[0026] figure 1 It is a schematic flowchart of a route display method based on AR-HUD navigation according to an exemplary embodiment.

[0027] Please refer to figure 1 , a method for displaying a route based on AR-HUD navigation in this embodiment, comprising the following steps:

[0028] In step S1, the navigation data of the navigation route, the navigation data of the distance offset, the corresponding slope and the rotation are obtained.

[0029] Wherein, this step is to obtain the navigation data of the road, so as to facilitate the processing of the navigation data in the next step. Navigation data is obtained from existing navigation applications, such as common navigation applications such as Google Maps, Gaode Maps, and Baidu Maps. The obtained navigation data includes the distance offset and the corresponding slope and rotation. The obtained navigation data is to solve the problem that the navigation track cannot be generated in real time according to the slope a...

Abstract

The invention discloses a path display method and system based on AR-HUD navigation, and a computer storage medium, and belongs to the technical field of vehicle navigation, and the method comprises the steps: S1, obtaining navigation data of a navigation path, wherein the navigation data comprises the distance offset and the corresponding gradient and rotation degree; S2, generating key points ofthe navigation path according to the navigation data, and calculating three-dimensional positions of the key points under vehicle body coordinates; and S3, drawing a three-dimensional graph of a navigation arrow according to the three-dimensional position, and projecting the three-dimensional graph to a head-up display. In the prior art, a navigation track cannot be generated in real time according to a gradient and a rotation degree and the navigation arrow is not fit with an actual road condition, in order to solve the technical problem, the invention provides the path display method and system based on AR-HUD navigation and the computer storage medium, and the navigation path fit with the actual road condition can be dynamically displayed by a plurality of navigation arrow icons, so that the display is more intuitive.

Description

technical field [0001] The present invention relates to the technical field of vehicle navigation, in particular to a route display method, system and computer storage medium based on AR-HUD navigation. Background technique [0002] The continuous development of automobile technology makes people more and more closely connected with automobiles, and the demand for various functions of automobiles is also increasing. In the existing vehicle navigation technology, most of the navigation is performed through the application program installed in the vehicle system. Another method is to collect the scene images captured by the vehicle in real time, and then mark the corresponding arrows on the collected images to indicate the road ahead of the vehicle. However, this method requires the driver to look at the navigation information on the screen of the vehicle. It is easy to distract the driver's attention and drive unsafely. [0003] In the prior art, AR-HUD technology is gradua...
