Embodiment 1

[0028] figure 1 It is a flow chart of a method for drawing a guiding arrow provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the user is assisted in navigation based on the display of the guidance area. Typically, this embodiment is applicable to the situation where the AR navigation is performed for the user based on the guidance area. The method can be performed by a guiding arrow drawing device. The device can be realized by software and / or hardware. see figure 1 , the guiding arrow drawing method provided in this embodiment includes:

[0029] S110. Determine the current guidance area of ​​the vehicle during map navigation.

[0030] Wherein, the current guidance area is the area of ​​the guidance line at the current moment.

[0031] The guide line here is a line that guides the user in the driving direction according to the navigation route. The line has a certain width, which can be set as required. Typically, t...

Embodiment 2

[0067] Figure 2a It is a flow chart of the guiding arrow drawing method provided by Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see Figure 2a , the guiding arrow drawing method provided in this embodiment includes:

[0068] S210. Determine the current guidance area of ​​the vehicle during map navigation.

[0069] S220. Determine the position of the guiding arrow in the current guiding area according to the position of the guiding arrow in the historical guiding area and the moving distance of the guiding arrow.

[0070] S230. Determine the direction and size of the guiding arrow respectively according to the curvature and width at the location of the guiding arrow in the current guiding area.

[0071] Specifically, according to the curvature at the location of the guiding arrow in the current guiding area, determine the direction of the guiding arrow;

[0072] Determines the size of t...

Embodiment 3

[0082] image 3 It is a flow chart of a method for drawing a guiding arrow provided in Embodiment 3 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see image 3 , the guiding arrow drawing methods provided in this example include:

[0083] S310. Based on the identified lane line or the route of the high-precision map, determine a guidance area ahead of the current vehicle.

[0084] S320. Draw a dynamically moving forward guiding arrow based on the guiding area.

[0085] Among them, the effect of guiding arrow flow is determined according to the starting position of drawing the guiding arrow moving forward and the interval between the arrows.

[0086] The starting position of the guide arrow drawing changes with the advancement of the previous state. For the current guidance area, the starting position of the guidance arrow drawing is the position of the guidance arrow in the guidance area at the previou...

Abstract

The embodiment of the invention discloses a guiding arrow drawing method, device, equipment and medium, which relate to the technical field of intelligent transportation. The method comprises steps: acurrent guiding area of a vehicle during a map navigation process is determined; the position of the guiding arrow in the current guiding area is determined according to the position of the guiding arrow in a historical guiding area and the moving distance of the guiding arrow; and according to the position of the guiding arrow in the current guiding area, the guiding arrow is drawn in the current guiding area, and the guiding arrow is moved to the current guiding area from the historical guiding area. According to the guiding arrow drawing method, the device, the equipment and the medium provided by the embodiment of the invention, a visual effect of enhancing a direction guiding line is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a method, device, equipment and medium for drawing a guiding arrow. Background technique [0002] Vehicle assisted driving technology is also called advanced driving assistance system (Advanced Driving Assistant System, referred to as ADAS). Vehicle assisted driving includes many functions, including an augmented reality (Augmented Reality, AR) navigation function based on directional guidance lines. The direction guide line is a guide line used to indicate the driving direction of the vehicle. [0003] AR navigation is a navigation mode that combines real scenes to provide users with augmented reality, and the user's visual experience is very important. [0004] In AR navigation products, direction guidance lines are usually displayed in static forms such as lane line interval coverage or fixed-width area coverage. However, the...
