Example Embodiment

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.
[0018] First of all, it should be noted that in the embodiment of this application, the entities involved mainly include: mobile collection devices (for example, driving recorders, mobile smart terminals, etc.) and their corresponding servers (in this embodiment, the server Can store map data, etc.). In the embodiments of the present application, the entities are independent of each other and cooperate with each other. The specific implementation manner is described in detail below.
[0019] Terminal side method embodiment
[0020] See figure 1 From the perspective of the terminal side, that is, the mobile collection device, this embodiment provides a method for collecting geographic information data. The method includes the following steps:
[0021] S101: Record driving data in real time.
[0022] In this embodiment, the mobile collection device includes, but is not limited to, a driving recorder and a mobile smart terminal. In specific implementation, the mobile collection device can be pre-installed in the vehicle, and the mobile collection device can record the driving data of the vehicle in real time, including real-time shooting of video data during the driving process of the vehicle, and real-time collection of its global positioning system according to the driving route of the vehicle ( GPS, Global Positioning System) data, real-time collection of voice data during driving.
[0023] S102: When a user's collection instruction is received and/or a preset automatic collection condition is met, corresponding driving data is extracted and sent to the server, so that the server can update the current map data according to the received driving data.
[0024] In this embodiment, the collection function can be triggered in the following two situations. The collection function can be to obtain driving data in a corresponding time period or a corresponding geographic range and send it to the server. Here, taking the mobile collection device using the driving record as an example, the two types are described as follows:
[0025] The first case: see figure 2 , Is a schematic diagram of the user actively triggering the collection function. In this embodiment, an operation option 21 (for example, a "collect" button) for receiving collection instructions can be provided in the interface 20 of the mobile collection device related application (APP). When the vehicle is driving, the user finds that the road conditions are different. Change, for example, a traffic light is added to a certain road, a road is added to a certain area, etc., the user can actively trigger the operation option 21, and the mobile collection device can receive the collection from the user through the operation option 21 Instructions, in this case, the driving data within a preset time period can be extracted and sent to the server. The preset time period can be set according to actual needs. In this embodiment, the preset time period may be, for example, driving data recorded 15 minutes before the trigger operation and 15 minutes after the trigger operation.
[0026] That is to say, in the case where the user actively triggers the collection function, the server can receive the driving data recorded within a preset time period (for example, 15 minutes before and after the trigger operation) provided by the mobile collection device according to the user's collection instruction.
[0027] The second case: When the preset automatic acquisition conditions are met, the system automatically triggers the acquisition function. In this case, there are two ways:
[0028] 1) In one method, after the mobile acquisition device records the driving data in real time, the GPS data in the driving data can also be sent to the server in real time.
[0029] When the server receives the GPS data sent by the mobile collection device in real time, it can compare the GPS track composed of the GPS data with the current map data in the server, that is, the GPS data is differentiated from the current map data. The missing part of the data (for example, a missing road) or the part with inconsistent shape (for example, the shape of a road is inconsistent) can be determined as the area where the map data has changed, and the corresponding geofence (Geo- Fencing) information (that is, a virtual geographic boundary is enclosed by a virtual fence), and then the geographic fencing information can be sent to each mobile collection device.
[0030] The mobile collection device can receive and store the geofence information sent by the server.
[0031] Based on this, when the mobile collection device determines whether the current vehicle is within the area corresponding to the geofence information based on the GPS data it collects and the received geofence information, if the current vehicle is currently within the area corresponding to the geofence information When the time, it can meet the preset automatic collection conditions. In this case, the driving data recorded in the area corresponding to the geofence information can be automatically extracted and sent to the server.
[0032] 2) In another way, information related to changes in geographic information can be obtained through the Internet, government agencies, etc., for example, a new expressway is opened in a certain area, a park is added in a certain area, etc. The above-mentioned geographic information change situation determines the change information of the map data, and generates corresponding geofence information, and can send the geofence information to the mobile collection device.
[0033] The mobile collection device can receive and store the geofence information sent by the server. Based on this, when the mobile collection device determines whether the current vehicle is within the area corresponding to the geofence information based on the GPS data it collects and the received geofence information, if the current vehicle is currently within the area corresponding to the geofence information When the time, it can meet the preset automatic collection conditions. In this case, the driving data recorded in the area corresponding to the geofence information can be automatically extracted and sent to the server.
[0034] That is to say, in the case that the system automatically triggers the collection function when the preset automatic collection conditions are met, the server receives the driving data recorded by the mobile collection device in the area corresponding to the geofence information.
[0035] In the case where the user actively triggers the collection function or the system automatically triggers the collection function when the preset automatic collection conditions are met, it can help the server to receive the above-mentioned changed geographic information data that needs to be updated from the mobile collection device in time. .
[0036] After the server receives the above-mentioned driving data sent by the mobile collection device, it can further determine whether the received driving data is qualified data. If it is qualified data, it can perform operations such as updating the current map data according to the driving data. If it is unqualified data, it can be discarded and continue to wait for receiving qualified data.
[0037] In practical applications, determining whether the driving data is qualified data, for example, may include: determining whether the GPS trajectory composed of GPS data is clear and continuous, if the GPS trajectory is clear and continuous, it is qualified data, so that The missing or inconsistent parts of the map are effectively updated; determine whether the video data is clear, if the video data is clear, it is qualified data, so that the scene in the video can be clearly identified. In addition, it can be determined whether the GPS data is repeated data, and if it is not repeated data, it is qualified data.
[0038] After determining that the received driving data is qualified data, the qualified driving data can be input to the relevant data entry platform, so that the data entry platform can update the existing map data in time according to the newly received geographic information data. At the same time, the qualified data can also be marked to identify that the task corresponding to the triggered collection function has ended. There is no need to collect geographic information data within the geographic range corresponding to the qualified data to avoid unnecessary Repeat the operation.
[0039] As an optional implementation, taking the mobile collection device using a smart phone as an example, the above geographic information data collection method is designed as an application, which is configured on the smart phone, and can register and change account information, record and display personal collection results , Sharing, collecting information and interacting, including contribution rankings, simple social functions, such as likes and following. In addition, it can also have payment functions, get rewards or purchase goods, etc.
[0040] According to the above solution in this embodiment, the following advantages can be obtained:
[0041] First, because a large number of operating vehicles can be configured, it is far superior to the existing manual collection methods in terms of range coverage and coverage frequency. For example, according to this embodiment, 300 driving recorders are installed in the city. , Usually one day can cover the entire city once; while the existing manual collection method usually configures about 3 vehicle groups, it can only achieve complete coverage twice a year, and each coverage period is about one month.
[0042] Secondly, based on the above-mentioned higher coverage and frequency, the probability and timeliness of discovering changes in geographic information has also been significantly improved. Third, compared with the existing manual collection method, not only the labor cost is reduced, but also the overall cost is significantly reduced.
[0043] Server side method embodiment
[0044] This embodiment corresponds to the above-mentioned method embodiment on the mobile collection device side, and is a method for processing collected data on the server side. See image 3 , Which is a schematic flow diagram of a geographic information data collection method provided by this embodiment from the perspective of a server, and the method may include the following steps:
[0045] S201: Receive driving data sent by a mobile collection device.
[0046] Wherein, the driving data may include video data, GPS data, and voice data during driving.
[0047] S202: After determining that the driving data is qualified data, update current map data according to the driving data.
[0048] Wherein, determining that the driving data is qualified data may include: determining that the GPS trajectory composed of GPS data is clear and continuous, and determining that the video data is clear, so that the scene situation in the video can be clearly identified.
[0049] In practical applications, in a case where the mobile collection device receives a user collection instruction, S201 may include receiving driving data within a preset time period provided by the mobile collection device according to the user collection instruction.
[0050] In addition, in one case, the server can also receive the GPS data sent by the mobile collection device in real time, compare the GPS data with the current map data to determine the area where the map data is sent and generate the corresponding geofence information, and then Send the geo-fence information to a mobile collection device; in another case, information related to changes in geographic information can be obtained through the Internet, government agencies, etc., for example, a new expressway is opened in a certain area, and a new one is added in a certain area For parks, etc., we can determine map data change information based on the above-mentioned geographic information changes on the server side, and generate corresponding geofence information, and can send the geofence information to mobile collection devices.
[0051] Based on this, S201 may include receiving the driving data of the mobile collection device in the area corresponding to the geofence information.
[0052] Since the method embodiment on the server side corresponds to the method embodiment on the mobile collection device side, the relevant specific implementation can refer to the introduction in the method embodiment on the mobile collection device side, which will not be repeated here.
[0053] The geographic information data collection method provided by the embodiments of the present application can be applied to mobile collection devices and their corresponding servers. The mobile collection device can record driving data in real time, and can receive collection instructions from users and/or meet preset requirements. Under the automatic collection conditions, the relevant driving data is extracted and sent to the server; correspondingly, the server can receive the driving data sent by the mobile collection device, and after determining that the driving data is qualified data, compare the driving data according to the driving data The current map data is updated. In this way, it can replace the existing method of manually collecting geographic information data to use mobile collection equipment installed in vehicles to collect geographic information data. Based on the characteristics of the large number of vehicles on the road and the diversification of driving areas, one On the one hand, it can solve the problem of incomplete coverage of the collection due to the limitation of the number of collectors, and at the same time increase the coverage frequency; on the other hand, it can shorten the data collection period, improve the efficiency of data collection, and improve the update of geographic information data. Timeliness to ensure the freshness of geographic information data; in addition, it can also save labor costs, thereby reducing the cost of the entire data collection work.
