Problems solved by technology

However, when rendering and displaying in a high-definition map, since the two dotted lines are independent, the solid parts of the two dotted lines cannot be aligned, making the two dotted lines generally unable to achieve the display effect of neatly juxtaposed virtual and real, that is, it does not meet the requirements of road traffic. The style of the marking line is stipulated, so that the driver cannot correctly identify the double dashed line from such a display effect, which in turn affects the normal driving of the driver

Embodiment 1

[0048] figure 1 It is a schematic flowchart of a method for processing dotted lines in a high-precision map shown in an embodiment of the present application.

[0049] see figure 1 , in one embodiment of the present application, a method for processing dotted lines of a high-precision map is provided, which includes:

[0050] Step S110, acquiring the type of the current dotted line to be displayed on the screen.

[0051]In an embodiment, the dotted lines in common road traffic markings can be divided according to the structure, and can include single lines or double lines, where a single line is a single dotted line, and double lines can be double dotted lines and dotted solid lines. Among them, dotted solid lines also include left dotted lines Right solid line or left solid right dashed line and so on. According to the color classification, the dotted lines may also include white dotted lines, yellow dotted lines, or other color dotted lines. The client can obtain the typ...

Embodiment 2

[0058] In order to further introduce the dotted line processing method of the high-precision map of this application, see figure 2 , the dotted line processing method of the high-precision map, including:

[0059] Step S210, according to the position information currently displayed on the screen, acquire the current type of the dotted line to be displayed on the screen.

[0060] In one of the embodiments, the location information currently displayed on the screen is acquired; the location information is sent to the server; wherein, the server pre-stores the data type flag of the dotted line to be displayed corresponding to each location information; the location information sent by the server is received The corresponding data type mark of the dotted line to be displayed. It can be understood that in a high-precision map, different map location areas may contain different road traffic markings. Therefore, the client acquires the location information of the high-precision ma...

Embodiment 3

[0072] Figure 6 It is a schematic structural diagram of a device for processing dotted lines of a high-precision map shown in an embodiment of the present application.

[0073] see Figure 6 , a device for processing dotted lines of high-precision maps according to an embodiment of the present application, which includes a type acquisition module 610 and a dotted line rendering module 620, wherein:

[0074] The type obtaining module 610 is used to obtain the type of the current dotted line to be displayed on the screen.

[0075] The dotted line rendering module 620 is configured to render and obtain the current dotted line to be displayed according to the type of the dotted line to be displayed acquired by the type acquisition module 610 . Among them, according to the preset size, a single square surface is obtained; according to the preset virtual-real ratio and virtual-real configuration file, the corresponding virtual body block and solid block are obtained by rendering ...

Abstract

The invention relates to a dotted line processing method and device for a high-precision map and electronic equipment. The method comprises the steps of obtaining the type of a current to-be-displayed dotted line of a screen; according to the type of the to-be-displayed dotted line, performing rendering to obtain a corresponding to-be-displayed dotted line, wherein a single square drawing is obtained according to a preset size; according to a preset virtual-real proportion and a virtual-real configuration file, performing rendering at a preset position in the single square drawing surface to obtain corresponding virtual body blocks and entity blocks, and forming a single dotted line texture drawing surface; and sequentially splicing the plurality of dotted line texture drawings end to end at a preset position of the screen to form a to-be-displayed dotted line. According to the scheme provided by the invention, the type of the to-be-displayed dotted line is acquired, so that the virtual body block and the entity block which conform to the preset virtual-real proportion and the preset position are acquired in the subsequent rendering in a targeted manner, and then rendering is performed according to the corresponding virtual-real configuration file, thereby ensuring that the road traffic marking line conforming to the standard is acquired.

Description

technical field [0001] The present application relates to the technical field of navigation, and in particular to a method, device and electronic equipment for processing dotted lines of high-precision maps. Background technique [0002] In the high-precision map, the content displayed on the map is more refined, which can bring the driver a more detailed and accurate navigation experience. Among them, for the display of roads, the high-precision map can display specific lane lines and lane dividers on the road surface, and by displaying road traffic markings that match the actual road, the driver can clearly understand the navigation information. [0003] Among them, a single dotted line is generally a line type formed by alternating and alternating colorless virtual body parts and colored solid parts. For two-way roads, between two adjacent opposite lanes, for the position where U-turn can be made, the road surface is generally marked by two parallel dotted lines. Howeve...
