[0037] figure 2 It is a flow chart of a navigation route push method in the first embodiment of the present invention. The method in this embodiment can be executed by a navigation route push device, which can be implemented by hardware and / or software, and generally can be integrated into the In the server where the client pushes the navigation route, it is used in conjunction with the client that completes the route navigation. The method of this embodiment specifically includes the following operations:

[0038] 210. The server acquires a difference route and an overlapping route index between the off-course replanned route and the original navigation route.

[0039] In this embodiment, the client may yaw multiple times, and the original navigation route is the navigation route used by the client before the yaw; The current location of the client, and the re-determined navigation route for the client.

[0052] Figure 4 It is a flowchart of a method for pushing a navigation route according to the second embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, it is preferable to optimize the differential route and overlapping route index between the yaw replanned route obtained by the operation server and the corresponding original navigation route as follows: Replanned road section data and original road section data respectively corresponding to the yaw replanned route and the original navigation route, wherein at least two road section identifiers corresponding to the route are sequentially stored in the road section data; the server acquires the replanned In the road section data, the road section identifiers that do not overlap with the original road section data are used as differential routes, and an overlapping route index is determined according to the initially overlapping road section ide...

[0068] Figure 6 It is a flowchart of a method for pushing a navigation route according to the third embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, preferably, among the re-planned road segment data acquired by the operation server, the road segment identifiers that do not overlap with the original road segment data are used as differential routes, and according to the The initial overlapping road section identification between the replanned road section data and the original road section data determines that the overlapping route index is optimized as:

[0069] The server respectively obtains the last road section identifier from the replanned road section data and the original road section data, and performs comparison as the current comparison identifier;

[0070] If the current comparison identifier in the replanned road section data is inconsistent with the current comparison identifi...

Abstract

The embodiment of the invention discloses a navigation route pushing method and device and a navigation route generating method and device. The navigation route pushing method comprises the following steps: a server obtains a different route and overlapping route index between a yaw re-planning route and a corresponding original navigation route; the server provides the different route and overlapping route index for a client to indicate the client to correct the original navigation route according to the different route and overlapping route index so as to generate a yaw re-planning route of the client. The navigation route pushing method solves the technical problems that the conventional navigation product can abandon the original route and receive all information of a new route sent by a server again during yaw re-planning every time; as a result, network flow is wasted, and the response time of online service is influenced. The navigation route pushing method optimizes the conventional navigation technology, meets the increasing efficient and convenient navigation demands of people, reduces information transmission quantity of route data in the yaw re-planning process, and shortens the response time of the client.

Description

technical field [0001] Embodiments of the present invention relate to navigation technology, and in particular, to a method and device for pushing a navigation route, and a method and device for generating a navigation route. Background technique [0002] With the continuous development of communication technology and terminal technology, terminal equipment integrates more and more functions. Correspondingly, various kinds of applications (APP, Application) are also continuously developed and used, which greatly enriches and facilitates people's life. Among them, some applications will use LBS (Location Based Service, location-based service), also known as location service. Currently commonly used LBS applications mainly include: Baidu Navigation or AutoNavi and other products used for destination navigation. [0003] Existing navigation applications, after the navigation user inputs the navigation start point and navigation end point through the navigation client, will se...
