[0027] Exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings, which are provided to assist in a comprehensive understanding of the present disclosure by those of ordinary skill in the art, and they are considered merely to be 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 present disclosure. Also, in the following description, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0028] An embodiment of the present disclosure provides a map data collection method, applied to a server, which can be an electronic device such as a computer.

[0029] Please refer to Figure 1 , Figure 1 is a flowchart of a map data collection method provided by an embodiment of the present disclosure, and the method comprises the following steps:

[0030] In step S101, when it is detected that the collection vehicle starts to collect map data, the collection vehicle is connected to a default base station.

[0031] It should be noted that the collection vehicle can be a vehicle specially used for collecting map data, such as an autonomous vehicle, and the map data can be high-definition map data. The collection vehicle can collect road information, roadside information, etc. of the path it travels during driving, for example, it can take pictures based on a vehicle-mounted camera, and the map data can be image information taken by the collection vehicle. It can be understood that the map data can also include other forms of data content, which is not described in detail in the present disclosure.

[0032] Optionally, the collection vehicle can be connected to a server to upload vehicle driving information and state information in real time, and when the collection vehicle starts to collect map data, the server can know that the collection vehicle is currently in the state of collecting map data based on the driving information and state information uploaded by the collection vehicle. Therefore, the server can be connected to a default base station. For example, the server can send an instruction to the collection vehicle to connect to the default base station. The instruction can include location information and identity document (ID) of the default base station, etc. The collection vehicle can be connected to the default base station based on the instruction.

[0033] The default base station can be a pre-designated base station. In the embodiments of the present disclosure, any acquisition vehicle can first establish a communication connection with the default base station when starting to collect map data.

[0034] In step S102, the acquisition vehicle acquires first position information sent by the default base station, and the first position information is position information of the acquisition vehicle.

[0035] In the embodiments of the present disclosure, after the acquisition vehicle establishes a communication connection with the default base station, the acquisition vehicle can report its position information to the default base station, and the default base station sends the received position information of the acquisition vehicle to the server, so that the server can also know the current position of the acquisition vehicle.

[0036] In step S103, based on the first position information, a first base station closest to the acquisition vehicle is acquired from a preset base station coordinate network, and the acquisition vehicle is switched to establish a communication connection with the first base station.

[0037] It should be noted that the preset base station coordinate network is a grid of coordinates of a plurality of base stations, and the position information of each base station in the preset coordinate network can be obtained. Alternatively, the preset base station coordinate network can be marked with the coordinates of the default base station, that is, the default base station belongs to one of the plurality of base stations included in the preset base station coordinate network.

[0038] It can be understood that after the server acquires the first position information sent by the acquisition vehicle based on the default base station, the server can determine the current position of the acquisition vehicle based on the first position information, and then determine the first base station closest to the acquisition vehicle from the preset base station coordinate network. That is, the acquisition vehicle is currently in the communication coverage range of the first base station, and the acquisition vehicle is switched to establish a communication connection with the first base station. In this way, the acquisition vehicle can be switched to establish a communication connection with the first base station closest to it.

[0039] In step S104, the acquisition vehicle acquires map data collected based on the first base station.

[0040] It can be understood that after the acquisition vehicle establishes a communication connection with the first base station, the acquisition vehicle sends the map data collected by the acquisition vehicle to the server through the first base station. For example, the map data is high-precision map data, and the high-precision map data can be lane line information, roadside information, etc. collected by the acquisition vehicle during driving.

[0041] In the embodiments of the present disclosure, when the server obtains that the collection vehicle starts to collect map data, the server establishes a communication connection between the collection vehicle and a default base station. When the server obtains first position information sent by the collection vehicle based on the default base station, the server obtains, based on the first position information, a first base station closest to the collection vehicle from a preset base station coordinate network, and switches the collection vehicle to establish a communication connection with the first base station, and obtains map data collected by the collection vehicle based on the first base station. In this way, the collection vehicle sends its own position information by first establishing a communication connection with the default base station, and then the server can select the base station closest to the collection vehicle from the preset base station coordinate network, so as to switch the collection vehicle to establish a communication connection with the base station closest to it. Therefore, it is not necessary to determine the collection area before the collection vehicle collects data, which effectively improves the flexibility of the collection vehicle in collecting map data and improves the efficiency of map data collection.

[0042] Optionally, before the step S101, the method can further include:

[0043] obtaining position information of a plurality of base stations in a target area;

[0044] constructing the preset base station coordinate network covering the target area based on the position information of the plurality of base stations;

[0045] The preset base station coordinate network includes at least one coordinate grid, and one coordinate grid corresponds to at least one base station. The plurality of base stations include the default base station.

[0046] It should be noted that the target area can be a pre-set area, for example, the target area can be a certain province or several provinces, etc. For example, the server can obtain position information such as latitude and longitude information input by a user, and then determine the area covered by the latitude and longitude information as the target area. Further, the server can obtain the position information of all base stations in the target area based on a specific base station position query website, and construct the preset base station coordinate network covering the target area based on the position information of the base stations.

[0047] For example, the server receives a plurality of longitude and latitude information input by a user, determines a corresponding coverage range according to the plurality of longitude and latitude information, and determines the coverage range as a target area; further, the preset base station coordinate network covering the target area can be constructed based on a preset grid size, or the preset base station coordinate network can be constructed based on a grid size input by the user. For example, the grid size input by the user is received, so as to construct a preset base station coordinate network including at least one coordinate grid, and it is ensured that each coordinate grid corresponds to at least one base station; if the condition is not met, the size of the coordinate grid can be adjusted until it is ensured that each coordinate grid corresponds to at least one base station.

[0048] In the embodiments of the present disclosure, the preset base station coordinate network constructed can be marked with the coordinates (for example, longitude and latitude coordinates) of each base station, and then the server can find the nearest base station to the collection vehicle according to the coordinates of each base station marked in the preset base station coordinate network when the position information (for example, longitude and latitude) of the collection vehicle is obtained, so that the collection vehicle can establish a communication connection with any one of the base stations in the preset base station coordinate network, and is no longer limited to collecting map data only within the range of the designated base station, effectively expanding the collection range of the collection vehicle and improving the flexibility of the collection vehicle in collecting map data.

[0049] Optionally, after the step S104, the method can further include:

[0050] obtaining second position information of the collection vehicle sent based on the first base station;

[0051] obtaining a first distance between the collection vehicle and the first base station based on the second position information;

[0052] in a case where the first distance is greater than a preset distance, obtaining a second base station closest to the collection vehicle from a preset base station coordinate network based on the second position information, and switching the collection vehicle to establish a communication connection with the second base station;

[0053] obtaining map data collected by the collection vehicle based on the second base station.

[0054] It can be understood that the collection vehicle can be in a driving state during the map data collection process, and thus the position information of the collection vehicle is constantly changing. The collection vehicle can send its own position information (i.e., the second position information) to the server through the first base station in real time. During the driving process of the collection vehicle, the distance between the collection vehicle and the first base station is also changing, for example, the distance from the first base station can become farther and farther, and even the collection vehicle can be out of the communication coverage range of the first base station.

[0055] In the embodiment of the present disclosure, the server can calculate the first distance between the collection vehicle and the first base station based on the second position information sent by the collection vehicle. When the first distance is greater than the preset distance, the server selects the second base station closest to the collection vehicle from the preset base station coordinate network based on the position information of the collection vehicle, and switches the collection vehicle to establish a communication connection with the second base station. In this way, the communication connection between the collection vehicle and the base station can be switched in time based on the distance between the collection vehicle and the base station during the driving of the collection vehicle.

[0056] Optionally, the preset distance can be less than the communication coverage radius of the first base station, so as to avoid communication interruption of the collection vehicle when it exceeds the communication coverage of the base station, and ensure that the base station can be switched to establish a communication connection with another base station in time when it has not exceeded the communication coverage of the base station, so as to ensure that the collection vehicle can always be in a communication connection state with the base station, and ensure that the map data collected by the collection vehicle can be sent to the server, thereby ensuring the reliability of data transmission.

[0057] Optionally, in another implementation manner, the server can determine the driving direction of the collection vehicle based on the plurality of second position information sent by the collection vehicle, and then determine the second base station from the preset base station coordinate network based on the driving direction. For example, the second base station can be a base station located in front of the driving direction of the collection vehicle, or the driving direction of the collection vehicle is in the communication coverage range of the second base station. Further, after determining the second base station, the server can calculate the second distance between the collection vehicle and the second base station based on the position information of the collection vehicle. When the collection vehicle drives to a situation where the first distance between the collection vehicle and the first base station is greater than the second distance between the collection vehicle and the second base station, the server can send an instruction to the collection vehicle to establish a communication connection with the second base station, and then the collection vehicle switches to establish a communication connection with the second base station based on the instruction, so that the collection vehicle sends the map data collected by the collection vehicle to the server through the second base station. In this way, the communication connection switching between the collection vehicle and different base stations can be realized in time based on the position information reported by the collection vehicle during the driving of the collection vehicle, so as to ensure that the map data collected by the collection vehicle can be sent to the server through the base station, and ensure the reliability of map data transmission.

[0058] In the embodiment of the present disclosure, the preset base station coordinate network can ensure that the collection vehicle can switch the communication connection between different base stations during driving, so that it is not necessary to demarcate a collection area before collecting map data, and it is not necessary to specify the connectable base station, which makes the collection of map data by the collection vehicle more flexible, and improves the collection efficiency.

[0059] Optionally, after step S104, the method may further include:

[0060] If no map data and / or location information are received from the data collection vehicle via the first base station within a preset time period, the communication connection between the data collection vehicle and the first base station shall be disconnected.

[0061] In this embodiment of the disclosure, after the data collection vehicle establishes a communication connection with the first base station, the data collection vehicle sends the collected map data to the server through the first base station. It can be understood that once the data collection vehicle begins collecting map data, the collection process is continuous. Therefore, the data collection vehicle can send the collected map data to the server through the first base station in real time, or it can send it once at preset intervals.

[0062] If the server does not receive map data and / or location information sent by the data collection vehicle through the first base station within a preset time period, it indicates that the data collection vehicle has left the communication coverage area of ​​the first base station, or that the data collection vehicle has stopped collecting map data, or that the data collection vehicle has experienced a data collection failure. In this case, the server can send a command to the data collection vehicle to disconnect from the first base station, and the data collection vehicle can then disconnect from the first base station upon receiving the command. This avoids the data collection vehicle remaining in a communication connection with the first base station when it is not sending map data and / or location information, thereby effectively saving the power consumption of the data collection vehicle.

[0063] Optionally, in this embodiment of the application, before step S101, the method may further include:

[0064] Log in to the server using the target account;

[0065] Wherein, when the data collection vehicle establishes a communication connection with the target base station, the target account is bound to the target base station, and the target base station is any base station in the preset base station coordinate network.

[0066] It should be noted that the method provided in this embodiment is applied to a server. For example, the server may be a service platform for high-precision map processing, and the target account may be an account that logs into the service platform. Thus, the target account has the relevant permissions of the service platform, such as the permission to draw and modify high-precision maps.

[0067] In the embodiments of the present disclosure, a user can log in to the server based on a target account, so that the user can obtain relevant permissions of the server through the target account. For example, when the server obtains that the collection vehicle starts to collect map data, for example, the server knows that the collection vehicle is currently in a state of collecting map data based on the driving information and state information uploaded by the collection vehicle, the server controls the collection vehicle to establish a communication connection with a default base station, and binds the target account with the default base station, so that the target account can obtain the first position information uploaded by the collection vehicle through the default base station. When the collection vehicle switches to establish a communication connection with a first base station, the binding relationship between the target account and the default base station is released, and the target account is bound with the first base station, so that the target account can obtain the collected map data sent by the collection vehicle through the first base station, and the target account can perform relevant processing based on the received map data, such as implementing high-precision map drawing, modification, and the like. Similarly, when the collection vehicle switches to establish a communication connection with a second base station or other base station, the target account is bound with the second base station or the other base station.

[0068] In the embodiments of the present disclosure, when the collection vehicle establishes a communication connection with a target base station in the preset base station coordinate network, the target account is bound with the target base station, so that the target account can obtain the collected map data sent by the collection vehicle to the server through the target base station, thereby ensuring that the user can log in to the target account to process the map data.

[0069] It should be noted that when the target account is in a login state, the target account can only establish a binding relationship with one base station, so that the target account can only obtain the map data uploaded by the collection vehicle through the base station, avoiding data confusion caused by the target account being bound with multiple base stations and receiving map data uploaded by multiple collection vehicles, and ensuring data clarity in the map making process.

[0070] Optionally, after the communication connection between the collection vehicle and the first base station is disconnected, the method further comprises:

[0071] Releasing the binding relationship between the target account and the first base station.

[0072] It can be understood that the collection vehicle establishes a binding relationship with the first base station when the collection vehicle establishes a communication connection with the first base station. After the service end sends an instruction to the collection vehicle to disconnect the communication connection with the first base station, the service end can also synchronously release the binding relationship between the target account and the first base station, and then the first base station is equivalent to an idle state, and can establish a binding relationship with other accounts, and the target account is also in an idle state, so as to ensure that the target account can establish a binding relationship with other base stations when the collection vehicle establishes a communication connection with the other base stations, and ensure that the target account can obtain the map data sent by the collection vehicle through the other base stations, and protect the user from processing the map data through the target account.

[0073] For better understanding, the map data collection method provided by the present disclosure is explained and described below through a specific embodiment.

[0074] Please refer to Figure 2 , Figure 2 is an application scenario of the map data collection method provided by the present embodiment of the present disclosure. As shown in Figure 2 , the service end first initializes a preset base station coordinate network covering a target area, Figure 2 one circle represents one grid, and M represents a base station (such as M1, M2, …, M11) in the grid. Among them, vehicle 1 and vehicle 2 are initially located in the grids of M2 and M3 respectively, and the vehicle end will first connect to the default base station when starting to collect map data, so as to obtain its own position information through the default base station; the vehicle end sends the position information to the service end, and the service end traverses the preset base station coordinate network, finds that vehicle 1 is closest to M2 and vehicle 2 is closest to M3, and therefore establishes a communication connection between vehicle 1 and M2 and a communication connection between vehicle 2 and M3 respectively; when vehicle 1 slowly drives to M6 and the distance between vehicle 1 and M2 exceeds a preset distance (for example, 20 km), the service end finds that vehicle 1 is closest to M6, and then controls vehicle 2 to switch to establish a communication connection with M6. In addition, if vehicle 2 does not drive, and assuming that M3 does not receive the map data sent by the vehicle end within a preset time (for example, for 5 minutes), the communication connection between vehicle 2 and M3 is disconnected, at this time, M3 is in a closed state for the service end, that is, the base station is not bound with the account of the service end.

[0075] In the present embodiment, the service end can select the base station closest to the collection vehicle from the preset base station coordinate network based on the position information of the collection vehicle by initializing a preset base station coordinate network, so as to switch the collection vehicle to establish a communication connection with the base station closest to the collection vehicle, and thus it is not necessary to determine the collection area before the collection vehicle collects data, which effectively improves the flexibility of the collection vehicle in collecting map data and improves the efficiency of collecting map data.
