Problems solved by technology

The existing route re-planning methods have the following defects: (1) The interaction between the user and the electronic map is difficult. When the user determines the passing point on the electronic map, the user needs to touch repeatedly to select the passing point to be added on the electronic map , resulting in a cumbersome process of adding passing points; (2) According to the limited number of passing points selected by the user, the route that meets the user's wishes cannot be accurately planned, and there may be other planned routes, thereby reducing the accuracy of route planning and reducing user experience

Embodiment 1

[0025] figure 1 This is a flowchart of a route planning method provided in the first embodiment of the present invention. This embodiment is applicable to a situation in which a traveling route is planned according to a user's will. The method can be executed by a route planning device. The device can be implemented by hardware and / or software, and generally can be integrated into a server that provides route navigation services for electronic map products.

[0026] Generally, an electronic map navigation application can first receive a route planning request triggered by a user through human-computer interaction. The request contains the starting point and ending point of the route that the user wants to travel. When the route planned for the first time based on the route planning request does not meet the expected route, the user can start the self-planning mode of the traveling route. Therefore, the route planning method provided by the implementation of the present invention c...

Embodiment 2

[0040] figure 2 This is a flowchart of a route planning method provided in the second embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, it will be based on the pixel coordinate set and the pixel coordinates and the latitude and longitude coordinates. To determine the corresponding longitude and latitude coordinate set of the route trajectory in the geographic coordinate system, the specific optimization is: obtaining the longitude and latitude coordinates of the starting point and the end point of the route trajectory in the geographic coordinate system; according to the longitude and latitude of the starting point Coordinates, the first pixel coordinate in the pixel coordinate set, the longitude and latitude coordinates of the end point, and the last pixel coordinate in the pixel coordinate set, establish the correspondence between the latitude and longitude coordinates and the pixel coordinates...

Embodiment 3

[0062] FIG. 3 is a flowchart of a route planning method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the foregoing embodiment. In this embodiment, the coordinates of the route trajectory provided by the user on the terminal screen are obtained. The corresponding pixel coordinate set in the system is specifically optimized as: acquiring the sliding track formed by the user's touch and sliding on the terminal screen; extracting the sensing points that form the sliding track, where the sensing points include the start and end points of the sliding track ; Obtain a pixel coordinate set corresponding to the sensing point in the terminal screen coordinate system.

[0063] On the basis of the above optimization, the corresponding longitude and latitude coordinate set of the route trajectory in the geographic coordinate system will be determined according to the pixel coordinate set and the mapping relationship between the pixel coordinat...

Abstract

The invention discloses a method and an apparatus for route planning. The method includes the steps of: acquiring a pixel coordinate set corresponding to a user-provided route trace in a terminal screen coordinate system; according to the pixel coordinate set and a mapping relationship between the pixel coordinate and longitude and latitude coordinates, determining a longitude and latitude coordinate set that is corresponding to the route trace in a geographic coordinate system; according to the longitude and latitude coordinate set, determining a target planning route that is corresponding to the route trace. The method can achieve intelligent planning of a travel route on the basis of the user-provided route trace and solve a problem of inconsistence between route planning and a user expect route. Compared with a route planning method in the prior art, the method improves accuracy of route planning and improves the interaction manner between the user and an electronic navigation map. The method and the apparatus are easier to achieve interaction of custom information between the user and the electronic navigation map application.

Description

Technical field [0001] The embodiment of the present invention relates to the field of map technology, and in particular to a method and device for route planning. Background technique [0002] With the widespread application and development and innovation of computer technology, especially the emergence of smart terminal products, more and more application software appears in people’s lives. For example, based on video playback software installed on smart terminals, it can be used anytime, anywhere Watch the video; there are also various electronic map software that come out. Users only need to enter the origin and destination in the electronic map client to get the route planned for the user on the electronic map server, and provide users with navigation services. [0003] For users, in many cases, the route directly obtained based on the electronic map is not the route expected by the user. Generally, the route expected by the user may be the route planned by the user in advance...
