Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

However, since the data update package includes the update data and the original data, it is necessary to process a large amount of data of the high-precision map regardless of the process of generating the data update package by the development side or the process of updating based on the data update package by the client side. In the processing process, the original data of the non-updated data is required to be repeatedly processed, so that the overall processing efficiency is reduced, and the failure of the high-precision map is not facilitated.

In order to solve the problems, the present disclosure provides a data processing method, device, electronic device and storage medium for a high-precision map, where a data processing device for a high-precision map including a database is established between a request end and a client end, and an update request for a high-precision map initiated by the client end is received, where the update request includes a target version of the high-precision map, and target data matched with the target version is determined according to a data version of each data in the database; sending the downloading information in the data attribute of the target data to a client side, so that the client side can download the target data according to the downloading information and update the high-precision map; the downloaded information is generated when the target data is stored and is stored in the corresponding data attribute in a correlated manner, and the uploaded or downloaded updated data does not include original data any more, so that the data processing amount required by updating is small, and the data processing efficiency of the map is effectively improved.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture based on which the present disclosure is based, and the network architecture shown in fig. 1 may specifically include an initiator 1, a high-precision map data processing apparatus 2, and a client 3.

The initiating terminal 1 and the client terminal 3 may be hardware devices such as a mobile phone, a desktop computer, an intelligent home device, and a tablet computer. Specifically, the initiator 1 may be a data issuer of the high-precision map, which may generate data of the high-precision map based on actual needs and upload the data to a database in the high-precision map data processing apparatus. The client 3 may be a user of a high-definition map, which is generally installed in a vehicle or a mobile device, and may perform a driving task based on the high-definition map, and may update the high-definition map thereof with data of the high-definition map downloaded from the database of the high-definition map data processing device 2.

The high-precision map data processing device 2 is hardware or software capable of interacting with multiple parties through a network, and is provided with a database and can be used for executing a data processing method of the high-precision map in each example described below so as to process and transmit the received update data.

In the network architecture shown in fig. 1, when the high-precision map data processing apparatus 1 is hardware, it may include a cloud server with an arithmetic function; when the high-precision map data processing apparatus 1 is software, it can be installed in an electronic device having an arithmetic function, including, but not limited to, a laptop computer, a desktop computer, and the like.

That is to say, the data processing method of the high-precision map based on the present disclosure can be based on the embodiment shown in fig. 1, and is widely applicable to the application scenario involving the high-precision map.

In a first aspect, referring to fig. 2, fig. 2 is a schematic flowchart of a data processing method for a high-precision map according to an embodiment of the present disclosure. The data processing method of the high-precision map provided by the embodiment of the disclosure comprises the following steps:

step 101, receiving an update request of a high-precision map initiated by a client, wherein the update request comprises a target version of the high-precision map.

And step 102, determining target data matched with the target version according to the data version of each data in the database.

103, sending download information in the data attribute of the target data to a client, so that the client can download the target data according to the download information and update the high-precision map; and the downloading information is generated when the target data is stored and is stored in the corresponding data attribute in an associated manner.

The execution subject of the processing method provided in this example is the aforementioned high-precision map data processing apparatus, which can interact with each other via a network.

In the embodiment provided by the present disclosure, steps 101 to 103 are processing manners of the data processing apparatus after receiving the update request initiated by the client.

Specifically, when a client wishes to update its own high-precision map, it initiates an update request to the data processing apparatus, in which its own requirements, i.e., target version, are shown.

That is, unlike the prior art, in order to reduce the amount of data received per update and avoid the client from reprocessing data that has been processed during a previous update, in embodiments provided by the present disclosure, the client may identify a target version of the demand in the update request. Of course, the target version may be the current latest version or the historical version, which is determined based on the user requirements of the client, and this disclosure does not limit this.

Then, the data processing device determines target data matched with the target version based on the data version corresponding to each data stored in the database, and sends download information in the data attribute of the target data to the client, so that the client can download the target data according to the download information and update the high-precision map; and the downloading information is generated when the target data is stored and is stored in the corresponding data attribute in an associated mode.

Optionally, in order to ensure data security, problems of data packet loss, hijacking, tampering and the like in the data transmission process are avoided. The download information provided by the data attribute also comprises a data code of the target data and a download address of the target data. Specifically, the data code and the download address of the target data can be sent to the client, so that the client can obtain the data content of the target data according to the download address, perform data verification on the obtained data content of the target data according to the database, and update the high-precision map after the verification is passed.

The data code in the download information is used for performing data verification on target data by using the data code after the target data is downloaded and obtained by the client, and updating is performed after the verification is passed, and the download address can be generated in real time.

When the data processing device is executed, the data code and the download address in the download information can be sent to the client, after the client acquires the target data according to the download address, the data code in the data attribute of the acquired target data is compared with the data code in the download information, and when the data code and the data code are consistent, the data processing device is updated based on the target data. The specific generation and comparison of the data codes can be based on the existing technologies of data signature, data encryption and the like, and the present disclosure does not limit this.

In the data processing method for the high-precision map provided by the embodiment, an update request of the high-precision map, which is initiated by a client, is received, where the update request includes a target version of the high-precision map; determining target data matched with the target version according to the data version of each data in the database; sending download information in the data attribute of the target data to a client side, so that the client side can download the target data according to the download information and update the high-precision map; and the downloading information is generated and stored in corresponding data attributes in an associated manner when the target data is stored. By adopting the mode, the automatic processing of receiving and sending the high-precision map data can be effectively realized, the data volume is relatively small during processing, and the processing efficiency is improved.

Referring to fig. 3, fig. 3 is a schematic flowchart of another data processing method for a high-precision map according to an embodiment of the present disclosure. The data processing method of the high-precision map provided by the embodiment of the disclosure comprises the following steps:

step 201, receiving update data of a high-precision map uploaded by a request end; the update data includes data content and metadata.

Step 202, storing the data content in a database and generating corresponding download information, and updating the data attribute and the data version of the updated data in the database according to the metadata and the download information.

Step 203, receiving an update request of the high-precision map initiated by the client, wherein the update request comprises a target version of the high-precision map.

And 204, determining target data matched with the target version according to the data version of each data in the database.

Step 205, sending the download information in the data attribute of the target data to a client, so that the client can download the target data according to the download information and update the high-precision map; and the downloading information is generated when the target data is stored and is stored in the corresponding data attribute in an associated manner.

Different from the foregoing embodiment, the present embodiment further includes a process of receiving and storing the update data of the high-precision map uploaded by the request end.

For the present embodiment, in step 201, upon receiving the update data of the high-precision map uploaded to the database by the request end, the database of the data processing apparatus may receive the update data of the high-precision map requested to be uploaded by the developer. Wherein, the update data should be data in a preset format, such as data in a data exchange format (Map Info, abbreviated as MIF); dynamic traffic information data is also included; data for other needs may also be included.

In an optional embodiment, in order to further improve the automation degree, a compiling module may be disposed in the Data processing apparatus, so that after receiving the updated Data, the Data processing apparatus compiles the updated Data into Data of a Navigation Data Standard (NDS) through the compiling module, so as to be used by a back end, that is, a client.

In addition, in step 202, in order to improve data storage efficiency, update efficiency and distribution efficiency, the database provided in the embodiment of the present disclosure may adopt a Catalog data architecture manner, in which data stored in the database is to be composed of data content and data attributes, where the data attributes are used to represent architecture information of the data in the database, for example, the data is characterized by architecture identification of the data in the database architecture.

For example, fig. 4 is a schematic data architecture diagram of a data processing method for a high-precision map provided by an embodiment of the present disclosure, and as shown in fig. 4, Catalog is an organization manner of data, and generally stores all data whose contents are a certain single data version.

Corresponding to fig. 4, the architectural drawing layers, i.e. layers in the drawing, different drawing layers represent different object types, such as topographic data, signage data, etc. in a high-precision map, and each architectural drawing layer is relatively independent, and data of any architectural drawing layer is updated, so that data of other architectural drawing layers will not be affected. And all layer data will constitute a high-precision map, i.e. data of all object types will constitute a high-precision map.

For each architectural layer, there are multiple architectural views, i.e. partitions in the map. Wherein each architectural view corresponds to a different geographic region. That is, in the architecture diagram, data of a certain geographic area under the object type corresponding to the architecture diagram layer to which the architecture diagram belongs is stored; the geographic areas of the plurality of architectural views under the same architectural view layer may not overlap or may partially overlap. Illustratively, Partition uses the size of the NDS thirteen-level grid as the size of the map frame.

Meanwhile, as for data in the database, the content represented by the data and the stored architecture position are represented by layer identification of the architecture layer and map identification of the architecture map, and the layer identification and the map identification are stored in the database as data attributes of the data. When the database stores data, whether the data is the same data is determined by whether the architecture identifier and the map sheet identifier are the same, that is, the data corresponds to a map layer identifier-map sheet identifier shown in fig. 4, and the map layer identifier-map sheet identifier of different data are different.

In other words, data in the Catalog data schema will be stored according to the composition of the schema map layer and the schema map sheet. In order to associate the data content and the data attribute of any data in the database, the data content and the data attribute can be characterized by using the same over-architecture identifier. As for the same data, the naming of its data content may be as 0_1_29_557467385_2.BLOB and the naming of its data attributes may be as 0_1_29_557467385_2. json. In the above naming, 55747385 is the map sheet identifier, and 2 is the layer identifier, and since the map sheet identifier and the layer identifier of both are the same, both belong to one data.

In step 202 of this embodiment, the processing device stores the data content in the update data in the database and generates corresponding download information. Then, the generated download information and the metadata in the update data are used for updating the data attribute and the data version of the update data in the database.

The update data specifically includes data content and metadata. The data content may be data in NDS format, such as NDS. And the metadata can adopt NDS metadata, and object codes (used for recording the issuing times), picture frame numbers, check codes, data formats, data sizes and data codes of the data can be stored in the metadata.

Further, the metadata of the update data includes an architectural identification of the update data, and the data attributes of the data in the database include an architectural identification of the data.

That is to say, correspondingly, the updating the data attribute of the update data in the database according to the metadata and the download information in step 202 specifically includes: determining data to be updated corresponding to the updated data according to the architecture identifier of the updated data and the architecture identifier of each data attribute in the database; and updating the download information in the data attribute of the data to be updated by using the download information of the update data.

The database stores and updates the update data by using the data architecture. Specifically, the data attributes of the database include architecture identifiers, that is, map sheet identifiers and map layer identifiers. As mentioned above, each data in the database is stored in association with the schema identification in the data attribute. When the database is updated, the following modes can be adopted:

firstly, according to the architecture identification in the metadata of the update data, determining the data to be updated in the database corresponding to the update data. That is, in the database, since the data are stored according to the architecture identifier, after receiving the update data, the object type, such as the terrain, of the update may be determined based on the layer identifier in the metadata; and then, determining the geographic area updated this time, such as the first geographic area, based on the map sheet identifier in the metadata. That is, the data content of this update is an update to the terrain in the first geographic area.

At this time, the data to be updated in the database, which is the same as the layer identifier and the map identifier, may be determined according to the obtained layer identifier and map identifier, that is, the data to be updated corresponding to the data attribute of the topographic data in the first geographic area that needs to be updated in the database may be found based on the identifier.

After the database determines the data to be updated, an update process is also required.

The update process includes storage of data content, update of data attributes of data to be updated, and update of versions of data to be updated.

When the data content of the updated data is stored in the database, the database also generates download information corresponding to the data content, and the download information and the metadata of the data form the data attribute of the data to be updated in the database. Wherein the download information can be used to determine the storage location of the data content in the database. That is to say, the download information needs to be updated or stored in the data attribute of the data to be updated, so as to ensure that the storage position of the data content can be conveniently found, and the client-side download is facilitated.

In addition, in order to ensure the subsequent fast query and output of the current update data, the version of the data to be updated needs to be updated. Wherein the version number of the database is related to the cumulative number of updates of the database. In other words, after updating the data attribute of the update data in the database, the version number of the database is updated; wherein the version number of the database is related to the cumulative number of updates of the database; and updating the version number of the data version according to the version number of the database.

Fig. 5a and 5b are schematic diagrams of a data updating flow in a data processing method of a high-precision map according to an embodiment of the present disclosure, as shown in fig. 5a, before updating, the number of times of updating a database is 0, a version of the high-precision map is V0, and a version of an image frame under each layer is also V0.

When the database is updated for the 1 st time, the minimum update unit may be data corresponding to one Layer identifier-map identifier, such as Layer1-Partition1 and Layer1-Partition2 shown in fig. 5 a. Therefore, after the new data content of the data corresponding to the two layer identifiers and the map width identifier is stored and the data attribute is updated, the original version number of the data content needs to be updated, that is, the version number is changed to V1.

Similarly, as shown in FIG. 5b, when the database is updated for the 2 nd time, the data to be updated are Layer1-Partition2 and Layer1-Partition 1. At this time, after the new data content of the data corresponding to the two layer identifiers — the map identifier is stored and the data attribute is updated, the original version number of the data needs to be updated, that is, the data is changed to V2.

In the embodiment provided by the present disclosure, steps 203 to 205 are processing manners of the data processing apparatus after receiving the update request initiated by the client.

Specifically, different from the foregoing embodiment, the process that the data processing apparatus in this embodiment determines the target data matching the target version based on the data version corresponding to each data stored in the database may have a plurality of implementation manners in this embodiment:

one is to use the data completely consistent with the target version as the target data, for example, as shown in fig. 5b, if the version is V2, the client requests the target version to be V2, and at this time, the data corresponding to Layer1-Partition 2V 2 and Layer2-Partition 1V 2 are sent to the client as the target data.

The second is to use data higher than or equal to the target version as the target data, for example, as shown in fig. 5b, if the version is V2, the client requests that the target version is V2, and at this time, data corresponding to each layer identifier-map width identifier in Catalog V2 is used as the target data.

Of course, the two processing manners may exist simultaneously, and in implementation, the distinguishing processing may be performed based on other identifiers in the update request, for example, when the update manner identifier in the update request indicates a local update, a first processing manner may be used, and when the update manner identifier in the update request indicates a global update, a second processing manner may be used.

Finally, after the confirmation of the target data is completed, the downloading information of the target data can be sent to the client side, so that the client side can download the target data based on the downloading information.

In order to further provide diversified services for the client, the data processing device can also provide query services for the client on the basis of the above embodiments while ensuring the security of data transmission by the data processing device.

Fig. 6 is a schematic flowchart of another data processing method for a high-precision map according to an embodiment of the present disclosure, and as shown in fig. 6, the data processing method includes:

301, receiving update data of a high-precision map uploaded by a request end; the update data comprises data content and metadata;

step 302, storing the data content in a database and generating corresponding downloading information, and updating the data attribute and the data version of the updated data in the database according to the metadata and the downloading information;

step 303, receiving a version query request initiated by a client;

and step 304, sending the version number of the database to a client according to the version query request.

Step 305, receiving an update request of the high-precision map initiated by a client, wherein the update request comprises a target version of the high-precision map;

step 306, determining target data matched with the target version according to the data version of each data in the database;

307, sending the downloading information in the data attribute of the target data to a client, so that the client can download the target data according to the downloading information and update the high-precision map; and the downloading information is generated when the target data is stored and is stored in the corresponding data attribute in an associated manner.

Similarly to the foregoing embodiment, the execution subject of the processing method provided by the present example is the foregoing high-precision map data processing apparatus, which can interact with the parties via a network.

steps

Unlike the foregoing embodiment, in the present embodiment, the data processing apparatus further receives a query request initiated by the client. The data processing device can send the version number of the database to the client according to the query request, wherein the version number of the database is determined according to the current updating times of the database.

And updating the current updating times of the database after the database is updated, namely updating the data attribute and the data version of the data to be updated in the database according to the metadata of the updating data, updating the accumulated updating times of the database by the data processing device, and updating the version number of the database according to the accumulated updating times of the database.

In addition, the query request includes client identity information. Based on the query request, the data processing device can authenticate the client according to the client identity information in the query request, and after the authentication is passed, the data processing device sends the current version of the high-precision map of the database to the client, so that the downloading safety of the client is ensured. The authentication process therein may be based on the prior art, which is not limited by this disclosure.

On the basis of the above embodiment, the present embodiment provides the query service to the client, so that the client can determine the required database version by using the query service, and the client can conveniently select the required target version based on the queried result for updating.

According to the data processing method of the high-precision map, the update data of the high-precision map uploaded by a request terminal is received, the data content of the update data is stored, the database is updated according to the metadata of the update data, and the update request of the high-precision map initiated by a client terminal is received, wherein the update request comprises the target version of the high-precision map; determining target data matched with the target version according to the data version corresponding to each data in the database; and sending the downloading information of the target data to a client so that the client can download the target data in the database according to the downloading information and execute updating. By adopting the mode, the automatic processing of receiving and sending the high-precision map data can be effectively realized, the data volume is relatively small during processing, and the processing efficiency is improved.
