Embodiment 1

[0023] figure 1 It is a flow chart of a method for identifying a navigation route provided by Embodiment 1 of the present invention. The method of this embodiment can be performed by a navigation route identification device, which can be implemented by means of hardware and / or software, and can generally be integrated into a navigation client, and the method of this embodiment is generally applicable to navigation clients The client determines whether the user deviates from the navigation route. see figure 1 The identification method of the navigation route provided in this embodiment specifically includes the following:

[0024] S11. Display the current navigation route obtained from the navigation server.

[0025] Specifically, when a user needs to query a navigation route or perform route navigation, the navigation client sends a route navigation request including a navigation start point and a navigation end point to the navigation server, and the navigation server dete...

Embodiment 2

[0037] This embodiment provides a new method for identifying a navigation route on the basis of the first embodiment above. figure 2 It is a flow chart of a method for identifying a navigation route provided by Embodiment 2 of the present invention. see figure 2 The identification method of the navigation route provided in this embodiment specifically includes the following:

[0038] S21. Display the current navigation route acquired from the navigation server.

[0039] S22. Periodically acquire the location of the user terminal carrying the navigation client.

[0040] S23. Match the position of the user terminal based on the current navigation route, and if the matching is successful, determine the successfully matched position as a historical matching point of the current navigation route.

[0041] Wherein, the matching method may be a projection matching method. If the projection of the position of the user terminal falls on the current navigation route, it indicates t...

Embodiment 3

[0051] This embodiment provides a new method for identifying a navigation route on the basis of the first and second embodiments above. image 3 It is a flow chart of a method for identifying a navigation route provided by Embodiment 3 of the present invention. see image 3 The identification method of the navigation route provided in this embodiment specifically includes the following:

[0052] S31. Display the current navigation route and the candidate navigation route obtained from the navigation server.

[0053] Specifically, the navigation client sends a route navigation request including a navigation starting point and a navigation terminal to the navigation server according to user needs, and the navigation server determines at least two navigation routes according to the received navigation request. The navigation server may determine one current navigation route from the at least two navigation routes according to the user instruction sent by the navigation client a...

Abstract

The embodiment of the invention discloses a navigation route recognition method and device. The method comprises the steps that a current navigation route obtained from a navigation server is displayed; the position of a user terminal bearing a navigation client is obtained periodically; the direction of the user terminal is determined according to the obtained position of the user terminal; yaw recognition is conducted on the user terminal according to the position and direction of the user terminal. According to the technical scheme, yaw recognition is conducted based on two dimensions of the position and direction of the user terminal; compared with an existing yaw recognition method which achieves yaw recognition simply based on the position of the user terminal, the accuracy of yaw recognition is improved, and therefore the satisfaction degree of user experience is improved.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation route identification method and device. Background technique [0002] With the increasing popularity of GPS (Global Positioning System, Global Positioning System), more and more consumers can instantly obtain route planning information when driving or walking through their portable smart terminals. The basic process of the existing route navigation is: the user starts the navigation client software installed in the smart terminal, inputs the start position and the end position, and sends them to the corresponding navigation server, and the navigation server generates a navigation route based on the start and end position information and Return to the client software, and the client software guides the user's driving or walking according to the navigation route. [0003] Off-track recognition, also known as off-track calculation or off-track judgment, means that t...
