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...
