As background art, the existing navigation software or equipment generally selects a route around an interest point closest to the interest point as a navigation end point according to the interest point input by a user as a navigation end point, and plans an optimal path from a departure point to the navigation end point. However, if the user plans the route to the end point of the navigation in this way, the user may need to travel around the interest point or walk for a certain distance to reach the place that the user actually wants to go, which results in a very poor user experience.
Therefore, the embodiment of the invention provides a navigation method and a navigation device, which can provide a destination selectable list for a user to select according to interest points input by the user, and then perform route planning according to a navigation road selected by the user, so that the navigation method and the navigation device can help the user to set a navigation destination more reasonably and improve user experience.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Fig. 1 is a flowchart illustrating a navigation method according to an embodiment of the present invention. As shown in fig. 1, the navigation method includes the following steps:
s10: obtaining an interest point;
s11: acquiring coordinate information of the interest point;
s12: acquiring road information in a first range around the coordinate information of the interest point;
s13: providing a selectable list of destinations;
s14: planning a route according to a user-selected navigation road
In the implementation of step S10, the points of interest input by the user are acquired. Specifically, the user inputs the point of interest into the navigation apparatus through an input device, which may be a touch screen, a voice recognition unit, or a keyboard input unit. Accordingly, the user input interest point may be input by handwriting or voice. For example, the user inputs the point of interest "place square" by voice.
In the implementation of step S11, the coordinate information of the point of interest is obtained by identifying the point of interest input by the user, searching for the location where the point of interest information is located. Specifically, searching the location of the point of interest information includes: after receiving the interest point information input by the user, the navigation device acquires the position of the interest point information, namely the coordinate information of the interest point, according to the input interest point information. The obtaining mode can adopt a mode synchronous with the cloud server, namely the navigation device receives the interest point information input by the user and then transmits the information to the cloud server, and the cloud server sends the position of the interest point information to the navigation device, so that the navigation device obtains the position of the interest point information; the obtaining method may also be that the position of the commonly used point of interest information (such as a mall, an office building, a cell, a gas station, etc.) is stored in the navigation device in advance, and after the navigation device receives the point of interest information input by the user, if the point of interest information is the commonly used point of interest information, the position of the point of interest information stored in the navigation device is directly called.
In the implementation of step S12, road information in a first range around the point of interest coordinate information is acquired. Optionally, the first range includes: and a circular range with the coordinate information of the interest point as a circle center and the radius as a first threshold value. For example, if the point of interest input by the user is "place square", the location information of the point of interest "place square", that is, the coordinate information, is obtained: shanghai city Nanjing east No. 409 of Huangpu district; then, taking the coordinate information as a circle center, acquiring road information in a circular range with the radius as a first threshold value: nanjing Dong road, Nanjing foot street, Jiujiang road, Shanxi south road, Fujian middle road, Tianjin road, Hankou road, Ningbo road, Shandong middle road, Henan middle road, etc.
Optionally, the first threshold is 500 meters, and the first threshold may be changed. Specifically, the first threshold is set to an initial value, for example, the first threshold is set to 500 meters. The user may modify the first threshold according to the user's own needs, for example, the user may modify the first threshold to 1000 meters. By modifying the first threshold range, the search range can be expanded, i.e., the road information can be searched over a larger range.
In other embodiments, the first range may also be a rectangular or square area centered on the coordinate information of the interest point, and a side length of the rectangular or square area may be changed according to an actual requirement.
In the implementation of step S13, a destination selectable list is provided according to the road information within the first range around the point of interest coordinate information acquired in step S12. Optionally, the destination selectable list includes all road names within the first range of points of interest. Optionally, the destination selectable list further includes: the shortest straight-line distance of all roads in the first range of the interest point relative to the interest point. For example, if the point of interest input by the user is "place square", and the first threshold is set to 500 meters, the selectable destination list composed of road information with a radius of 500 meters and a center of the point of interest "place square" is shown in table 1 below:
TABLE 1
It should be noted that the road names and the distance data in table 1 are only exemplary descriptions, and are not actual map information.
Optionally, the destination selectable list further includes: a bearing of the road relative to the point of interest. Optionally, the orientation comprises: south, north, west, east, southeast, southwest, northeast, and northwest. For example, the Jiujiang road in Table 1 is located south of the point of interest "Place Square", and the Shanxi-south road in Table 1 is located east of the point of interest "Place Square". In embodiments of the invention, the position of the road relative to the point of interest is not shown in table 1, in other embodiments, the position of the road relative to the point of interest may be shown in table 1.
Optionally, all the roads in the first range of the interest point in the destination selectable list are arranged in order from near to far of the straight-line distance of the road from the interest point. As shown in table 1, roads within a range of 500 meters in radius from the point of interest "place square" as the center are displayed in table 1 in order from near to far from the point of interest.
Referring to fig. 2, in the implementation of step S14, the planning of the route according to the navigation road selected by the user includes the following steps:
s140: acquiring a navigation road selected by a user;
s141: determining a projection point of the interest point closest to the navigation road, wherein the projection point is a final destination;
s142: determining coordinate information of the projection point;
s143: and planning a route according to the coordinate information of the projection point.
In the implementation of step S140, the user selects a navigation road from the destination selectable list through an input device, which may be a touch screen, a voice recognition unit, or a keyboard input unit. Accordingly, the user's selection of the navigation road may be through handwriting input or voice input. For example, the user selects "jiujiang road" as the navigation road from table 1 by voice.
In the implementation of step S141, a projection point of the interest point closest to the navigation road is determined, and the projection point is the final destination. Wherein determining the closest projected point of the point of interest on the navigation road comprises: calculating the shortest distance from the reference point to the navigation road by taking the point corresponding to the coordinate information of the interest point on the map as the reference point; the navigation road comprises a plurality of straight line segments which are connected together, the position with the shortest distance from the reference point to each straight line segment is calculated, the position with the shortest distance is the projection point of the interest point on each straight line segment, and the distance from the interest point to each projection point is the projection distance; and in all the projection distances, the position corresponding to the shortest projection distance is the projection point from the interest point to the navigation road.
Fig. 3 is a schematic view of an application scenario for determining a projected point of a point of interest on a navigation road according to an embodiment of the present invention. Referring to fig. 3, a "place square" is taken as an interest point, and a "jiujiang road" is taken as a navigation road for explanation. The navigation device acquires the interest points as 'place squares', acquires coordinate information of the 'place squares' through a cloud server or common interest point information stored in the navigation device, and is represented by a point A in fig. 3, then acquires road information in a first range of the 'place squares' of the interest points, displays the road information as a destination selectable list to a user (shown in reference table 1), and the user selects 'jiujiang road' from the destination selectable list as a navigation road. The navigation device acquires that the navigation road selected by the user is the 'Jiujiang road', then the navigation device projects the 'place square' of the interest point to the 'Jiujiang road' of the navigation road, and acquires the projection point, which is closest to the position information A of the 'place square' of the interest point, on the 'Jiujiang road' of the navigation road, which is represented by the point B in figure 3, wherein the projection point B is the final destination.
It should be noted that fig. 3 is only an exemplary illustration, and the interest points, the location information of the interest points, the road names and the distribution, and the like in fig. 3 are not actual map information.
In the implementation of step S142, the navigation device determines the position information of the projection point B, i.e. determines the coordinate information of the projection point B, according to the projection point B determined in step S141, through a cloud server or common point of interest information already stored in the navigation device.
In step S143, the navigation device sets the coordinate information of the projection point B determined in step S142 as a navigation destination, performs route planning using the navigation destination as a destination, and plans a route from a departure point set by the user to the navigation destination or from a current position of the user to the navigation destination.
