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...
Embodiment 2
[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 invention discloses a navigation method and device. The method includes: planning a guiding path from the starting point to the ending point according to the starting point and the ending point of the set itinerary and the topological relationship of the road; position, to obtain the first turning intersection currently to be guided; determine whether the first turning intersection reaches the broadcast condition preset by the specific guidance voice; determine the specific guidance voice whose broadcast condition is reached as matching the first turning intersection The specific guidance voice; according to the voice broadcast content and voice broadcast rules corresponding to the specific guidance voice matching the first turning intersection, generate the voice text of the first turning intersection and broadcast it. The guiding voice in the navigation method is more intuitive and friendly, enabling the user to make accurate judgments on the route and reducing the risk of going the wrong way.
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...
