Then, before the product is put on shelf, a person is required to register the traceability information of the product, and then, the current registration mode is that the worker scans the bar code, namely the unique identification information of the product, and then scans the traceability code of the product. That is, registering the tracing information of a product requires two scanning operations, which is time-consuming and labor-consuming. Based on the embodiment of the graphic code provided by the application, a plurality of sub-graphic codes can be arranged in the same graphic code. In this scenario, as shown in fig. 1, the barcode and the tracing code of the product may be set in the same graphic code, so that the same graphic code may include two pieces of information, and a worker may obtain the two pieces of information by scanning the graphic code once.
Fig. 1 is an example of a graphic code, and as shown in fig. 1, a two-dimensional code is a traceability code of a product, and may include three areas, an upper information valid area, a lower information valid area, and a middle information invalid area, where the middle information invalid area is used for accommodating a bar code of the product. By the arrangement mode, the same graphic code can express various information, different sub graphic codes do not cover the information of the other side, and the integrity of the respective information is kept.
For the barcode in fig. 1, a decoding manner of a common barcode may be used for decoding, for a special two-dimensional code, a decoding rule thereof may be set, and the decoding rule is set in a scanning device, such as a smart phone or a scanner, for a specific decoding manner, reference may be made to descriptions of various embodiments described below in the specification, which will not be described herein again. After scanning the two-dimensional code in fig. 1, the scanning device may decode the two-dimensional code according to a set decoding rule to generate the tracing information of the product.
The graphic code described in the present application is explained in detail below. The embodiment of the application provides a graphic code, which comprises a plurality of sub-graphic codes, wherein in the sub-graphic codes, a first sub-graphic code comprises an information effective area and an information ineffective area, and the information ineffective area is used for accommodating at least part of a second sub-graphic code.
In this embodiment, the graphic code may include data that is displayed in a graphic style after information is encoded. After the graphic code is obtained by the scanning device, the graphic code can be decoded to obtain the original information. The original information may include various types of information such as an access link, a payment entry, an advertisement, a login interface, and the like, and may be specifically set according to an application requirement, which is not limited herein. The encoding type of the graphic code may include one-dimensional code, two-dimensional code, multi-dimensional code, and the like. The encoding mode of the one-dimensional Code may include EAN Code, 39 Code, cross 25 Code, UPC Code, 128 Code, 93 Code, ISBN Code, and curdebar Code, the encoding mode of the two-dimensional Code may include Data Matrix, MaxiCode, Aztec, QR Code, Vericode, PDF417, Ultracode, Code 49, Code 16K, and the like, and the multidimensional Code may add the characteristics of the dimensions such as color on the basis of the two-dimensional Code.
In the embodiment of the application, a plurality of graphic codes can be fused in the same graphic code, so that the fused graphic code is an independent graphic code from a visual point of view. Based on this, in the embodiment of the present application, the graphic code may include a plurality of sub-graphic codes, where the plurality of sub-graphic codes may be respectively used to express different information, or may be partially or completely used to express the same information, and the present application is not limited herein. In addition, the plurality of sub-pattern codes may have different encoding types, or may partially or entirely have the same encoding type. For example, the graphic code may be generated by one two-dimensional code and one-dimensional code, or may be generated by two-dimensional codes, one barcode, and one multi-dimensional code, which is not limited in this application.
In the embodiment of the present application, the sub-graphic code may include a first sub-graphic code and a second sub-graphic code. It should be noted that, in the description of the present embodiment, the terms "first", "second", "third", etc. are used for descriptive purposes only and for distinguishing similar objects, and there is no precedence between the two, and no indication or implication of relative importance should be understood. In addition, in the description of the present embodiment, "a plurality" means two or more unless otherwise specified. The first sub-graphic code may include an information valid area and an information invalid area, where the information valid area may include valid information, and the information invalid area does not include valid information. The information invalid region can be used for accommodating the second sub-graphic code, so that the first sub-graphic code and the second sub-graphic code can be fused together, and information of the other side can be covered in a complementary mode, namely code identification of each side is not affected.
In one embodiment of the present application, the information valid region of the first sub graphic code may include a plurality of sub regions separated from each other. In an example, as shown in fig. 2, the information valid region of the first sub-graphic code may include an upper sub-region and a lower sub-region that are separated from each other, that is, an information valid sub-region 1 and an information valid sub-region 2, and an information invalid region of the first sub-graphic code is between the two sub-regions, and may be configured to accommodate a second sub-graphic code. In one example, the two-dimensional code may be arranged as two sub-areas separated from each other, one above the other, and the barcode may be arranged in the two sub-areas. In another example, the information valid area may further include four sub-areas separated from each other, so that the information invalid area formed in the middle may be provided with a plurality of second sub-graphic codes, such as four bar codes and a two-dimensional code. Of course, in another example, it is also possible to divide the barcode into two sub-regions and to arrange the two-dimensional code between the two sub-regions. It should be noted that, in the present application, neither the number of the information valid area partitions nor the number of the second sub-graphic codes that can be accommodated in the information invalid area is limited.
In another embodiment of the present application, the information ineffective area is set as a hollow area of the information effective area. In this embodiment, the second sub-pattern code may be completely surrounded by the first sub-pattern code. As shown in fig. 3, compared with a square-filled complete two-dimensional code in the related art, the two-dimensional code provided in the embodiment of the present application may have a hollow area in the middle, where the hollow area is an information invalid area and may be used to accommodate a second sub-graphic code such as a barcode. Certainly, a plurality of second sub-graphic codes can be accommodated in the same information invalid area, and a plurality of hollow areas which are not communicated with each other can be further arranged in the first sub-graphic code, and each hollow area can also be used for accommodating at least one second sub-graphic code.
It should be noted that the arrangement manner of the information valid area and the information invalid area of the first sub-graphic code is not limited to the above example, for example, one or more corners of the rectangular first sub-graphic code may also be arranged as the information invalid area, and the second sub-graphic code is at least partially accommodated in the information invalid area, and other modifications may also be made by those skilled in the art in light of the technical spirit of the present application, but all shall be covered by the protection scope of the present application as long as the functions and effects achieved by the second sub-graphic code are the same as or similar to those of the present application.
It should be noted that the sub-graphic codes may include not only one-dimensional codes and two-dimensional codes, but also multi-dimensional codes, and the relationship between the sub-graphic codes may be any combination, for example, the two-dimensional codes may be provided with an information invalid region for barcodes, and the barcodes may be provided with an information invalid region for accommodating the multi-dimensional codes. Other modifications are possible in light of the above teachings and may be practiced by those skilled in the art, and it is within the scope of the appended claims.
For the graphic code provided by any of the above embodiments, another aspect of the present application further provides a method for encoding the graphic code, and the method for encoding the graphic code is described in detail below with reference to the accompanying drawings. Fig. 4 is a schematic method flow diagram of an embodiment of a graphic code encoding method provided in the present application. Although the present application provides method steps as shown in the following examples or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In the case of steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed sequentially or in parallel (for example, in the context of parallel processors or multi-thread processing) according to the embodiments or the method shown in the drawings when the method is executed in a practical graphic code encoding process or device.
Specifically, an embodiment of the graphic code encoding method provided in the present application is shown in fig. 4, where the method may include:
s401: a plurality of information is acquired, including first information and second information.
S403: and encoding the first information, so that the encoded first information is arranged in the information effective area of the first sub-graphic code.
S405: encoding the second information into the second sub-graphic code.
S407: and at least partially arranging the second sub-graphic code in an information invalid area of the first sub-graphic code.
In this embodiment of the application, the obtained information may include original information encoded into an image code, and from the aspect of content, the information may include a link, an advertisement, a login interface, a payment entry, a member entry, and the like, and the expression manner of the information may include characters, words, pictures, and the like. In one example, in the process of setting a graphic code of a certain product to be shipped out of a factory, product unique identification information and traceability query address information of the product need to be set on an external package of the product through the graphic code, wherein the unique identification information is a digital character string "69528368296813", and the traceability query address information is a character string "http:// 123. china. com/v 0/chaxun/". The information that needs to be expressed by the graphic code may also include a public access, a coupon pickup access, an opinion feedback access, etc. of the product business platform.
As described above, in the graphic code, the first sub graphic code includes the information valid area and the information invalid area, and then the first information may be set in the information valid area of the first sub graphic code. In the above example, the product unique identification information may be the second information, and the product unique identification information "69528368296813" may be encoded into a bar code by using an EAN encoding method. For the first information, namely the tracing query address information is a character string http://123. china. com/v0/chaxun/, after the first information is encoded, the encoded information is arranged in the information effective area of the first sub-graphic code.
In an embodiment of the present application, in the process of performing the first information, first, the first information may be encoded into a plurality of information symbols, where the information symbols may include binary symbols such as "0" and "1", and of course, may also include other binary symbols, which is not limited herein. The method for encoding the first information into the information symbol may include a method for converting information into the information symbol in encoding methods such as Data Matrix, MaxiCode, Aztec, and QR Code, which is not limited in this application. Then, a graphic code template may be obtained, in which an information valid area and an information invalid area are respectively set. And finally, setting the plurality of information code elements in an information effective area of the graphic code template to generate the first sub-graphic code. The graphic code template may be a preset template with a fixed size, and the template may include a fixed position, an information valid area with a fixed size, and an information invalid area. Based on this, the information code element is arranged in the information effective area, and the first sub-graphic code can be generated.
Of course, in other embodiments, the preset graphic code template may include a plurality of different specifications, for example, having different information valid area sizes or different information invalid area sizes, to meet different requirements. In practical applications, the size of the information effective area required for different numbers of information symbols is different. Based on this, in one embodiment, after the first information is converted into information symbols, the number of information symbols may be obtained to determine a graphic code template having a size matching the number of information symbols. In an embodiment, the size of the preset graphic code template may include 400 × 400, 300 × 300, 250 × 200, and the like, and the setting manner of the information valid region and the information invalid region in the preset graphic code template may include the manner provided in any of the embodiments described above, which is not described herein again. Before encoding the first information into a plurality of information symbols, the first information may be preprocessed by a plurality of information such as encryption, for example, by converting the first information into a string of a fixed number of bits by a hash algorithm, and then encoding the string into a plurality of information symbols.
In the embodiment of the present application, in the process of setting the information invalid region in the graphic code template, a mask region may be set in the graphic code template. Although some mask regions are set in the two-dimensional code in the related art in order to increase the fault tolerance of the two-dimensional code, the mask regions are set in the related art in order to increase the fault tolerance, and the technical purpose of the setting is different. In addition, the mask area in the related art is too small to accommodate other sub-graphic codes, and it is difficult for a user to confirm which areas are mask areas and which are not, because the encoding process is complicated. The mask area in the embodiments of the present application may be of sufficient size to accommodate other sub-graphic codes. In one example, the graphic code template corresponding to 400 pixels by 400 pixels may have a mask area with a size of 100 pixels by 50 pixels as the information invalid area in the middle. Then, for the graphic code template, the remaining area with the size of (400 pixels × 400 pixels — 100 pixels × 50 pixels) may be used as the information valid area of the graphic code template, that is, the information symbol after the first information is encoded may be set in the information valid area according to a certain rule. Of course, in other embodiments, the mask region may include not only a rectangle, but also any other shape, such as a circle, an ellipse, a rectangle, a star, a heart, and so on, which is not limited herein.
In this embodiment of the application, for a case that the information valid region includes a plurality of sub-regions separated from each other, the first information may be encoded to generate an initial graphic code in addition to the manner of using the preset template. The initial graphical code may then be divided into a plurality of sub-regions that are separated from each other. In an example, the first information may be encoded into a two-dimensional code by using any manner in the related art, and then, the two-dimensional code may be divided into a plurality of sub-regions, where the divided shape may be a rectangle or a special shape, and the number of the divided sub-regions may be two sub-regions or four sub-regions, which is not limited herein. After being divided into a plurality of sub-regions separated from each other, an information invalid region may be set, and the plurality of sub-regions and the information invalid region may be combined into the first sub-graphic code. In addition, the layout of the plurality of sub-regions may include any manner, such as a parallel layout, a vertical layout, and the like, which is not limited herein.
It should be noted that the first sub-graphic code and the second sub-graphic code are only two exemplary graphic codes in the graphic codes, and for information other than the first information and the second information in the plurality of information, a manner of encoding the first information into the first sub-graphic code and encoding the second information into the second sub-graphic code may be referred to, which is not described herein again.
In this embodiment, the decoding priorities of the plurality of sub-graphic codes may also be set respectively. Specifically, the decoding priorities of the plurality of sub-graphic codes may be determined according to priorities of information represented by the sub-graphic codes, wherein the higher the decoding priority, the decoding is performed first. For example, in a payment scenario, the get red envelope and the payment entry are respectively set as the sub-graphic codes, and the two sub-graphic codes are set in the same graphic code. Then, the user may wish to collect the red envelope and pay for it when scanning. Therefore, the decoding priority of the sub-graph code corresponding to the red envelope can be set to be higher than that of the sub-graph code used for the payment entrance pair.
As for the graphic code provided in any of the above embodiments, another aspect of the present application further provides a decoding method of the graphic code, as shown in fig. 5, the decoding method may include:
s501: acquiring the graphic code, and identifying a sub-graphic code in the graphic code;
s503: and decoding the sub-graph code according to the decoding rule of the sub-graph code.
In the embodiments of the present application, the scanning device is used to scan the graphic codes described in the above embodiments, and after obtaining the graphic codes, the scanning device can identify the sub-graphic codes in the graphic codes, and decode the sub-graphic codes according to the decoding rules of the sub-graphic codes. The scanning device can comprise any equipment with the functions of scanning and identifying graphic codes, such as a scanning gun, a smart phone, a scanner and the like.
The graphic code provided by the embodiments of the present application includes a first sub-graphic code and a second sub-graphic code, where the second sub-graphic code is at least partially accommodated in an information invalid region of the first sub-graphic code. Then, if the second sub-graphic code does not include the information invalid region, the second sub-graphic code may be decoded using a decoding rule of the second sub-graphic code. For a first sub-graphic code including an information invalid region, an information valid region of the first sub-graphic code may be determined first, and then the information valid region may be decoded according to a decoding rule of the information valid region.
In another embodiment of the present application, as described above, for a case that the information valid region includes a plurality of sub-regions separated from each other, the plurality of sub-regions may be spliced into an original graphic code. And then, decoding the original graphic code according to the decoding rule of the original graphic code. Of course, the scanning device may be provided with a manner how to position the plurality of sub-regions and a splicing manner of the plurality of sub-regions, and based on this, when the scanning device acquires the type of graphic code, the scanning device may position and splice the plurality of sub-regions according to the set positioning manner and splicing manner.
In practical applications, when the graphic code includes a plurality of sub-graphic codes, if the scanning device can identify the plurality of sub-graphic codes, there is a problem that which sub-graphic code is preferentially processed or which sub-graphic code/sub-graphic codes are processed. Based on this, in the embodiment of the present application, in the above case, the decoding priorities of the plurality of sub-graphic codes may be determined. Corresponding to the embodiment of setting the decoding priority of each sub-graphic code in the above encoding manner, the decoding priority of the plurality of sub-graphic codes may be determined, and the plurality of sub-graphic codes are decoded according to the decoding rules of the plurality of sub-graphic codes, respectively, based on the decoding priority.
In another embodiment of the present application, in the case that the graphic code includes a plurality of sub-graphic codes, an application environment is identified, and then, a target sub-graphic code that needs to be decoded may be determined according to the application environment. In an exemplary scenario, a graphic code includes a first sub-graphic code encoded by a payment portal and also includes a second sub-graphic code encoded by a member portal. When the user uses the graphic code to pay a cashier in a supermarket, a scanning device of the supermarket can identify the current application environment as a payment environment, and can decode only the first sub-graphic code to realize payment.
In another embodiment of the present application, in a case that the graphic code includes a plurality of sub-graphic codes and decodes the sub-graphic codes to obtain a plurality of pieces of information, the type of the decoded information may be sent to a user, so that the user may select the required information. In an exemplary scenario, a graphic code includes a first sub-graphic code obtained from a payment entry code and also includes a second sub-graphic code obtained from a red envelope pickup entry code. When the user uses the graphic code to pay, the scanning device can identify the payment entrance and the red packet getting entrance, and the two information entrances are displayed to the user in a reminding message mode, so that the user can select the required information. The user can choose to receive the red envelope or directly pay after receiving the prompt message, and the background can display the information chosen by the user after receiving the choice of the user.
In another embodiment of the present application, the information expressed by the sub-graphic codes in the graphic codes may be the same information, for example, the information to be expressed is very important information, and only in the case that the information decoded by the sub-graphic codes in the graphic codes is consistent, the information expressed by the graphic codes can be confirmed to be correct. Based on this, after decoding each of the plurality of sub-pattern codes in the pattern code to obtain information, it can be determined whether the information corresponding to each of the plurality of sub-pattern codes is the same. And in the case that the contents are determined to be the same, displaying the contents of the information. Otherwise, it can be determined that the information expressed by the graphic code is problematic.
In other embodiments, the printed materials of the first and second sub-graphic codes may be different, so that the reading devices of the first and second sub-graphic codes are different. Wherein the printing material may include: infrared sensitive material, printing ink, metal material, conductive material, photosensitive material and thermosensitive material. For example, the graphic code printed by the ink can be identified by taking a picture, and the graphic code printed by the infrared sensitive material can be obtained by scanning by a special infrared sensitive device and cannot be identified by a camera. Thus, the provision of the sub-graphic codes as different printed materials may enable different reading devices to read different sub-graphic codes. In one example, a smart phone of a user generally intelligently utilizes a camera to shoot an image and then recognizes the image, so that the graphic code on one product comprises two sub-graphic codes, wherein one sub-graphic code is a tracing information inquiry inlet acquired by a common user, the other sub-graphic code is an inlet for a merchant to enter tracing information, the two sub-graphic codes are arranged in the graphic code, then, the sub-graphic code corresponding to the tracing information inquiry inlet can be printed by ink, and the inlet for entering the tracing information is printed by an infrared photosensitive material, so that different users can acquire different information by using different devices.
Corresponding to the product recommendation method, as shown in fig. 6, the present application further provides a device for reading a graphic code according to various embodiments of the present application, where the device includes a scanning component, a processor, and a memory for storing instructions executable by the processor. The scanning component is used for scanning and acquiring the graphic code, an infrared sensing reading device, a camera device and the like. When the processor executes the instruction, the decoding method of the graphic code according to any one of the above embodiments is realized.
In another aspect, the present application further provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions, when executed, implement the steps of the encoding method and the decoding method of the graphic code described in any of the above embodiments.
The computer readable storage medium may include physical means for storing information, typically by digitizing the information for storage on a medium using electrical, magnetic or optical means. The computer-readable storage medium according to this embodiment may include: devices that store information using electrical energy, such as various types of memory, e.g., RAM, ROM, etc.; devices that store information using magnetic energy, such as hard disks, floppy disks, tapes, core memories, bubble memories, and usb disks; devices that store information optically, such as CDs or DVDs. Of course, there are other ways of storing media that can be read, such as quantum memory, graphene memory, and so forth.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
