DESCRIPTION OF EMBODIMENTS
The following describes embodiments of the present disclosure in further detail with reference to the accompanying drawings and specific embodiments.
A terminal, as used herein, may refer to any appropriate user terminal with certain computing capabilities, such as a personal computer (PC) , a work station computer, a hand-held computing device (tablet) , a mobile terminal (amobile phone or a smart phone) , a smart terminal, or any other user-side computing device. A server, as used herein, may refer to one or more server computers configured to provide certain server functionalities. A server may also include one or more processors to execute computer programs in parallel.
Embodiment 1
As shown in FIG. 1, a route information acquiring method provided in an embodiment of the present disclosure includes the following steps:
Step 101: Enter a track change mode after displaying map information, to acquire current contact track information.
Herein, before the displaying map information, the method further includes: starting an electronic map application on a terminal to display, on a display interface, map information corresponding to an area in which a path to be planned by a user is located.
The entering a track change mode includes: after starting the map application, selecting, by the user, the track change mode according to a menu in the map application； and displaying, by the map application, the map information, and entering the track change mode. The track change mode is a mode in which the map information is unchanged, a touch operation of the user is received, and coordinate information obtained by using the touch operation of the user is used as route selection information.
The map information may be offline map information stored in the terminal in advance.
The offline map information is existing information in the background art, and may include road information, area information, connection information, and the like, where the road information may include information such as a road name, a road grade, and a road longitude-latitude coordinate string； and the area information may include information such as an area name, and a longitude-latitude coordinate string corresponding to each location in an area.
For example, as shown in FIG. 2, when a path to be planned by the user is a path whose start point is a point A and end point is a point B, a map including the point A and the point B needs to be displayed in a display area of a screen of the current terminal.
The acquiring current contact track information includes: sequentially collecting and recording, when detecting a touch operation, location coordinates corresponding to each contact； and using currently recorded location coordinates corresponding to all contacts as the current contact track information.
In some embodiments, the contact track information may further include a record time of each location coordinate.
The collecting location coordinates corresponding to a current contact may be: periodically collecting the location coordinates corresponding to the current contact, for example, performing one operation of collecting location coordinates corresponding to a contact during each clock cycle, where the location coordinates are collected coordinates of the current contact on a touch screen.
The current contact track information acquired in this embodiment may be that shown as a dashed line in FIG. 3. Specifically, when needing to reach a point B from a point A through a point C, the user may select a route from the point A to the point C on the screen, and then selects a route from the point C to the point B, so as to finally obtain the contact track information shown as the dashed line in FIG. 3.
Step 102: Convert the contact track information to geographic coordinate set information of a contact track.
Specifically, each piece of coordinate information among all coordinate information in the contact track information is matched with longitude-latitude information of a currently displayed map area to obtain longitude-latitude information corresponding to all the coordinate information, and all the longitude-latitude information is used as the geographic coordinate set information corresponding to the contact track.
For example, geographic coordinate set information corresponding to a contact track to be selected by the user is determined according to the contact track information shown as the dashed line in FIG. 3.
In some embodiments, the geographic coordinate set information corresponding to the contact track not only includes the longitude-latitude information, but also may include a record time corresponding to each piece of longitude-latitude information.
Step 103: Acquire road information from the map information according to the geographic coordinate set information corresponding to the contact track, generate route information by using the road information, and display the route information.
Specifically, for example, as shown in FIG. 3, when the geographic coordinate set information corresponding to the contact track is that shown as the dashed line, that is, the user selects a route from the point A to the point B through the point C, all the longitude-latitude information in the geographic coordinate set information corresponding to the contact track is grouped according to a record time sequence, where each group includes a specified number of pieces of longitude-latitude information；
a group is sequentially extracted as a current group, it is determined whether the current group has one or more pieces of corresponding road information, and if yes, the one or more pieces of road information is extracted； and if not, a next group is extracted as a current group until determining is completed on all groups； and
all extracted road information is joined to obtain joined road information, it is determined whether any two coordinate points having no corresponding road information exist between a start point and an end point of the joined road information, and if not, route information is generated by using the joined road information； and if yes, information of a road connecting the two coordinate points is selected from the map information, and route information is generated after the road information is added to the joined road information.
It can be seen that by using the foregoing method, a problem in the background art that route planning cannot be performed according to a user requirement during planning of route information can be solved, and a user can acquire an optimal path that meets a requirement of the user, thereby improving user experience.
Embodiment 2
As shown in FIG. 4, an operation process, on a terminal side, of a route information acquiring method provided in an embodiment of the present disclosure includes the following steps:
Step 401: A terminal enters a track change mode after displaying map information, to acquire current contact track information.
Herein, before the displaying map information, the method further includes: starting an electronic map application on the terminal to display, on a display interface, map information corresponding to an area in which a path to be planned by a user is located.
The entering a track change mode includes: after starting the map application, selecting, by the user, the track change mode according to a menu in the map application； and displaying, by the map application, the map information, and entering the track change mode. The track change mode is a mode in which the map information is unchanged, a touch operation of the user is received, and coordinate information obtained by using the touch operation of the user is used as route selection information.
The map information may be map information acquired by the terminal from a server when the terminal starts the electronic map application.
The map information is existing information in the background art, and may include road information, area information, connection information, and the like, where the road information may include information such as a road name, a road grade, and a road longitude-latitude coordinate string； and the area information may include information such as an area name, and a longitude-latitude coordinate string corresponding to each location in an area.
For example, as shown in FIG. 2, when a path to be planned by the user is a path whose start point is a point A and end point is a point B, a map including the point A and the point B needs to be displayed in a display area of a screen of the current terminal.
The acquiring current contact track information includes: sequentially collecting and recording, when detecting a touch operation, location coordinates corresponding to each contact； and using currently recorded location coordinates corresponding to all contacts as the current contact track information.
In some embodiments, the contact track information may further include a record time of each location coordinate.
The collecting location coordinates corresponding to a current contact may be: periodically collecting the location coordinates corresponding to the current contact, for example, performing one operation of collecting location coordinates corresponding to a contact during each clock cycle, where the location coordinates are collected coordinates of the current contact on a touch screen.
The current contact track information acquired in this embodiment may be that shown as a dashed line in FIG. 3. Specifically, when needing to reach a point B from a point A through a point C, the user may select a route from the point A to the point C on the screen, and then selects a route from the point C to the point B, so as to finally obtain the contact track information shown as the dashed line in FIG. 3.
Step 402: The terminal converts the contact track information to geographic coordinate set information of a contact track, and sends the geographic coordinate set information corresponding to the contact track to a server.
Specifically, each piece of coordinate information among all coordinate information in the contact track information is matched with longitude-latitude information of a currently displayed map area to obtain longitude-latitude information corresponding to all the coordinate information, all the longitude-latitude information is used as the geographic coordinate set information corresponding to the contact track, and the geographic coordinate set information corresponding to the contact track is sent to the server.
For example, geographic coordinate set information corresponding to a contact track to be selected by the user is determined according to the contact track information shown as the dashed line in FIG. 3.
In embodiments, the geographic coordinate set information corresponding to the contact track not only includes the longitude-latitude information, but also may include a record time corresponding to each piece of longitude-latitude information.
Step 403: The terminal receives route information from the server, and displays the route information.
It can be seen that by using the foregoing method, after acquiring an online map, a terminal sends, according to a requirement of a user, geographic coordinate set information corresponding to a route planned by the user； and in this way, route information that best meets the requirement of the user can be acquired.
As shown in FIG. 5, an operation process, on a server side, of a route information acquiring method provided in an embodiment of the present disclosure includes the following steps:
Step 501: After receiving geographic coordinate set information corresponding to a contact track, a server acquires corresponding road information from map information according to the geographic coordinate set information corresponding to the contact track, and generates route information by using the road information.
Specifically, the server finds, from map information stored by the server, one or more pieces of corresponding matched road information according to all longitude-latitude information in the geographic coordinate set information corresponding to the contact track, and generates route information by using the one or more pieces of road information.
Herein, the finding, from map information stored by the server, one or more pieces of corresponding road information may include:
for example, as shown in FIG. 3, when the geographic coordinate set information corresponding to the contact track is that shown as the dashed line, that is, a user selects a route from a point A to a point B through a point C, grouping, according to a record time sequence, all the longitude-latitude information in the geographic coordinate set information corresponding to the contact track, where each group includes a specified number of pieces of longitude-latitude information；
sequentially extracting a group as a current group, determining whether the current group has one or more pieces of corresponding road information, and if yes, extracting the one or more pieces of road information； and if not, extracting a next group as a current group until determining is completed on all groups； and
joining all extracted road information to obtain joined road information, determining whether any two coordinate points having no corresponding road information exist between a start point and an end point of the joined road information, and if not, generating route information by using the joined road information； and if yes, selecting, from the map information, information of a road connecting the two coordinate points, and generating route information after adding the road information to the joined road information.
Step 502: The server sends the route information.
Herein, the server sends the route information to the corresponding terminal according to an identifier of the terminal that sends the geographic coordinate set information corresponding to the contact track. A method for acquiring the identifier of the terminal by the server and a method for sending the route information by the server both belong to the background art, and are not described herein in detail.
It can be seen that by using the foregoing method, a problem in the background art that route planning cannot be performed according to a user requirement during planning of route information can be solved, and a user can acquire an optimal path that meets a requirement of the user, thereby improving user experience.

The touch display unit is specifically configured to: when detecting a touch operation, sequentially collect and record location coordinates corresponding to each contact； and use currently recorded location coordinates corresponding to all contacts as the current contact track information.
In some embodiments, the contact track information may further include a record time of each location coordinate.
The touch display unit is specifically configured to: periodically collect location coordinates corresponding to a current contact, for example, perform one operation of collecting location coordinates corresponding to a contact during each clock cycle, where the location coordinates are collected coordinates of the current contact on a touch screen.
The current contact track information acquired in this embodiment may be that shown as a dashed line in FIG. 3. Specifically, when needing to reach a point B from a point A  through a point C, the user may select a route from the point A to the point C on the screen, and then selects a route from the point C to the point B, so as to finally obtain the contact track information shown as the dashed line in FIG. 3.
The information processing unit is specifically configured to match each piece of coordinate information among all coordinate information in the contact track information with longitude-latitude information of a currently displayed map area to obtain longitude-latitude information corresponding to all the coordinate information, and use all the longitude-latitude information as the geographic coordinate set information corresponding to the contact track.
For example, geographic coordinate set information corresponding to a contact track to be selected by the user is determined according to the contact track information shown as the dashed line in FIG. 3.
In some embodiments, the geographic coordinate set information corresponding to the contact track not only includes the longitude-latitude information, but also may include a record time corresponding to each piece of longitude-latitude information.
The information processing unit is specifically configured to find, from the map information stored by the information processing unit, one or more pieces of corresponding matched road information according to all the longitude-latitude information in the geographic coordinate set information corresponding to the contact track, and generate route information by using the one or more pieces of road information.
The information processing unit is specifically configured to group, according to a record time sequence, all the longitude-latitude information in the geographic coordinate set information corresponding to the contact track, where each group includes a specified number of pieces of longitude-latitude information； sequentially extract a group as a current group, determine whether the current group has one or more pieces of corresponding road information, and if yes, extract the one or more pieces of road information, and if not, extract a next group as a current group until determining is completed on all groups； and join all extracted road information to obtain joined road information, determine whether any two coordinate points having no corresponding road information exist between a start point and an end point of the joined road information, and if not, generate route information by using the joined road information, and if yes, select, from the map information, information of a road connecting the two coordinate points, and generate route information after adding the road information to the joined road information.
It can be seen that by using the foregoing method, a problem in the background art that route planning cannot be performed according to a user requirement during planning of route  information can be solved, and a user can acquire an optimal path that meets a requirement of the user, thereby improving user experience.

Embodiment 4
As shown in FIG. 7, a terminal provided by an embodiment of the present disclosure may include: a touch display unit, an information processing unit, and a transceiver unit, where
the touch display unit is configured to: enter a track change mode after displaying map information, to acquire current contact track information, and receive and display route information；
the information processing unit is configured to convert the contact track information to geographic coordinate set information of a contact track, and send the geographic coordinate set information corresponding to the contact track to a server； and
the transceiver unit is configured to receive the route information from the server, and send the route information to the touch display unit.
The touch display unit is further configured to: when an electronic map application is started, display, on a display interface, map information corresponding to an area in which a path to be planned by a user is located. The map information may be map information acquired by the terminal from the server when the terminal starts the electronic map application. The map information is existing information in the background art, and may include road information, area information, connection information, and the like, where the road information may include information such as a road name, a road grade, and a road longitude-latitude coordinate string； and the area information may include information such as an area name, and a longitude-latitude coordinate string corresponding to each location in an area. 
The track change mode is a mode in which the map information is unchanged, a touch operation of the user is received, and coordinate information obtained by using the touch operation of the user is used as route selection information.
For example, as shown in FIG. 2, when a path to be planned by the user is a path whose start point is a point A and end point is a point B, a map including the point A and the point B needs to be displayed in a display area of a screen of the current terminal.
The touch display unit is specifically configured to: when detecting a touch operation, sequentially collect and record location coordinates corresponding to each current contact； and use currently recorded location coordinates corresponding to all contacts as the current contact track information.
In some embodiments, the contact track information may further include a record time of each location coordinate.
The touch display unit is specifically configured to: periodically collect the location coordinates corresponding to the current contact, for example, perform one operation of collecting location coordinates corresponding to a contact during each clock cycle, where the location coordinates are collected coordinates of the current contact on a touch screen.
The current contact track information acquired in this embodiment may be that shown as a dashed line in FIG. 3. Specifically, when needing to reach a point B from a point A through a point C, the user may select a route from the point A to the point C on the screen, and then selects a route from the point C to the point B, so as to finally obtain the contact track information shown as the dashed line in FIG. 3.
Specifically, each piece of coordinate information among all coordinate information in the contact track information is matched with longitude-latitude information of a currently displayed map area to obtain longitude-latitude information corresponding to all the coordinate information, and all the longitude-latitude information is used as the geographic coordinate set information corresponding to the contact track.
For example, geographic coordinate set information corresponding to a contact track to be selected by the user is determined according to the contact track information shown as the dashed line in FIG. 3.
In some embodiments, the geographic coordinate set information corresponding to the contact track not only includes the longitude-latitude information, but also may include a record time corresponding to each piece of longitude-latitude information.
It can be seen that, after acquiring an online map, a terminal sends, according to a requirement of a user, geographic coordinate set information corresponding to a route planned by the user； and in this way, route information that best meets the requirement of the user can be acquired.
When implemented in a form of a software functional module and sold or used as an independent product, the integrated module and a unit thereof in the embodiments of the present disclosure may also be stored in a computer-readable storage medium. Based on such an understanding, the technical solutions of the embodiments of the present disclosure essentially, or the part contributing to the background art may be implemented in a form of a software product. The computer software product is stored in a storage medium and includes several instructions for instructing a computer device (which may be a personal computer, a server, a network device, or the like) to perform all or a part of the methods described in the embodiments of the present disclosure. The foregoing storage medium includes: any medium that can store program code, such as a USB flash drive, a removable hard disk, a ROM, a RAM, a magnetic disk, or an optical disc. In this way, the embodiments of the present disclosure are not limited to any specific combination of hardware and software.

In some embodiments, the storage medium further includes an instruction that triggers at least one processor to execute the following operation, where the operation includes: periodically collecting the location coordinates corresponding to the current contact.

the processing unit is configured to: after receiving geographic coordinate set information corresponding to a contact track, acquire corresponding road information from map information according to the geographic coordinate set information corresponding to the contact track, and generate route information by using the road information； and
the transceiver unit is configured to send, to the processing unit, the received geographic coordinate set information corresponding to the contact track, and send the route information sent by the processing unit.
The processing unit is specifically configured to find, from the map information stored by the information processing unit, one or more pieces of corresponding matched road information according to all longitude-latitude information in the geographic coordinate set information corresponding to the contact track, and generate route information by using the one or more pieces of road information.
The processing unit is specifically configured to: for example, as shown in FIG. 3, when the geographic coordinate set information corresponding to the contact track is that shown as the dashed line, that is, a user selects a route from a point A to a point B through a point C, group, according to a record time sequence, all the longitude-latitude information in the geographic coordinate set information corresponding to the contact track, where each group includes a specified number of pieces of longitude-latitude information； sequentially extract a group as a current group, determine whether the current group has one or more pieces of corresponding road information, and if yes, extract the one or more pieces of road information, and if not, extract a next group as a current group until determining is completed on all groups； and join  all extracted road information to obtain joined road information, determine whether any two coordinate points having no corresponding road information exist between a start point and an end point of the joined road information, and if not, generate route information by using the joined road information, and if yes, select, from the map information, information of a road connecting the two coordinate points, and generate route information after adding the road information to the joined road information.
