Problems solved by technology

[0006] 2. In the existing 3D navigation technology, the concept of 3D guiding line determined according to the driving direction is not proposed, and the matching 3D guiding path cannot be planned from the 2D navigation path, and the corresponding relationship between 2D and 3D positions can be established to realize Two-dimensional and three-dimensional synchronous navigation;
[0007] 3. In the existing 3D navigation technology, there is no 3D navigation that generates a 3D scene from the perspective of the driver and is equipped with a 3D guiding path;
[0008] 4. In practical applications, the above 2 and 3 technologies are not used to realize the 3D navigation device synchronized with the 2D navigation

Abstract

The present invention provides a method of three-dimensional directional navigation synchronizing with two-dimensional navigation and an apparatus thereof. Based on the locations of departure and destination set by a user, planning a two-dimensional navigation path by using a two-dimensional electronic map database, and establishing a corresponding three-dimensional induced path according to a three-dimensional inducing line and a matched relational database; positioning and calculating corresponding locations on the three-dimensional induced path according to the current position on a two-dimensional navigation path and the matching relationship of the two-dimensional navigation path and the three-dimensional navigation path; and uploading the visible object set of the three-dimensional inducing line, rendering a three-dimensional scene, and performing two-dimensional navigation and / or three-dimensional navigation on the navigation apparatus. According to the present invention, the method and apparatus allow the user to identify the navigation map more easily, intuitively and accurately, and get more realistic and comfortable three-dimensional navigation experience.

Description

Technical field: [0001] The invention relates to the technical field of navigation, in particular to a three-dimensional directional navigation method and device synchronized with two-dimensional navigation. Background technique: [0002] In recent years, three-dimensional navigation maps of various concepts have become a hot spot in the field of navigation, especially in-vehicle navigation services. Drivers and passengers can identify landmarks and find the way forward through the 3D map. Although these two functions can be realized by superimposing partial pictures in the 2D navigation, the advantages of the 3D navigation map are more obvious and the visual effect is more realistic. [0003] However, the existing three-dimensional navigation maps all adopt the method of superimposing general three-dimensional road section pictures on the section of the road, and superimposing the enlarged intersection image on the intersection part of the road to generate a simple three-di...
