Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than those herein described, and those skilled in the art will readily appreciate that the present application may be similarly embodied without departing from the spirit or essential characteristics thereof, and therefore the present application is not limited to the specific embodiments disclosed below.

The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The manner of description used in the present application and in the appended claims is for example: "a", "a" and "a" etc. are not limited in number or order, but are used to distinguish the same type of information from each other.

Before describing a data generating method provided by the application, a detailed description is made of the conceptual background of the application so as to facilitate the subsequent understanding of the application.

The Bar Code provides great convenience for life, for example, when shopping, commodity information can be obtained by scanning the Bar Code on the commodity through the scanning equipment, so that the working efficiency of settlement work is greatly improved. With the continuous improvement of society, the continuous improvement of living standard of people, the continuous innovation of technology and technology, the mode of storing data information by the bar code gradually highlights the shortage of storage capacity and a plurality of defects of limited data identification direction and storage direction, and then the two-dimensional code (Quick Response Code) replaces the bar code and fills all aspects in life.

The two-dimensional code has more storage than the bar code, and is not limited by the scanning direction. Two-dimensional codes are also called as two-dimensional Bar codes (QR codes), which are more common coding modes on mobile devices in recent years, and can store more information and represent more data types than traditional Bar codes (Bar codes).

The two-dimensional code is a graph which is distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is alternately black and white and records data symbol information; the concept of a binary bit stream of 0 and 1 which form the internal logic foundation of a computer is utilized in code programming, a plurality of geometric shapes corresponding to binary are used for representing literal numerical information, and the information is read by terminal equipment to realize automatic information processing.

Along with the continuous development of application business, the complexity and the data volume of data are improved, and the data expansion cannot be performed on the basis of the conventional universal black-and-white two-dimensional code composed of black-and-white colors, namely, under the environment with complex data, the conventional universal black-and-white two-dimensional code can only take the expanded data and the original data as a whole to generate the universal black-and-white two-dimensional code comprising a large amount of complex data to realize the bearing of the data, however, even if the universal black-and-white two-dimensional code is generated, the recognition difficulty of the universal black-and-white two-dimensional code is correspondingly increased, and accordingly, better requirements are also put forward on recognition equipment.

Under the application background, the application provides a data generation method, which can generate a target two-dimensional code capable of carrying data of a general two-dimensional code and additional data on the basis of the existing general two-dimensional code, in other words, the target two-dimensional code not only comprises the data borne by the general two-dimensional code, but also comprises data except the data borne by the general two-dimensional code. Next, a detailed description will be given of a specific implementation procedure of the data generation method provided by the present application.

Referring to fig. 1, fig. 1 is a flowchart of an embodiment of a data generating method according to the present application.

The generating method embodiment comprises the following steps:

step S101: encoding the obtained original information and the adding information required to be added into the original information to generate a first encoded data stream corresponding to the original information and a second encoded data stream corresponding to the adding information;

the purpose of the step S101 is to determine the original information and the added information added to the original information, that is, the information included in the original information and other information to be carried, so as to expand the capacity of the original two-dimensional code carrying information, and the expansion part is the added information part.

In this embodiment, the original information may also be understood as information based on a two-dimensional code to be generated, for example: the website link information, picture information, text information and the like can be evolutionary data, and do not only refer to information traced back to the root cause.

It can be understood that, based on the application scenario with a large amount of complex data, the original information is a large amount of complex data, in order to facilitate reducing the generation and recognition difficulty of the two-dimensional code, the step S101 provides two implementation manners as follows:

mode one, including:

step S101-11: dividing the acquired original information to obtain dividing information at least comprising two parts, namely first part dividing information and second part dividing information, wherein the second part dividing information is added information for adding to the first part dividing information.

Step S101-12: the first part of split information and the second part of split information after splitting are coded, and a first coded data stream corresponding to the first part of split information and the second coded data stream corresponding to the second part of split information are generated.

The division of the original information in step S101-11 may be determined according to the complexity of the specific information of the original information or according to the requirement of generating the two-dimensional code, and the manner of this embodiment is merely illustrative for convenience of explanation, and is not limited to the above.

Typically, the added information may be an unnecessary information part, such as: some of the original information is auxiliary descriptive information.

Mode two, including:

step S101-21: acquiring original information of an original two-dimensional code to be generated; step S101-22: determining extension information with association relation with the original information;

step S101-23: and acquiring the adding information required to be added into the original information according to the determined extension information.

In the second mode of the present embodiment, the original information may be understood as basic information, the added information may be extended information based on the basic information, and the extended information may be a supplementary description of the original information, where a certain association relationship exists between the two.

Based on the above, the added information in this embodiment may be a part of the original information or a part of the non-original information, and in short, the added information may be information that needs to be added to the original two-dimensional code according to the requirement.

The above description is given of the original information and the added information in two ways only, and it is understood that the source of the original information and the added information is not limited to the above.

After the original information and the additional information are obtained, the original information is encoded to generate a first encoded data stream, and the additional information is also encoded to generate a second encoded data stream, which are described below, wherein the encoding of the original information belongs to the prior art, so the following description is focused on the encoding process of the additional information.

First, the encoding process of the original information is schematically described, namely: encoding the obtained original information to generate a first encoded data stream, including:

encoding the acquired original information to obtain a first encoded value;

the first encoded value is converted into a binary encoded data stream.

Next, the process of encoding the obtained added information to generate a second encoded data stream is described, including:

Step S102-1: encoding the obtained added information to obtain a second encoded value;

step S102-2: the second encoded value is converted into a binary encoded data stream.

Step S102-1 is to encode the added information, and a Unicode encoding mode can be adopted to obtain a Unicode value, wherein Unicode (world Unicode) is a set of character encoding formulated by the world Unicode Union, and comprises most of language words and expression words in the world. Unicode encoding provides a set of base unit codes, each base unit being assigned a unique Code Point. A text element is composed of one or more basic units. Of course, other coding schemes may be used. After the encoded values are obtained, the encoded values need to be converted into a binary encoded data stream.

Step S103: generating an original two-dimensional code according to the first coded data stream, and generating corresponding target color data according to the second coded data stream.

The specific implementation of step S103 is also described from two angles, namely, for the original information and the added information, respectively.

Firstly, based on the above steps 101-102, it can be known that the obtained original information is encoded to generate a first encoded value, the first encoded value is converted into a binary encoded data stream, and then an original two-dimensional code is generated according to the binary encoded data stream corresponding to the first encoded value, and the generation process of the original two-dimensional code can be obtained by adopting the existing generation method, and the outline of the original two-dimensional code is described below.

In this embodiment, the obtaining of the original two-dimensional code may be performed by using the existing process of generating the black-and-white two-dimensional code, that is, determining the original information needed to generate the original two-dimensional code, and obtaining the original two-dimensional code generated according to the original information, specifically please refer to fig. 2, where fig. 2 is a schematic structural diagram of the general black-and-white two-dimensional code. The original two-dimensional code may also be referred to as a universal black-and-white two-dimensional code in this embodiment, and there are 40 sizes, which may be named Version. There is a linear relationship between size and Version: version 1 is a 21 x 21 matrix and Version 2 is a 25 x 25 matrix, with 4 increases in Size for each Version added, so the linear relationship between Size and Version is: the maximum value of Version is 40, so the size maximum is a matrix of (40-1) x 4+21=177, i.e. 177x 177.

Each part of the original two-dimensional code has the function of the original two-dimensional code, and can be basically divided into three parts of positioning, functional data and data content, namely the structure of the original two-dimensional code comprises a positioning area, a functional data area and a data content area.

A blank area 20;

the location area includes:

positioning pattern 21 (Position Detection Pattern): the method is used for marking the size of the two-dimensional code rectangle, and the position and the direction of one two-dimensional code rectangle can be marked and determined by using three positioning patterns, i.e. three positioning pattern areas are shown as the upper left, the lower left and the upper right in fig. 2.

Positioning the pattern divider 22 (Separators for Position Detection Patterns): the positioning pattern is distinguished from other areas by white borders.

Timing pattern 23 (Timing Patterns): for positioning, if the two-dimensional code is oversized, the two-dimensional code is easy to distort during scanning, and the time sequence pattern is used for preventing the distortion during scanning.

Alignment pattern 24 (Alignment Patterns): only Version 2 and above would be required.

Functional data:

format information 25 (Format Information): storing the formatted data in all sizes;

version information 26 (Version Information): for Version 7 or above, two 3×6 regions need to be reserved to store partial Version information;

the data content is as follows: the remainder storing data content

Data Code 27 (Data Code) and error correction Code 27 (Error Correction Code).

Then, the data is encoded to generate corresponding original two-dimensional codes. The form of data encoding may include: numerical code (numerical Mode), character code (Alphanumeric Mode), byte code (Byte Mode), japanese code (Kanji Mode), other codes. After data encoding, the original two-dimensional code structure can be drawn, and finally the pattern of the original two-dimensional code is obtained, and redundant description is omitted here.

In the step S103, the generating corresponding target color data according to the second encoded data stream may include:

step S103-1: dividing the binary coded data stream corresponding to the second coded data stream according to the bit number of the color value, and generating target color data corresponding to the binary coded data stream.

The step S103-1 may specifically be divided according to the number of bits of the RGB color values, that is, three bits, and it can be understood that, because the original two-dimensional code mainly adopts black and white, that is: RGB color values are 0,0 (black) and 1,1 (white), and thus, black and white are thrown out, and division of the binary coded data stream may result in RGB (1, 0) red for the corresponding target color data, RGB (0, 1, 0) green, RGB (0, 1) blue, RGB (1, 0) yellow, RGB (1, 0, 1) bright purple, RGB (0, 1) cyan, whereby corresponding color information can be obtained from RGB color values.

It will be appreciated that when dividing the binary coded stream by three-bit color values, if it is up to the last less than three bits, the missing bits may be complemented to keep the division still three bits, and the complemented bits may be zero. Of course, in dividing a binary coded stream, if the divided three bits are (1, 1) or (0, 0), it should be noted that there is a corresponding protocol to convert the binary stream into a corresponding bin at the time of encoding and decoding. The corresponding binary is a scalable protocol, and in this embodiment six color binary streams can be used, so the conversion is based on planing off white and black, so the case of division (1, 1) or (0, 0) does not occur. However, according to further development of the imaging technology, in other embodiments, the present application is turned into more color to increase the data capacity, and thus is not limited to the above 6 colors. Namely: the 8-ary conversion is performed to the 6 (8-2) ary. More color expansion is that the third power (three channel) system of the single channel tone scale k (2 in this embodiment) is converted to the k-th power of 3-2 system.

Step S104: and replacing original pixels in the original two-dimensional code data area with pixels corresponding to the target color data to generate a target two-dimensional code compatible with the original two-dimensional code.

The specific implementation process of step S104 may include:

and replacing the black pixel value in the original two-dimensional code data area with the pixel value corresponding to the target color data to generate a target two-dimensional code compatible with the original two-dimensional code, wherein as shown in fig. 3, fig. 3 is an image schematic diagram of the target two-dimensional code compatible with the original two-dimensional code.

In this embodiment, in order to ensure accuracy of identifying the color in the target two-dimensional code under different environmental conditions, or to improve the fault tolerance of the identification. The embodiment may further include:

and marking color verification data for verifying the target color data in the target two-dimensional code in a positioning area of the original two-dimensional code. As shown in fig. 3, the upper left corner and the lower left corner in fig. 3 are the positioning areas, and in this embodiment, the positioning area in the upper left corner is taken as an example, and the color verification data is marked in the positioning area. Likewise, the color verification data may be color data excluding the original color data in the original two-dimensional code, which is selected to be determined as the color verification data, and in this embodiment, the color verification data includes 6 color verification data, that is: RGB (1, 0) red, RGB (0, 1, 0) green, RGB (0, 1) blue, RGB (1, 0) yellow, RGB (1, 0, 1) bright purple, RGB (0, 1) cyan. After the color verification data is determined, the black pixel data in the positioning area is replaced by the six color verification data. For the original two-dimensional code, the positioning area and even the data area are displayed in black and white colors, so that the original pixel data can be in black and white colors, and in the embodiment, the positioning area is mainly displayed in black pixels, so that the color verification data can be marked to replace the black pixel value of the positioning area with the six color verification values. The color verification data are marked in the positioning area, so that the accuracy of information can be guaranteed, and the space of the two-dimensional code can be saved.

When the target two-dimensional code is identified, the color part in the data area can be compared with the color check value of the positioning area, so that the accuracy of color identification is ensured.

In order to ensure accuracy of data identification, in this embodiment, the method may further include:

aiming at the obtained added information required to be added into the original two-dimensional code, generating information verification data for verifying the added information; the generation of the information verification data can adopt a hash algorithm to generate a hash value representing the added information, namely the identifier, so that the added information is verified when the added information is analyzed, and the accuracy of the added information is ensured.

And adding the information verification data into a positioning area of the target two-dimensional code. In this embodiment, the information verification data is added to the positioning area, so that the two-dimensional code space can be saved.

That is, it is determined whether the identified added information is correct by the information verification data. And similarly, encoding the information verification data to obtain verification color data for verifying the added information, and replacing black pixels in the target two-dimensional code positioning area with color pixels corresponding to the verification color data.

It should be noted that, when the color verification data is located at the upper left of the target two-dimensional code, the information verification data may be a location area at the lower left or a location area at the upper right.

Any one of the color verification data and the information verification data in the embodiment can be generated after the original two-dimensional code is generated, or can be generated while the target two-dimensional code compatible with the original two-dimensional code is generated, or can be generated after the original pixels in the original two-dimensional code data area are replaced by the pixels corresponding to the target color data, and finally the target two-dimensional code is generated according to the color verification data, the information verification data and the target color data in the data area.

According to the data generation method provided by the application, the finally generated target two-dimensional code can be compatible with the information of the conventional black Bai Erwei code (original two-dimensional code) and can also comprise added information, and under the condition that the original information is complex, the target two-dimensional code can be encoded, so that the data storage capacity can be expanded, and the recognition error rate is reduced.

Since the parsing method of the original two-dimensional code corresponds to the generating method of the original two-dimensional code, the step S501 may directly use a decoding method corresponding to the encoding method used when the original two-dimensional code is generated to decode the original two-dimensional code, so as to obtain the original information stored in the original two-dimensional code, and for the target two-dimensional code, the image information includes a black-white display area and a color display area, and the parsing method of the original information stored in the original two-dimensional code may include:

Only the analysis of the target color data of the data area in the target two-dimensional code is described, because the color area of the target two-dimensional code image comprises 6 RGB values, namely: RGB (1, 0) red, RGB (0, 1, 0) green, RGB (0, 1) blue, RGB (1, 0) yellow, RGB (1, 0, 1) bright purple, RGB (0, 1) cyan, and further, the partial analysis of the scanned color region can obtain the corresponding RGB values, namely binary data stream.

Step S502: decoding the first code value and the second code value to obtain original information in the original two-dimensional code and added information added into the original two-dimensional code data area;

the decoding process in step S502 decodes by adopting a decoding mode corresponding to the encoding mode, so as to obtain the added information added to the original two-dimensional code data area.

To ensure the correctness of the obtained added information, the method further comprises:

Otherwise, if the information verification data are different, the generated information verification data are wrong, the problem of the added information is described, and further analysis of the added information in the target two-dimensional code is failed.

Step S503: and determining the original information and the added information as data content compatible with the target two-dimensional code of the original two-dimensional code.
