The following is a preferred embodiment of a method for generating a text two-dimensional code, which can solve the above technical problems and is provided in the present invention, and please refer to fig. 1 for illustration:
the preferred embodiment of the method for generating the literal two-dimensional code provided by the invention comprises the following steps:
step S11: making the text two-dimension code content into a square two-dimension code, extracting a square two-dimension code element of the square two-dimension code, and dividing the square two-dimension code element into square two-dimension code element blocks;
step S12: extracting key contents in the text two-dimensional code contents;

step S15: and associating the text two-dimensional code content with the text two-dimensional code pattern to generate the text two-dimensional code.
According to the invention, the square two-dimensional code pattern is converted into the character two-dimensional code pattern, so that a user can obtain partial information of the two-dimensional code content only by looking at the code without scanning the code, the two-dimensional code forms are diversified, the readability of the two-dimensional code pattern is improved, and the problems that the two-dimensional code form is single and the readability of the square two-dimensional code pattern is poor due to the fact that the two-dimensional code pattern is composed of small black blocks in the prior art are solved.
The traditional two-dimensional code is a square two-dimensional code, which is composed of a square two-dimensional code pattern and square two-dimensional code contents. Visually, the square two-dimensional code pattern is composed of two-dimensional code elements, and the character two-dimensional code pattern is composed of characters. The character two-dimensional code is the same as the square two-dimensional code, and also has the content of the character two-dimensional code, namely the content displayed after being identified by a code scanning machine, in daily life, compared with a small black block in a square two-dimensional code element, the characters can convey information more intuitively.
Referring to step S11, the text two-dimensional code content is made into a square two-dimensional code, and a square two-dimensional code element of the square two-dimensional code is extracted, and the square two-dimensional code element is divided into square two-dimensional code element blocks. In order to generate the two-dimensional character code, a two-dimensional character code pattern is also required, and therefore, in step S12, key content in the two-dimensional character code content is extracted. The key content may include keywords, and key pictures. In addition, in order to make the user more easily understand the type of the text two-dimensional code content, step S12 may further include classifying the text two-dimensional code content, and extracting a category to which the text two-dimensional code content belongs as key content, so as to more clearly display the text two-dimensional code content.
For example, the content displayed by a text two-dimensional code pattern is a zoo, and a user viewing the text two-dimensional code may think that the text two-dimensional code may be an introduction to the zoo, ticketing information of the zoo, map information of the zoo, or the like. However, if a 'map' is added to the character two-dimensional code as key content, a user viewing the character two-dimensional code can accurately judge that the character two-dimensional code is map information of the zoo, so that the accuracy of directly displaying information by the character two-dimensional code is further improved.
It should be noted that the square two-dimensional code elements have irregular shapes and cannot be replaced subsequently, and therefore the square two-dimensional code elements need to be divided into square two-dimensional code element blocks with regular shapes, which is convenient for subsequent replacement. The square two-dimensional code element block here includes a square block, a rectangular block, and an irregular block in a preset database, such as a1 × 1 square block, a2 × 2 square block, a2 × 4 rectangular block, a1 × 2 rectangular block, a1 × 5 rectangular block, a1 × 3 rectangular block, and the like.
The specific division mode may be: dividing the content of the character two-dimension code into three sections of visual works, auditory works and audio-visual combined works, and extracting keywords and keywords according to the following modes:
when the content of the character two-dimensional code is visual works such as characters, pictures, websites, links and the like, extracting the name and the author of the character as keywords and keywords, and extracting the character and the word with the highest frequency of occurrence as the keywords and the keywords if the author does not have the name;
specifically, when the content of the two-dimensional code is a text, the content includes texts such as novel novels, reports, contracts, posts, loans, notes, applications, lectures, and history notes, which are commonly and commonly used in daily life, and different contents are extracted for different texts. When the text content is classified and identified to be the novel, the name and the author of the extracted novel are used as keywords, if the text content is the novel written by Zhang III, namely you me He, Zhang III and the novel are used as keywords;
when the text content is identified to be the report by classification, the main content of the report is extracted, and the reporter is taken as a keyword, if the text content is the Chinese situation of Zhang three reports, the Chinese situation, Zhang three reports and the report are extracted as the keyword;
when the text content is classified and identified to be a contract, the name of the extracted contract and both signing parties are used as keywords, if the text content is a 'house renting contract' signed by Zhang III and Li IV, the 'house contract', 'Zhang III' and 'Li IV' are extracted as the keywords, and the 'contract' without text type is difficult to misunderstand for people, so the 'contract' does not need to be extracted as the keywords;
when the text content is recognized as an invitation card in a classified manner, inviters and invitations for extracting the invitation card are used as key words, if the text content is the invitation card which is sent by Zhang three-Job congratulations and invites friends to participate, the keywords such as "Joies", "Zhang three" and "invitation card" are extracted, the meaning of the "invitation card" can be transmitted through a text two-dimensional code, and the holding time and the holding place can be extracted as the key words in consideration of more convenience for Zhang three friends to acquire more information;
when the text content is recognized as the loans in a classified manner, the borrower and the lender who extract the loans are used as keywords, the loans are a genre which can be used as names, and the repeat can not be extracted any more, if the text content is a loan which has three sides and four sides with ten thousand of money borrowed, three sides, four sides and the loans are extracted as the keywords, and the loans are a problem which can be used as names, so that the repeat phenomenon can be generated if the loans are extracted as the keywords;
when the word content is identified by classification as a beginner, the name of the extracted beginner and the sender of the beginner are used as keywords, the 'beginner' is also a corpus which can be used as the name, extraction is still not needed, and if the word content is 'beginner' sent by Zhang III, the 'beginner' and the 'Zhang III' are extracted as the keywords;
when the text content is recognized as an application book in a classified manner, the name of the application book and an application author are extracted as keywords, if the text content is an admission application book submitted by Zusanqi, the 'admission application book' and the 'Zusanqi' are extracted as the keywords, and the 'application book' is the name capable of being used as a genre and is not required to be extracted as the keywords;
when the character content is classified and recognized to be the lecture draft, the name, the author and the speaker of the lecture draft are extracted to be used as key words, when the author and the speaker of the lecture draft are the same person, multiple extraction is not needed, if the character content is the lecture draft of a mobile phone release meeting with three pages, and if the speaker is a Liqu, the mobile phone release meeting, the Zusanli and the Liqu are extracted to be used as key words;
when the classified and recognized character content is history transmission, the name and the author of the history transmission are extracted as keywords, the history transmission is a character body which can be used as the name, and the extraction is still not needed, if the character content is a school history written by Zhang III, the school history and the Zhang III are extracted as keywords;
it should be noted that the above-mentioned genre types do not represent all genres, and all the note data types such as notes, etiquette types such as posters, enlightenment types such as article finding initiatives, application types such as admission applications, economic documents such as contracts, propaganda types such as lectures, news types such as reports, history and the like are extracted according to the respective extraction methods of the different genre types mentioned in the present specification. For ancient poetry and music titles, based on the commonness of the poetry and the novel, the poetry and music titles are created by tasks and have names, so that the extraction mode is carried out according to the extraction mode of the novel.
When the content in the character two-dimensional code is a picture, the picture comprises common photos, pictures, picture sets and maps in daily life, and different contents are extracted aiming at different picture types.
When the picture content is classified and recognized to be a picture, a photographer, the picture content such as 'people', 'scenes', 'buildings' and the like are extracted as key words, if the character two-dimensional code content is a green mountain shot by Zhang three, the 'Zhang three' and the 'green mountain' are extracted as the key words because the 'green mountain' belongs to a specific subclass of 'scenes', and if the picture content is a Paris iron tower shot by Li four, the 'Li four' and the 'Paris iron tower' are extracted as the key words.
When the picture content is classified and identified to be a picture, the author and the name of the picture are extracted to be used as key words, if the character two-dimensional code content is a clear river map drawn by Zhang III, the 'Zhang III' and the 'clear river map' are extracted to be used as the key words, and meanwhile, a thumbnail of the 'clear river map' can also be extracted to be used as the picture.
When the classified and recognized picture content is a painting set, the painting techniques such as 'sketch', 'oil painting', 'ink painting' and the like are extracted as key words, if all the paintings in the displayed painting set are created by the same person, the authors can also be extracted as key words, and if the two-dimensional code content of the characters is a sketch painting set of Zhang III, 'Zhang III' and 'sketch' are extracted as key words.
When the classified and identified picture content is a map, the map content is extracted as a keyword, and the map is usually an anonymous author, so that the map content is only extracted as the keyword unless the map author is signed, and if the text two-dimensional code content is a treasure buried map, a 'treasure map' is extracted as the keyword.
The two-dimension code content is set to be a website, which is a common phenomenon in daily life, when the classified and identified content is the website, the name of the website is extracted to be used as a keyword, and if the written two-dimension code content is the Shenzhen government official website, the Shenzhen government is extracted to be used as the keyword.
In addition, the link is also a common operation in daily life as the two-dimensional code content, when the classified and identified content is the link, the type of the link is extracted as a keyword, and if the character two-dimensional code content is a cash register, a cash register is extracted as a keyword.
When the content of the literal two-dimensional code is auditory works such as broadcasting, phase sound, songs and the like or audio-visual combined works such as movies, TV plays, short films and the like, the name and the author of the literal two-dimensional code are extracted as keywords and keywords, and the type of the literal two-dimensional code is extracted as keywords and keywords if the author does not have the name;
when the classified and identified content is broadcast, the broadcast content is extracted as a keyword, if the text two-dimensional code content is news simulcast, the news simulcast is extracted as the keyword, meanwhile, in order to avoid confusion between the broadcast and the television, the broadcast is also extracted as the keyword, and as the broadcast is not listened to intentionally by listening to the broadcast daily, the broadcaster is not extracted as the keyword.
When the classified and recognized contents are voices, names and performers of the contents are extracted as keywords, if the contents of the character two-dimensional codes are voices of Zhang III and Li IV (Kaihu), the contents of 'Kaihu', 'Zhang III' and 'Li IV' are extracted as keywords, and in order to avoid unnecessary misunderstanding, people mistakenly think that Zhang III, Li IV will be learned and other contents, the 'voices' are also extracted as keywords.
When the classified and identified content is a song, the name and the author of the song are extracted as keywords, and if the content of the character two-dimensional code is song "put school", the content of "put school" and "zhang san" are extracted as keywords. Because the frequency of the songs and the phase sounds enjoyed by people in daily life is different, and the frequency of the songs in daily life is usually much higher than that of the sounds, so that the songs are mostly known, and the songs do not need to be extracted as keywords.
When the classified and identified content is a movie, the name, director and director of the movie are extracted as key words, if the text two-dimensional code content is Zhang three-led movie work, which is mastered by Li four, the keywords of work, Li four and work are extracted, usually, the movie has a propaganda poster, and the propaganda poster can be extracted as a key picture. After the propaganda poster is provided, the content of the character two-dimensional code can be clear at a glance without extracting 'movie' as a key word.
When the classified and identified content is a television series, the name and the lead actor of the classified and identified content are extracted as keywords, if the text two-dimensional code content is the television series 'life' with the lead actor of Zhang III, the 'life' and the 'Zhang III' are extracted as the keywords, and the 'television series' can also be extracted as the keywords.
When the classified and recognized content is a short piece, the name and the author of the short piece are extracted as keywords, if the text two-dimensional code content is a short piece 'study' created by Zhang III, the 'study' and the 'Zhang III' are extracted as keywords, and the 'short piece' can also be extracted as keywords.
When the keywords and the keywords cannot be extracted from the text two-dimension code content, the user sets the keywords and the keywords by himself. For example, in the case of a text two-dimensional code content, a section of text with an anonymous author and no title exists, or a voice chat where the text two-dimensional code content is located, or a picture where the content is difficult to identify, and the like, the text two-dimensional code content cannot extract keywords and keywords, and the user needs to set the keywords and the keywords by himself to improve the readability of the text two-dimensional code, and the keywords cannot be extracted and are set by the user.
In step S13, since the code scanner cannot recognize the characters, a database needs to be preset, and the preset database is used to binarize the keywords, and key pictures extracted or input in step S12 and convert the binarized keywords, and key pictures into keyword blocks, and key picture blocks that can be recognized by the code scanner, such as 1 × 1 keyword blocks, 2 × 2 keyword blocks, 2 × 4 keyword blocks, 1 × 2 keywords, 3 × 3 key picture blocks, etc., and the keyword blocks, and key picture blocks also form a character two-dimensional code pattern, so that the code scanner can recognize the character two-dimensional code pattern.
Referring to fig. 4, when the text two-dimensional code pattern includes a picture block, the text two-dimensional code pattern can attract people to read, and the content of the picture is intuitive, so that the readability of the text two-dimensional code is improved.
The invention aims to convert a square two-dimensional code into a character two-dimensional code, if characters with fewer strokes are encountered, or the characters are amplified and then appear to be fewer strokes in a certain area, so that the character two-dimensional code cannot be recognized by a machine or is recognized by mistake after being generated, the step S13 of the invention can also comprise the steps of detecting the proportion of character parts and blank parts in a keyword block, setting background colors of the characters when the proportion of the character parts is less than alpha, and outputting the keyword block with the background colors and the keyword block. Therefore, the readability of the character two-dimensional code pattern is improved, and meanwhile the fault tolerance of the character two-dimensional code is also improved.
As shown in fig. 7, for example, when the content of the text two-dimensional code is a fast playing song "ten years", the "fast playing" and "ten years" are extracted as keywords, and exactly 2 × 4 squares in the square two-dimensional code pattern can set the keywords "ten years" as a large one font to be highlighted, however, after the replacement of the keyword block "ten years" is completed, the text portion in the located square is less, and it is obvious that the text portion in the located square of "ten" is less in proportion, which may cause a situation that the recognition is difficult, so that the background color is set for the key block "ten years", so as to avoid a situation that the text two-dimensional code pattern cannot be recognized by a machine.
It should be noted that, in order to prevent the background color from covering the text pattern, which makes the text pattern difficult to be recognized by naked eyes and affects the readability of the text two-dimensional code pattern, the background color herein adopts a light color as the background color, such as gray, sky blue, lemon yellow, and the like.
Considering that if a1 × 5 rectangular block is divided in step S11, but a1 × 5 key content block is not obtained in step S13, which may cause inconvenience in the subsequent step S14, in step S11, a filtering and classifying operation may be performed to further divide the square block and the rectangular block for replacing the square two-dimensional code element. The specific division can be performed as follows:
calculating rectangular blocks of 3 XN and NX 3(8 is more than N and more than 3) in the square two-dimensional code element block as class A blocks; the square blocks with the size of 3 multiplied by 3 and larger than 3 multiplied by 3 are counted as class B blocks; 2 XN and NX 2(8 > N > 2) rectangular blocks are counted as class C blocks; 2 multiplied by 2 square blocks are counted as class D blocks; the rectangle blocks of 1 XN and 1 X2 (8 > N > 1) are counted as E class blocks; the 1 × 1 square blocks count as class-six blocks. If no keyword exists, the screening is not carried out. And screening various blocks in sequence according to the sequence of A, B, C, D, E and F. After the screening is completed, splitting the blocks according to the following sequence:
splitting the class A block into a combination of (B + C) blocks or a combination of (B + E) blocks;
splitting the C-type blocks of which the N is 5 and the N is 7 into a combination of (butyl + pentyl) type blocks;
when the number of the keyword characters is less than N in the E-type blocks, the E-type blocks are divided into a combination of a plurality of small E-type blocks, and the number of the keyword characters can be equal to N in the small E-type blocks;
then, referring to step S14, the two-dimensional code element of the block is replaced by the key content, i.e., the key block, and the key picture block after binarization, so as to obtain a two-dimensional code pattern, i.e., a character two-dimensional code pattern, which can be recognized by both eyes and machines.
For example, when the keywords "zoo", "map", "Shenzhen" are extracted, if the keywords are not divided in the above manner, it may occur that a square two-dimensional code element block composed of five small black blocks is replaced by one keyword block "map" and one keyword block "Shenzhen", while a square two-dimensional code element block composed of a single small black block is left without corresponding content replacement. Therefore, in order to avoid the occurrence of the above situation, the readability of the text two-dimensional code pattern can be ensured to be improved, the five small black blocks form the square two-dimensional code element block and are divided into the square two-dimensional code element block formed by the three small black blocks and the square two-dimensional code element block formed by the two small black blocks, namely, a1 × 5 rectangular block is divided into a combination of a1 × 2 rectangular block and a1 × 3 rectangular block, and then the keyword block "zoo" and the keyword block "map" can be used for replacing the square two-dimensional code element block formed by the three small black blocks and the square two-dimensional code element block formed by the two small black blocks, so that the situation that the square two-dimensional code element block formed by the single small black block does not have corresponding contents to replace after the replacement is finished is avoided.
In order to realize diversification of the character two-dimensional code patterns, the characters can be replaced in the following modes after screening and classification are completed: because the diversification degree of the image is higher than that of characters, the square block is replaced by the image block; the rectangular blocks are replaced by keyword blocks and keyword blocks; wherein the key content block can be highlighted by changing the size of the key content block based on user settings.
Referring to fig. 4, the present invention provides an alternative way to replace the square blocks with the picture blocks, such as replacing 3 × 3 square blocks with zoo maps, to highlight the content that the user wants to express.
Considering that the square two-dimensional code element has high scattering degree, square blocks or rectangular blocks with large quantity are difficult to form, and the error correction performance based on the two-dimensional code is based on, the step S11 in the invention also includes filling irregular blocks according to the patterns of the square two-dimensional code element block and the key content block based on the user setting, so that the irregular blocks are changed into the square blocks or the rectangular blocks, generating the filled square two-dimensional code element, enabling the data code word sequence of the two-dimensional code not to be changed, and replacing the filled square two-dimensional code element block with the key content block to generate the character two-dimensional code pattern. Therefore, more square blocks and rectangular blocks can be formed, and the readability of the character two-dimensional code pattern is further improved. The following is a specific embodiment provided by the present invention:
according to the pattern of the square two-dimensional code element, the keyword block and the keyword block, when the number of keywords is 3 and no 2 x 6 rectangular block exists in the square two-dimensional code element block, the square two-dimensional code element block is partially filled to generate the 2 x 6 rectangular block, so that a square block and a rectangular block based on user requirements are generated by analogy, the filled square two-dimensional code element block is generated, the data code word sequence of the two-dimensional code is not changed, the filled square two-dimensional code element is replaced by the keyword block and the keyword block, and a character two-dimensional code pattern is generated.
Please refer to fig. 5, the zoo staff wants to have a large font of "zoo" or "map" in the text two-dimensional code pattern, so that the text two-dimensional code pattern can show the "zoo" or "map" more prominently, however, the square two-dimensional code element block has a2 × 6 rectangular block inside, so that a part of the square two-dimensional code element block can be filled with the rectangular block, so that the rectangular block with 2 × 6 is generated, and the subsequent replacement is completed.
In addition, step S12 in the present invention may further include setting a weight for the extracted nouns based on the frequency or the user setting; step S14 further includes performing replacement according to the weight of the key content during replacement, and the key content block corresponding to the key content with high weight has high frequency of occurrence after the replacement is completed. Therefore, the content which the user wants to show can be displayed in the character two-dimensional code pattern more accurately, the condition of avoiding heavy things and reducing weight is avoided, and the readability of the character two-dimensional code pattern is further improved. For example, when the content of the two-dimensional code is a balloon of dualbow singing lie four by zhang san, the extracted keywords will be zhang san, lie four and dualbow balloon. Generally speaking, most of the original sings are heard, so that the singer pays attention to the singing, and because the songs are turned and are not consistent with the original singing songs heard under the common condition, the original singing of the songs can be more similar to the representation or the turning of the songs can be more expected to be represented according to the requirements of the user, and the weight of the original singing and the turning weight in the keywords can be set by the user. When the user tends to embody the singer, the weight of the keyword "zhang san" may be set high, and the weight of the keyword "li san" may be set low. Therefore, the text two-dimensional code pattern can more clearly show the content which the user wants to show.
For how to realize that the occurrence frequency of the key content block corresponding to the key content with high weight is high after the replacement is completed, the following measures can be taken: during replacement, the replacement proportion of the keyword block of Zhang three to Liqu is set to be 2: 1, namely in the replacement process, after the replacement of two keyword blocks of Zhang III is finished, replacing one keyword block of Liquan.
Considering that daily two-dimensional codes appear in various scenes and a circle of people can scan one two-dimensional code around the two-dimensional code, the method also comprises the steps of partitioning the character two-dimensional code pattern, rotationally converting part of key content blocks in each area, and after the conversion is finished, in the plane of the character two-dimensional code pattern, having the key content blocks with the character orientation pointing to the nearby frame in each partition. Obtaining a character two-dimensional code pattern after the conversion is finished;
in other words, in the text two-dimensional code pattern plane, the text in each partition has the text orientation. The text is oriented in the direction pointed by the top of the text. The directions of the characters in the key content blocks in the partitions are directed to the nearby border, and the characters are preferably directed vertically, so that the situation that the two-dimensional code patterns of the characters are disordered and difficult to identify by naked eyes due to too much directing is avoided, and the readability of the two-dimensional codes of the characters is reduced.
Specifically, the character two-dimensional code pattern is partitioned, and orthogonal decomposition is carried out along the centroid of the character two-dimensional code pattern into a left upper area, a right upper area, a left lower area and a right lower area;
after the replacement is finished, the key content blocks in the upper left fragment area are randomly divided into an upper left group and an upper left group, and the ratio of the number of the key content blocks in the upper left group to the number of the key content blocks in the upper left group is beta;
dividing the upper right slice area into an upper right group and an upper right group; dividing the left lower slice area into a left lower group and a left lower group; dividing the right lower area into a right lower group and a right lower group; the words in the key content blocks in each group are rotated so that the words in the top left group are oriented in the same direction as the words in the top right group, the words in the top left group are oriented in opposite directions to the words in the bottom left group, the words in the top left group are oriented in opposite directions to the words in the top right group, the words in the top left group are oriented in the same direction as the words in the bottom left group, and the words in the top left group are oriented in opposite directions to the words in the bottom right group and the words in the top left group are oriented in opposite directions to the words in the bottom.
Wherein beta is a user setting value and can be set randomly based on a use scene, so that the character two-dimensional code pattern can more flexibly show the face with the highest readability.
Please refer to fig. 6, the present invention further provides a specific transformation method: dividing the character two-dimensional code pattern into regions, and performing orthogonal decomposition along the center of the character two-dimensional code pattern into an upper left region A, an upper right region B, a lower left region C and a lower right region D;
after the replacement is completed, the key content blocks in the upper left slice a are randomly divided into an upper left group a1 and an upper left group a2, and the ratio of the number of key content blocks in the upper left group a1 to the number of key content blocks in the upper left group a2 is 1;
the upper right panel B is divided into an upper right group B1 and an upper right group B2; dividing the left lower panel zone C into a left lower group C1 and a left lower group C2; dividing the lower right panel D into a lower right group D1 and a lower right group D2; the text in the key content blocks in each group is rotated so that the text in the top left group a1 is oriented the same as the text in the top right group B1, the top left group a1 is oriented opposite to the text in the bottom left group C1, the top left group a2 is oriented opposite to the text in the top right group B2, the top left group a2 is oriented the same as the text in the bottom left group C2, the top left group a1 is oriented opposite to the text in the bottom right group D1 and the top left group a2 is oriented opposite to the text in the bottom right group D2.
In the mode, beta is 1, and the key word blocks in the upper left group A2 and the characters in the key word blocks are rotated by 90 degrees anticlockwise around the character center; the key word blocks in the upper right two groups B2 and the characters in the key word blocks are rotated by 90 degrees clockwise around the character center; rotating key word blocks in the left lower group C2 and characters in the key word blocks by 90 degrees anticlockwise around the character center; the key word blocks in the lower right group D2, the words in the key word blocks, are rotated 90 ° clockwise around the word center. The key word blocks in the top left group a1 and the top right group B1, the words in the key word blocks are unchanged, and the words in the bottom left group C1 and the bottom right group D1 are rotated 180 ° clockwise around the word center. Therefore, when the character two-dimensional code is placed on a square table, a person on the square table can easily acquire the content transmitted on the character two-dimensional code pattern in the direction.
In the figure, a1 represents only the above-mentioned group a1 inner part content, B1 represents only the above-mentioned group B1 inner part content, C1 represents only the above-mentioned group C1 inner part content, D1 represents only the above-mentioned group D1 inner part content, a2 represents only the above-mentioned group a2 inner part content, B2 represents only the above-mentioned group B2 inner part content, C2 represents only the above-mentioned group C2 inner part content, and D2 represents only the above-mentioned group D2 inner part content.
At this time, the text two-dimensional code content is generated, the text two-dimensional code pattern is also replaced, and finally, according to the step S15, the text two-dimensional code content and the text two-dimensional code pattern are associated to produce the text two-dimensional code. The character two-dimensional code patterns can be scanned through a machine to obtain the content of the character two-dimensional code, and meanwhile, certain content of the character two-dimensional code can be obtained from the character two-dimensional code patterns through naked eyes.
The text two-dimensional code content is made into a square two-dimensional code through the above S11, and a square two-dimensional code element is extracted. S12 extracts key content of the character two-dimensional code content, S13 generates a key content block by carrying out binarization on the key content, S14 replaces a square two-dimensional code element with the key content block to obtain a character two-dimensional code pattern, and finally, S15 associates the character two-dimensional code pattern with the character two-dimensional code content to generate a character two-dimensional code.
Compared with a square two-dimensional code, the character two-dimensional code has the advantages that the character two-dimensional code pattern is a key content block which can be identified by naked eyes and a code scanning machine, and the square two-dimensional code pattern is a square two-dimensional code element which is only identified by the code scanning machine and is composed of small black blocks, so that the character two-dimensional code pattern can transmit information more than the square two-dimensional code pattern, and meanwhile, a picture can be introduced into the character two-dimensional code pattern, so that the character two-dimensional code not only has higher readability, but also has diversification.
The text two-dimensional code generation method and the specific use case are explained in detail based on some scenes as follows:
referring to fig. 2, fig. 8 and fig. 9, fig. 2 is a flowchart illustrating a first embodiment of a text two-dimensional code generating method according to the present invention.
In this embodiment, the text two-dimensional code is applied to a zoo, and first, according to step S201, the text two-dimensional code content is set as a zoo map, and then step S202 is performed to generate a square two-dimensional code, and then according to step S203, a square two-dimensional code element of the square two-dimensional code is extracted.
Then, according to step S204, the key content of the zoo map is extracted, and the zoo map belongs to the visual work, so that the "map" and the "zoo" can be extracted as the key words, or according to step S205, the "map" and the "zoo" can be set by the staff.
After the keyword setting is completed, according to step S206, the binary processing is performed on the two words "map" and "zoo" by using the preset database to obtain a keyword block, where the keyword block has a visual effect of the two words "map" and "zoo".
Then, in step S207, the square two-dimensional code pattern is screened to screen out 1 × 2 and 2 × 1 black blocks. After the screening is completed, scattered 1 × 1 black blocks are replaced by 1 × 2 and 2 × 1 rectangular blocks by using an error correction code of a two-dimensional code. In addition, rectangular blocks 1 × 2 and 2 × 1 times as large as the rectangular blocks 2 × 4 and 4 × 2 can be preferentially screened out according to requirements of zoo staff, and replaced by key word blocks with the font size enlarged twice. In the replacement, the weights of the map block and the zoo block can be set according to the step S208, and the weight is set according to the ratio of 1: 2, are substituted. Therefore, the rectangular blocks in the original square two-dimensional code are replaced by the keyword blocks, and the readability of the two-dimensional code pattern is improved.
Further, the fonts in the keyword block in the character two-dimensional code pattern may be rotated according to step S209 in such a manner that each character is rotated around its own centroid. The key word blocks with different character orientations can be obtained, so that the characters such as 'maps' and 'zoos' can be seen by identifying the character two-dimensional code patterns from multiple directions. Thereby achieving an improvement in the readability of the two-dimensional code pattern. And after the conversion is finished, according to the step S210, obtaining a character two-dimensional code pattern.
And finally, according to the step S211, associating the character two-dimensional code pattern with the character two-dimensional code content to generate a character two-dimensional code. The text two-dimensional code pattern obtained at this time is a map or zoo oriented by different texts, and the content is a map of the zoo. The character two-dimensional code is placed on a platform at the entrance of the zoo, tourists surrounding the zoo can know the information of the character two-dimensional code through the character two-dimensional code patterns, namely the tourists can roughly know that the content of the character two-dimensional code is the map of the zoo by seeing the character two-dimensional code with the patterns formed by the map and the zoo with different character orientations.
In addition, a character two-dimensional code can be placed at each animal hall mouth of the zoo, for example, a plurality of character two-dimensional codes are placed at the mouth of the sika deer hall, and the contents of the two-dimensional codes are respectively set into a section of voice for introducing the sika deer, a section of video for introducing the sika deer, or photos of a plurality of sika deer and the sound of the sika deer. Then, the sika, the voice, the introduction, the video, the picture and the sound are respectively extracted, and the weight of the sika can be set to be lower as the sika is positioned at the mouth of the sika and the two-dimensional code is hung on the wall according to the requirements of workers in the zoo, and meanwhile, key content blocks with downward font orientation are not set, so that more key contents in the generated text two-dimensional code pattern are the voice, the video, the introduction, the picture and the sound, and a user can more accurately obtain the text two-dimensional code contents through the text two-dimensional code pattern before code scanning.
Referring to fig. 3, fig. 10, and fig. 11, fig. 3 is a flowchart illustrating a text two-dimensional code generating method according to a second embodiment of the present invention.
In this embodiment, the two-dimensional character code is applied to an exhibition hall, and one two-dimensional character code can be placed on each counter or parcel according to the exhibition content of the exhibition hall.
When the exhibition content is a document, the text two-dimensional code content is set as the document according to step S301, then the block two-dimensional code is generated according to step S302, then the block two-dimensional code element is extracted according to step S303, then the name and author of the document are extracted as keywords according to step S304 by using the preset database, and if the name author is not detailed, the noun with a large number of appearing words is extracted as the keywords according to step S305 or the keywords are set by the staff.
When the exhibition content is a section of event, the text two-dimensional code content is set into a short video taking the section of event as a subject, and then nouns of the exhibition event are extracted by using a preset database and taken as keywords or the keywords are set by staff.
Then, according to step S306, binary processing is performed on the extracted keyword to obtain a keyword block, and then according to step S307, the square two-dimensional code element in the square two-dimensional code is replaced by the keyword block, and at this time, according to step S308, the weight of the key content block is set, and the replacement is performed according to the weight. The size of the key content block may also be changed as per step S309. When the character proportion of the key content block is low in the whole block, namely the blank part of the character is too much, filling the ground color of the key content block according to the step S310, then generating a character two-dimensional code pattern according to the step S311, and finally associating the character two-dimensional code content with the character two-dimensional code pattern according to the step S312 to generate the character two-dimensional code.
That is, when the content of the exhibition is a sushi's water-tuned song head, the text two-dimensional code pattern that we see is formed by the keyword blocks formed by sushi and the water-tuned song head, because sushi also writes too many "water-tuned song heads", the text two-dimensional code pattern that we see also includes the keyword blocks formed by "there are times in the bright moon", in addition, can also input "song" and "susong slope" as the keyword, make the author's information of the key content of this document show more directly perceived. The exhibition content is a document authentic work or an imitation, and the general information of the exhibition document can be directly known by identifying the character two-dimensional code pattern, so that the specific content can be checked by scanning the code.
When the content of the exhibition is a section of affairs, the character two-dimensional code pattern seen by people is composed of the noun and the keyword block composed of the author of the affairs. The exhibition of affairs mark in the exhibition hall is often through intercepting a plurality of moments, moulds a plurality of static sculpture and show to the visitor, therefore the characters two-dimensional code can show short video to the visitor, lets the visitor can draw this affairs mark more deeply. The static sculpture is difficult for people to obtain what the contents to be displayed are, and at the moment, the character two-dimensional code pattern can inform visitors of approximate relevant contents.
The principle of the invention is that small black blocks in the square two-dimensional code are replaced by characters, so that the character two-dimensional code is generated, the original single square two-dimensional code with poor readability is converted into character two-dimensional codes with various forms and high readability, and the character two-dimensional code pattern is wetted through a series of partitioning, filling, replacing and converting processes, so that a user can obtain main information of the two-dimensional code only by looking at the code without scanning the code.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
