Problems solved by technology
[0003] The existing navigation guidance method has the following disadvantages: first, the distance prompt is not easy for users to judge, especially for users who are not sensitive to distance, and it is not intuitive
Second, due to the viewing angle, it is difficult for users who are unfamiliar with the road to accurately estimate the distance
Third, the existing navigation guidance method is too different from the daily guidance habits, not specific enough, not intuitive enough, not friendly enough
Therefore, the existing navigation guidance method cannot help the user to accurately judge the walking path, thus causing the user to face the risk of going the wrong way

Embodiment 1
[0095] Figure 4 It is a schematicflowchart of the navigation method provided by Embodiment 1 of the present invention. Such as Figure 4 As shown, the navigation method includes the following steps:
[0096]S401. According to the set start point and end point of the itinerary and the topological relationship of the road, plan a guiding path from the start point to the end point.
[0097] S402. According to the guidance route and the current positioning position, acquire the first turning intersection currently to be guided.
[0098] S403, judging whether the first turning intersection reaches at least one broadcast condition preset by a specific guidance voice:
[0099] As mentioned above, in the embodiment of the present invention, there are many types of specific guidance voices, as examples, it specifically includes: landmark voice, traffic light voice, T-junction voice, multi-intersection voice, reference traffic light voice and crossroad voice. When the first turnin...

[0171] Figure 7 It is a schematic structural diagram of the navigation device provided by Embodiment 2 of the present invention. Such as Figure 7 As shown, the navigation device includes the following units:
[0172] A guiding path planning unit 71, configured to plan a guiding path from the starting point to the ending point according to the starting point and the ending point of the set trip and the topological relationship of the road;
[0173] An acquisition unit 72, configured to acquire the first turning intersection currently to be guided according to the guidance path and the current positioning position;
[0174] Judging unit 73, for judging whether the first turning intersection reaches the broadcast condition preset by the specific guidance voice;
[0175] A determining unit 74, configured to determine the specific guidance voice whose broadcast condition is met as the specific guidance voice matching the first turning intersection;
[0176] In addition, the n...

Abstract
The present invention discloses a navigation method and a navigation device. The method comprises the steps of according to the starting point and the ending point of a travel route, and the road topology relationship, planning a guide route from the starting point and the ending point; according to the guide route and the current location, obtaining a current to-be-guided first turning intersection; judging whether the first turning intersection meets a broadcasting condition preset by a particular guiding voice; confirming the particular guiding voice to be a particular guiding voice matched with the first turning intersection when the first turning intersection meets the broadcasting condition; according to broadcasting contents and voice broadcasting rules corresponding to the particular guiding voice matched with the first turning intersection, generating a voice text of the first turning intersection and broadcasting the voice text. According to the technical scheme of the invention, the guiding voice provided in the navigation method is more intuitive and more friendly. Therefore, users can make accurate judgment on the route, so that the risk of going wrong ways is reduced.
Description
technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and device. Background technique [0002] With the improvement of living standards, the development of technology, and the popularization of smart terminals, people rely more and more on navigation tools for travel. The navigation tool can guide the user how to walk by playing a guiding voice. In the navigation guidance process of the existing navigation tools, the conventional guidance voice adopted at the crossing that needs the user to turn is such as "turn left at the end of the road 500 meters ahead, and guide towards the railway station". It can be seen that the key points broadcast by the conventional guidance voice for the intersection are mainly the distance and the turning action at the intersection. [0003] The existing navigation guidance method has the following disadvantages: first, the distance prompt is not easy to judge for users, especi...
