The main road is usually a road bearing the main pressure of urban traffic, and the main road can only drive motor vehicles. An auxiliary road is usually an auxiliary road of a main road, and is often a unidirectional or bidirectional driving road parallel to the main road, which is adjacent to both sides or one side of the main road. The auxiliary road is generally narrower than the main road, and motor vehicles, non-motor vehicles and pedestrians can be mixed.
In general, the distance between the main road and the auxiliary road is relatively short, so that when the specific positions of the addresses are located in the main road and the auxiliary road through the longitude and latitude information, even if the longitude and latitude information has small deviation, the situation that the addresses of the auxiliary road are located to the main road can occur. As an example, in the case of logistics, etc., if there is a deviation in latitude and longitude information of the receiving address of the user, it is highly likely that the receiving address that should be on the auxiliary road is located to the main road, which tends to reduce the delivery efficiency of the courier.

Detailed Description
Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. 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 application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. 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 include the steps of:
Step 101, obtaining initial longitude and latitude information of a target position.
In this embodiment, the execution subject of the method for generating information may be the apparatus for generating information, and the method for generating information may be an electronic entity (e.g., a server), or may be an application program integrated with software. When the device for generating the information is used, the initial longitude and latitude information of the target position can be acquired, and the acquired 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 position information of the target position using the method for generating information of the present embodiment.
In this embodiment, the executing body (e.g., a server) may acquire the initial latitude and longitude information of the target location from another electronic device through a wired connection manner or a wireless connection manner. Here, the initial longitude and latitude information may include a coordinate point composed of longitude and latitude of the target position. The target location may include, but is not limited to, a location indicated by a shipping address. As an example, when a user inputs a target location indicated by a logistics receiving address or the like through a mobile phone positioning or the like, the user may directly upload initial longitude and latitude information of the target location to the execution subject, and the execution subject may directly obtain the initial longitude and latitude information of the target location; or after inputting the target position such as the logistics receiving address by a mobile phone positioning mode and the like, different users can also send the target position to the same system and electronic equipment, and the execution main body can acquire the initial longitude and latitude information of the target position.
In general, the target location may be a delivery address of the stream. It will be appreciated that in complex scenarios where both main and auxiliary routes are present, the destination of the logistics distribution will not typically be on the main route for driving the motor vehicle only. As an example, in the logistics scheduling system, if the initial longitude and latitude information of the target position is identified to the main road, the logistics scheduling system is caused to plan to the main road when the route planning is performed, so that a dispatcher can walk wrong if the dispatcher performs distribution according to the route planning. Therefore, if the execution subject determines that the target position is located in the main road, it can be determined that an error exists in the initial longitude and latitude information of the target position, 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 by the application is not only applicable to logistics scenes, but also applicable to other scenes where the position point indicated by the initial position information of the target position theoretically does not have a main road, such as a driving scene of a user, and the scene to which the method for generating information disclosed by the application is applicable is not limited only.
Step 102, determining initial position information corresponding to the initial longitude and latitude information.
In this embodiment, based on the initial latitude and longitude information acquired in step 101, the execution subject may determine the initial position information corresponding to the acquired initial latitude and longitude information by using various means. As an example, the executing body may directly determine the initial position information corresponding to the initial latitude and longitude information from the local place when the executing body locally stores the correspondence between the latitude and longitude information and the position information. Or the executing body can also send the acquired initial longitude and latitude information to the map platform, so that the map platform can acquire initial position information corresponding to the initial longitude and latitude information, and the executing body can acquire the initial position information from the map platform. The initial position information may indicate a specific geographic position of the target position in the actual area. The initial position information may include a link identifier of a link to which the initial longitude and latitude information belongs, and the link identifier is determined as an initial link identifier of the target position. It is understood that the initial position information may include, in addition to the initial link identifier, a road name, a road level, etc. of the link to which the initial longitude and latitude information belongs. For one piece of position information, a unique position point can be determined in the actual road by using the position information.
It can be appreciated that for any road, the road may be divided into continuous links, where each link may correspond to a latitude and longitude coordinate range. Further, in order to distinguish the road segments, different identification IDs may be set for different road segments. 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 in a main road or an auxiliary road which is very 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 auxiliary road. Therefore, the executing 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 primary road segment or the road segment identifier of the secondary road segment.
Optionally, the correspondence between the road segment identifier ID and the latitude and longitude information may be stored in a server of the map platform, so the executing body may perform information interaction with the map platform through an API interface (Application Programming Interface, application program interface) of the map platform to obtain the road segment identifier corresponding to the latitude and longitude 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 body may determine the initial position information after acquiring the initial position information from the map platform, so as to determine whether the initial road section identifier is a road section identifier of the main road section or a road section identifier of the auxiliary road section.
And step 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 to be the main road section identifier from a preset database.
In this embodiment, based on the initial link identifier obtained in step 102, the executing body may determine whether the initial link identifier is a main link identifier of a main link. If the initial link identifier is the main link identifier, the execution body may consider that the acquired initial longitude and latitude information has an error, and the obtained initial link identifier also has a deviation, and at this time, correction processing needs to be performed on the initial link identifier. Specifically, the executing body may acquire at least one auxiliary road section identifier corresponding to the initial road section identifier in a preset database.
It should be noted that the database may be pre-established, and the database may include a plurality of primary road section identifiers, where each primary road section identifier may be correspondingly provided with at least one secondary road section identifier. That is, each primary road segment identifier has a correspondence with at least one secondary road segment identifier. Aiming at any main road section identifier in the database, the auxiliary road section identifier corresponding to the main road section identifier needs to meet preset conditions. It is understood that the above-mentioned preset condition may be set by those skilled in the art according to actual requirements, for example, the above-mentioned preset condition may be that the projection of the main road segment indicated by the main road segment identifier to the auxiliary road and the auxiliary road segment indicated by the auxiliary road segment identifier corresponding thereto at least partially overlap. Optionally, the main road section identifier and the auxiliary road section identifier in the database may be a main road section identifier and an auxiliary road section identifier obtained from the map platform, and then a corresponding relationship between the main road section identifier and the auxiliary road section identifier may be established according to a positional relationship between the main road section indicated by the main road section identifier and the auxiliary road section indicated by the auxiliary road section 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 identifiers and a plurality of auxiliary road section identifiers; determining an auxiliary road section with the distance between the auxiliary road section and the main road section indicated by the main road section identifier being smaller than a preset threshold value aiming at the main road section identifier in the plurality of main road section identifiers; and setting the auxiliary road section identifier of the determined auxiliary road section corresponding to the main road section identifier 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 auxiliary road segment identification which can be 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 implementations of this embodiment, if the initial link identifier is not the main link identifier, the executing body may be considered to obtain accurate initial latitude and longitude 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 segment identifier to obtain final position information of the target position.
In this embodiment, based on the at least one auxiliary road segment identifier obtained in step 103, the executing body may process the obtained auxiliary road segment identifier by using 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 executing body may select one auxiliary road segment identifier from the obtained at least one auxiliary road segment identifier, take the longitude and latitude of the position point closest to the position 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 position, and the map platform may determine the position information of the target position according to the longitude and latitude to replace the initial position information, where the position information is the final position information of the target position.
With continued 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 acquire initial longitude and latitude information of the target position; then, the background server may determine initial position information corresponding to the initial longitude and latitude information, as shown in fig. 2, a road section to which the location point a indicated by the initial longitude and latitude information belongs is a road section linkId1 closest to the location point a, the road section is a road section of the main road 201, and the identifier linkId of the road section is an initial road section 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 background server acquires auxiliary road segment identifiers linkId and linkId corresponding to the initial road segment identifier linkId1 from a preset database, as shown in fig. 2, wherein the auxiliary road segment identifiers linkId and linkId3 belong to the auxiliary road 202; finally, based on the obtained auxiliary road segment identifiers linkId and linkId, the initial position information is corrected, for example, by making a vertical line to the auxiliary road 202, so as to obtain final position information of the target position, and as shown in fig. 2, the position point indicated by the corrected initial position information is a position point a 'on the auxiliary road segment indicated by the auxiliary road segment identifier linkId, and the position information corresponding to the position point a' is final position information of the target position.
According to the method for generating information provided by the embodiment of the application, the initial longitude and latitude information of the target position can be acquired, the initial position information corresponding to the initial longitude and latitude information is determined, then the main road section identifier of which the initial road section identifier is the main road is determined, at least one auxiliary road section identifier corresponding to the initial road section identifier which is determined to be the main road section identifier is acquired from the preset database, and finally the initial position information can be corrected based on the acquired at least one auxiliary road section identifier, so that the final position information of the target position is obtained. According to the scheme disclosed by the embodiment, the position information of the target position can be automatically corrected under the condition that the target position deviates from the main road, manual intervention is not needed, and the accuracy of obtaining the final position information of the target position is improved.
With continued reference 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 include 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.
In step 303, in response to determining that the initial road segment identifier is a main road segment identifier of the main road, at least one auxiliary road segment identifier corresponding to the initial road segment identifier determined to be the main road segment identifier is obtained from a preset database.
In this embodiment, the disclosure of steps 301 to 303 is the same as or similar to that of steps 101 to 103 in the above embodiment, and will not be repeated here.
And step 304, determining a target locating point from the auxiliary road section indicated by the acquired at least one auxiliary road section identifier.
In this embodiment, based on the at least one auxiliary road segment identifier obtained in step 303, the executing body may determine the target positioning point from the obtained auxiliary road segment identifiers by using various means. The target positioning point may identify, for each auxiliary road section, a position point with a minimum distance from a position point indicated by the initial longitude and latitude information in the indicated auxiliary road section. As an example, the above-described execution subject may calculate a distance between a position point in the auxiliary road section indicated by each auxiliary road section identification and a position point indicated by the initial latitude and longitude information, and determine a position point in the auxiliary road section indicated by each auxiliary road section identification, at which the distance is minimum, as the target anchor point. Or the execution main body makes a vertical line from a position point indicated by the initial longitude and latitude information to an auxiliary road section indicated by each auxiliary road section identifier, and the foot of the vertical line is the target positioning point.
Step 305, determining longitude and latitude information corresponding to the target positioning point as target longitude and latitude information.
In this embodiment, based on the target positioning point determined in step 304, the executing body may acquire longitude and latitude coordinates of the target positioning point. And determining the acquired longitude and latitude coordinates as target longitude and latitude information.
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 latitude and longitude information determined in step 305, the execution subject may process the position information corresponding to the target latitude and longitude information in various manners, so as to obtain the theoretical position information of the target position. As an example, the executing body may send the target longitude and latitude information to a map platform, and the map platform may determine the position information corresponding to the target longitude and latitude information, and then process the position information corresponding to the target longitude and latitude information in various manners, so as to obtain the theoretical position information of the target position. As an example, the map platform may directly determine the position information corresponding to the target longitude and latitude information as theoretical position information of the target position. It can be understood that the executing body may further determine, in the correspondence between the longitude and latitude information and the position information stored in advance locally, that the position information corresponding to the target longitude and latitude information is theoretical position information. The theoretical location information of the target location may indicate a specific location of the target location in the map. It is understood that the theoretical location information may include an auxiliary link identifier, a name of a road to which the auxiliary link belongs, and the like.
In some optional implementations 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 further be 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 identifier corresponding to the target longitude and latitude information, updates the target longitude and latitude information based on the target auxiliary road section identifier, and determines theoretical position information of the 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 section identifier corresponding to the target longitude and latitude information, where the auxiliary road section identifier is the target auxiliary road section identifier. It will be appreciated that the location point indicated by the target longitude and latitude information may deviate from the auxiliary road segment indicated by the target auxiliary road segment identifier (for example, if the distance between the location point indicated by the target longitude and latitude information and the auxiliary road segment indicated by the target auxiliary road segment identifier is greater than a preset distance, it may be determined that the location point indicated by the target longitude and latitude information deviates from the auxiliary road segment indicated by the target auxiliary road segment identifier), and at this time, the determined target auxiliary road segment may be processed in various manners, so as to update the target longitude and latitude information. As an example, a perpendicular line may be drawn to the auxiliary road segment indicated by the target auxiliary road segment identifier by the position point indicated by the target longitude and latitude information, and the position point corresponding to the perpendicular line on the auxiliary road segment indicated by the target auxiliary road segment identifier is determined as the position point indicated by the updated target longitude and latitude information, so that updated target longitude and latitude information may be obtained. 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 manner can further correct the position information of the target position in the map platform by utilizing the obtained target auxiliary road section identifier, so that the accuracy of the final position information of the obtained target position can be further improved.
In step 307, the theoretical position information is determined as final position information of the target position.
In this embodiment, based on the theoretical position information obtained in step 306, the executing body may acquire the theoretical position information from the map platform, and determine the theoretical position information as 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 auxiliary road segment identifier is obtained from the database, the method for generating information in this embodiment may determine, in the auxiliary road segment indicated by each auxiliary road segment identifier, a target positioning point with the smallest distance from the position point indicated by the initial longitude and latitude information, and redetermine the position information of the target position by using the target longitude and latitude information, where the redetermined position information is the corrected initial position information and is also the final position information of the target position, so as to further improve the accuracy of the obtained final position information of the target position.
