[0001] The present invention relates to the field of big data technology, and in particular to a latitude and longitude correction method, device, electronic device and storage medium. Background Art

[0002] The same coordinate location expressed in different coordinate systems produces different longitudes and latitudes. The same longitudes and latitudes expressed in different coordinate systems produce different locations. If the coordinate system to which the longitudes and latitudes correspond cannot be determined, the value of the information is greatly reduced. Therefore, for longitudes and latitudes parsed and restored from massive amounts of network data, it is necessary to determine the coordinate system and generate corrected longitudes and latitudes to obtain complete and accurate information.

[0003] In the existing technology, when performing latitude and longitude correction for terminal applications, manual analysis and annotation are often performed, and the latitude and longitude positions are used for latitude and longitude correction. This method is not only inefficient, but also prone to large errors during correction.

[0032] The acquisition, storage, use, and processing of data in this application's technical solution comply with relevant national laws and regulations.

[0033] In one embodiment, Figure 1 A flowchart of a latitude and longitude correction method provided in one embodiment of the present invention is applicable to situations when latitude and longitude are corrected. The method can be performed by a latitude and longitude correction device, which can be implemented in the form of hardware and / or software. The latitude and longitude correction device can be configured in an electronic device.

[0034] like Figure 1 As shown, the method is applied to the proxy server, and the specific steps include:

[0035] S110 : Determine a target network account with a trusted address in the fixed network data message based on a preset initial trusted application identifier and an original coordinate system corresponding to the preset initial trusted application identifier.

[0036] The preset initial trusted application identifier refers to the determined initial trusted application identifier. There are generally multiple preset initial trusted application identifiers, and the application identifier refers to the identifier corresponding to a software application on a terminal device. A fixed-line data packet refers to a data traffic packet generated under a network account, and this data traffic packet can be referred to as a data packet. The target network account, also known as an asymmetric data user loop, can be understood as a network broadband account. The number of target network accounts can be one or more. In this embodiment, each network broadband account can correspond to multiple terminal devices, and each terminal device can correspond to multiple application identifiers.

[0037] In this embodiment, the fixed-line data message corresponding to the network account is parsed and restored to extract the network account, application identifier, and corresponding original coordinate system from the restored fixed-line data message. A preset initial trusted application identifier and its corresponding original coordinate system that matches the address information are determined from the application identifier and the corresponding original coordinate system. Based on the preset initial trusted application identifier and its corresponding original coordinate system, at least one target network account with a trusted address is determined. In some embodiments, the target network account can generate three coordinate systems using a preset coordinate system conversion algorithm. For example, if the longitude and latitude coordinate system is WGS84, the longitude and latitude of the other two coordinate systems need to be generated using the WGS84->GCJ02 conversion algorithm and the WGS84->BD09 conversion algorithm.

[0038] S120: Obtain an application identifier of a target network account with a coordinate system to be confirmed.

[0039] The coordinate system to be confirmed can be understood as a coordinate system waiting for confirmation. The coordinate system to be confirmed can include one or more application identifiers related to the coordinate system to be confirmed.

[0040] In this embodiment, the coordinate centroid corresponding to the application identifier can be determined based on the preset clustering rules and the number of location points corresponding to at least one identical application identifier under each target network account, and the application identifier of the coordinate system to be confirmed can be determined based on the proportion of the coordinate centroid; in some embodiments, the location points corresponding to at least one identical application identifier under each target network account can be determined, and when the location points can be clustered, the location points with the same application identifier under the target network account are extracted, and the location coordinate point clusters of the location points are generated according to the preset clustering rules, and the coordinate centroid of the location point clusters are determined, and the application identifier of the coordinate system to be confirmed can be determined based on the proportion of the coordinate centroid.

[0041] S130 : Determine the target reference coordinate system according to the number of coordinate systems to be confirmed under the application identifier.

[0042] The number of coordinate systems can be represented by the percentage of coordinate systems or directly by the number, which is not limited in this embodiment. The target reference coordinate system can be understood as the correction coordinate system corresponding to the application identifier of each coordinate system to be confirmed.

[0043] In this embodiment, the number of target network accounts can be counted by determining at least one target network account corresponding to each application identifier of the coordinate system to be confirmed. For each target network account, at least one coordinate system corresponding to each target network account is determined. Based on the coordinate centroid corresponding to the at least one coordinate system and the application identifier, the number of coordinate systems of the coordinate system to be confirmed under the application identifier is determined, and the coordinate system whose number of coordinate systems reaches a preset percentage threshold is used as the target reference coordinate system. In some embodiments, the number of coordinate systems can include the number of coordinate systems corresponding to multiple coordinate systems, including the number of coordinate systems corresponding to the Baidu coordinate system, the number of coordinate systems corresponding to the Earth coordinate system, and the number of coordinate systems corresponding to the Mars coordinate system, so as to select the coordinate system with the largest number of coordinate systems from the number of coordinate systems corresponding to the multiple coordinate systems.

[0044] S140: Correct the coordinate system to be confirmed under the target network account based on the target reference coordinate system.

[0045] In this embodiment, when the target reference coordinate system is determined, the coordinate system of each coordinate system to be confirmed under the target network account can be calibrated according to the determined target reference coordinate system.

[0046] The technical solution of the embodiment of the present invention can automatically obtain and correct longitude and latitude by obtaining an application identifier with a coordinate system to be confirmed under a target network account with a trusted address, determining the target reference coordinate system based on the number of coordinate systems to be confirmed and performing correction, thereby improving efficiency and reducing correction errors.

[0047] In one embodiment, Figure 2 A flowchart of another latitude and longitude correction method provided for an embodiment of the present invention. Based on the above embodiments, this embodiment further refines the method of determining a target network account with a trusted address in a fixed-line data message based on a preset initial trusted application identifier and the original coordinate system corresponding to the preset initial trusted application identifier, obtaining an application identifier with a coordinate system to be confirmed under the target network account, and determining a target reference coordinate system according to the number of coordinate systems to be confirmed under the application identifier.

[0048] like Figure 2 As shown, the latitude and longitude correction method in this embodiment may specifically include the following steps:

[0049] S210: Obtain fixed network data packets and parse and restore the fixed network data packets.

[0050] In this embodiment, fixed-line data packets can be mirrored through a traffic diversion device. This requires mirroring all fixed-line data packets carrying longitude and latitude information, and then parsing and restoring the corresponding protocol stack. For example, fixed-line data packets contain data information from all networks and can be data packets corresponding to a home router, data packets corresponding to a shopping mall router, or a combination of data packets corresponding to both home and shopping mall routers.

[0051] S220: Extract the network account, application identifier, and their corresponding original coordinate system from the restored fixed network data message.

[0052] In this embodiment, the fixed-line data message is parsed and restored to extract the network account, application identifier, and its corresponding original coordinate system. In this embodiment, the application identifier is the identifier corresponding to a software application on the terminal. Each application identifier corresponds to an original longitude and latitude coordinate system. The original coordinate systems corresponding to different application identifiers may be the same or different. It can be understood that different application identifiers may be in the same coordinate system or in different coordinate systems.

[0053] It should be noted that each application identifier has a corresponding classification principle. For example, an application identifier under the Hypertext Transfer Protocol (HTTP) protocol is represented by a uniform resource locator + host + operating system type. For non-HTTP protocol application identifiers, the server Internet Protocol address + server port is used.

[0054] S230: Determine a preset initial trusted application identifier and its corresponding original coordinate system whose address information matches the application identifier and its corresponding original coordinate system.

[0055] In this embodiment, a preset initial trusted application identifier and its corresponding original coordinate system can be obtained by screening from the application identifier and its corresponding original coordinate system. Specifically, the original longitude and latitude corresponding to each application identifier can be determined, the original longitude and latitude can be converted into coordinates and at least one first address information corresponding to the conversion can be determined, the second address information of each application identifier for packet capture analysis at a preset fixed position can be obtained, at least one first address information can be compared with the second address information, and the successfully compared address information can be used as the preset initial trusted application identifier and its corresponding original coordinate system, so that the preset initial trusted application identifier and its corresponding original coordinate system and the heuristic learning algorithm can be used to inspire more application identifiers. It can be understood that the initial trusted application identifier and the coordinate system are the basis of the heuristic learning algorithm, and a percentage of confidence needs to be guaranteed to inspire more application identifiers.

[0056] S240: Determine at least one target network account with a trusted address based on a preset initial trusted application identifier and its corresponding original coordinate system.

[0057] In this embodiment, based on the obtained initial trusted application identifier and its corresponding original coordinate system, it can be understood that the location information corresponding to the initial trusted application identifier is obtained. If the terminal user uses the initial trusted application identifier, and since the initial trusted application identifier has a corresponding original coordinate system, at least one target network account with a trusted address can be obtained, and at least one target network account with a trusted address can be converted into three coordinate systems through a preset coordinate conversion algorithm. The three coordinate systems can include the Earth coordinate system, the Mars coordinate system and the Baidu coordinate system.

[0058] S250: Extract location points with the same application identifier under the target network account.

[0059] The location point may also be referred to as a coordinate point of an application identifier. Generally, there are multiple location points.

[0060] In this embodiment, for each target network account, the number of location points corresponding to at least one identical application identifier under the target network account is determined. The number of location points corresponding to the application identifier can be used to determine whether the location points under the application identifier participate in the cluster analysis. For example, if a target user terminal under a home broadband account has 5 coordinate points corresponding to 10 application identifiers, and a target user terminal under a shopping mall broadband account has 1000 coordinate points corresponding to the same 10 application identifiers, then the 1000 coordinate points can be determined to participate in the cluster analysis.

[0061] S260: Generate a location coordinate point cluster of the location point according to a preset clustering rule, and determine the coordinate centroid of the location point cluster.

[0062] The preset clustering rule refers to a rule for clustering location points with the same application identifier. The preset clustering rule can be performed by a clustering algorithm, for example, a density-based spatial clustering algorithm (Density-Based Spatial Clustering of Applications with Noise, DBSCAN), to perform cluster analysis.

[0063] In this embodiment, when the number of location points with the same application identifier under the target network account is greater than the preset proportion threshold, the application identifier corresponding to the location point participates in the clustering analysis, and the minimum clustering range and the adjacent location point threshold are given according to the preset clustering rules. All location points are clustered into clusters to generate location coordinate point clusters of the location points, and the coordinate centroid of the location point cluster is determined.

[0064] S270: Determine the application identifier of the coordinate system to be confirmed based on the proportion of the coordinate centroid.

[0065] In this embodiment, the number of application identifiers of all determined coordinate centroids under each target network account is counted, thereby determining the proportion of the coordinate centroids, and then determining the application identifier of the coordinate system to be confirmed based on the proportion.

[0066] In one embodiment, determining the application identifier of the coordinate system to be confirmed based on the proportion of the coordinate centroid includes:

[0067] Count the number of application identifiers with determined coordinate centroids under each target network account;

[0068] Determine the proportion of coordinate centroids based on the number of application identifiers;

[0069] If the proportion of the coordinate centroid does not exceed the second preset proportion threshold, the application identification of the coordinate system to be confirmed is skipped;

[0070] When the proportion of the coordinate centroid exceeds the second preset proportion threshold, the application identifier is used as the application identifier of the coordinate system to be confirmed, and the application identifier of the coordinate system to be confirmed is added to the application identifier list to be confirmed.

[0071] Among them, the second preset proportion threshold refers to the proportion threshold corresponding to the coordinate centroid. The preset proportion threshold can be set accordingly based on experience, or it can be set accordingly in other ways. This embodiment does not limit it here. Of course, when setting the second preset proportion threshold, the proportion threshold should be set as high as possible. For example, the second preset proportion threshold is set to more than 90%, so that the application identification of the coordinate system to be confirmed can be more accurate.

[0072] In this embodiment, the number of application identifiers for which coordinate centroids have been determined under each target network account is counted, and the proportion of coordinate centroids is determined based on the number of each application identifier. If the proportion of coordinate centroids does not exceed a second preset proportion threshold, the application identifier for the coordinate system to be confirmed is skipped; if the proportion of coordinate centroids exceeds the second preset proportion threshold, the application identifier is used as the application identifier for the coordinate system to be confirmed and is added to the list of application identifiers to be confirmed. It should be noted that for application identifiers for which the centroid can be calculated, the application identifier is used as the index and counted by one. This can be understood as calculating the centroid for multiple application identifiers under each target network account, which increases the credibility.

[0073] In one embodiment, before generating a location coordinate point cluster of the location point according to a preset clustering rule and determining the coordinate centroid of the location point cluster, the method further includes:

[0074] Determine the location points corresponding to at least one identical application identifier under each network account;

[0075] If the location point is less than or equal to the first preset proportion threshold, the application identifier corresponding to the location point does not participate in the cluster analysis;

[0076] When the number of location points is greater than the first preset proportion threshold, the application identifier corresponding to the location point participates in the cluster analysis.

[0077] Among them, the first preset proportion threshold refers to the minimum proportion corresponding to the location point under the application identifier. For example, the first preset proportion threshold is 5%, that is, when the location point is less than or equal to 5, the application identifier corresponding to the location point does not participate in the cluster analysis.

[0078] In this embodiment, before generating a location coordinate point cluster of the location point according to the preset clustering rules and determining the coordinate centroid of the location point cluster, it also includes: determining the location points corresponding to at least one identical application identifier under each target network account. When the number of location points is less than or equal to the first preset proportion threshold, the application identifier corresponding to the location point does not participate in the cluster analysis. When the number of location points is greater than the first preset proportion threshold, the application identifier corresponding to the location point participates in the cluster analysis.

[0079] S280: Determine that each application identifier in the list of application identifiers to be confirmed corresponds to at least one target network account, and count the number of target network accounts corresponding to each application identifier.

[0080] In this embodiment, the application identification list of the coordinate system to be confirmed is traversed, and for each application identification, at least one target network account corresponding to the application identification is determined, and the number of target network accounts corresponding to each application identification is counted.

[0081] S290: Determine whether the number of target network accounts exceeds a preset threshold. If not, execute S2100; if so, execute S2110.

[0082] In this embodiment, if the number of target network accounts does not exceed the preset number threshold, the application identification is skipped; if the number of target network accounts exceeds the preset number threshold, at least one coordinate system corresponding to each target network account is determined, and the number of coordinate systems to be confirmed is determined based on the coordinate centroid corresponding to at least one coordinate system and the application identification, and the coordinate system whose number of coordinate systems reaches the third preset proportion threshold is used as the target reference coordinate system.

[0083] S2100: Skip application identification.

[0084] In this embodiment, if the number of target network accounts does not exceed a preset threshold, the application identifier is skipped. This can be understood as excluding the application identifier. The preset threshold can be set based on experience or manually, and this embodiment does not limit this. For example, the preset threshold can be set to 5, 10, etc.

[0085] S2110. Determine at least one coordinate system corresponding to each target network account, determine the number of coordinate systems to be confirmed based on the coordinate centroid corresponding to the at least one coordinate system and the application identifier, and use the coordinate system whose number of coordinate systems reaches a third preset proportion threshold as the target reference coordinate system.

[0086] Among them, at least one coordinate system includes the Earth coordinate system, the Mars coordinate system and the Baidu coordinate system.

[0087] The third preset ratio threshold refers to the ratio threshold of the number of coordinate systems corresponding to a certain coordinate system. The third preset ratio threshold is generally set relatively large to make the corrected coordinate system more accurate. Exemplarily, the third preset ratio threshold is greater than 90%.

[0088] In this embodiment, when the number of target network accounts exceeds a preset number threshold, at least one coordinate system corresponding to each target network account is determined, and the number of coordinate systems to be confirmed under the application identifier is determined based on the coordinate centroid corresponding to at least one coordinate system and the application identifier, and the coordinate system whose number of coordinate systems reaches the third preset proportion threshold is used as the target reference coordinate system. Specifically, for the target network account with the covered trusted address, the distance between the coordinate centroid under the application identifier and the three coordinate systems corresponding to the target network account (Earth coordinate system, Mars coordinate system and Baidu coordinate system) is calculated respectively. If the distance is within the maximum allowable offset range, the coordinate system count under the application identifier is increased by one. Among them, the three coordinate system addresses of the target network account are the Earth coordinate system, the Mars coordinate system and the Baidu coordinate system.

[0089] In one embodiment, determining the number of coordinate systems to be confirmed under the application identifier based on the coordinate centroid corresponding to at least one coordinate system and the application identifier, and using the coordinate system whose number reaches a third preset proportion threshold as the target reference coordinate system includes:

[0090] Determine the distance between the coordinate centroid corresponding to the application identifier and the Earth coordinate system, Mars coordinate system, and Baidu coordinate system corresponding to each target network account using the Euclidean distance formula;

[0091] Determine whether the coordinate centroid corresponding to the application identifier and the Earth coordinate system, the Mars coordinate system, and the Baidu coordinate system corresponding to each target network account are within a preset offset range;

[0092] If the distance is within the preset offset range, the coordinate system corresponding to the application identifier within the preset offset range is determined and the corresponding coordinate system is incremented by one, and the distance determination operation is returned until the coordinate centroid corresponding to all application identifiers is determined.

[0093] The quantitative proportion of the three coordinate systems corresponding to the application identification, namely the Earth coordinate system, the Mars coordinate system and the Baidu coordinate system, is counted. When the quantitative proportion reaches the preset proportion threshold, the coordinate system that reaches the preset proportion threshold is considered to be the target reference coordinate system of the application identification.

[0094] The preset offset range refers to the maximum offset range allowed by the distance, and the preset offset range can be set accordingly based on experience or manually, and is not limited in this embodiment. For example, the preset offset range is 200m, etc.

[0095] In the embodiment, the distance between the coordinate centroid corresponding to the application identifier and the earth coordinate system, the Mars coordinate system and the Baidu coordinate system corresponding to each target network account is determined according to the Euclidean distance formula, whether the coordinate centroid corresponding to the application identifier and the earth coordinate system, the Mars coordinate system and the Baidu coordinate system corresponding to each target network account are respectively within the preset offset range is judged, if the distance is within the preset offset range, it is determined that the coordinate system corresponding to the application identifier is within the preset offset range and the add-one operation of the corresponding coordinate system is performed, the distance judgment operation is returned, until the coordinate centroid corresponding to all application identifiers is judged, the number proportion of the earth coordinate system, the Mars coordinate system and the Baidu coordinate system corresponding to the application identifier is counted, and in the case that the number proportion reaches the preset proportion threshold, it is considered that the coordinate system reaching the preset proportion threshold is the target reference coordinate system of the application identifier.

[0096] For example, in the case that the preset offset range is 200m, the distance between the coordinate centroid corresponding to the application identifier and the earth coordinate system, the Mars coordinate system and the Baidu coordinate system corresponding to each target network account is calculated, and the distance calculated by the earth coordinate system and the Mars coordinate system may be less than 200. For the earth coordinate system and the Mars coordinate system under the application identifier, the count is added by one. If the Baidu coordinate system is within the maximum offset 200m, the Baidu coordinate system is added by one. Finally, according to the corresponding coordinate system number statistics value under the application identifier, the correction coordinate system of the terminal user is determined, for example, finally, under the application identifier, 100 target network accounts are corresponding, 98 of which are corresponding to the Mars coordinate system, and 2 of which are corresponding to the earth coordinate system. The final target reference coordinate system is the Mars coordinate system.

[0097] S2120, correcting the to-be-confirmed coordinate system under the target network account based on the target reference coordinate system.

[0098] The above technical solution of the embodiment of the present invention can quickly and accurately find the location points that can be clustered and find the coordinate system corresponding to the application representation that needs to be corrected by extracting the location points with the same application identifier under the target network account, generating the location coordinate point cluster according to the preset clustering rules, determining the coordinate centroid of the location point cluster, and determining the application identifier of the coordinate system to be confirmed based on the proportion of the coordinate centroid. It is also possible to determine the location points that can be clustered and find the coordinate system corresponding to the application representation that needs to be corrected. It is also possible to determine at least one target network account corresponding to each application identifier in the list of application identifiers to be confirmed, and count the number of target network accounts corresponding to each application identifier. If the number of target network accounts does not exceed the preset number threshold, the application identifier is skipped. If the number of target network accounts exceeds the preset number threshold, it is possible to determine at least one coordinate system corresponding to each target network account, determine the number of coordinate systems of the coordinate system to be confirmed under the application identifier based on the coordinate centroid corresponding to the at least one coordinate system and the application identifier, and use the coordinate system whose number of coordinate systems reaches the third preset proportion threshold as the target reference coordinate system. It is also possible to further realize automatic acquisition and correction of longitude and latitude, improve efficiency and reduce correction errors.

[0099] In one embodiment, to facilitate a better understanding of the latitude and longitude correction method, this embodiment can be used as a preferred embodiment to further illustrate the latitude and longitude correction method. Figure 3 A diagram illustrating the structure of longitude and latitude calibration according to one embodiment of the present invention. This embodiment uses as an example a first preset percentage threshold of 10%, a second preset percentage threshold of 90%, a preset number threshold corresponding to the number of network accounts of 10, and a third preset percentage threshold of 90%. The calibration coordinate system in this embodiment is the target reference coordinate system in the aforementioned embodiment.

[0100] In this embodiment, a high-performance server for automatically obtaining corrected longitude and latitude is required, a refined traffic diversion device currently in operation on the existing network, and a database server. Fixed-line data packets need to be mirrored through the diversion device and the mirrored data output to the server for automatically obtaining corrected longitude and latitude. The implementation process requires the following steps:

[0101] a1. Original data diversion

[0102] In this embodiment, the refined traffic distribution equipment is used to distribute data on the router link, and all fixed network data packets carrying longitude and latitude information need to be mirrored. The filtering of fixed network data packets containing longitude and latitude information can be decentralized through regular rules.

[0103] a2. Automatically obtain the corrected longitude and latitude server

[0104] In this embodiment, a data parsing program and a coordinate system learning program are installed on the server, and the parsed data includes some structured data of the application latitude and longitude coordinate system.

[0105] a3. Database server setup

[0106] In this embodiment, a database server is built based on the data size. If the data size is small, a relational database management system can be used; if the data size is large, a distributed storage system needs to be built. a4. Start the data analysis program and the coordinate system learning program.

[0107] Parse and restore the fixed network data message to extract the network account, application identifier and the corresponding original coordinate system. Figure 4 A flowchart of another latitude and longitude correction method provided in one embodiment of the present invention. The latitude and longitude correction method includes the following steps:

[0108] S410: Parse and restore the fixed network data message to extract the network account, application identifier, and corresponding original coordinate system.

[0109] S420: Determine a preset initial trusted application identifier and its corresponding original coordinate system whose address information matches the application identifier and its corresponding original coordinate system.

[0110] In this embodiment, the preset initial trusted application identifier and its corresponding original coordinate system include at least three types of application identifiers and corresponding coordinate systems.

[0111] S430. Based on the preset initial trusted application identifier and its corresponding original coordinate system, if the latitude and longitude corresponding to the preset initial trusted application identifier are generated under the network account, the network account of the trusted address is obtained according to the original coordinate system obtained under the preset initial trusted application identifier.

[0112] S440. Obtain an application identifier of a coordinate system to be confirmed under a network account of each trusted address: perform cluster analysis on location points obtained under at least one identical application identifier under a network account of each trusted address to determine the application identifier of the coordinate system to be confirmed.

[0113] In this embodiment, if the number of location points associated with an application identifier is less than or equal to 10, the application identifier is not included in the cluster analysis because the corresponding location point samples are too small. If the number of location points associated with an application identifier is greater than 10, the location points associated with the application identifier are clustered using a density-based clustering algorithm. If at least 90% of the location points participating in the clustering for the application identifier can be clustered into a single cluster, the application identifier is considered credible, and the coordinate centroid of the location point cluster is calculated. Otherwise, the coordinate centroid of the location point cluster is not calculated.

[0114] In the embodiment, for the application identifier capable of calculating the coordinate centroid of the position point cluster, the count is incremented by one. When the position point cluster analysis under all network application identifiers is completed, the proportion of the number of networks capable of obtaining the coordinate centroid under the application identifier is calculated. If more than 90% of the networks under the application identifier can be clustered and the coordinate centroid is calculated, the application identifier is added to the application identifier list of the to-be-confirmed coordinate system.

[0116] In the embodiment, the application identifier list of the to-be-confirmed coordinate system is traversed, and each application identifier is counted as follows: 1) the network accounts with trusted addresses covered are searched, if the number of network accounts exceeds 10, the processing is continued; otherwise, the application identifier is skipped; 2) for the network accounts with trusted addresses covered, the distance between the coordinate centroid under the application identifier and the corresponding three coordinate systems under the network account is calculated according to the Euclidean distance formula, if the distance is within the allowed maximum offset range (for example, 200m), the coordinate system count under the application identifier is incremented by one. When all is completed, if the network account proportion of a certain coordinate system is more than 90%, the coordinate system of the application identifier is determined, and the trusted application identifier and its coordinate system are added to the trusted application identifier list.
