Example 1

As shown in FIG. 1 , an embodiment of the present disclosure provides a method for updating map data, and the method includes the following steps.

Step S101: Obtain update information of first map data and a map sheet corresponding to the update information among the first map data.

In the embodiments of the present disclosure, the method for updating map data relates to data processing technology, particularly to map data, and can be widely applied to map data update scenarios. The corresponding method may be executed by the map data updating device according to an embodiment of the present disclosure. The map data updating device may be disposed in any electronic device to execute the map data updating method according to an embodiment of the present disclosure, and the corresponding electronic device may be a server or a terminal, which is not specifically limited herein. do.

The first map data may be data before updating the map, and the corresponding map may be formed by being spliced into a plurality of map sheets, and data formed by being correspondingly spliced will be referred to as first map data. can

The first map data may be map data of the world, map data of any country, map data of a certain administrative area, or map data of other areas, which are not specifically limited herein. decide not to

The update information may indicate an update change in the real world, and the update information may include at least one work data, among which the work data may refer to driving information in progress of a map data update process. One work data represents one update change in the real world. For example, one work data may include related information that an electronic eye is newly added to region A. Correspondingly, based on the working material, the map data updating device may be driven to update the map data.

There are various ways to obtain the update information of the first map data. For example, the update information of the first map data may be generated by acquiring work data uploaded by a user, and the work material may be downloaded from the network. Update information of the first map data may be generated, and work data stored in advance may be acquired to generate update information of the first map data, or work data transmitted by other electronic devices may be received, Update information of the first map data may be generated.

The work data of the update information may include a map location to be updated in space, and may include, for example, related information that an electronic eye is newly added to a certain location in area A, and correspondingly, the work data Obtain a map sheet that intersects with the working data of the update information and the map sheet among the map sheets corresponding to the first map data according to the spatial relationship between the first map data and the first map data. Among the map data, a map sheet corresponding to the update information is obtained.

Among them, the number of map sheets corresponding to the update information is determined according to the update range in the space among the work materials of the update information, and the number of map sheets may include one, It may include a plurality, and will not be specifically limited here. For example, if the update range in space among the work materials of the update information is related to the data of only one map sheet, the number of map sheets corresponding to the update information is one, and if the update information If the update range in space among the work materials of is related to data of a plurality of map sheets, the number of map sheets corresponding to the update information is plural.

In an actual application, prior to performing a map data update operation, it is possible to collect working data of the first map data to prepare update information, and correspondingly, a map sheet (map sheet) corresponding to the update information among the first map data sheet), and create a work task package based on this information.

Step S102: Based on the spatial update range of the update information, target data of the map sheet is cut to obtain first target map sheet data, and the first target map Map sheet data includes data falling within the spatial update range among the target data.

In this step, the spatial update range refers to the spatial operating range on the map of the working data of the update information, and the spatial operating range refers to the actual editing range when updating the map data, and the corresponding spatial update The range may be greater than or equal to the spatial range of a map sheet corresponding to the update information. That is, when updating map data, it may not be related to all data within the spatial range of the map sheet corresponding to the update information, and only actual editing within the map sheet corresponding to the update information. It can only relate to data within a range.

For example, the data within the spatial range of a map sheet corresponding to the update information may include map data of region A and region B, and only map data of region A is included in the working data of the update information. If it is indicated to be updated, the spatial update range corresponding to the update information is region A.

Accordingly, based on the spatial update range of the update information, target data of the map sheet may be cut to obtain first target map sheet data. Among them, the target data may mean all data within a spatial range of the map sheet.

Based on the spatial update range of the update information, there are various methods of cutting the target data of the map sheet. For example, the map sheet is cut according to the spatial update range of the update information. Cutting may be performed, for example, a partial map sheet including region A among the map sheets may be cut, and data within a spatial range of the cut partial map sheet may be a first target. This is map sheet data.

For example, according to the spatial update range of the update information, some data of the target data of the map sheet may be deleted. For example, data within the spatial update range of the map sheet may be deleted. It is reserved, and other data in the map sheet can be deleted, and the finally obtained first target map sheet data includes data falling within the spatial update range among the target data.

Depending on the characteristics of the work data, target data may be cut. For example, work data such as electronic eye data related to update content of point characteristics may be cut according to the point radiation space. Working data, such as road data regarding update contents of chain characteristics, may be cut according to the road chain space.

As shown in FIG. 2, FIG. 2 is an exemplary view of one map sheet, and a line 201 in the map sheet 200 represents data in the map sheet. , The work data corresponding to the map sheet is related to the electronic eye data 202, and cuts the target data with a radius of one predetermined distance, for example, 500 m, centered on the update position of the electronic eye. Processing may be performed to obtain cut map sheet data, and as shown in FIG. 3 , the data 301 in the form of a tree branch in the middle is reserved data, that is, the first target map sheet. (map sheet) data.

As shown in FIG. 4, FIG. 4 is another example of a map sheet, and a line 401 in the corresponding map sheet 400 is data in the map sheet. Indicates, the work data corresponding to the map sheet is related to the number of road lanes data 402, and based on the road bonded to the number of road lanes data, the left and right space of the road chain can be taken 100m, , It is possible to obtain cut map sheet data by tracking 1000 m (total 2000 m) along the road chain in front and back and cutting the target data. As shown in FIG. 5, the road Chain 501 is reserved data, that is, first target map sheet data.

In an actual application, before proceeding with a map data update operation, a first target map sheet is obtained by cutting target data of the map sheet based on the spatial update range of the update information. Data may be obtained, and specifically, a work task package is collected and generated based on the update information and the first target map sheet data, and the work task package is for performing a map data update work.

Step S103: Based on the first target map sheet data and the update information, the first map data is updated.

In this step, based on the work data of the update information, the first target map sheet data may be edited to obtain updated map sheet data, and thereafter, The first map data may be updated by fusing updated map sheet data with target data.

The first target map sheet data is edited based on the update location, update type, and update content displayed among the work materials corresponding to the update information, and the updated map sheet data can be obtained. Among them, the update type may include deletion, new addition, and modification, and the update content indicates what kind of change has occurred in the real world.

For example, the update position is position A in region A, the update type is new addition, the update content is electronic eye, that is, the work data indicates that an electronic eye is newly added to position A in region A, and the corresponding Specifically, the position corresponding to position A among the cut map sheets is edited to newly add data of one electronic eye among the cut map sheets, that is, the first target map sheet Among the (map sheet) data, map data displaying electronic eye information is newly added to obtain updated map sheet data.

For example, the update position is position B in region A, the update type is delete, the update content is electronic eye, that is, the work data indicates that an electronic eye is deleted at position B in region A; Correspondingly, the position corresponding to position B in the cut map sheet is edited to delete the data of one electronic eye in the cut map sheet, that is, the first target map sheet. Among the (map sheet) data, map data displaying electronic eye information is deleted to obtain updated map sheet data.

For example, the update position is position C in region A, the update type is modification, and the update content is to increase the number of lanes on the road, that is, the working data is to modify the number of lanes on the road at position C in region A. Correspondingly, the position corresponding to the position C in the cut map sheet is edited to correct the data of the number of road lanes in the cut map sheet, and the corresponding road The number of lanes is increased, that is, map data indicating the number of road lanes among first target map sheet data is modified to obtain updated map sheet data.

In addition, before proceeding with the editing process, an editable range corresponding to the first target map sheet data may be marked, and an editable range corresponding to the first target map sheet data may be marked. The editable range may not be marked, and will not be specifically limited to this here.

Correspondingly, if the number of work materials of the update information is greater than 1, based on all the work materials of the update information, edit processing is performed on the first target map sheet data to update the map sheet ( map sheet data may be obtained, and then, second map data may be obtained by fusing the updated map sheet data with the target data, and the second map data may include the first map data. It is map data after updating, and the corresponding second map data is other map sheets excluding the map sheet corresponding to the update information among the fused map sheet data and the first map data. ) contains the data of

In addition, based on the partial work data of the update information, the first target map sheet data may be edited to obtain updated map sheet data, and then updated map sheet data may be obtained. Map sheet data and target data may be fused, and based on other working materials, the fused map sheet data is edited and finally second map data is obtained.

In a real application, in the process of updating map data, for a work task package created by collecting, based on first target map sheet data and the update information in the work task package, the first map data You can proceed with the update.

In an embodiment of the present disclosure, obtaining update information of first map data and a map sheet corresponding to the update information among the first map data; Based on the spatial update range of the update information, target data of the map sheet is cut to obtain first target map sheet data, and first target map sheet data is obtained. sheet) data includes data falling within the spatial update range among the target data; and updates the first map data based on the first target map sheet data and the update information. By performing the cutting process on the target data of the map sheet, it is possible to reduce the amount of data of the map sheet set collected in the work task package, thereby reducing the amount of data in the work task package. and improve the work effect in the process of updating map data. For example, speed up the flow of work task packages, reduce occupancy of bandwidth, reduce loading time when performing map data update work, and improve data processing speed.

In addition, when the work task package is assembled, the quantity of work materials in the work task package can be placed in an economical range, thereby reducing the time cost and the sustained cost of artificially frequently switching tasks. can By reducing the amount of data corresponding to one work material so that the amount of data can be controlled, flow cost and loading cost can be greatly reduced.

Optionally, the update information includes M elements to be updated, M is a positive integer, and the step S103 is specifically:

obtaining second target map sheet data by performing editing processing on the first target map sheet data based on the M elements to be updated; and

obtaining second map data by performing a merging process on the second target map sheet data and the target data; includes

In an embodiment of the present disclosure, an element to be updated means an update content in work materials, for example, an electronic eye is updated or the number of lanes on a road is updated, and each work material includes one element to be updated. can

Second map data may be obtained by fusing (map sheet) data and target data, the second map data is map data after updating the first map data, and the second map data is the fused map. It includes map sheet data and other map sheet data other than a map sheet corresponding to the update information among the first map data.

In addition, based on an element to be partially updated among the M elements to be updated, the first target map sheet data may be edited to obtain updated map sheet data, After that, the updated map sheet data and the target data may be fused, and based on other work materials, the fused map sheet data may be edited and finally second map data Acquire

Among them, performing the merging process on the second target map sheet data and the target data means that, specifically, the target data and the second target map sheet data are newly added. The modified data may be added, and at the same time, the second target map sheet data may be replaced with modified data in the target data.

For example, target data is D1, cut map sheet data, that is, first target map sheet data, is D2, and edited map sheet data, that is, second target map sheet data is D2. ) data is set to be D3, the finally fused map sheet data may be D4 = (D3-D2) + D1.

In an embodiment of the present disclosure, the edit data for the element to be updated may be boundary data among first target map sheet data, and the corresponding boundary data excludes a map sheet corresponding to the update information. It can be linked to data in other map sheets, it can also be linked to deleted data in the map sheet, and if you modify boundary data, it can be linked to edited map sheet data and other map sheets. (map sheet) Data mismatch may occur. Therefore, after the cutting process, an editable range corresponding to the first target map sheet data may be marked, and data editing may be performed within the marked editable range.

The notation method may vary, for example, the range may be marked in a way of marking the boundary point, and when loading data, according to the boundary point identifier, the range corresponding to the related data is set as a range that cannot be edited. and set a range corresponding to other data among the first target map sheet data as an editable range, and the editable range is the first range. For example, a first range may be obtained by determining an editable range corresponding to the first target map sheet data in a polygonal display frame.

Correspondingly, the user may edit the first target map sheet data based on the work material within the corresponding first range. That is, if there is an element to be updated, that is, a first element to be updated whose update position is located in a first range among the M elements to be updated, the first target within a first range based on the first element to be updated.
