is scanned by the mobile terminal to obtain the coding information indicated by the coding pattern, and the information corresponding to the shoe box (shoes) is read from the storage device according to the coding information, so that the user can perform anti-counterfeiting identification according to the read information to avoid buying counterfeit and shoddy products. It can be understood that when identifying the coding pattern, it is not limited to the mobile terminal, and the user can identify the coding pattern through any coding pattern recognition device with the function of scanning and identifying the coding pattern.

[0045] In order to facilitate understanding of the technical solution in this application, the dot matrix module in this application is first introduced. Figure 1As shown, the dot matrix module of the present application is a tiny dot matrix module of a specific size graphic. The coding pattern is the dot matrix module in this scheme. Take the dot matrix module whose vector size can be 5mm*5mm as an example. The dot matrix module consists of 36 graphical logos in 6 rows and 6 columns, the three graphical logos at the head are the starting position logos, the three graphical logos at the tail are the ending position logos, and the remaining multiple graphical logos arranged in sequence are multiple coding logos. Among them, the starting position logo is used to indicate the starting position of the multiple coding logos in the dot matrix module; the ending position logo is used to indicate the ending position of the multiple coding logos in the dot matrix module; the graphical logo has a corresponding shape feature, and the shape feature is used to indicate the specific graphic of the graphical logo. For example, if the shape feature of a graphical logo is a circle, it indicates that the graphical logo is a circle, and if the shape feature of a graphical logo is a square, it indicates that the graphical logo is a square. It can be understood that the number of starting position logos and ending position logos can be changed according to user needs.

[0046] In this application, if Figure 1 As shown in the figure, each coding mark corresponds to a binary value, for example, a circle represents 0 and a square represents 1. The graphic marks on the dot matrix module follow the order from left to right and from top to bottom. Excluding the 3 starting position marks at the head and the 3 ending position marks at the tail, we can get a 30-digit binary coding data string. Therefore, the capacity of this coding method can reach 2 30 , that is 1073741824 times.

[0047] In the present application, the color of each graphical mark in the dot matrix module has the same RGB value, and the center distances between adjacent graphical marks are the same. At the same time, each coded mark corresponds to a binary value.

[0048] In one embodiment, Figure 2 As shown, the present application proposes an encoding method, the method comprising:

[0049] Step 201: Acquire an object to be encoded and encoding information set for the object to be encoded, wherein the encoding information includes a plurality of encoding values ​​arranged in sequence.

[0050] Coding is the process of converting information from one form or format to another. In this solution, for multimedia data or specific items, a coding pattern corresponding to the multimedia data or specific items is generated, that is, a dot matrix module, so that users can read the information corresponding to the multimedia data or specific items by scanning the coding pattern.

[0051] The object to be encoded refers to multimedia data or specific items for printing and fixing coding patterns. Coding information refers to a data string including multiple sequentially arranged coding values, through which specific information data can be read from a storage device. In practical applications, coding information can be a binary coded data string in computer language, for example, 10011111000111.

[0052] Step 202: determine the first graphical identifier corresponding to each coding value according to the order of the coding values ​​in the coding information, so as to obtain the first graphical identifiers arranged in order corresponding to the coding information.

[0053] The first graphical identifier is as follows: Figure 1 The coding mark in the dot matrix module. The coding value refers to the binary value in computer language, which can be 0 or 1.

[0054] Among them, after obtaining the coding information, the coding identifier corresponding to each binary numerical value arranged in sequence in the coding information can be determined in sequence according to the preset coding value and graphic identifier shape feature correspondence table, that is, the first graphic identifier arranged in sequence is determined.

[0055] In a specific embodiment, a binary value corresponds to a graphical identifier. Figure 3 As shown, if the graphical symbol corresponding to the binary value 1 is a square and the graphical symbol corresponding to the binary value 0 is a circle, then the multiple first graphical symbols arranged in order corresponding to the coding information 0111001 are circle, square, square, square, circle, circle, square.

[0056] In a specific embodiment, a binary value may correspond to multiple graphical identifiers. Figure 4 As shown, if the graphic identifier corresponding to the binary value 1 is a square and a triangle, and the graphic identifier corresponding to the binary value 0 is a circle, then the multiple first graphic identifiers arranged in sequence corresponding to the coded information 0110 are circle, square, square, circle, or circle, triangle, triangle, circle, or circle, square, triangle, circle, or circle, triangle, square, circle. It can be understood that when a binary value corresponds to multiple graphic identifiers, any one of the multiple graphic identifiers is randomly obtained and determined as the first graphic identifier corresponding to the binary value.

[0057] By setting each dot in the dot matrix module as a graphical mark and corresponding each graphical mark to a binary coding value, not only the information capacity of the coded information can be greatly increased, but also the security and confidentiality of the dot matrix module can be greatly improved.

[0058] Step 203: Generate a dot matrix module according to the first graphical logos arranged in sequence.

[0059] Among them, after determining the first graphical identifier of the sequential arrangement according to the sequentially arranged coding value, the preset starting position identifier and the ending position identifier can be obtained; then the starting position identifier is placed at the head of the first graphical identifier of the sequential arrangement, and the ending position identifier is placed at the tail of the first graphical identifier of the sequential arrangement; finally, according to the identifier string composed of the starting position identifier, the first graphical identifier, and the ending position identifier, an m*m dot matrix module is generated in the order from top to bottom and from left to right.

[0060] The initial position is marked as Figure 1 The initial position mark in the dot matrix module and the end position mark are Figure 1 The initial position mark in the dot matrix module. It should be emphasized that in order to avoid recognition errors during code recognition, the starting position mark and the ending position mark are graphical marks different from the first graphical mark, that is, the initial position shape of the initial position mark and the ending position shape of the ending position mark are different from the graphics of the first graphical mark.

[0061] Step 204: after setting the color feature for the dot matrix module, superimpose the dot matrix module onto the object to be encoded to obtain a target object carrying the encoding information.

[0062] The color of each graphical mark in the dot matrix module has the same RGB value, so that the coding pattern recognition device can accurately recognize the dot matrix module from the object carrying the coding pattern.

[0063] In a specific embodiment, in order to prevent the coding pattern from affecting the aesthetics of the object to be coded, the concealment of the coding pattern can be improved and the incompatibility between the coding pattern and the object to be coded can be reduced. Specifically, the RGB value of the graphical identifier in the dot matrix module can be set to an RGB value close to the object to be coded. Setting a color feature for the dot matrix module is to set an RGB value for the dot matrix module.

[0064] In a specific embodiment, Figure 5 As shown, taking multimedia data as an example, in order to reduce the probability of missing dot matrix modules with coding information due to range cutting of the multimedia data, the present application will copy five identical dot matrix modules, divide the multimedia data into four areas equally, and superimpose the five dot matrix modules on the center points of the four areas and the center point of the data respectively.

[0065] The present application proposes a coding method, the method comprising: obtaining an object to be coded and coding information set for the object to be coded, the coding information comprising sequentially arranged coding values; determining the first graphical identifier corresponding to each coding value according to the order of the coding values ​​in the coding information, so as to obtain the first graphical identifier arranged in sequence corresponding to the coding information; generating a dot matrix module according to the first graphical identifier arranged in sequence; after setting a color feature for the dot matrix module, superimposing the dot matrix module on the object to be coded, so as to obtain a target object carrying the coding information. The present application can not only greatly improve the information capacity of the coding information, but also greatly improve the security and confidentiality of the dot matrix module by setting each point in the dot matrix module as a graphical identifier and corresponding each graphical identifier to a binary coding value. By setting a color feature for the dot matrix module, the dot matrix module can be accurately identified, and the coding pattern can be prevented from affecting the aesthetics of the object to be coded.

[0066] In one embodiment, Figure 6 As shown, the present application proposes a coding reading method for reading the coding information indicated by the dot matrix module obtained by the coding method proposed in the present application. The method comprises:

[0067] Step 601, obtaining an object to be identified that carries coding information, wherein the object to be identified includes a dot matrix module for indicating coding information, wherein the dot matrix module includes first graphical identifiers arranged in sequence, and one first graphical identifier corresponds to one coding value.

[0068] The object to be identified refers to multimedia data or specific items with printed and fixed coding patterns, and the coding pattern includes a dot matrix module for indicating coding information.

[0069] Among them, the dot matrix module can be as follows Figure 1 The first graphical identifier is as shown in FIG. Figure 1 Multiple coding marks in the dot matrix module.

[0070] Among them, the graphical logo has a shape feature corresponding thereto, and the shape feature is used to indicate the specific graphic of the graphical logo. A first graphical logo corresponds to a coding value, which means that a first graphical logo corresponds to a graphic, and a graphic corresponds to a coding value. It can be understood that the first graphical logo includes at least one first graphical logo. In practical applications, multiple first graphics may also correspond to one coding value at the same time. For example, a square may correspond to a coding value of 1, and a circle may correspond to a coding value of 0; or a square and a triangle may correspond to a coding value of 1 at the same time, and a circle and a hexagon may correspond to a coding value of 0 at the same time.

[0071] Step 602: Identify the dot matrix module from the object to be identified according to the color feature of the object to be identified.

[0072] The color feature of the object to be identified refers to the RGB value of the object to be identified.

[0073] The color of each graphical mark in the dot matrix module has the same RGB value. The coded pattern recognition device obtains the RGB value of the object to be recognized; then obtains a preset range of RGB values; if the RGB value of a certain area of ​​the object to be recognized is within the preset range of RGB values, it means that the area is a dot matrix module area.

[0074] Step 603: Determine the code value corresponding to each first graphical mark in the dot matrix module according to the shape characteristics of each first graphical mark.

[0075] The shape feature of the first graphical identifier refers to the graphic of the first graphical identifier. Since one first graphical identifier corresponds to one graphic, and one graphic corresponds to one coding value, after identifying the dot matrix module, the shape feature of the first graphical identifier in the dot matrix module can be identified, thereby determining the graphic of the first graphical identifier, and determining the coding value corresponding to the first graphical identifier according to the graphic of the first graphical identifier.

[0076] In a specific embodiment, the dot matrix module also includes a starting position identifier and an ending position identifier, the starting position identifier includes at least one second graphic identifier different from the first graphic identifier, which is used to indicate the starting position of the first graphic identifiers arranged in sequence in the dot matrix module, and the ending position identifier includes at least one third graphic identifier different from the first graphic identifier, which is used to indicate the ending position of the first graphic identifiers arranged in sequence in the dot matrix module; before determining the coding value corresponding to each first graphic identifier in the dot matrix module according to the shape characteristics of each first graphic identifier in the dot matrix module, it also includes: identifying the starting position identifier and the ending position identifier according to the shape characteristics of each graphic identifier in the dot matrix module; determining the starting position and the ending position of the arrangement of the first graphic identifiers arranged in sequence according to the starting position identifier and the ending position identifier.

[0077] The starting position marker can be Figure 1 The starting position mark in the dot matrix module shown is located at the head of the dot matrix module and includes at least one second graphical mark different from the first graphical mark. Specifically, the second graphical mark can be as follows: Figure 1The water drop graphic shown; the starting position identifier is used to indicate the starting position of the first graphical identifier arranged in sequence in the dot matrix module. Specifically, the first graphical identifier in the first graphical identifier arranged in sequence is the graphical identifier after the starting position identifier, that is, the starting position of the first graphical identifier arrangement.

[0078] The end position marker can be: Figure 1 The end position mark in the dot matrix module shown is located at the end of the dot matrix module and includes at least one third graphical mark different from the first graphical mark. Specifically, the third graphical mark can be as follows: Figure 1 The water drop graphic shown. It can be understood that the third graphical mark and the second graphical mark can also be different graphics; the end position mark is used to indicate the end position of the first graphical marks arranged in sequence in the dot matrix module. Specifically, the last graphical mark in the first graphical marks arranged in sequence is the previous graphical mark of the end position mark, that is, the end position of the first graphical mark arrangement.

[0079] The number of first graphic logos can be well controlled through the starting position identifier and the ending position identifier, so that even two dot matrix modules with the same arrangement and number of graphic logos can include different numbers of first graphic logos, thereby increasing the difficulty of information cracking and greatly improving the data security of the dot matrix module.

[0080] In a specific embodiment, the second graphic logo and the third graphic logo are both non-centrally symmetric graphic logos; before determining the coding values ​​corresponding to the first graphic logos in the dot matrix module according to the shape features of the first graphic logos, it also includes: obtaining the inclination angle of any graphic logo in the second graphic logo and / or the third graphic logo relative to the horizontal direction; rotating the dot matrix module by an angle equal to the inclination angle so that the dot matrix module is horizontal relative to the horizontal direction, to obtain a rotated dot matrix module; and identifying the shape features of the first graphic logos in the rotated dot matrix module.

[0081] Among them, the position of any one of the second graphical logo and / or the third graphical logo is determined, and the circumscribed rectangle of the graphical logo and the bottom side of the circumscribed rectangle are determined, and then the inclination angle between the bottom side of the circumscribed rectangle and the horizontal direction is determined, and the inclination angle between the bottom side of the circumscribed rectangle and the horizontal direction is used as the inclination angle of the dot matrix module relative to the horizontal direction; after determining the inclination angle of the dot matrix module relative to the horizontal direction, the dot matrix module can be rotated by an angle equal to the inclination angle to make the graphical logo in the dot matrix module horizontal relative to the horizontal direction. For example, taking the second graphical logo and the third graphical logo as ellipses as an example, Figure 7aAs shown, the circumscribed rectangle of the graphical mark and the bottom side of the circumscribed rectangle are determined, and the inclination angle α between the bottom side of the circumscribed rectangle and the horizontal direction is used as the inclination angle of the dot matrix module relative to the horizontal direction. After the dot matrix module is rotated clockwise by the angle α, the rotated dot matrix module can be obtained, as shown in FIG. Figure 7b shown.

[0082] Among them, after obtaining the rotated dot matrix module, a pre-stored graphic logo shape feature table can be obtained, and the graphic logo shape feature table stores the correspondence between the graphic logo and the graphic logo shape feature; traverse the graphic logo shape feature table, and find the shape feature matching each first graphic logo from the graphic logo shape feature table.

[0083] In this embodiment, by determining whether the graphical mark is tilted, it is possible to ensure that the dot matrix module has rotation invariance, thereby making the code reading more accurate.

[0084] In a specific embodiment, the identification distances between adjacent graphic logos in the dot matrix module are equal; before determining the coding values ​​corresponding to each first graphic logo in the dot matrix module based on the shape features of each first graphic logo in the dot matrix module, it also includes: determining the position of each first graphic logo in the dot matrix module based on a preset identification distance; and identifying the shape features of each first graphic logo after the position is determined.

[0085] The identification distance between adjacent graphical identifications refers to the distance between the center points of adjacent graphical identifications.

[0086] In this embodiment, since the identification distances between adjacent graphic logos in the dot matrix module are equal, after determining the starting position and the ending position of the sequentially arranged first graphic logos, the specific position of each first graphic logo can be determined according to the distance between adjacent first graphic logos, thereby improving the accuracy of determining the position of the graphic logo, and performing shape recognition on each first graphic logo after the position is determined, thereby improving the accuracy of code reading.

[0087] In a specific embodiment, determining the coding value corresponding to each first graphic logo according to the shape characteristics of each first graphic logo in the dot matrix module includes: binarizing each first graphic logo according to the shape characteristics of each first graphic logo in the dot matrix module to obtain the coding value corresponding to each first graphic logo.

[0088] The binary assignment refers to determining the binary value corresponding to each first graphical logo according to a preset correspondence table between the coding value and the shape feature of the graphical logo.

[0089] By assigning a binary value to each first graphical identifier, the graphical identifier can be converted into a set of binary coded data strings, thereby improving the simplicity of coded data storage and reducing memory usage.

[0090] Step 604: Determine the coding information of the object to be identified according to the coding values ​​corresponding to the first graphical identifiers.

[0091] After the coding value corresponding to the first graphical mark is determined, the coding information of the object to be identified can be determined, and the information data of the object to be identified can be read from the storage device according to the coding information.

[0092] In a specific embodiment, determining the coding information of the object to be identified based on the coding values ​​corresponding to the first graphical identifiers includes: forming a binary coding data string corresponding to the dot matrix module based on the coding values ​​corresponding to the first graphical identifiers; and determining the coding information of the object to be identified based on the binary coding data string.

[0093] Among them, since the first graphical identification is arranged in sequence, after determining the code value corresponding to the first graphical identification, the binary code data string corresponding to the dot matrix module can be determined, and the binary code data string is the code information of the object to be identified.

[0094] The present application proposes a code reading method, which includes: obtaining an object to be identified that carries code information, wherein the object to be identified includes a dot matrix module for indicating the code information, wherein the dot matrix module includes first graphic identifiers arranged in sequence, and each first graphic identifier corresponds to a code value; identifying the dot matrix module from the object to be identified according to the color characteristics of the object to be identified; determining the code values ​​corresponding to each first graphic identifier in the dot matrix module according to the shape characteristics of each first graphic identifier; and determining the code information of the object to be identified according to the code values ​​corresponding to each first graphic identifier. By setting the first graphical logos arranged in sequence, and one first graphical logo corresponds to one coding value, the dot matrix module can have the characteristics of large coding capacity and not easy to imitate, and the micro-dot matrix structure has the characteristics of high concealment; by obtaining the object to be identified that carries the coding information, the dot matrix module can be identified; through the color characteristics of the object to be identified, the dot matrix module can be quickly and accurately identified from the object to be identified; because one first graphical logo corresponds to one coding value, the coding value corresponding to each first graphical logo can be accurately and efficiently determined through the shape characteristics of each first graphical logo, thereby accurately determining the coding information of the object to be identified. The coding reading method proposed in the present application can accurately identify the dot matrix module set in the present application, and can greatly improve the anti-counterfeiting performance and security performance of the coding information of the object to be identified.
