Abstract

The embodiment of the invention discloses an AR navigation method and device, a vehicle device, a server and a medium. The method is executed by the vehicle device. The method comprises the steps of:obtaining vehicle position information; and environment road images collected by a vehicle image collector; according to the vehicle position information and each lane line track data included in a lane line network, determining a target lane line of a lane where the vehicle is located and the position of a target lane line in a world coordinate system; and according to the position of the targetlane line in the world coordinate system, drawing the lane line in the environment road images. According to the vehicle position information and each lane line track data, the target lane line and the position are accurately determined, the target lane line and the position are obtained from the lane line network to achieve timely and accurately obtain the lane line of the current lane in a condition that the lane line cannot be detected in real time, and the lane line is drawn in the environment road images for real-time display so as to improve the accuracy and the timeliness of the AR navigation.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Internet of Vehicles, and in particular, to an AR navigation method, device, vehicle-end equipment, server and media. Background technique [0002] Currently, users use navigation technology to provide driving guidance while driving a vehicle. Users can know their exact location and road conditions ahead through navigation technology. Among them, lane line recognition is one of the important positioning means in navigation technology. Through lane line recognition, the guide line can be fitted to the current road surface, and the lane condition of the current road surface can be accurately restored. [0003] Lane line detection generally obtains the road image through the image acquisition device during the driving process of the vehicle, and obtains the lane line of the current road through the road image detection. However, in scenes with limited vision, such as nighttime, backli...
