Description

Pattern identification code processing method and device

technical field

The invention relates to the technical field of graphic identification codes, in particular to a method and device for processing graphic identification codes.

Background technique

With the development of technology, the use of QR codes is becoming more and more widespread. We can often see QR codes on TV screens, printed matter, web pages, and commodities. Users can scan the QR codes with mobile phones and other devices, and then get corresponding information.

Users can also convert information into QR codes through QR code software and share them with others. Because information such as URLs, texts, images, and sounds can be converted into two-dimensional codes and shared with others, users often use two-dimensional codes. When the user needs to make the electronic device generate multiple two-dimensional codes in a short period of time, the user cannot distinguish the multiple generated two-dimensional codes, which leads to errors in sharing the two-dimensional codes. Of course, if the user needs to use a certain QR code generated in the electronic device before, the user needs to search it from the historical QR code, because the user also cannot distinguish it, so the search is difficult. In this case, users may need to convert the QR code into original information to know whether it is what they are looking for, which is very tedious and wastes a lot of time.

Of course, graphic identification codes such as one-dimensional codes, colorful two-dimensional codes, and multi-dimensional codes also have the above-mentioned problems.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 1, a method for processing a graphic identification code provided by an embodiment of the present invention may include:

S100. Obtain shared information and a graphic identification code corresponding to the shared information;

Specifically, the shared information may be a network link, text, picture, audio, etc. Step S100 may first obtain the shared information, and then encode the shared information to convert it into a graphic identification code. In order to improve information security, the shared information can be encrypted first, and then converted into a graphic identification code. In step S100, the graphic identification code can also be obtained first, and then the graphic identification code can be decoded to obtain the shared information. When the shared information carried by the graphic identification code is encrypted, the shared information obtained after decoding can be decrypted.

Wherein, the graphic identification code may be a two-dimensional code, a one-dimensional code, a multi-dimensional code, and the like.

In step S100, obtaining the graphic identification code corresponding to the shared information may include:

Encrypting the shared information according to a preset encryption algorithm to generate first encrypted data;

Adding an encryption identifier to the first encrypted data to generate second encrypted data;

The second encrypted data is encoded to generate a graphic identification code to be marked.

It should be noted that the addition of the encryption mark can enable the device that decodes the graphic identification code to know whether the information in the graphic identification code is encrypted, and which encryption algorithm is used for encryption. In this way, the device for decoding the graphic identification code can successfully use the corresponding decryption algorithm to decrypt, so as to obtain the shared information.

S200. Obtain an identification code to be added according to the shared information;

Wherein, when the shared information is a network link, the identification code may be the website logo or website name corresponding to the network link. It can be understood that both the website logo and the website name can serve as an identifier for the graphic identification code, and can help users learn the shared information corresponding to the graphic identification code. When the shared information is text, some characters in the text can be selected as identification codes, such as the first two words in the text. When the shared information is a picture, the thumbnail of the picture may be used as the identifier of the identification code. Of course, since the shared information has many different types such as audio, pictures, text, and network links, the type of shared information can also be used as an identification code to identify it, which can also play a role in identifying it. For example, when the shared information is an audio file, Identify "audio" as the identifier.

Therefore, step S200 may include:

determine the type of information shared;

When it is determined that the shared information is a network link, accessing a webpage corresponding to the network link;

obtaining a website identifier corresponding to the network link from the webpage;

The website ID is used as the identification code ID to be added.

Alternatively, step S200 may include:

determine the type of information shared;

When determining that the shared information is text, extract character groups from the text according to preset extraction rules;

The extracted character group is identified as an identification code to be added.

Wherein, the preset extraction rule may be: extracting a certain number of characters at the forefront from the beginning of the text according to the sequence of the characters, or extracting the characters with the highest frequency of occurrence.

S300. Generate a background image that can cover the graphic identification code and the identification code;

Since the pictures are generally set to be rectangular, the size of the background picture will be described below by taking all the pictures as rectangular pictures as an example.

Assuming that the length and width of the graphic identification code are L1 and D1 respectively, and the length and width of the identification code logo are L2 and D2 respectively, then according to the different placement positions of the graphic identification code and the identification code logo, the size of the background image that can cover them can be Dimensions shown in Figures 2 to 4. Specifically, as shown in FIG. 2, when the pattern identification code and the identification code mark are placed up and down, the length and width of the background picture (that is, the dotted frame) are at least L1 and D3 respectively, and D3=D1+D2. As shown in FIG. 3 , when the pattern identification code and the identification code mark are placed left and right, the length and width of the background picture (that is, the dotted frame) are at least L3 and D1 respectively, and L3=L1+L2. As shown in Figure 4, when the pattern identification code and the identification code mark are placed obliquely, the length and width of the background picture (that is, the dotted frame) are at least L3 and D3 respectively, L3=L1+L2, D3=D1+D2 .

Certainly, the three placement positions shown in FIGS. 2 to 4 are only partial placement positions of the present invention. The background pictures in Figures 2 to 4 are single white pictures, and can also be set as other color pictures or multi-color pictures in practical applications. Preferably, the background image should not interfere with the identification of the graphic identification code, nor should it interfere with the user's identification of the identification code. In FIG. 2 to FIG. 4 , in order to facilitate the understanding of the background image, a dotted frame is used. In practical applications, there may not be a dotted frame.

It can be seen that the pattern identification code and the identification code identification in the embodiment of the present invention do not overlap with each other.

S400. Synthesize both the identification code mark and the pattern recognition code into the background image, and make the recognition code mark and the pattern recognition code non-overlapping each other, and generate a pattern recognition code image with the recognition code mark .

The synthesized images can refer to the images in Fig. 2 to Fig. 4 .

A pattern identification code processing method provided by an embodiment of the present invention can automatically obtain the identification code to be added according to the shared information, and synthesize the pattern identification code and the identification code into the background image after the background image is generated. Graphical identification codes and identification code marks can be overlaid, so that the pattern identification codes and identification code marks can not overlap each other during synthesis. Therefore, the present invention can automatically generate a graphic identification code with a logo, the distinguishability of the graphic identification code is improved, and the user can easily identify it. Further, since the pattern identification code and the identification code logo do not overlap each other in the picture synthesized by the present invention, the pattern identification code will not be blocked, which ensures the recognition accuracy of the pattern identification code when it is recognized.

As shown in FIG. 5, in another method for processing a graphic identification code provided in an embodiment of the present invention, step S400 may include:

S401. Convert the graphic identification code into a first two-dimensional data matrix, convert the identification code into a second two-dimensional data matrix, and convert the background image into a third two-dimensional data matrix, wherein the The third two-dimensional data matrix includes a first sub-matrix and a second sub-matrix that do not overlap each other, the number of rows and columns of the first sub-matrix is the same as the number of rows and columns of the first two-dimensional data matrix, and the second sub-matrix The number of rows and columns of the matrix is the same as the number of rows and columns of the second two-dimensional data matrix;

S402. According to the preset data replacement rules, replace the data in the first sub-matrix with the data in the first two-dimensional data matrix, and replace the data in the second sub-matrix with the second The data in the two-dimensional data matrix generates the fourth two-dimensional data matrix;

It can be seen that step S401 and step S402 use the method of matrix replacement to synthesize pictures. It is understandable that, for a computer, a plane picture should be transformed into a two-dimensional data matrix, and then the computer can recognize and operate it. The values in each matrix represent the color information of the corresponding position in the picture, so that the values in the entire matrix form a complete picture. After modifying the value of the corresponding position in the matrix, the color of the picture position corresponding to the value will also change. Correspondingly, modifying a sub-matrix composed of multiple values in the matrix will cause a certain area in the picture corresponding to the sub-matrix to change.

S403. Convert the fourth two-dimensional data matrix into a graphic identification code image with an identification code mark.

It should be noted that those skilled in the art can also use known image synthesis methods to perform image synthesis, which is not limited in the present invention.
