Description

Technical Field

[0001] The present invention relates to the field of smart device technology, and in particular to a graphic code, a method and a device for generating and recognizing the graphic code. Background Art

[0002] A graphic code is a graphic identifier that uses black and white graphics of varying sizes arranged according to certain coding rules to express a set of information. The more common graphic codes include QR codes and bar codes. Bar codes, also known as one-dimensional codes, can be used to identify the country of production, manufacturer, product name, book classification number, user account number and other information of an item. QR codes can be used to identify equipment numbers, bill identifiers, product names, user accounts, payment accounts and other information. Graphic codes are widely used in many fields such as commodity circulation, book management, mobile payment, and postal management.

[0003] In the prior art, two-dimensional codes and one-dimensional codes are generally used independently. One-dimensional codes are generally printed on product packaging boxes or packaging bags, and for the convenience of scanning, two-dimensional codes are generally printed or pasted near the one-dimensional code, for example, the two-dimensional code is located above the one-dimensional code. Of course, when the one-dimensional code and the two-dimensional code are printed separately, they occupy too much area. In order to save printing area, the two-dimensional code and the one-dimensional code can also be printed in the same area, and the distance between the two is very close.

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0061] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to identifying", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is identified" may be interpreted as "when determining" or "in response to determining" or "when identifying (stated condition or event)" or "in response to identifying (stated condition or event)", depending on the context.

[0062] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0063] The embodiments of the present application can be applied to graphic code recognition by optimizing and dividing the overall area of ​​the graphic code so that the one-dimensional code and the two-dimensional code are filled in a complete graphic code in the form of bars to obtain a graphic code that combines two sub-graphic codes. The recognition of each sub-graphic code will not be affected by other sub-graphic codes, thereby improving the recognition accuracy and efficiency while reducing the code area.

[0064] In the prior art, graphic codes can include multiple types, among which the more common graphic codes are one-dimensional codes and two-dimensional codes. One-dimensional codes are mainly used in industry and commerce, for example, they can track or identify commodities and products to achieve product positioning, traceability and other applications. Two-dimensional codes are mainly used in human-computer interaction fields such as product settlement and identity recognition to perform human-computer interaction. Usually, in order to facilitate product circulation, a product package usually contains both a one-dimensional code and a two-dimensional code. For example, a one-dimensional code and a two-dimensional code are generally printed or pasted on a product packaging bag, and the distance between the two is relatively close. When a user uses a terminal device to scan one of the two-dimensional codes or the one-dimensional code, due to the close distance between the one-dimensional code and the two-dimensional code, the two may affect each other's recognition scanning. For example, when a user uses a mobile phone to scan a two-dimensional code, and the mobile phone is far away from the product, the one-dimensional code may be scanned at the same time. At this time, there will be a scanning conflict between the one-dimensional code and the two-dimensional code, and the user needs to adjust the scanning distance or re-scan the code, and the recognition accuracy and efficiency are not high.

[0065] In order to solve the above technical problems, a graphic code is provided in an embodiment of the present application, and the graphic code may include multiple sub-graphic codes, and the first sub-graphic code in the multiple sub-graphic codes includes a first graphic area and a second graphic area, and the first graphic area and the second graphic area are respectively deployed on both sides of the second sub-graphic code. That is, the graphic code may include a first sub-graphic code and a second sub-graphic code, and the graphic areas of the first sub-graphic code are respectively deployed on both sides of the graphic area of ​​the second sub-graphic code, and the first graphic area and the second graphic area are respectively composed of a first stripe graphic and a second stripe graphic arranged alternately, and the first stripe graphic is used to carry information. By integrating the first sub-graphic code and the second sub-graphic code in the same graphic code, a collection of multiple sub-graphic codes can be realized, but they can be identified according to corresponding recognition rules, so that the recognition of the two sub-graphic codes does not affect each other, thereby improving the recognition efficiency.

[0066] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0067] like Figure 1 FIG. 1 is a schematic diagram of a structure of a graphic code provided by an embodiment of the present application. Figure 1 In the figure, the graphic code 100 may include multiple sub-graphic codes, and the first sub-graphic code 101 among the multiple sub-graphic codes may include a first graphic area 1011 and a second graphic area 1012, and the first graphic area 1011 and the second graphic area 1012 are respectively deployed on both sides of the second sub-graphic code 102.

[0068] The first graphic area 1011 and the second graphic area 1012 are respectively composed of a first strip graphic and a second strip graphic arranged alternately, wherein the first strip graphic is used to carry information.

[0069] Optionally, the information carried by the first strip graphics in the first graphic area 1011 and the second graphic area 1012 is generated by arranging the code element information of the first sub-graphic code according to a certain rule.

[0070] The first stripe pattern is used to carry the first information of the first sub-graphic code, and the first stripe pattern is filled with the code element corresponding to the first information of the first sub-graphic code. The graphic area corresponding to the second sub-graphic code carries the second information of the second sub-graphic code, and the graphic area corresponding to the second sub-graphic code is filled with the code element corresponding to the second information.

[0071] For ease of understanding, Figure 1 The shape of the graphical code 100 shown is circular. In some embodiments, Figure 1 The shape of the graphic code shown can also be a rectangle, an axisymmetric or center-point symmetrical polygon, and the embodiment of the present application does not impose too many restrictions on the shape of the graphic code. In practical applications, the shape of the graphic code can be set according to the packaging requirements of the commodity or product.

[0072] In the embodiment of the present application, the graphic code may include multiple sub-graphic codes, which may include a first graphic code and a second graphic code, and the first graphic area and the second graphic area of ​​the first graphic code are arranged on both sides of the second sub-graphic code, so as to integrate the first sub-graphic code and the second sub-graphic code in the same graphic code, and realize multiple sub-graphic codes in the same graphic code. Moreover, the first graphic area and the second graphic area of ​​the first sub-graphic code are respectively arranged on both sides of the second sub-graphic code, which can make the area division of the first sub-graphic code and the second sub-graphic code clearer, so that the recognition process does not affect each other. In addition, the first graphic area and the second graphic area of ​​the first sub-graphic code are composed of a first bar graphic and a second bar graphic arranged alternately, wherein the first bar graphic is used to carry information, and the second bar graphic is arranged alternately with the first bar graphic, which can make the first bar graphic better distinguishable from other first bar graphics, so as to accurately obtain the message carried in the first bar graphic and improve the accuracy of recognition.

[0073] In some embodiments, in order to make the graphic code more beautiful and better identify each graphic code, a mask pattern can be set on the graphic code. The mask pattern can make the graphic code more beautiful and facilitate the identification of the graphic code. When the first sub-graphic code is a bar-shaped two-dimensional code and the second sub-graphic code is a one-dimensional code, since the one-dimensional code does not require a mask pattern, the second sub-graphic code may not cover the mask pattern, but cover the mask pattern on the first sub-graphic code. In order to match the first sub-mask pattern with the first bar pattern and the second bar pattern of the first sub-graphic code, the mask pattern can be arranged in a way that the first bar pattern and the second bar pattern are arranged alternately, and the mask pattern can be set to a third bar pattern and a fourth bar pattern arranged alternately. Among them, the third bar pattern matches the shape and quantity of the first bar pattern, and the fourth bar pattern matches the shape and quantity of the second bar pattern. The third bar pattern is filled with a preset bar mask pattern, and the fourth bar pattern can be filled with a preset mask pattern. In order to reduce the complexity of recognition, since the second bar pattern does not carry specific information, the fourth bar pattern can be the same as the second bar pattern.

[0074] like Figure 2 FIG. 1 is a structural diagram of another embodiment of a graphic code provided in an embodiment of the present application, and FIG. Figure 1 The difference between the graphic code of the illustrated embodiment is that the second sub-graphic code 102 includes an information valid area 201 and an information invalid area 202 surrounding the information valid area 201;

[0075] The first graphic region 1011 and the second graphic region 1012 are respectively located at two sides of the information invalid region 202 and are respectively adjacent to the information invalid region 202 .

[0076] In some embodiments, the second sub-graphic code is a one-dimensional code, and the graphic shape of the one-dimensional code is generally a rectangle. In order to match the shape characteristics of the one-dimensional code, the shape of the effective information area can be a rectangle, and the intersection of the diagonals of the effective information area coincides with the center point of the graphic code. The invalid information area can be an annular area between an outer ring formed by two sides and two arcs and an inner ring of the rectangle. The length and width of the inner ring of the rectangular ring are equal to the length and width of the effective rectangular information area. The lengths of the two sides of the outer ring of the matrix ring are equal to the lengths of the adjacent sides of the first sub-graphic area and the second sub-graphic area. The two arcs of the outer ring are two line segments parallel to the width of the inner ring formed by connecting the endpoints of the two sides of the outer ring, which are respectively in the minor arcs corresponding to the circular graphic code.

[0077] By presetting the position of the second sub-graphic code in the graphic code, the area of ​​the second sub-graphic code can be quickly determined during the decoding process, thereby realizing rapid recognition of the second sub-graphic code.

[0078] In order to better distinguish the first sub-graphic code from the second sub-graphic code, an information invalid area is set between the information valid area of ​​the second sub-graphic code and the first sub-graphic code, and the information invalid area can be at the code connection point of the first sub-graphic code and the second sub-graphic code to isolate the information valid areas of the first sub-graphic code and the second sub-graphic code.

[0079] Usually, the information invalid area can be set as a blank code word, or set as a predetermined code word that can effectively distinguish the first sub-graphic code and the information invalid area, so as to quickly distinguish the first sub-graphic code and the second sub-graphic code in the graphic code.

[0080] Therefore, in another embodiment provided by the present application, the multiple sub-graphic codes of the graphic code may further include: an isolated graphic code, wherein the isolated graphic code is located in the information invalid area of ​​the second sub-graphic code.

[0081] The isolation graphic code is used to isolate the first graphic area, the second graphic area and the information valid area of ​​the first sub-graphic code.

[0082] The isolation area of ​​the third sub-graphic code can surround the third graphic area of ​​the second sub-graphic code, and the isolation area of ​​the third sub-graphic code has adjacent edges with the third graphic area of ​​the second sub-graphic code, and has adjacent edges with the first graphic area and the second graphic area of ​​the first sub-graphic code.

[0083] As an embodiment, the shape of the graphic code includes a circle;

[0084] The first common side of the first graphic area and the information invalid area, and the second common side of the second graphic area and the information invalid area are two parallel chords of equal length in the circle corresponding to the graphic code.

[0085] like Figure 2 As shown, the first common side L1 between the first graphic area 1011 and the information invalid area 202 and the second common side L2 between the second graphic area 1012 and the information invalid area 202 are two parallel chords of equal length in the circle corresponding to the graphic code.

[0086] In one embodiment of the present application, the first sub-graphic code may include a bar-shaped QR code. According to the generation rules of the QR code, a common QR code may include a three-dimensional positioning point. Similarly, the first sub-graphic code of the embodiment of the present application may include the same three positioning graphics.

[0087] The three positioning patterns are identical in shape, size and pattern.

[0088] The three positioning patterns are located in the first pattern area and the second pattern area of ​​the first sub-pattern code to position the first sub-pattern code.

[0089] For ease of understanding, Figure 3 A schematic diagram of a graphic code provided by an embodiment of the present application is shown, and the graphic code 300 may include multiple sub-graphic codes. Among them, the multiple sub-graphic codes may include a first sub-graphic code 301, and the first sub-graphic code 301 may include a first graphic area 3011 and a second sub-graphic area 3012, and the first graphic area 3011 and the second sub-graphic area are respectively deployed on both sides of the second sub-graphic code 302. The first graphic area 3011 and the second sub-graphic area 3012 of the first sub-graphic code 301 are respectively composed of a first strip graphic M1 and a second strip graphic M2 arranged alternately. Among them, the first strip graphic is used to carry information.

[0090] Figure 3 The first sub-graphic code 301 is a bar-shaped two-dimensional code, and the second sub-graphic code 302 is a one-dimensional code.

[0091] The first stripe graphic M1 is filled with code elements corresponding to the first information, and the second stripe graphic M2 is filled with blank code elements. The blank code elements may refer to code elements that are all 0 or code elements that are all 1. Figure 3 The blank code elements filled in the second strip graph in are code elements with all values ​​being 1.

[0092] The first sub-graphic code 301 may include three positioning graphics. Figure 3 , a display method of three positioning graphics in a graphic code is shown, wherein two positioning graphics 303 and 304 are located in a first graphic area 3011 , and another positioning graphic 305 is located in a second graphic area 3012 .

[0093] The center points of the positioning pattern 303, the positioning pattern 304 and the positioning pattern 305 are connected to each other to form an isosceles right triangle, and the midpoint of the base of the isosceles right triangle coincides with the center point of the graphic code.

[0094] In some embodiments, three positioning graphics can be used to identify the size and direction of the first sub-graphic code, and when the center points of the three positioning graphics are connected to each other, a positioning triangle is formed. The positioning triangle is an isosceles right triangle and the midpoint of its base coincides with the center of the graphic code.

[0095] When the center points of the three positioning graphics are connected to each other, the positioning triangle formed is an isosceles right triangle and the midpoint of its base coincides with the center of the graphic code, so that fast and accurate positioning can be achieved.

[0096] In order to accurately identify each positioning point and make the area utilization rate of the graphic code higher, in a possible design, the three positioning graphics are rectangular.

[0097] Each of the three positioning figures has a vertex intersecting with the edge of the graphic code, and each of the three positioning figures has a diagonal line that is on the same straight line as the center of the graphic code.

[0098] Since the first sub-graphic code may include a first graphic area and a second graphic area, two positioning points may be set in one of the graphic areas, and the remaining positioning points may be set in the other graphic area.

[0099] In yet another possible design, any two of the three positioning patterns may be located in the first pattern area or the second pattern area.

[0100] Any two of the three positioning patterns may be located in the first graphic area, or any two of the three positioning patterns may be located in the second graphic area.

[0101] Further, optionally, the first graphic area may include: a first positioning area and a second positioning area, and the second graphic area may include a third positioning area.

[0102] Alternatively, the second graphic area may include: a first positioning area and a second positioning area, and the second graphic area may include a third positioning area.

[0103] The first positioning pattern is located in the first positioning area, the second positioning pattern is located in the second positioning area, and the third positioning pattern is located in the third positioning area.

[0104] Among them, the center point of the first positioning area is the first positioning point, the center point of the second positioning area is the second positioning point, and the center point of the third positioning area is the third positioning point.

[0105] When the positioning pattern is a rectangle, the center point of the positioning area is the intersection point of the diagonals of the rectangular area corresponding to the positioning pattern.

[0106] During the generation process of the first sub-graphic code of the graphic code, certain parameters may be generated, and these parameters may include version information, redundancy type, encoding type and / or code type of the first sub-graphic code, etc., and the meta-information of the first graphic code may be constituted by the parameters. The meta-information constituted by at least one parameter of the first sub-graphic code may be encoded and set in the meta-information area of ​​the first sub-graphic code.

[0107] The first sub-graphic code also includes: a meta-information area located between two positioning graphics in the same graphic area and adjacent to the information invalid area;

[0108] The meta-information area is used to carry meta-information consisting of at least one parameter of the first sub-graphic code.

[0109] For ease of understanding, we will use Figure 3 The same, the only difference is that the dot pattern is used to distinguish different areas Figure 4 (not shown Figure 3 Taking all the identifications of the first sub-graphic code as an example, the meta-information of the first sub-graphic code can be set between the positioning graphics 303 and the positioning graphics 304, and in the meta-information area 307 adjacent to the information invalid area 306 of the second sub-graphic code.

[0110] As a possible implementation manner, the first sub-graphic code includes a bar-shaped two-dimensional code, and the second sub-graphic code includes a one-dimensional code, a bar-shaped two-dimensional code, or a common two-dimensional code.

[0111] The code element information of the first sub-graphic code can be obtained by encoding the first information according to the generation principle of the two-dimensional code. The encoded code element information is filled in the first bar graph of the alternately arranged first bar graph and the first bar graph of the graphic area corresponding to the second bar graph to obtain the first sub-graphic code. The second sub-graphic code can be obtained by encoding the second information according to the generation principle of the one-dimensional code.

[0112] Optionally, the encoding method of the two-dimensional code used by the first sub-graphic code may include: Data Matrix (matrix data two-dimensional code), MaxiCode (bull's eye code), Aztec (two-dimensional matrix code), QR Code (two-dimensional barcodes, two-dimensional code), etc. The encoding method of the one-dimensional code used by the second sub-graphic code may include: EAN code (European Article Number, barcode), 39 code, cross 25 code, UPC code (Universal Product Code, universal product code), 128 code, 93 code, ISBN code (International Standard Book Number, international book standard number), Codabar code, etc.

[0113] The first information is the specific information identified by the first sub-graphic code, and the second information is the specific information identified by the second sub-graphic code. For example, in the field of commodity settlement, the first information may refer to the information consisting of the payment information of the commodity, and the second information may refer to the information consisting of the product information of the commodity.

[0114] by Figure 3 For example, by scanning the graphic code 300, the first information corresponding to the first sub-graphic code 301 of the graphic code 300 can be identified, and the second information corresponding to the second sub-graphic code 302 of the graphic code 300 can also be identified.

[0115] The process of generating the graphic code may be a process of encoding according to certain encoding rules, and the process of recognizing the graphic code may be a process of decoding according to certain decoding rules.

[0116] In another embodiment provided in the embodiments of the present application, in order to make the edge area of ​​the graphic code more obvious to distinguish it from other graphic codes and achieve rapid identification, the multiple sub-graphic codes may also include: a third sub-graphic code corresponding to the edge padding area that is adapted to the graphic shape of the graphic code.

[0117] The third sub-graphic code is used to fill in the edges of the graphic code with code elements.

The code element obtained after encoding the second information is filled into the area corresponding to the second sub-graphic code to obtain the second sub-graphic code.

[0129] 503: Determine a first graphic area and a second graphic area respectively disposed on both sides of the second sub-graphic code.

[0133] The first sub-graphic code can be obtained by encoding the first information according to a preset first encoding rule.

[0134] The first encoding rule and the second encoding rule may be different.

The blank code element may refer to a code element that is all 0 or a code element that is all 1.

[0137] 505: Determine the graphic codes corresponding to the first sub-graphic code and the second sub-graphic code.

[0138] The multiple sub-graphic codes of the graphic code include a first sub-graphic code and a second sub-graphic code.

[0144] 603: Determine an information invalid area surrounding the information valid area to obtain a second sub-graphic code consisting of the information valid area and the information invalid area.

[0145] When identifying the first information and the second information, in order to quickly distinguish the first sub-graphic code from the second sub-graphic code, an isolation area may be established between the first graphic area and the second graphic area and the second sub-graphic code, and the isolation area may be set as an information invalid area of ​​the information valid area of ​​the second sub-graphic code. The setting of the information invalid area can isolate the areas where the code elements of the first sub-graphic code and the second sub-graphic code are located, so as to quickly distinguish the first sub-graphic code from the second sub-graphic code.

[0146] 604: Determine a first graphic region and a second graphic region that are respectively disposed on both sides of the information invalid region and are respectively adjacent to the information invalid region.

[0147] The first graphic area and the second graphic area are respectively deployed on both sides of the message invalid area, and are adjacent to the message invalid area, and have a common edge.

[0148] 605: Encode the first information so that the encoded first information is set in the first graphic area and the first strip graphic in the second graphic area to obtain a first sub-graphic code.

[0149] The first sub-graphic code further includes a second stripe graphic located in the first graphic area and the second graphic area and arranged alternately with the first stripe graphic.

[0150] 606: Determine the graphic codes corresponding to the first sub-graphic code and the second sub-graphic code.

[0151] In the embodiment of the present application, after determining the first information and the second information, the second information is encoded and set in the information valid area, and an information invalid area that can surround the information valid area is determined to obtain a second sub-graphic code consisting of the information valid area and the information invalid area. The information invalid area of ​​the second sub-graphic code can isolate the information valid area and the first graphic area and the second graphic area of ​​the first sub-graphic code, so as to quickly distinguish the first sub-graphic code from the second sub-graphic code.

[0153] The center point of the graphic code is taken as the intersection point of the diagonal lines of the effective information area;

[0154] Determining an information invalid area surrounding the information valid area to obtain a second sub-graphic code consisting of the information valid area and the information invalid area includes:

[0155] According to the center point of the graphic code and in combination with the information valid area, an information invalid area surrounding the information valid area is determined to obtain a second sub-graphic code consisting of the information valid area and the information invalid area;

[0156] The determining of the first graphic area and the second graphic area respectively arranged on both sides of the information invalid area and respectively adjacent to the information invalid area comprises:

[0157] According to the center point of the graphic code, a first graphic area and a second graphic area are determined to be respectively located on both sides of the information invalid area and are respectively adjacent to the information invalid area.

[0158] Optionally, the invalid information area surrounding the valid information area can be determined based on the center point, shape and size of the graphic code combined with the size of the valid information area to obtain a second sub-graphic code consisting of the valid information area and the invalid information area.

[0159] The first graphic area and the second graphic area respectively disposed on both sides of the information invalid area and respectively adjacent to the information invalid area may also be determined according to the center point, shape and size of the graphic code.

[0160] The information valid area is located in the graphic code, and the center point of the information valid area coincides with the center point of the graphic code. The information invalid area may surround the information valid area, and is adjacent to the first graphic area and the second graphic area and has a common edge.

[0161] As a possible implementation, the shape of the graphic code includes a circle;

[0162] The step of determining, based on the center point of the graphic code, the first graphic area and the second graphic area respectively located on both sides of the information invalid area and respectively adjacent to the information invalid area comprises:

[0163] Determine the radius of the graphic code;

[0164] Determine, according to the center point, shape and radius of the graphic code, a first common side between the first graphic area and the information invalid area and a second common side between the second graphic area and the information invalid area; wherein the first common side and the second common side are parallel chords of equal length in the graphic code;

[0166] Determine that a closed area formed by connecting the second common edge and the arc corresponding to the graphic code where the second common edge is located is the second graphic area.

[0167] The first common side is the chord of the circular graphic code, and the second common side is the chord of the circular graphic code. Each chord of a circle can correspond to a minor arc, so the closed area formed by connecting the first common side and the minor arc corresponding to the graphic code can be determined as the first graphic area. The closed area formed by connecting the second common side and the minor arc corresponding to the graphic code can be determined as the second graphic area.

[0168] When the shape of the graphic code is a circle, the center point of the graphic code is the center of the circular graphic code.

[0173] The code element distribution direction may refer to the arrangement direction of the code elements. Figure 3In the graphic code shown, two of its positioning points are located in the first graphic area, and the other positioning point is located in the second graphic area. It can be determined that the distribution direction of its code elements is from top to bottom and from left to right. That is, when the code elements of the first information are set in the first graphic area and the second graphic area of ​​the first sub-graphic code, the code elements of the first information can be filled from the leftmost side of the graphic code from top to bottom in sequence until they are filled to the rightmost side to obtain the first sub-graphic code.

[0174] In some embodiments, the positioning triangle formed by connecting the center points of the three positioning patterns is an isosceles right triangle and the midpoint of its base coincides with the center of the graphic code.

[0175] According to the center point, shape and radius of the graphic code, the sizes of the three positioning graphics and the positions of their respective center points in the graphic code are determined based on the setting rule that the positioning triangle formed when the center points of the three positioning graphics are connected is an isosceles right triangle and the midpoint of its base coincides with the center of the graphic code;

[0176] According to the sizes of the three positioning patterns and the positions of their respective center points in the graphic code, the three positioning patterns are combined to generate a comprehensive positioning pattern under the setting conditions that each of the three positioning points has a vertex intersecting with the edge of the graphic code and each has a diagonal line on the same straight line as the center of the graphic code;

[0177] The comprehensive positioning graphic is set in the first graphic area and the second graphic area.

[0178] Under the setting conditions that each of the three positioning points has a vertex intersecting with the edge of the graphic code and each has a diagonal line on the same straight line as the center of the graphic code, the three positioning graphics are combined to form a comprehensive positioning graphic. The comprehensive positioning graphic is a graphic formed by combining the three positioning graphics according to the setting conditions.

[0179] Further, optionally, setting the comprehensive positioning graphic in the first graphic area and the second graphic area may include:

[0180] Arrange any two positioning patterns in the comprehensive positioning pattern in the first pattern area, and arrange another positioning pattern in the second pattern area;

[0181] The method further comprises:

[0200] Among them, the graphic code includes: multiple sub-graphic codes; the first sub-graphic code among the multiple sub-graphic codes includes a first graphic area and a second graphic area; the first graphic area and the second graphic area are respectively deployed on both sides of the second sub-graphic code; the first graphic area and the second graphic area are respectively composed of a first strip graphic and a second strip graphic arranged alternately; wherein the first strip graphic is used to carry information.

[0201] The method for recognizing a graphic code provided in the embodiment of the present application can be applied to an electronic device or a server. The electronic device can directly collect the graphic code, and use the method for recognizing a graphic code provided in the present application to recognize the information of the graphic code. The server can be connected to the user terminal. After the user terminal collects the graphic code, the graphic code can be sent to the server. The server can receive the graphic code sent by the user terminal and use the method for recognizing a graphic code provided in the present application to recognize the information of the graphic code.

[0202] 702: Identify the second information carried in the second sub-graphic code.

[0203] 703: Identify the first information carried by the first bar graphic in the first graphic area and the second graphic area corresponding to the first sub-graphic code.

[0209] 802: Detecting a recognition environment for recognizing a graphic code.

[0210] The user can use different electronic devices to scan the graphic code to identify the graphic code. Different electronic devices use different operating systems, and different operating systems constitute different recognition environments. The recognition environment is determined based on the type of electronic device and the operating system of the electronic device. For example, the recognition environment of a mobile phone is different from that of a handheld terminal. A handheld terminal can recognize a one-dimensional code, but cannot recognize a two-dimensional code. The recognition environment of the handheld terminal can be determined as the first recognition environment. The mobile phone can recognize a one-dimensional code and a bar-shaped two-dimensional code. The recognition environment of the mobile phone can be set to the second recognition environment.

By judging the recognition environment, the recognition environment of the first sub-graphic code and the second sub-graphic code in the graphic code can be quickly confirmed, so as to achieve a rapid response of recognition and improve recognition efficiency.

[0215] In some embodiments, if the recognition environment is the second recognition environment, after recognizing the first information carried by the first bar graphic in the first graphic area and the second graphic area corresponding to the first sub-graphic code, the method further includes:

The first sub-graphic code includes a first graphic area and a second graphic area, and the first graphic area and the second graphic area are respectively composed of a first bar graphic and a second bar graphic arranged alternately. This graphic setting can quickly distinguish the first sub-graphic code and the second sub-graphic code in the graphic code. After determining the center point of the graphic code, the information valid area corresponding to the second sub-graphic code in the graphic code and the information invalid area surrounding the information valid area can be determined according to the center point of the graphic code. The code element of the second information is set in the information valid area, and the information valid area and the first graphic area and the second graphic area of ​​the first sub-graphic code are isolated by the information invalid area, so that the independence of the first sub-graphic code and the second sub-graphic code can be made stronger. In the recognition process, the recognition efficiency of the first sub-graphic code and the second sub-graphic code can be improved by buffering the information invalid area.

[0233] As an embodiment, the information valid area may be a rectangle;

[0236] An information invalid area surrounding an information valid area in the graphic code is determined.

[0237] The center point of the graphic code coincides with the intersection of the diagonals of the information effective area.

[0238] In some embodiments, the shape of the graphic code is circular, and the graphic code includes a graphic code;

[0239] Determining, according to the information invalid area in the graphic code, the first graphic area and the second graphic area located on both sides of the information invalid area and adjacent to the information invalid area includes:

[0240] According to the center point, shape and radius of the graphic code, two parallel chords of equal length corresponding to the information invalid area in the graphic code are determined to obtain a first common side between the first graphic area and the information invalid area and a second common side between the second graphic area and the information invalid area;

[0241] Determine a closed area formed by connecting the first common edge and the arc corresponding to the graphic code as the first graphic area;

[0245] Determine the size of the first sub-pattern code and the distribution direction of the code elements according to the three positioning patterns;
