Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] refer to figure 1 , figure 1 It is a schematic diagram of a navigation image in the prior art. Such as figure 1 The navigation image shown is different from what the driver actually sees. This navigation method is not intuitive enough for the driver, which makes the driver unable to accurately understand the navigation intention referred to by the navigation image, thus There is a case of going the wrong way.

[0052] In order to solve this technical problem, the embodiment of the present invention proposes an AR navigation method. Through this embodiment, the navigation guide arrows are directly superimposed on the real-scene image captured by the vehicle camera to form an AR navigation image, so that the driver's eyes see The scene outside the car is the same as the scene in the AR navigation image displa...

Abstract

The invention provides an AR navigation method and device, and the method comprises the steps: obtaining the position positioning information of a vehicle, and determining the current lane of the vehicle according to the position positioning information; determining a standard lane according to the position positioning information and the navigation path planning information of the vehicle; acquiring a live-action image shot by a camera of the vehicle; determining the current lane in the live-action image, and determining the standard lane in the live-action image; and superposing a guide arrow pointing to the standard lane from the current lane on the live-action image to obtain an AR navigation image, and displaying the AR navigation image on a display screen of the vehicle. According tothe invention, the AR navigation image is used for guiding the driving direction of the driver, the driving direction is more intuitive, and the driver can understand the navigation intention indicated by the AR navigation image more easily, so that the situation of wrong road walking is avoided.

Description

technical field [0001] The present invention relates to the technical field of vehicle navigation, in particular to an AR navigation method and device. Background technique [0002] In view of the complexity of urban roads, many drivers will use navigation software to navigate the driving path when traveling. For example, the XX map APP is used for navigation. The APP provides users with driving route information, and users can conveniently drive according to the navigation map displayed on the mobile phone or on the car. However, for novice drivers, due to the difference between the display screen corresponding to the navigation map and the actual driving environment, it is easy to go the wrong way when encountering an environment with complex road surfaces such as intersections. Contents of the invention [0003] The main purpose of the present invention is to provide an AR navigation method and device, aiming to solve the above-mentioned technical problems existing in ...
