Description

Display method and device Technical Field The application relates to the field of intelligent vehicles, in particular to a display method and device. Background In order to improve driving safety, a Head Up Display (HUD) device may be used to present information required for driving at a position visible to the head up of the driver. The augmented REALITY HEAD up display (AR-HUD) can display information such as navigation instructions and the like in the visual field of a driver in a combined mode, so that the driver can acquire information required by driving more conveniently, conveniently and intuitively, and safety and comfort of driving are improved. However, during the running of the vehicle, the navigation instruction presented by the AR-HUD may not be accurate enough due to the excessively complex actual road conditions, and particularly, for an intelligent driving scenario, when the user cannot accurately learn the running intention of the vehicle based on the navigation instruction presented by the AR-HUD, a great unsafe feeling may be generated. Disclosure of Invention The application provides a display method and a display device, which can accurately transmit the driving intention of a vehicle to a user by attaching navigation elements to a planned path in a display area, thereby being beneficial to reducing complaints of the user on an intelligent driving function and improving the trust degree of the user on the intelligent driving function. In a first aspect, a display method is provided. The method comprises the steps of obtaining a planned path of a vehicle and a display area of a head-up display device, wherein the vehicle comprises the HUD, the display area of the HUD is used for displaying virtual images, determining the spatial position of a part of the planned path in the display area according to the planned path and the display area, and displaying navigation elements attached to the part of the planned path in the display area according to the spatial position. In the actual running process, the state of the road where the vehicle is located (such as the number of lanes, the gradient change condition of the road), the intersection condition of the road and other roads, the traffic rule of the road (such as steering and turning positions) and the like are often complicated. Especially in an intelligent driving scene, if the navigation element fails to accurately present navigation information to the user, the user can misunderstand the driving intention of the vehicle, if the user cannot accurately acquire the driving intention of the vehicle, the user can easily generate an uneasy emotion under complex road conditions and frequently take over the vehicle without taking over the vehicle, which not only can cause complaints of the user on the intelligent driving function, increase the untrusty feeling of the user on the intelligent driving function, but also can possibly jeopardize the driving safety of the vehicle. Moreover, even if the intelligent driving function is improved and upgraded for the entire vehicle manufacturer, such complaints and the sense of distrust of the user for the intelligent driving function cannot be reduced/eliminated. According to the method and the device for displaying the navigation elements, the navigation elements are attached to the part of the planned path in the display area according to the part of the planned path in the display area, so that the driving intention of the vehicle can be accurately transmitted to the user, the sense of distrust of the user on the intelligent driving function can be effectively reduced, and the frequency of unnecessary taking over of the vehicle by the user can be reduced. In some possible implementations, the portion of the planned path in the display area may include a first segment of path on a first grade road surface and a second segment of path on a second grade road surface, where the first segment of path is connected to the second segment of path. Displaying the navigation element in the display area that is in contact with the portion of the planned path may include in the display area, contacting a first portion of the navigation element with the first segment of the path and contacting a second portion of the navigation element with the second segment of the path. In a real scenario, there may be undulations in the road on which the vehicle is located. If the vehicle speed is too fast on the undulating road, the vehicle will jump from the ground, and part or all of the wheels will come into contact with the ground again after being emptied for a period of time, on the one hand, the wheel emptying will cause the increase of instability of the vehicle, on the other hand, the vehicle will be impacted when falling to the ground, and even the chassis and other parts will be damaged when serious. In the application, under the condition that the part of the planned path in the display area comprises a plurality
