Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a first process for acquiring path information according to an embodiment of the present disclosure, which includes the following steps:
s101: the terminal receives a path end point input by a user.
In real life, a user is unfamiliar in the way of going out, so that the user can use a map navigation application in a terminal to smoothly arrive at a destination. When a user uses the map navigation application, a route starting point and a route ending point can be input according to actual needs, wherein a terminal usually defaults the current position of the terminal as the route starting point, and the terminal can be a mobile phone or other terminal equipment.
For example, a distributor at a certain logistics site needs to distribute a piece of goods to a resident living in a cell 321 of beijing city, 39, but since the distributor does not know the specific location of the cell 321 of beijing city, 39, the distributor opens a map navigation application in a mobile phone (i.e., a terminal), inputs "the cell 321 of beijing city, 39" in a cell in the cell, receives the path end input by the distributor, defaults the current location of the mobile phone as the path start point (i.e., the logistics site), and makes a corresponding response according to the input of the distributor.
S102: and when the terminal does not find the path information from the current position to the path end point in the server, taking the current position as a path starting point and collecting the position information of the terminal.
In the embodiment of the application, after the terminal receives the route end point input by the user and determines that the current position of the terminal is the route start point, the terminal can search the route information from the current position to the route end point according to the electronic map. The electronic map may be stored in a map navigation application of the terminal, or may be stored in a server corresponding to the map navigation application, and the following description will be given only by taking an example in which the electronic map is stored in a server corresponding to the map navigation application.
In practical application, most of the electronic maps stored in the server are realized based on geographic data provided by some large-scale service providers, and the large-scale service providers collect the geographic data through collection vehicles, because of the limitations of the collection vehicles, when the geographic data are collected, position information of some actual geographic scenes cannot be collected, so that if a path end point input by a user is not collected in the electronic map, when the terminal searches for the path information from the current position of the terminal (i.e., the geographic position where the terminal is currently located) to the input path end point in the server, the corresponding path information cannot be accurately searched, that is, the path information cannot be accurately displayed in the electronic map displayed by the map navigation application.
However, in general, no matter whether the electronic map provides accurate path information, the user may want to reach the path end point by a method, and therefore, in the embodiment of the present application, if the terminal does not find the path information from the current position of the terminal to the input path end point in the server, the terminal may continuously collect the position information of the terminal in the process that the user reaches the path end point, so as to obtain the accurate path information from the path start point to the path end point. Specifically, when the terminal does not find the path information from the current position of the terminal to the path end point, the current position of the terminal can be used as the path starting point, and the collection of the position information of the terminal itself is started, wherein the terminal can continuously collect a plurality of position information of the terminal itself, and meanwhile, when the terminal does not find the path information from the current position of the terminal to the path end point in the server, the current position can be used as the path starting point, and the time for collecting the position information can also be recorded from the current moment.
In the process that the terminal collects the plurality of position information of the terminal, the terminal can continuously collect the current position information of the terminal at random time intervals (for example, the time interval from the second time of collecting the current position information of the terminal to the third time of collecting the current position information of the terminal is 3 seconds, and the time interval from the third time of collecting the current position information of the terminal to the fourth time of collecting the current position information of the terminal is 5 seconds, that is, the time interval from the third time of collecting the current position information of the terminal to the fourth time of collecting the current position information of the terminal is random).
Continuing the above example, when the mobile phone receives the "building 321 of the cell 39 in beijing city" (i.e. the route end point) input by the distributor, and searches the route information from the logistics site (i.e. the current position of the mobile phone itself) to the "building 321 of the cell 39 in beijing city" in the server, since the collection vehicle cannot enter the inside of the cell 39 in beijing city, all the geographic position information data in the cell in beijing city is not collected by the collection vehicle, that is, all the geographic position information in the cell in beijing city is not collected on the electronic map, therefore, the map navigation application does not find the route information from the logistics site to the "building 321 of the cell 39 in beijing city", the mobile phone can use the logistics site as the route start point, use the building 321 of the cell 39 in beijing city as the end point ", and start to collect the own position information of the mobile phone, at the same time, and recording the time of position information acquisition from the current moment.
Assuming that the mobile phone collects the current position information of the mobile phone at random time intervals when collecting the position information of the mobile phone, namely, the time interval of each collection is not fixed, when a distributor moves forward 3 seconds from a logistics site to a building 321 of a cell 39 # of Beijing city, the mobile phone collects the current position information of the mobile phone, namely the position information of a geographic position A (39 degrees 8 minutes of northern latitude and 116 degrees 6 minutes of east longitude), when the distributor moves forward 3 seconds, the mobile phone collects the current position information of the mobile phone, namely the position information of a geographic position B (39 degrees 8 minutes of northern latitude and 116 degrees 7 minutes of east longitude), when the distributor moves forward 5 seconds, the mobile phone collects the current position information of the mobile phone, namely the position information of a geographic position C (39 degrees 8 minutes of northern latitude and 116 degrees 9 minutes of east longitude), the mobile phone collects the current position information all the time according to the collection mode, when the position information is collected, the time taken by a distributor to reach the No. 39 building 321 of a certain cell in Beijing is recorded all the time, and the mobile phone stops collecting the position information of the mobile phone and recording the time for collecting the position information until the mobile phone receives a destination arrival instruction input by the distributor.
S103: and when the terminal receives an end point reaching instruction input by a user, the terminal sends the path starting point, the path end point and the collected position information to the server, so that the server generates and stores the path information from the path starting point to the path end point according to the received position information.
In the embodiment of the application, the terminal collects the self position information from the path starting point continuously, when the user reaches the path end point, an end point reaching instruction can be input on the terminal, when the terminal receives the end point reaching instruction input by the user, the collection of the self position information can be stopped, meanwhile, the collection time of the position information is also stopped, the path starting point, the path end point, the collected position information and the time taken by the user to reach the path end point are sent to the server, and the server can generate the path information from the path starting point to the path end point according to the received position information and store the path information in the storage area of the server.
Continuing the above example, after the distributor arrives at the building 321 of the cell 39 in beijing, the mobile phone inputs an end point arrival instruction, the mobile phone immediately stops collecting the position information of the distributor, stops recording the time of collecting the position information, and sends the logistics site, the building 321 of the cell 39 in beijing, the collected position information and 30 minutes (namely, the time of the distributor arriving at the building 321 of the cell 39 in beijing) to the server, and the server generates path information from the logistics site to the building 321 of the cell 39 in beijing according to the received position information and stores the generated path information in the server.
Through the steps, when the collection vehicle cannot collect the path information, the terminal of the user can collect the position information in the process that the user with the terminal goes to the path end point, the server generates and stores the path information from the path starting point to the path end point according to the position information, and then the navigation service from the path starting point to the path end point can be provided.
In step S102, the terminal continuously collects the current position information of the terminal at random time intervals, and it should be noted that the time intervals may also be preset (for example, the terminal collects the position information of the terminal once every 5 seconds), and specifically, the terminal periodically collects the position information of the terminal according to the preset time intervals.
In addition, in the embodiment of the present application, a user may all use a certain transportation mode (e.g., walking, riding, public transportation, etc.) to go from a route starting point to a route ending point, and in order to improve accuracy of navigation, that is, to provide route information and also provide a transportation mode, in the embodiment of the present application, when the terminal sends the route starting point, the route ending point and each piece of position information collected by the terminal to the server, the transportation mode used by the user may also be sent to the server. Specifically, after the terminal does not find the route information from the current position of the terminal to the route end point in the server, the terminal can prompt the user to select a traffic mode going to the route end point, after receiving the traffic mode selected by the user, the terminal starts to collect the position information of the terminal, stops collecting the position information until receiving an end point arrival instruction input by the user, and sends the route start point, the route end point, the collected position information and the traffic mode to the server.
Continuing the above example, in the above example, the mobile phone defaults itself to the current position as the starting point of the route (i.e., the logistics site) while receiving the "building 321 of a certain cell 39 in beijing city" (i.e., the end point of the route) inputted by the distributor, and the path information from the building 321 with the number 39 of a certain cell in Beijing city to the logistics site is searched in the electronic map stored by the server, but the path information is not searched, then the delivery staff is prompted to select the transportation mode to be adopted when the user goes to the logistics site, the delivery staff selects 'bicycle' according to the prompt, after the mobile phone receives the transportation mode selected by the delivery staff, the self position information of the mobile phone is collected, when a distributor arrives at a No. 39 building 321 of a certain cell in Beijing, when a destination arrival instruction is input into the mobile phone, the mobile phone immediately stops collecting position information of the mobile phone, and sends the position information of a certain cell 39 building 321 in Beijing city, the logistics site, the collected position information and the traffic mode 'bicycle' to the server together. Subsequently, if the server provides the route information from the logistics site to the building 321 of the cell 39 in beijing city for other users, the server can provide the recommended transportation mode 'bicycle' in addition to the stored route information.
The above is a first method for acquiring path information provided by the present application, and it should be noted that in the first method for acquiring path information, after a terminal receives a path start point and a path end point input by a user, and queries path information from the path start point to the path end point in a server, the terminal determines whether the path information returned by the server is accurate, that is, the terminal determines whether the server returns accurate path information from the path start point to the path end point, if the determination result is yes, the terminal does not need to acquire location information, otherwise, the terminal needs to acquire location information of itself. The judging method may specifically be: and judging whether the path end point input by the user is consistent with the path end point corresponding to the path information returned by the server, if so, indicating that the path information returned by the server is accurate from the path starting point to the path end point, and position information does not need to be collected, and if not, indicating that the path information returned by the server is not accurate from the path starting point to the path end point, and position information needs to be collected. That is, in the first method for acquiring path information, the terminal determines whether position information needs to be acquired.
The present application further provides a second method for acquiring path information, as shown in fig. 2.
Fig. 2 is a second process for acquiring path information according to the embodiment of the present application, which specifically includes the following steps:
s201: and the server receives the current position and the path end point of the terminal sent by the terminal.
In this embodiment of the application, when using the map navigation service, a user may open a map navigation application in a terminal, and input a route end point on a map navigation application interface in the terminal, and after receiving the route end point input by the user, the terminal determines a current geographic position of the terminal, and then sends the current geographic position and the route end point of the terminal to a server (as in the example in S101), that is, the server receives the current geographic position and the route end point of the terminal sent by the terminal.
S202: and when the path information from the current position of the terminal to the path end point is not found, sending a path information acquisition instruction to the terminal to enable the terminal to acquire the position information of the terminal.
In the embodiment of the application, after receiving the current position and the path end point of the terminal sent by the terminal, the server can determine whether the electronic map stored by the server has the path information from the current position of the terminal to the path end point, if so, the server returns the path information from the current position of the terminal to the path end point to the terminal, and if not, the server returns a path information acquisition instruction to the terminal, wherein the path information acquisition instruction is used for indicating the terminal to start to acquire the position information of the terminal and indicating the terminal to start to record the time for acquiring the position information.
For example, after the server receives (39 degrees 7 minutes in north latitude and 116 degrees 6 minutes in east longitude) and "39 th floor 321 in a certain cell in beijing city", the server searches for the path information (39 degrees 7 minutes in north latitude and 116 degrees 6 minutes in east longitude) from the electronic map stored in the server to the "39 th floor 321 in the certain cell in beijing city", and if the server does not find the path information (39 degrees 7 minutes in north latitude and 116 degrees 6 minutes in east longitude) from the "39 th floor 321 in the certain cell in beijing city", a path information acquisition instruction is sent to the mobile phone, so that the mobile phone starts to acquire the own position information, and meanwhile, the mobile phone starts to record the time for acquiring the position information.
S203: and receiving a path starting point, a path ending point and each piece of collected position information which are sent by the terminal, wherein the path starting point is the position when the terminal starts to collect the position information.
In the embodiment of the application, after receiving a path acquisition instruction sent by a server, a terminal starts to acquire a plurality of different position information of the terminal and records the time for acquiring the position information from the current moment, and after a user arrives at a path end point, an end point arrival instruction can be input on the terminal (the end point arrival instruction is used for indicating the terminal to stop acquiring the position information of the terminal and indicating the terminal to stop recording the time for acquiring the position information).
After receiving the route end point, the route start point, the collected position information and the time taken by the user to reach the end point (the time can be used for providing the shortest route for the user subsequently by the server), which are sent by the terminal, the server can perform corresponding processing on the received position information, wherein the route start point refers to the position when the terminal starts to collect the position information of the terminal.
S204: and generating and storing path information from the path starting point to the path end point according to the received position information.
In this embodiment of the application, the server may perform end-to-end connection on the received position information according to the collection sequence to generate path information from the path starting point to the path ending point, or may fit a piece of path information from the path starting point to the path ending point according to the received position information.
Through the steps, the server generates the path information from the path starting point to the path end point according to the position information collected by the terminal, enriches the path information and the electronic map in the server, and simultaneously can better provide map navigation service for the user.
Similar to the first method for acquiring path information, in order to provide more accurate navigation service for a user, after receiving a path information acquisition instruction sent by a server, a terminal may prompt the user to select a traffic mode to be adopted, the user may select a traffic mode (such as walking, riding, public transportation) on a mobile phone map navigation application interface, the terminal starts to acquire position information of the terminal after the user selects the traffic mode, and when the terminal receives an end point arrival instruction input by the user, the terminal may send the start point of the path, the end point of the path, the acquired position information and the traffic mode selected by the user to the server together, so that the server can subsequently provide path information from the start point of the path to the end point of the path and recommend a corresponding traffic mode.
In addition, in practical applications, although some users use the map navigation service, after the map navigation application does not return the route information to the terminal, the user does not necessarily go to the route end point immediately, and thus the position information of the user collected by the terminal is of no practical significance for the server to process the collected data, and the route information from the route start point to the route end point cannot be generated according to the received position information, so that the server sends a route information collection instruction to the terminal, and the terminal needs to be determined to meet the condition for collecting the route information before the terminal collects the position information of the user, where the condition for collecting the route information may be: and in a preset time period, the moving distance of the terminal is greater than a certain threshold value. For example, before the server sends the path information acquisition instruction to the terminal, the location of the terminal may be monitored, assuming that the preset time period is 3 minutes and the threshold is 100 meters, and if the distance that the terminal moves in 3 minutes is greater than 100 meters, it indicates that the terminal meets the condition of acquiring the path information, that is, the geographic location information acquired by the terminal is of practical significance for the server to process the acquired data.
Of course, the above-mentioned conditions for collecting the path information are not limited to this, for example, the conditions for collecting the path information may also be: the method comprises the steps that a user attribute of map navigation application is used as a specific attribute, the specific attribute comprises a distributor, a postman and other specific occupations, when a server does not find path information from a path starting point to a path end point, prompt information can be sent to a terminal to prompt a user to input the occupation of the user, the terminal returns the occupation input by the user to the server, if the server judges that the occupation input by the user is the distributor or the courier, the terminal is determined to meet the condition for collecting the path information, a path information collecting instruction is sent to the terminal, if the server judges that the occupation input by the user is not the distributor or the courier, the terminal is determined not to meet the condition for collecting the path information, and the path information collecting instruction is not sent to the terminal. Of course, the server may also determine whether the occupation of the user is a specific occupation such as a deliverer or a postman according to user information corresponding to an account pre-registered by the user.
In this embodiment, the server may process the received route start point, route end point and each piece of location information after receiving the route start point, route end point and each piece of location information transmitted by the terminal, and specifically, the server may generate route information from the route start point to the route end point according to each received information location, and update the electronic map or the route information stored in advance according to the generated route information. When updating the route information, the server may compare the generated route information with the route information on the electronic map, determine a portion that does not overlap with the route information on the electronic map in the generated route information, and update the electronic map with the determined portion of the route information. Of course, the generated path information may be directly stored in a separate database.
For example, after receiving the position information, the server connects the position information end to end in the collection order, as shown in fig. 3, and the path information on the electronic map is as shown in fig. 4, and the server compares the path information shown in fig. 3 with the path information shown in fig. 4, and determines a part which is not overlapped with the path information shown in fig. 4 in the path information shown in fig. 3, that is, the part of the path information from the geographic position B to the geographic position C in the path information shown in fig. 3 is not overlapped with the path information shown in fig. 4, so that the part of the path information from B to C is updated to the electronic map, and at the same time, the path information shown in fig. 3 can be stored in an independent database.
Compared with the first path information acquisition method, in the second path information acquisition method, the terminal is not required to judge whether position information needs to be acquired or not, but the server judges according to the query result of path information from a path starting point to a path end point, and the terminal only needs to start acquiring the position information after receiving a path information acquisition instruction sent by the server and stop acquiring after receiving an end point arrival instruction input by a user.
The above are two path information collection methods provided by the present application, and in addition, the present application also provides a navigation method, as shown in fig. 5.
Fig. 5 is a navigation process provided in the embodiment of the present application, which specifically includes the following steps:
s501: and receiving a path starting point and a path end point input by a user.
S502: and searching the path information from the starting point to the end point of the path according to a pre-stored electronic map and the path information stored in a database, wherein the path information stored in the database is generated according to the self position information collected by the terminal in advance.
In the embodiment of the application, when using the map navigation service, a user may open a map navigation application in a terminal, and input a path start point and a path end point on a map navigation application interface in the terminal, and the terminal searches for path information from the path start point to the path end point in a pre-stored electronic map and a pre-stored database according to the input path start point to the path end point, where the electronic map may be stored locally in the terminal or in a server corresponding to the navigation application, and the path information stored in the database is collected in advance through the processes shown in fig. 1 and fig. 2 (that is, generated according to own location information collected by the terminal), and is independent of the electronic map.
For example, a distributor of a certain logistics site needs to distribute a piece of goods to a resident residing in a certain cell 39 th building 321 in beijing city, but since the distributor does not know the specific position of the certain cell 39 th building 321 in beijing city, the distributor opens a map navigation application in a mobile phone (i.e., a terminal), inputs a "logistics site" in an input box corresponding to a route starting point, inputs a "certain cell 39 th building 321 in beijing city" in an input box corresponding to a route ending point, and after receiving the route starting point and the route ending point input by the distributor, the mobile phone searches for route information from the "logistics site" to the "certain cell 39 th building 321 in beijing city" in an electronic map and a database stored locally.
S503: and navigating according to the path information searched from the database.
In the embodiment of the present application, after the route information is collected through the processes shown in fig. 1 and fig. 2, the route information may not be updated to the electronic map, but the route information may be stored in an independent database. That is, even if the terminal collects the route information from the route start point to the route end point, the electronic map cannot find the route information from the route start point to the route end point.
Therefore, in the embodiment of the present application, when the terminal does not find the path information from the path starting point to the path ending point in the pre-stored electronic map according to the path starting point to the path ending point input by the user, the terminal may directly search in the database storing the path information (the path information stored in the database is the path information acquired through the steps in the foregoing fig. 1 and fig. 2), and navigate the user according to the found path information, that is, provide the path information acquired through the processes shown in the foregoing fig. 1 and fig. 2 to the user, and navigate the user, thereby implementing multiplexing of the path information and multiplexing of the navigation.
For the example, it is assumed that path information from the "logistics site" to the "building 321 of the cell 39 in beijing city" is generated through the collected location information, and the path information is stored in the database, and after the mobile phone searches the path information from the "logistics site" to the "building 321 of the cell 39 in beijing city" in the electronic map stored locally, the mobile phone directly searches in the database in which the path information is stored, and navigates the user according to the searched path information.
In practical applications, there is a high possibility that not only the route information from the route start point to the route end point input by the user is not found in the electronic map, but also the route information from the route start point to the route end point is not found in the database storing the route information, however, since there is a possibility that the route information from the route start point to a certain position exists in the electronic map, and there is also a case that the route information from the certain position to the route end point exists in the database, in the present application, if the route information from the route start point to the certain position input by the user is not found in both the electronic map stored in advance and the database, the first route information from the route start point to the certain position (i.e., the first route information from the route start point to the route end point) can be found from the electronic map stored in advance, and searching and obtaining second path information from the position to the path end point (namely, the second path information from the path starting point to the path end point) from the database, forming the first path information and the second path information into the path information from the path starting point to the path end point, and navigating the user according to the formed path information.
Based on the same idea, the embodiment of the present application further provides two path information collection devices and a navigation device, as shown in fig. 6, 7, and 8.
