All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In practical applications, the portable device is inconvenient to use because the base library of the portable device is usually copied from a U disk or other third-party storage device, and the updating of the base library has a delay problem. Similarly, in field use of the base library of the portable device, a certain base library picture may be temporarily added, and it is necessary to search for a target corresponding to the base library picture in an image acquired by a camera associated with the portable device, and synchronize the base library picture added in the portable device into a business system of an intranet, so as to perform a large-scale search in an image acquired by a camera associated with the business system (the number of cameras associated with the business system is usually more than that of cameras associated with the portable device) through the business system. Therefore, there is a need for a device that can synchronize the portrait data of the base library of the business system and the base library of the portable device in real time.

Based on this, the embodiment of the invention provides a method, a device and an electronic system for synchronizing an underlying library, which realize the underlying library synchronization of a service system and a portable device through a synchronization server, relieve the problem of the underlying library update lag of the portable device, simplify the update operation of the portable device, and facilitate the popularization and implementation.

The synchronization server 20 further includes: one or more second input and output devices 203; the portable device 30 includes: one or more third input and output means 303 and one or more third image acquisition devices 304.

It should be noted that the components and configuration of the electronic system shown in fig. 1 are exemplary only, and not limiting, and that the electronic system may have other components and configurations as desired.

The first processing device 102, the second processing device 202, and the third processing device 302 may each be one or more processors, which may be a server, an intelligent terminal, or a device or apparatus including a Central Processing Unit (CPU) or other form of processing unit with data processing capability and/or instruction execution capability, which can process data of other components in the electronic system, and can control other components in the electronic system to perform the function of base synchronization.

The first storage 101, the second storage 201, and the third storage 301 may include one or more computer program products, which may include various forms of computer-readable storage media, such as volatile memory and/or non-volatile memory. Volatile memory can include, for example, Random Access Memory (RAM), cache memory (or the like). The non-volatile memory may include, for example, Read Only Memory (ROM), a hard disk, flash memory, and the like. One or more computer program instructions may be stored on a computer-readable storage medium and executed by a processing device corresponding to the storage means to implement the client functionality (implemented by the processing device) and/or other desired functionality in embodiments of the invention described below. Various applications and various data, such as various data used and/or generated by the applications, may also be stored in the computer-readable storage medium. For example: the first computer program, when executed by the first processing device, executes the method for synchronizing the base library on the service server 10 side in the following embodiments of the present invention; the second computer program, when executed by the second processing device, performs the method for synchronizing the base library on the side of the synchronization server in the following embodiments of the present invention; the third computer program, when executed by the third processing device, performs the method for synchronizing the base on the portable device side in the following embodiments of the present invention.

The first image capturing device 104 and the third image capturing device 304 may capture the image of the basement and the image to be detected, and store the captured images in corresponding storage devices for use by other components.

The portable devices 30 in the electronic system are multiple, and the multiple portable devices 30 can jointly maintain the base library set on the service server 10. Of course, the electronic system may include a network device (not shown in fig. 1) such as a gateway besides the service server 10, the synchronization server 20, and the portable device 30, so as to implement information transmission to the corresponding device via the network.

For example, the devices used for implementing the method, apparatus and electronic system for synchronizing an image library according to the embodiment of the present invention may be integrally arranged or dispersedly arranged, such as the processing device, the storage device, and the input and output device on each device of the service server 10, the synchronization server 20, and the portable device 30 may be integrally arranged, and the image capturing device may be arranged at a specific position where an image can be captured. When the above-mentioned devices in the service server 10, the synchronization server 20, and the portable device 30 are integrally provided, the service server 10, the synchronization server 20, and the portable device 30 may be implemented as a smart terminal such as a camera, a smart phone, a tablet computer, a vehicle-mounted terminal, and the like.

An embodiment of the present invention provides a method for synchronizing a base library, where an execution main body of the method is a synchronization server arranged in an external network, and the synchronization server is in communication connection with a gatekeeper (also referred to as a gateway) of a service server, see a flowchart of the base library synchronization method shown in fig. 2, where the method includes the following steps:

step S202, receiving a first Oplog file issued by a gateway; the gateway is a gatekeeper used for isolating an intranet from an extranet, and the first Oplog file is a file generated by updating operation of a business server in the intranet on a first bottom library set in the intranet.

The first Oplog file is a log file, which is generated based on the update operation of the first base library set, and therefore includes information related to the picture corresponding to the update operation of the first base library set, for example, encoding information of a newly added picture or encoding information of a modified picture.

As shown in the schematic diagram of the base-side synchronization application scenario in fig. 3, the service server of the intranet is connected to the synchronization server of the extranet through the gateway in a communication manner, the portable devices a, B, and C of the extranet are connected to the synchronization server, and the portable devices a, B, and C are mobile portable devices distributed in various locations. In practical application, the number of the portable devices may be set according to practical application scenarios, which is not limited to be described in the embodiment of the present invention.

For convenience of description, in the embodiment of the present invention, the base library set on the service server side is referred to as a first base library set, the base library set in the external network is referred to as a second base library set, and all base library sets on the portable device are referred to as a third base library set. The first base library set, the second base library set, and the third base library set in the embodiment of the present invention may include a plurality of base libraries of different types, for example: the primary library of the collection of the pictures of the class of the related to the poison is the primary library of the related to the poison, and the primary library of the collection of the pictures of the class of the related to the gambling is the primary library of the related to the gambling. The pictures in one type of base library and the pictures in other types of base libraries may or may not have partial overlapping pictures.

When the service server generates a first Oplog file based on a first bottom library set updating operation in the intranet, the service server sends the first Oplog file to the synchronization server through the gateway, namely the synchronization server receives the first Oplog file sent by the gateway.

And step S204, updating the second bottom library set in the external network by applying the first Oplog file.

After receiving the first Oplog file, the synchronization server may analyze the first Oplog file to obtain picture information corresponding to the update operation, and then update the second base library set in the external network based on the picture information, where the updated second base library set and the base library of the corresponding first base library set in the service server achieve quasi-real-time synchronization.

And step S206, responding to the bottom library synchronization request of the portable device, and updating a third bottom library set on the portable device based on the updated second bottom library set.

The portable device is a mobile device, in practical application, the portable device is not in a continuous power-on state, the portable device is powered on only when needed, and after being powered on every time, the portable device sends a bottom library synchronization request to the synchronization server so as to update the third bottom library set.

In practical applications, the operating system of the synchronization server is different from that of the portable device, and since the portable device is generally written in python language and deployed on the windows operating system, and the synchronization server is written in java language and deployed on the linux operating system, the portable device and the synchronization server cannot achieve communication connection. Based on this, considering that an ICE (Interactive Connectivity Establishment) is a full-function RPC (Remote Procedure Call Protocol) framework, which may support languages such as C + +, C #, Java, javascript, and Python, in this embodiment of the present invention, the portable device and the synchronization server implement communication connection through an ICE technique, specifically, a communication interface between each portable device and the synchronization server is written into a service.

When the synchronization server receives a bottom library synchronization request of the portable device, the synchronization server updates a third bottom library set on the portable device based on the updated second bottom library set, so that the updated third bottom library set in the portable device and the bottom library information of the updated second bottom library set are synchronized in time.

In the above-mentioned base synchronization method provided in the embodiment of the present invention, the synchronization server disposed in the external network receives the first Oplog file issued by the service server through the gateway, where the first Oplog file is a file generated by the service server based on the update operation of the first base set in the internal network, the synchronization server updates the second base set in the external network by using the first Oplog file, so as to implement the timely synchronization between the first base set in the internal network and the second base set in the external network, and the synchronization server responds to the base synchronization request of the portable device and then updates the third base set on the portable device based on the updated second base set, so as to implement the synchronization between the third base set in the external network and the second base set, which is equivalent to implement the synchronization between the third base set on the portable device and the first base set on the internal network service server, the synchronization mode can quickly realize the synchronization of the base libraries in the mode that the portable equipment sends the synchronization request without configuring additional storage hardware (such as a U disk and the like) and a third-party storage device on the portable equipment, thereby relieving the problem of lag in updating the base libraries of the portable equipment, simplifying the updating operation of the portable equipment and being convenient for popularization and implementation.

In practical applications, the portable devices distributed in various locations also implement registration in the synchronization server through the ICE technology, specifically, as shown in the schematic diagram of the registration method shown in fig. 4, each portable device sends registration information to the synchronization server through the ICE technology, where the registration information includes, but is not limited to, an IP (Internet Protocol), a port (interface communicatively connected to the synchronization server), a repository list, the number of repository pictures, and model version information of an application algorithm of each portable device, so that the synchronization server completes registration of the portable device according to the received registration information. In particular, if a certain portable device has completed registration, the synchronization server also updates the received registration information to the database so that the user inquires the registration information of a certain portable device in the synchronization server.

It should be noted that, since the portable device may have a situation where the operator updates the base list in the case of network outage, the portable device needs to send the base list to the synchronization server after being powered on every time, where the base list is the base list in the third base set.

On the basis of fig. 2, another base library synchronization method is further provided in the embodiment of the present invention, where the execution subject is a synchronization server, and the method focuses on describing a specific process in which the synchronization server updates a second base library set in an external network by applying a first Oplog file. Wherein, the url field of the first Oplog file is encoded for the base64 of the target picture modified or added by the service server, as shown in fig. 5, the method includes the following steps:

Step S502, receiving a first Oplog file issued by a gateway; the gateway is a gatekeeper used for isolating an intranet from an extranet, and the first Oplog file is a file generated by updating operation of a business server in the intranet on a first bottom library set in the intranet.

And step S504, analyzing the first Oplog file to obtain a target picture.

Specifically, a service server and a synchronization server are both provided with a Mongodb database, wherein a base library in the service server is stored in the Mongodb database, and can be directly accessed through a url (uniform resource locator) field of picture information in the Mongodb database. In practical application, the pictures in the Mongodb database can be stored in the data set in groups to form a base library of a type corresponding to each set. Each picture stored in the montodb database may also be provided with a unique identification, which may be characterized by a base64 code.

As shown in fig. 6, in a schematic transmission diagram of a first Oplog file, when the service server updates the first base library set, for example, modifies or adds a target picture, at this time, the update operation is recorded in an Oplog log, and is saved in an ftp (file transfer protocol) directory of the service server. The service server analyzes the Oplog log through the MongoShake service to obtain the url of the target picture, downloads the target picture according to the url, changes the downloaded target picture into a corresponding base64 code, replaces the url of the target picture in the Oplog log by using a base64 code to obtain a first Oplog file, and sends the first Oplog file to the ftp directory of the synchronization server through the gateway.

After the synchronization server receives the first Oplog file, the synchronization server analyzes the first Oplog file through the mongosharke service to obtain a base64 code in a url field of the first Oplog file, and a target picture is generated based on the base64 code.

The MongoShake service is a general platform service written in the golang language, and copies data stored by the Mongodb by reading an Oplog operation log of a Mongodb database, so that specific requirements are realized by analyzing the operation log. Therefore, the synchronization server analyzes the operation log in the first Oplog file through the mongosharke service, so that the base64 code in the url field of the first Oplog file can be obtained, and the target picture can be generated according to the base64 code.

Step S506, determining whether the target picture is a new added picture according to the identifier of the target picture. If yes, go to step S508; if not, step S510 is performed.

The identifier of the target picture in this embodiment may include two parts, i.e., a base library ID and a picture ID, for example: and taking the first 16 bits in the base64 code in the url field as the identification of the target picture, wherein the codes of the 1 st to 8 th bits in the first 16 bit code are bottom library IDs, and the codes of the 8 th to 16 th bits are picture IDs.

After the synchronization server obtains the target picture, whether the target picture is a newly added picture can be judged according to the identification of the target picture, specifically, a target base corresponding to the identification of the target picture is searched in the second base set, whether the picture ID of the target picture exists is checked in the target base, and if the picture ID exists, the picture is not the newly added picture and is modified on the basis of the original picture; if not, the instruction book is a new added picture.

Of course, other picture identification manners may also be adopted, for example, the target base library ID and the picture ID are carried in other fields of the first Oplog file except for the url field, and the base64 in the url field may be encoded only for the picture. Alternatively, the target base library ID is carried in other fields of the first Oplog file except the url field, and the base64 code in the url field may only contain the picture ID and not the base library ID.

And step S508, adding the target picture in a second base library set of the extranet.

At this time, because the target picture is a newly added picture, the synchronization server adds the target picture to the base library corresponding to the second base library set, so that the updated second base library set and the updated first base library set in the service server realize quasi-real-time synchronization. The quasi-real-time condition here means that a gatekeeper exists between the synchronization server and the service server, so that data transmission has a certain delay through the gatekeeper, but the base information of the finally updated second base set and the updated first base set in the service server is kept consistent.

Step S510, replacing the corresponding picture identified in the second base library set with the target picture.

When the target picture is the modification of the original picture by the service server, at the moment, the synchronization server replaces the picture corresponding to the identifier in the second base library set by the application target picture, so that the updated second base library set and the updated first base library set in the service server are synchronized in a quasi-real-time manner.

Step S512, responding to the bottom library synchronization request of the portable device, and updating a third bottom library set on the portable device based on the updated second bottom library set.

According to the method, the base64 coding mode of the target picture is carried in the url field of the first Oplog file, so that the synchronization server can generate the target picture based on the base64 coding, the target picture is updated in the second base set, the second base set and the first base set can be synchronized in time, and the timeliness and the accuracy of base synchronization operation of subsequent portable equipment are guaranteed.

On the basis of fig. 2, another base library synchronization method is further provided in the embodiment of the present invention, where the execution subject is a synchronization server, and the method focuses on a specific process of updating a third base library set on a portable device based on an updated second base library set. As shown in fig. 7, the method comprises the steps of:

Step S702, receiving a first Oplog file issued by a gateway; the gateway is a gatekeeper used for isolating an intranet from an extranet, and the first Oplog file is a file generated by updating operation of a business server in the intranet on a first bottom library set in the intranet.

Step S704, update the second bottom library set in the extranet with the first Oplog file.

The steps S702 to S704 can refer to the steps S202 to S204, and the embodiment of the present invention is not described in detail herein.

Step S706, responding to the bottom library synchronization request of the portable equipment, and determining a target bottom library corresponding to the portable equipment according to the service requirement; and the bottom library synchronous request carries bottom library list information corresponding to a third bottom library set on the portable equipment.

Specifically, when the portable device is in communication connection with the synchronization server through the ICE technology, that is, the default synchronization server receives a base synchronization request of the portable device, where the base synchronization request carries base list information corresponding to a third base set on the portable device, where the base list information includes a base list identifier and the number of base pictures, so that the synchronization server determines a target base corresponding to the portable device according to a service requirement. For example, the portable device a sends a base library synchronization request to the synchronization server, and the service requirement of the portable device a is a picture set of the virus-involved person, the synchronization server determines a target base library corresponding to the portable device a according to the service requirement. It should be noted that, here, the service requirement may be set by an operator of the portable device according to an actual application scenario of the portable device.

Step S708, checking whether the information of the base library list includes a base library identifier of the target base library, and if so, executing step S710; if not, step S712 is performed.

After the synchronization server determines the target base library of the portable device, the synchronization server searches whether the base library list information contains the identifier of the target base library according to base library list information corresponding to a third base library set on the portable device carried by the base library synchronization request. For example, assuming that the identifier of the target underlying library is A3, and the underlying library list information corresponding to the third underlying library set on the portable device includes the underlying library identifiers a1 and a2, it indicates that the underlying library list information does not include the underlying library identifier of the target underlying library. If the bottom library list information corresponding to the third bottom library set on the portable device includes bottom library identifiers a1, a2, and A3, it indicates that the bottom library list information includes the bottom library identifier of the target bottom library.

Step S710, updating the target base library on the portable device based on the picture sets in the respective target base libraries on the portable device and the synchronization server.

When the bottom library list information corresponding to the third bottom library set has the identifier of the target bottom library of the portable device, at this time, the synchronization server also updates the target bottom library in the portable server according to the picture set of the target bottom library in the synchronization server. Specifically, the synchronization server compares whether the number of pictures in the picture sets in the respective target base libraries on the portable device and the synchronization server is equal or not; if not, the synchronous server sends the bottom library identification of the target bottom library on the synchronous server and the picture identification set of the picture in the target bottom library on the synchronous server to the portable equipment so as to receive the picture identification set to be added, which is returned by the portable equipment based on the bottom library identification and the picture identification set; searching a picture set to be added corresponding to the picture identification set to be added in a target base library of the synchronous server; and sending the found characteristic information of the picture set to be added or each picture in the picture set to be added to the portable equipment so as to add the characteristic information of the picture set to be added or each picture in the picture set to be added to the target base library of the portable equipment, thereby realizing the timely synchronization of the target base library of the portable equipment and the corresponding target base library in the synchronization server.

In the foregoing manner, in consideration that the type of the object stored in the third base library set of the portable device may be a picture or picture feature information, if the type of the object is the picture feature information, it is described that the base library in the third base library set of the portable device stores feature information corresponding to each picture, rather than a specific picture, in this application scenario, the feature information of each picture in the picture set to be added may be sent to the portable device, so as to implement synchronization between the third base library set and the first base library set. And if the pictures stored in the third base library set of the portable equipment are stored, directly sending the picture set to be added.

Step S712, sending the target base library or the feature information corresponding to each picture in the target base library to the portable device, so as to add the target base library or the feature information corresponding to each picture in the target base library to the third base library set.

If the identification of the target base library does not exist in the base library list information, the third base library set of the portable equipment does not exist in the target base library, at the moment, the synchronization server sends the feature information corresponding to each picture in the target base library or the target base library to the portable equipment, so that the portable equipment adds the feature information corresponding to each picture in the target base library or the target base library in the third base library set, and the target base library of the portable equipment and the corresponding target base library in the synchronization server are synchronized in time. The sending of the feature information corresponding to each picture in the target base is also determined based on the type of the object stored in the third base set of the portable device, if the type of the object stored in the third base set is a picture, the target base is sent, and if the type of the object stored in the third base set is picture feature information, the feature information corresponding to each picture in the target base is sent.

According to the synchronization method, whether the target base exists in the third base set is judged by taking the base list information corresponding to the third base set on the portable equipment as a reference, and then the picture set needing to be updated in the target base or the target base is sent in a targeted manner, so that the network resource consumption can be reduced as much as possible, the synchronization operation of the third base set can be completed quickly, and the synchronization efficiency of the bases is further improved on the basis of simple and easy operation.

In one possible embodiment, a synchronization operation is also required when the portable device's underlying library is updated (e.g., pictures are added or deleted). Taking the example of adding pictures to the portable device, when adding pictures to the portable device, the portable device sends picture update information to the synchronization server, where the picture update information includes an update picture and an update base identifier corresponding to the update picture. After receiving the picture updating information sent by the portable equipment, the synchronous server analyzes the updating picture and the updating base identification corresponding to the updating picture from the picture updating information, and adds the updating picture to the first base corresponding to the updating base identification of the second base set; and the synchronous server searches the corresponding first base library in the second base library set according to the updated base library identifier, and adds the updated picture to the first base library to obtain an updated second base library set.

In the updating operation, the synchronization server further generates a second Oplog file based on the added first base library, and sends the second Oplog file to the service server through the gateway, so as to increase the updated picture in the base library corresponding to the updated base library identifier in the first base library set.

The second Oplog file includes a url field, and specifically, the synchronization server generates a base64 code based on the added updated picture in the first base library, and encodes the base64 code as the content of the url field, thereby generating the second Oplog file. After receiving the second Oplog file, the service server further analyzes the second Oplog file through the mongosharke service to obtain a base64 code in a url field in the second Oplog file; and generating an updated picture based on the base64 code, so that the updated picture is added in the base corresponding to the updated base identifier in the first base set, and the quasi-real-time synchronization of the portable device and the base corresponding to the updated base identifier of the synchronization server and the service server is realized.

Similar to the service server, the synchronization server may also read the Oplog generated by updating the second base library set through the mongoShake service to obtain a url of a newly added picture recorded in the Oplog, download the newly added picture according to the url, change the downloaded newly added picture into a corresponding base64 code, replace the url to obtain a second Oplog file, and send the second Oplog file to the ftp target of the service server through the gateway, so that the service server analyzes the second Oplog file through the mongoShake service, thereby realizing the base library quasi-real-time synchronization of the service server and the synchronization server.

In another possible implementation manner, when the base library of the portable device deletes a picture, at this time, after the synchronization server receives picture deletion information sent by the portable device, the synchronization server analyzes the deleted picture identifier and the deleted base library identifier corresponding to the deleted picture identifier from the picture deletion information, and deletes the picture corresponding to the deleted picture identifier in the second base library corresponding to the deleted base library identifier of the second base library set. After the deleting operation is completed, the synchronization server further generates a third Oplog file based on the deleted second base, and sends the third Oplog file to the business server through the gateway, so that the business server analyzes the third Oplog file through the mongosharke service, and the picture corresponding to the deleted picture identifier is deleted from the base corresponding to the deleted base identifier in the first base set, thereby realizing the timely synchronization of the portable device and the bases corresponding to the updated base identifiers of the synchronization server and the business server.

In practical application, the synchronization server may communicate with a plurality of portable devices through an ICE technology, and support the plurality of portable devices to send library information, picture information, or feature values (i.e., the feature information), and if the feature values are the feature values, the picture information may be converted into model version information of an application algorithm of the corresponding portable devices, and the model version information of the application algorithm may be reported to the synchronization server.

For convenience of understanding, the storage objects in the third library set on the portable device are taken as pictures for illustration. The synchronization method as shown in fig. 8 is a schematic diagram, and the method includes the following steps:

(1) after the portable device A, the portable device B and the portable device C are started, synchronization requests are respectively sent to a synchronization server, the base database synchronization requests sent by the portable device A and the portable device B both carry base database list information, and the base database list information comprises base database list identification and base database picture quantity.

Suppose the bottom library list information a of the portable device a is the bottom library a 2; the number of base library pictures of base library a2 is 200. Suppose the bottom library list information B of the portable device B is the bottom library a 3; the number of base library pictures of base library a3 is 300. The bottom library list information C of the portable device C is the bottom library a1, and the number of bottom libraries of the bottom library a1 is 100.

(2) And after receiving the synchronization requests of the portable equipment A, the portable equipment B and the portable equipment C, the synchronization server analyzes the base list information A, the base list information B and the base list information C.

(3) And determining the target base library of the portable device A as the base library A2 according to the service requirement of the portable device A, determining the target base library of the portable device B as the base library A3 according to the service requirement of the portable device B, and determining the target base library of the portable device C as the base library A1 and the base library A3 according to the service requirement of the portable device C.

For the portable device a, the synchronization server determines that the base library list information a includes the base library identifier of the target base library (i.e., the base library a2), and further determines whether the number of pictures in the base library a2 of the synchronization server is the same as the number of pictures in the base library a2 in the base library list information a, if the number of base library pictures in the base library a2 of the synchronization server is also 200, the two are the same, and if the number of base library pictures is the same, it is inferred that the base library a2 of the portable device and the base library a2 of the synchronization server side should be the same, and then no subsequent synchronization operation is required.

For the portable device B, the synchronization server determines that the base library list information B includes the base library identifier of the target base library (i.e., the base library A3), and then further determines whether the number of pictures in the base library A3 of the synchronization server is the same as the number of pictures in the base library A3 in the base library list information B, and if the number of base library pictures in the base library A3 of the synchronization server is 350, it indicates that the picture set of the base library A3 in the synchronization server is different from the picture set of the base library A3 in the portable device B, and the synchronization operation of the base library A3 is required.

For the portable device C, the synchronization server determines that the base library list information C includes the base library a1 in the target base library and does not include the base library A3, and further determines whether the number of pictures in the base library a1 of the synchronization server is the same as the number of pictures in the base library a1 in the base library list information C, and if the number of base library pictures in the base library a1 of the synchronization server is also 100, it indicates that the picture set of the base library a1 in the synchronization server is the same as the picture set of the base library a1 in the portable device C, and it is not necessary to synchronize the base library a 1. Since the bottom library list information C does not include the bottom library A3, and the bottom library A3 is the target bottom library of the portable device C, the synchronization server needs to issue the bottom library A3 to the portable device C.

(4) The synchronization server issues to the portable device B a picture ID set M of the full base library pictures of the base library A3 and the base library A3 identification. The full-amount library picture of the library a3 is issued to the portable device C.

(5) After receiving the identification and the set M of the bottom library A3, the portable device B searches the bottom library A3 of the device to obtain a picture ID set N of the full-quantity bottom library pictures of the bottom library A3 of the device; for picture ID in sets M and N, if the picture ID belongs to N and the picture ID belongs to N

It means that the picture is in the set N but not in the set M, and the portable device B deletes the picture of the ID. If the figure isID of a slice ∈ M and

it means that the picture is in the set M but not in the set N, and the ID of the picture is added to the set S to which the picture ID is to be added.

After the portable device B completes the comparison between the set M and the set N, the identity of the base repository a3 and the set S are sent to the synchronization server.

And after receiving the bottom library A3 sent by the synchronization server, the portable device C stores the bottom library A3.

(6) After receiving the identifier of the base repository A3 and the set S sent by the portable device B, the synchronization server searches the base repository set (e.g., service database mongoddb) of the synchronization server for the pictures corresponding to the picture IDs included in the set S to obtain a picture set T, and then sends the identifier of the base repository A3 and the picture set T to the portable device B through ICE.

(7) After receiving the identification of the base library A3 and the picture set T, the portable device B stores the picture set T in the base library A3.

It should be noted that, when the third base library set of a certain portable device is updated, including adding, modifying and deleting pictures, at this time, the update operation of the first base library set in the service server is realized through the synchronization server; after the updating operation of the service server is completed, the updating operation of the other portable equipment is realized through the synchronization server, so that the timely synchronization between each portable equipment and the service server is ensured.

On the basis of the above embodiment, the embodiment of the present invention further provides another method for synchronizing a base library, where the execution main body is a portable device installed in an external network. As shown in fig. 9, the method includes the steps of:

step S902, sending a bottom library synchronization request to a synchronization server; the synchronous server is arranged in an external network, a second bottom library set is stored in the external network, and bottom libraries in the second bottom library set are synchronous with bottom libraries in a first bottom library set of the service server in the internal network.

Specifically, when the portable device is powered on, the portable device realizes communication connection with the synchronization server through an ICE technology, and at this time, the portable device sends an inventory synchronization request to the synchronization server to update and perfect inventory information in the portable device.

Step S904, receiving the picture update information returned by the synchronization server based on the bottom library synchronization request and the second bottom library set.

After the synchronization server receives the bottom library synchronization request of the portable device, the synchronization server generates picture updating information according to the bottom library synchronization request and the second bottom library set, and sends the picture updating information to the portable device, so that the portable device updates a third bottom library set on the portable device based on the picture updating information.

Step S906, updating the third base library set on the portable device based on the picture update information.

According to the method for synchronizing the bases, provided by the embodiment of the invention, the portable device sends the base synchronization request to the synchronization server, so that the synchronization server can return the picture updating information based on the request and the second base set on the synchronization server, and the third base set on the portable device is updated based on the picture updating information because the base in the second base set is synchronized with the base in the first base set of the business server in the intranet, so that the synchronization between the first base set and the third base set can be realized.

On the basis of fig. 9, another base library synchronization method is further provided in the embodiments of the present invention, where the main execution body is a portable device, and the method mainly describes a specific process of the portable device receiving the picture update information returned by the synchronization server based on the base library synchronization request and the second base library set. As shown in fig. 10, the method comprises the steps of:

step S1002, sending a bottom library synchronization request to a synchronization server; the synchronous server is arranged in an external network, a second bottom library set is stored in the external network, bottom libraries in the second bottom library set are synchronous with bottom libraries in a first bottom library set of a service server in the internal network, and bottom library synchronous requests carry bottom library list information corresponding to a third bottom library set on the portable equipment.

Step S1004, receiving a bottom library identifier of the target bottom library and a picture identifier set of pictures in the target bottom library, which are returned by the synchronization server based on the bottom library synchronization request and the second bottom library set; in this embodiment, the base library identifier of the target base library is included in the base library list information.

Specifically, after receiving a library synchronization request, a synchronization server determines a target library corresponding to a portable device according to a service requirement, then, according to library list information corresponding to a third library set on the portable device carried by the library synchronization request, searches whether the library list information includes an identifier of the target library, and when the library list information includes the identifier of the target library and the number of library pictures in a picture set in the target library in the synchronization server is different from that in the picture set in the target library in the portable device, the synchronization server sends the library identifier of the target library and the picture identifier set of the pictures in the target library to the portable device.

In addition, if the base library identifier of the target base library is not included in the base library list information, the synchronization server sends the base library identifier of the target base library and the picture identifier set of the picture in the target base library to the portable device at the moment, so that the target base library is added to the third base library set on the portable device, and the quasi-real-time synchronization of the target base library of the portable device and the corresponding target base library in the synchronization server is realized.

Step S1006, determining a to-be-added picture identification set based on the base library identification and the picture identification set.

The specific determination manner of the to-be-added picture identifier set may refer to the description of the set S in the above embodiment, and is not described herein again.

Step S1008 returns the to-be-added picture identifier set to the synchronization server.

Step S1010, receiving a to-be-added picture set corresponding to the to-be-added picture identifier set sent by the synchronization server.

Step S1012, adding the to-be-added picture set to the target base identified by the base of the portable device, and updating the third base set on the portable device.

In one possible implementation, if the image in the base library of the portable device is updated, the portable device sends image updating information to the synchronization server, so that the synchronization server updates the second base library set based on the image updating information; the picture updating information carries the updating picture and the updating base identification corresponding to the updating picture. Optionally, the updated picture includes a modified picture and/or a newly added picture, and the corresponding updated base identifier includes a modified base identifier and/or a newly added base identifier.

In another possible implementation, if there is a picture deletion in the base library of the portable device, the portable device sends picture deletion information to the synchronization server, so that the synchronization server updates the second base library set based on the picture deletion information; the picture deleting information carries a deleted picture identifier and a deleted base identifier corresponding to the deleted picture identifier.

After the synchronization server updates the second base library set according to the updated pictures or the deleted pictures of the portable equipment, the first base library set of the service server is enabled to complete corresponding updating operation through the gateway, so that the quasi-real-time synchronization of the base library information of the portable equipment and the service server is realized.

On the basis of the above embodiment, the embodiment of the present invention further provides another method for synchronizing a base library, where the execution main body is a service server installed in an intranet. As shown in fig. 11, the method comprises the steps of:

step S1102, generate a first Oplog file based on the update operation of the first base library set of the service server.

In practical application, a business server arranged in an intranet is widely applied to the field of face recognition, meanwhile, a large number of image acquisition devices (such as cameras) can be controlled, an algorithm model subjected to deep learning is utilized, real-time data acquired by the cameras in key control areas such as railway stations, airports and bus stations are analyzed, characteristics are extracted, comparison recognition and alarm are carried out, and retrieval and identity confirmation in a human image library are realized in a mode of searching images by images, so that a first bottom library set of the business server is a bottom library source of portable equipment, and the realization of quasi-real-time synchronization of bottom library information of the portable equipment and the business server has important practical significance.

Step S1104, issuing a first Oplog file to the synchronization server through the gateway, so that the synchronization server updates a second bottom library set in the external network by applying the first Oplog file, and in response to a bottom library synchronization request of the portable device, updating a third bottom library set on the portable device based on the updated second bottom library set; the gateway is a gateway used for isolating an internal network and an external network, and the synchronous server is arranged on the external network.

In the method for synchronizing the bases provided by the embodiment of the invention, when the first base set has an updating operation, the service server generates a first Oplog file, and sends the first Oplog file to the synchronization server through the gateway, so that the synchronization server updates the second base set in the external network by applying the first Oplog file, responds to the base synchronization request of the portable device, and updates the third base set on the portable device based on the updated second base set.

In one possible implementation, when a target picture is added or modified in the first bottom library set of the service server, a base64 encoding of the target picture is generated, and the base64 encoding is used as the content of a url field to generate a first Oplog file, where the first Oplog file contains the url field, so that the service server parses the first Oplog file through the mongosake service to obtain a base64 encoding in the url field of the first Oplog file, and obtains the target picture based on the base64 encoding.

In one possible implementation, when the service server receives the second Oplog file sent by the synchronization server through the gateway; the second Oplog file is generated by the synchronization server based on the updated picture of the portable equipment; and updating the target base library of the first base library set based on the second Oplog file, so that the base library information of the portable equipment and the service server is synchronized in quasi-real time. In addition, when the business server receives a third Oplog file sent by the synchronous server through the gateway; here, the third Oplog file is generated by the synchronization server based on the deleted pictures of the portable device; and deleting the deleted pictures in the target base of the first base set based on the third Oplog file so as to realize the quasi-real-time synchronization of the base information of the portable equipment and the service server.

Corresponding to the bottom library synchronization method shown in fig. 2, an embodiment of the present invention further provides a bottom library synchronization apparatus, which is applied to a synchronization server installed in an external network. As shown in fig. 12, the apparatus includes a first receiving module 1202, a first updating module 1204 and a second updating module 1206 connected in sequence, wherein the functions of the modules are as follows:

A second updating module 1206 is configured to update a third underlying library set on the portable device based on the updated second underlying library set when responding to an underlying library synchronization request of the portable device.

The synchronization device of the base library provided in the embodiment of the present invention is configured such that a synchronization server disposed in an external network receives a first Oplog file issued by a service server through a gateway, where the first Oplog file is a file generated by the service server based on an update operation of a first base library set in an internal network, the synchronization server updates a second base library set in the external network by using the first Oplog file, so as to implement a timely synchronization between the first base library set in the internal network and the second base library set in the external network, and the synchronization server responds to a base library synchronization request of a portable device and updates a third base library set on the portable device based on the updated second base library set, so as to implement a synchronization between the third base library set and the second base library set in the external network, which is equivalent to implement a synchronization between the third base library set on the portable device and the first base library set on the internal network service server, the synchronization mode can quickly realize the synchronization of the base libraries in the mode that the portable equipment sends the synchronization request without configuring additional storage hardware (such as a U disk and the like) and a third-party storage device on the portable equipment, thereby relieving the problem of lag in updating the base libraries of the portable equipment, simplifying the updating operation of the portable equipment and being convenient for popularization and implementation.

In one possible implementation, the url field of the first Oplog file encodes a base64 of a target picture modified or added by the service server, and the first updating module 1204 is further configured to: analyzing the first Oplog file to obtain a target picture; determining whether the target picture is a newly added picture according to the identification of the target picture; if yes, adding a target picture in a second bottom library set of the external network; and if not, replacing the corresponding picture identified in the second base library set by the application target picture.
