method for preparing a foodExamples of the embodiments
In order to realize route planning and provide environmental information around the route for the user to help the user to lift for preparing for a trip, the embodiment proposes a method for acquiring POI along the planned route, as shown in fig. 1, the method includes the following steps:
s200: and planning a route according to the starting point and the end point set by the user to provide a planned route.
S300: and according to the type of the target POI selected by the user, retrieving and displaying the selected type of the target POI along the planned route based on the corresponding association relationship between the point location ID of the preset target POI and the ID of each route in the planned route.
According to the embodiment, when the travel route is planned for the user, POI around the planned route can be retrieved in a classified mode through the corresponding association relation between the point position ID of the target POI and the ID of each route in the planned route, and the target POI which is interested by the user along the route is displayed for the user to preview or further select. Therefore, by adopting the method for acquiring the POI, the route planning can be completed, meanwhile, the environmental information around the route is provided for the user, the preparation before the user goes out is helped, and the efficiency and the safety of the going out are improved.
For example: when the place where the user wants to go is wide and sparse and the number of gas stations is small, the user can be reminded of needing to be filled with oil before going. Therefore, sufficient route information is mastered by previewing the POI distribution condition around the route in advance, and the planning and preparation work of travel is facilitated.
It should be noted that, in the above embodiment, the target POI refers to a POI desired to be queried selected by the user.
As an alternative embodiment, as shown in fig. 2, the method for obtaining POI along the planned route may further include the following steps:
s100: and a POI database is established in advance, and POI data information and the corresponding association relationship between the point location ID of the POI and the road route ID are recorded in the POI database.
As an alternative embodiment, the method for acquiring POI along planned route may further include the following steps:
s400: and setting a certain target POI as a route point according to the selection of the user. And automatically adding the route points into the planned route to guide the route for the user.
Therefore, the POI which is interested by the user is added into the planned route by the method of adding the passing point in the route planning, the route planning is not needed to be carried out again, the method is convenient and quick, and the user experience can be further improved. For example, if the user wishes to be guided to a designated POI, the user may choose to add a waypoint function, which will make a halfway destination, and the navigation will guide and display.
In an optional embodiment, in the S100, the step of building the POI database in advance may further include the steps of:
s102: and acquiring POI (point of interest) original data and processing the POI original data.
S104: and carrying out classification and naming on the processed POI data, and configuring a point location ID for the POI data.
S106: and establishing a corresponding association relationship between the point location ID of the POI and the road line ID associated with the POI.
Optionally, the step of establishing the POI database in advance may further include:
s108: and updating the data of the POI in the POI database and the corresponding association relationship between the point location ID of the POI and the associated road line ID periodically.
In an alternative embodiment, in S300, the step of retrieving and displaying the selected target POIs of the selected category along the planned route may further comprise the steps of:
s301: after the planning of the planned route is finished, according to the type of the target POI which is set by a user and is expected to be displayed on the planned route, the target POI of the corresponding type is found in the POI database through the road line ID of the planned route.
S302: and displaying the retrieved target POI on a route planning interface for a user to preview.
Generally speaking, in the process of planning and driving along a route, a general vehicle often needs to know the distribution situation of service facilities around the route in advance, and particularly in the process of long-distance driving, information of the environment around the route is particularly important for a user. In addition, route planning can be adjusted in a mode of setting the POI as a route point, and the method is convenient and fast. Therefore, the embodiments can help the user to make sufficient travel preparation in advance, and improve the efficiency and safety of travel.
In order to better understand the technical solutions of the above embodiments, the above embodiments of the method are further described herein with reference to the following examples:
in this example, the method for obtaining a POI along a planned route may comprise the processing steps of:
1. route planning
1.1 setting a starting point, and three setting modes are as follows:
1) automatically setting the current position as a starting point; 2) manually inputting (voice or text) a search setting starting point; 3) a starting point is selected on the map interface.
1.2 setting the destination by the following setting modes:
1) a user inputs (voice or text) a manual search destination; 2) selecting points on a map;
1.3 according to the starting point and the end point set by the user, carrying out route planning according to a conventional method. When the route planning is completed, the planned route records the following information in the system:
| route of road | ID of road route |
| Beijing to Shanghai | 1,2,3,4,5 |
2. POI (Point of interest) classified retrieval
2.1 after the route planning is finished, POI information needing to be displayed on the route can be selected through POI classification information built in the navigation system. For example, the following POI information are classified:
| classification | Seed code |
| Gas station | A1 |
| Service area | A2 |
| WC | A3 |
| Bank | A4 |
| Dining accommodation | A5 |
| Parking lot | A6 |
| Scenic spot | A7 |
| Automobile repair plant | A8 |
2.2 the user selects the type of POI in the navigation system that he wishes to display on the planned route.
2.3 search mode
The POI is made as follows:
| POI name | POI species | POI_ID | ID of road route |
| Changping service area | A1 | 100001 | 1 |
When the POI is produced, the relation between the point location ID of the POI and the ID of the road line is recorded, after the route is planned, the POI corresponding to the type is found in the POI table through the ID of the road according to the type of the POI which is set in a user system and is expected to be displayed on the route, and the POI is displayed on a route planning interface, so that the user can preview the whole route planning.
3. And the route point can be selected to add a route point function if the user wants to guide the established POI, the route point can be used as a midway destination, and the navigation can be guided and displayed according to the route point.
4. Ending navigation
The user may end the navigation part way through or the system may end the navigation by determining the actual location of the user and comparing the location on the map when guiding the user to the intended destination.
Therefore, while providing detailed route planning for the user, the embodiment can also perform classified retrieval and display on the peripheral POI information on the planned route according to the preference of the user, directly display the POI information required by the user on the navigation interface, and meanwhile, if the user wants to stop at a certain POI position, add the POI position point as a passing point, and the passing point can be automatically added into the route planning to guide the user.
