Technical Field

The embodiment of the disclosure relates to the technical field of computers, in particular to the technical field of electronic maps.

Background

The main road usually refers to a road bearing the main pressure of urban traffic, and the main road usually only can drive motor vehicles. The auxiliary road generally refers to an auxiliary road of the main road, and is often adjacent to two sides or one side of the main road, and is a one-way or two-way driving road parallel to the main road. The auxiliary road is generally narrower than the main road, and motor vehicles, non-motor vehicles and pedestrians can travel in a mixed manner.

In general, the main road and the secondary road are closer to each other, so that when the specific positions of the addresses are located in the main road and the secondary road through the latitude and longitude information, even if the latitude and longitude information has a small deviation, the address of the secondary road is located in the main road. As an example, in a scene such as logistics, if there is a latitude and longitude information deviation in a receiving address of a user, it is highly likely that the receiving address that should be located on a side road is located on a main road, which tends to reduce the delivery efficiency of a courier.

Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, a schematic diagram of a first embodiment of a method for generating information according to the present application is shown. The method for generating information may comprise the steps of:

step 101, obtaining initial longitude and latitude information of a target position.

In this embodiment, the executing body of the method for generating information may be the apparatus for generating information, and the method for generating information may be an electronic entity (for example, a server), or may also be an application program integrated by software. When the device for generating the information is used, the initial longitude and latitude information of the target position can be obtained, and the obtained initial longitude and latitude information is corrected to obtain the final position information of the target position. The apparatus for generating information may determine final location information of the target location by using the method for generating information of the present embodiment.

In this embodiment, the execution subject (e.g., the server) may acquire the initial longitude and latitude information of the target location from another electronic device through a wired connection manner or a wireless connection manner. Here, the initial latitude and longitude information may include coordinate points consisting of the latitude and longitude of the target position. The target location may include, but is not limited to, a location indicated by a physical distribution shipping address. As an example, when a user inputs a target location indicated by a logistics receiving address and the like through a mobile phone positioning and the like, initial longitude and latitude information of the target location can be directly uploaded to the execution main body, and the execution main body can directly acquire the initial longitude and latitude information of the target location; or, after different users input target positions such as logistics receiving addresses through mobile phone positioning and the like, the target positions can be sent to the same system and the same electronic device, and the execution main body can obtain initial longitude and latitude information of the target positions.

Typically, the target location may be a delivery address for the stream. It is understood that in a complex scenario where there are major roads and minor roads, the destination of the logistics is usually not on the major road used only for driving the vehicle. As an example, in the logistics listing system, if the initial longitude and latitude information of the target position is identified to the main road, the logistics listing system may plan to the main road when performing the route planning, so that the distributor may go wrong if performing the distribution according to the route planning. Therefore, if the execution main body determines that the target position is located in the main road, it can be determined that the initial longitude and latitude information of the target position has an error, and at this time, the longitude and latitude information of the target position needs to be corrected, so as to obtain accurate position information of the target position. Of course, the method for generating information disclosed in the present application is not only applicable to a logistics scenario, but also applicable to other scenarios in which a main road does not exist theoretically at a position point indicated by initial position information of a target position, for example, a user taxi taking scenario.

And 102, determining initial position information corresponding to the initial longitude and latitude information.

In this embodiment, based on the initial longitude and latitude information acquired in step 101, the execution subject may determine the initial position information corresponding to the acquired initial longitude and latitude information by various means. As an example, the execution main body locally stores a corresponding relationship between longitude and latitude information and position information, and at this time, the execution main body may directly determine the initial position information corresponding to the initial longitude and latitude information from the local. Or, the execution main body may further send the acquired initial longitude and latitude information to the map platform, so that the map platform may acquire initial position information corresponding to the initial longitude and latitude information, and the execution main body may acquire the initial position information from the map platform. The initial location information may indicate a specific geographical location of the target location in the actual area. The initial position information may include a road section identifier of a road section to which the initial longitude and latitude information belongs, and the road section identifier is determined as an initial road section identifier of the target position. It is understood that the initial location information may include a road name, a road grade, and the like of a road segment to which the initial longitude and latitude information belongs, in addition to the initial road segment identifier. For a piece of position information, a unique position point can be determined in the actual road by using the position information.

It will be appreciated that for any road, the road may be divided into successive links, each of which may correspond to a latitude and longitude coordinate range. Further, in order to distinguish the respective links, different identification IDs may be set for different links. Therefore, the road section to which the longitude and latitude coordinates belong and the identification of the road section can be determined according to the longitude and latitude coordinates. However, for a certain longitude and latitude coordinate, if the longitude and latitude coordinate is located on a main road or a side road close to the main road, it is often difficult to accurately determine whether the longitude and latitude coordinate belongs to the main road or the side road. Therefore, the execution main body may determine the initial position information after determining the initial position information, so as to determine whether the initial road segment identifier is the road segment identifier of the main road segment or the road segment identifier of the auxiliary road segment.

Optionally, the corresponding relationship between the road segment identifier ID and the longitude and latitude information may be stored in a server of the map platform, so that the execution subject may perform information interaction with the map platform through an Application Programming Interface (API) of the map platform to obtain the road segment identifier corresponding to the longitude and latitude information, but the map platform often cannot accurately determine whether the initial road segment identifier is the road segment identifier of the main road segment or the road segment identifier of the auxiliary road segment. The execution subject may determine the initial position information after acquiring the initial position information from the map platform, so as to determine whether the initial road segment identifier is a road segment identifier of the main road segment or a road segment identifier of the auxiliary road segment.

And 103, in response to determining that the initial road section identifier is the main road section identifier of the main road, acquiring at least one auxiliary road section identifier corresponding to the initial road section identifier determined as the main road section identifier from a preset database.

In this embodiment, based on the initial segment identifier obtained in step 102, the execution principal may determine whether the initial segment identifier is a main segment identifier of the main road. If the initial road section identifier is a main road section identifier, the execution subject may consider that the acquired initial longitude and latitude information has an error, and the acquired initial road section identifier also has a deviation, and at this time, the initial road section identifier needs to be corrected. Specifically, the execution subject may obtain at least one auxiliary road segment identifier corresponding to the initial road segment identifier from a preset database.

It should be noted that the database may be pre-established, and the database may include a plurality of main segment identifiers, and each main segment identifier may be correspondingly provided with at least one auxiliary segment identifier. That is, each main road segment identifier has a corresponding relationship with at least one sub road segment identifier. For any main road section identifier in the database, the sub road section identifier corresponding to the main road section identifier needs to meet a preset condition. It is understood that the preset condition may be set by a person skilled in the art according to actual requirements, for example, the preset condition may be that the projection of the main road segment indicated by the main road segment identifier to the side road and the side road segment indicated by the side road segment identifier corresponding to the main road segment identifier at least partially coincide. Optionally, the main road segment identifier and the sub road segment identifier in the database may be the main road segment identifier and the sub road segment identifier acquired from the map platform, and then the corresponding relationship between the main road segment identifier and the sub road segment identifier may be established according to the position relationship between the main road segment indicated by the main road segment identifier and the sub road segment indicated by the sub road segment identifier in the map platform.

In some optional implementations of this embodiment, the database may be determined by: acquiring a plurality of main road section identifications and a plurality of auxiliary road section identifications; determining an auxiliary road section, of which the distance from the main road section indicated by the main road section identifier is smaller than a preset threshold, aiming at the main road section identifier in the main road section identifiers; and correspondingly setting the determined auxiliary road section identification of the auxiliary road section and the main road section identification to generate a database. According to the scheme provided by the implementation mode, under the condition that the initial longitude and latitude information has deviation, the road segment identifier used for correcting the initial position information can be comprehensively and accurately obtained, and the accuracy of the obtained final position information is improved.

In some optional implementation manners of this embodiment, if the initial road segment identifier is not a main road segment identifier, it may be considered that the execution subject obtains accurate initial longitude and latitude information, and at this time, the initial position information of the target position may be directly determined as the final position information of the target position.

And 104, correcting the initial position information based on the acquired at least one auxiliary road section identifier to obtain final position information of the target position.

In this embodiment, based on the at least one auxiliary link identifier obtained in step 103, the executing entity may process the obtained auxiliary link identifier by various means, so as to correct the initial position information of the target position by using the processing result, and obtain the final position information of the target position. As an example, the execution subject may select one auxiliary road segment identifier from the acquired at least one auxiliary road segment identifier, and use the longitude and latitude of a location point closest to the location point indicated by the initial longitude and latitude information in the auxiliary road segment indicated by the selected auxiliary road segment identifier as the longitude and latitude of the target location, and the map platform may determine the location information of the target location according to the longitude and latitude to replace the initial location information, where the location information is the final location information of the target location.

With continuing reference to fig. 2, fig. 2 is a schematic diagram of an application scenario of the method for generating information according to the present embodiment. In the application scenario of fig. 2, the background server may obtain initial longitude and latitude information of the target location; then, the background server may determine initial position information corresponding to the initial longitude and latitude information, as shown in fig. 2, a road segment to which the position point a indicated by the initial longitude and latitude information belongs is a road segment linkId1 closest to the position point a, the road segment is a road segment of the main road 201, and an identifier linkId1 of the road segment is an initial road segment identifier; then, in response to determining that the initial road segment identifier linkId1 is the main road segment identifier of the main road 201, the backend server acquires a secondary road segment identifier linkId2 and linkId3 corresponding to the initial road segment identifier linkId1 from a preset database, as shown in fig. 2, wherein the secondary road segment identifiers linkId2 and linkId3 belong to the secondary road 202; finally, based on the acquired link id2 and link id3, the initial position information is corrected, for example, by making a perpendicular line to the link 202, to obtain the final position information of the target position, and as shown in fig. 2, the position point indicated by the corrected initial position information is the position point a 'on the link indicated by the link id2, and the position information corresponding to the position point a' is the final position information of the target position.

The method for generating information according to the embodiment of the application may obtain initial longitude and latitude information of a target position, determine initial position information corresponding to the initial longitude and latitude information, obtain at least one auxiliary road segment identifier corresponding to the initial road segment identifier determined as the main road segment identifier from a preset database in response to determining that the initial road segment identifier is the main road segment identifier, and finally correct the initial position information based on the obtained at least one auxiliary road segment identifier to obtain final position information of the target position. According to the scheme disclosed by the embodiment, the position information of the target position can be fully automatically corrected under the condition that the target position deviates to the main road, manual intervention is not needed, and the accuracy of obtaining the final position information of the target position is improved.

Continuing next to refer to fig. 3, fig. 3 is a schematic diagram of a second embodiment of a method for generating information according to the present application. The method for generating information may comprise the steps of:

step 301, obtaining initial longitude and latitude information of a target position.

Step 302, determining initial position information corresponding to the initial longitude and latitude information.

Step 303, in response to determining that the initial road segment identifier is the main road segment identifier of the main road, obtaining at least one auxiliary road segment identifier corresponding to the initial road segment identifier determined as the main road segment identifier from a preset database.

In this embodiment, the contents disclosed in steps 301 to 303 are the same as or similar to the contents disclosed in steps 101 to 103 in the above embodiment, and are not described again here.

And step 304, determining a target positioning point from the secondary road segment indicated by the acquired at least one secondary road segment identifier.

In this embodiment, based on the at least one auxiliary road segment identifier obtained in step 303, the executing entity may determine the target positioning point from the obtained auxiliary road segment identifiers by various means. The target positioning point may be a position point with the minimum distance from the position point indicated by the initial longitude and latitude information in the auxiliary road section indicated by each auxiliary road section identifier. As an example, the execution subject may calculate a distance between a position point in the sub link indicated by each sub link identification and a position point indicated by the initial latitude and longitude information, and determine a position point, in the sub link indicated by each sub link identification, at which the distance is the smallest, as the target anchor point. Or, the execution main body makes a perpendicular line from the position point indicated by the initial longitude and latitude information to the road sub-segment indicated by each road sub-segment identifier, and the vertical line is the target positioning point.

And 305, determining the longitude and latitude information corresponding to the target positioning point as the target longitude and latitude information.

In this embodiment, based on the target positioning point determined in step 304, the executing body may obtain longitude and latitude coordinates of the target positioning point. And determining the acquired longitude and latitude coordinates as the target longitude and latitude information.

And step 306, determining theoretical position information of the target position based on the target longitude and latitude information.

In this embodiment, based on the target longitude and latitude information determined in step 305, the execution main body may process the location information corresponding to the target longitude and latitude information in various ways, so as to obtain the theoretical location information of the target location. As an example, the execution subject may send the target longitude and latitude information to a map platform, and the map platform may determine the location information corresponding to the target longitude and latitude information, and then process the location information corresponding to the target longitude and latitude information in various ways, so as to obtain theoretical location information of the target location. As an example, the map platform may directly determine the location information corresponding to the target longitude and latitude information as theoretical location information of the target location. It can be understood that the execution main body may also determine, in the correspondence between the latitude and longitude information and the location information stored locally in advance, that the location information corresponding to the target latitude and longitude information is theoretical location information. The theoretical position information of the target position may indicate a specific position of the target position in the map. It is understood that the theoretical location information may include an identification of the secondary road segment, a name of a road to which the secondary road segment belongs, and the like.

In some optional implementation manners of this embodiment, the correcting the initial position information based on the obtained at least one auxiliary road segment identifier to obtain the final position information of the target position may specifically be further implemented by: and sending the target longitude and latitude information to a map platform so that the map platform determines a target auxiliary road section identification corresponding to the target longitude and latitude information, updates the target longitude and latitude information based on the target auxiliary road section identification, and determines theoretical position information of a target position based on the updated target longitude and latitude information. In this implementation manner, after receiving the target longitude and latitude information, the map platform may determine an auxiliary road segment identifier corresponding to the target longitude and latitude information, where the auxiliary road segment identifier is the target auxiliary road segment identifier. It can be understood that there may be a deviation between the location point indicated by the target longitude and latitude information and the sub road segment indicated by the target sub road segment identifier (for example, if the distance between the location point indicated by the target longitude and latitude information and the sub road segment indicated by the target sub road segment identifier is greater than a preset distance, it may be determined that there is a deviation between the location point indicated by the target longitude and latitude information and the sub road segment indicated by the target sub road segment identifier), and at this time, the determined target sub road segment may be processed in various ways, so as to update the target longitude and latitude information. As an example, a perpendicular line may be drawn from the position point indicated by the target longitude and latitude information to the road sub-segment indicated by the target road sub-segment identifier, and a position point corresponding to a foot of the perpendicular line on the road sub-segment indicated by the target road sub-segment identifier is determined as the position point indicated by the updated target longitude and latitude information, so that the updated target longitude and latitude information may be obtained. And finally, the position information corresponding to the updated target longitude and latitude information can be directly determined as the theoretical position information of the target position. The scheme disclosed by the implementation mode can further correct the position information of the target position in the map platform by utilizing the acquired target auxiliary road section identification, so that the accuracy of the obtained final position information of the target position can be further improved.

Step 307, the theoretical position information is determined as the final position information of the target position.

In this embodiment, based on the theoretical position information obtained in step 306, the executing entity may obtain the theoretical position information from the map platform and determine the theoretical position information as the final position information of the target position.

As can be seen from fig. 3, compared with the embodiment corresponding to fig. 1, after at least one sub road segment identifier is obtained from the database, the method for generating information in this embodiment may determine, in the sub road segment indicated by each sub road segment identifier, a target location point having the smallest distance from a location point indicated by the initial longitude and latitude information, and re-determine location information of the target location by using the target longitude and latitude information, where the re-determined location information is the corrected initial location information and is also the final location information of the target location, thereby further improving the accuracy of the obtained final location information of the target location.
