Then the gathering client may send the two-dimensional code image shown in fig. 3 to the server. The server may store the two-dimensional code picture. Further, the collecting server can also send the code value "hello" corresponding to the two-dimensional code shown in fig. 3 to the server. The server may store the code value "hello".
In another embodiment, the barcode picture stored by the server may be sent by the merchant client corresponding to the barcode. Specifically, after the merchant client generates a first barcode picture, the first barcode picture may be sent to the server. The server can receive and store a first barcode picture sent by a merchant client. Further, the merchant client can also send a first code value corresponding to the first barcode picture to the server. Then, the server may further store a first code value corresponding to the first barcode picture.
In one embodiment, the server may further store the identity information corresponding to the barcode picture in advance. The identity information may include: address information and/or name information. Specifically, the address information may be address information where a bar code in the bar code picture is located and/or a name of an object corresponding to the bar code in the bar code picture. For example, in an application scenario, if a barcode in a first barcode picture is a two-dimensional code on a public bicycle stake, the identity information of the first barcode picture may be location information of the public bicycle stake. In another application scenario, if the barcode in the first barcode picture is a public number two-dimensional code of a merchant, the identity information of the first barcode picture may be a name of the merchant and/or address information of the merchant.
Further, the picture pre-stored by the server may include: and the staging stores the bar code picture according to the identity information. Specifically, the method may include: and the server allocates the barcode picture of the storage address according to the identity information. In one application scenario, a public bike rental lot may have multiple public bike posts, and a post may have a two-dimensional code. Since the address information corresponding to the plurality of the stakes at the rental point is the same, the plurality of the two-dimensional codes at the rental point may correspond to the same identity information, and the two-dimensional code pictures with the same identity information may be stored at the same position. By distributing the storage position for the stored bar code picture by using the identity information, the corresponding bar code pictures with the same or similar object names and the same or similar address information can be stored at the same position, and the stored data can be managed and searched conveniently.
The server can receive a decoding request sent by the code scanning client. The server can acquire the barcode picture to be identified in the decoding request.

The server may determine, according to the identity information corresponding to the barcode picture to be recognized, that the candidate barcode picture may include: the barcode picture with the identity information identical to that of the barcode picture to be identified can be used as the candidate barcode picture.
In an application scenario, multiple two-dimensional code pictures with the same address information may be stored at the same position of the server, for example, address information corresponding to two-dimensional codes on 20 bicycle posts stored at the storage position "position 1" of the server is "beijing city people road No. 1", then, when the two-dimensional code requested to be decoded by the code scanning client is the two-dimensional code shown in fig. 2, and the identity information corresponding to the two-dimensional code is "beijing city people road No. 1", the two-dimensional codes on 20 bicycle posts stored at the storage position "position 1" may be taken as candidate barcode pictures. The server may screen out the barcode picture with the highest similarity to the barcode picture to be identified (e.g., the two-dimensional code picture shown in fig. 3) from the 20 candidate barcode pictures as the target barcode picture.
By utilizing the identity information, the stored bar code picture can be preliminarily screened, the similarity is further calculated from the result of the preliminary screening, the calculated amount can be reduced, and the matching efficiency of the bar code picture is improved.
S106: and the server sends the target bar code picture to the code scanning client.
The server may send the target barcode picture to the barcode scanning client.

In one embodiment, the code scanning client may receive the target barcode picture, identify a target code value corresponding to the target barcode picture, and use the identified target code value as a code value corresponding to the barcode picture to be identified.
For example, if the barcode picture to be identified that cannot be identified and is sent by the barcode scanning client to the server is the two-dimensional code picture shown in fig. 2, and the target barcode picture fed back to the barcode scanning client by the server is the two-dimensional code picture shown in fig. 3, the barcode scanning client can identify that the code value corresponding to the two-dimensional code is "hello", and use the code value "hello" as the code value of the two-dimensional code shown in fig. 2.
It should be noted that, in the implementation provided in this specification, the code scanning client and the collecting client may be the same client or different clients. For example, in an application scenario, a client identifies a two-dimensional code, and if the two-dimensional code is successfully identified, the two-dimensional code may be sent to a server, and at this time, the client may be referred to as a collection client; if the client fails to identify one two-dimensional code, a decoding request can be sent to the server, and at this time, the client can be called a code scanning client.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
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 Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (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: ARC 625D, 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 apparatuses, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or implemented 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.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately.

The present invention is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (devices), and computer program products according to embodiments of the invention. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
