Problems solved by technology

[0004] However, the existing visualization schemes all have the following defects: 1) manual modeling, the production cost is too high, and professionals are required to produce data; 2) automatic photography 3D modeling requires data collection, and the amount of collected data is particularly large and noisy. 3) The existing map display scheme, due to the simple and extensive display effect of road data and road navigation, makes the user's yaw rate higher

Embodiment 1

[0039] Figure 1A It is a flow chart of a navigation vector data visualization method provided by Embodiment 1 of the present invention. This embodiment is based on the road data collected in the existing map visualization, which only includes road descriptive data such as road centerlines and road connection point models. There is no data about how the road is displayed, and the existing display schemes cannot induce users well in terms of aesthetics and refinement. The method can be executed by the navigation vector data visualization device / server / computer-readable storage medium provided by the embodiment of the present invention, and the device / server / computer-readable storage medium can be implemented by software and / or hardware. see Figure 1A , the method specifically includes:

[0040] S110. Determine the width of each road included in the current map data according to the number of lanes in the current map data.

[0041] Among them, the current map data refers to al...

Embodiment 2

[0057] Figure 2A It is a flow chart of a navigation vector data visualization method provided in Embodiment 2 of the present invention, Figure 2B It is a schematic diagram of a visualization process of navigation arrows in navigation vector data provided by Embodiment 2 of the present invention. The navigation vector data visualization method is based on the first embodiment of the present invention, further optimizes the data after the visualization result of the current map data is generated according to the boundary clipping result, and provides a navigation arrow visualization method. Specifically, see Figure 2A The method can include:

[0058] S210. Determine the width of each road included in the current map data according to the number of lanes in the current map data.

[0059] S220, according to the width of each road contained in the current map data, determine the boundary line of each road and the intersection point of the boundary line.

[0060] S230. Perfor...

Embodiment 3

[0072] Figure 3A It is a flowchart of a navigation vector data visualization method provided by Embodiment 3 of the present invention. The navigation vector data visualization method is based on Embodiment 1 of the present invention, and further determines the number of lanes in the current map data based on the number of lanes in the current map data. The width of each road included is explained. Specifically, see Figure 3A The method can include:

[0073] S310. Determine the width of each road included in the current map data according to the number of lanes in the current map data, the width of the maximum number of lanes, the width of a single lane, and the maximum number of lanes.

[0074] Among them, a road is composed of multiple lanes, and the width of each lane is the width of a single lane; the width of the maximum number of lanes refers to the width of the widest road among all roads in the scene; correspondingly, the maximum number of lanes refers to the width ...

Abstract

The embodiment of the invention discloses a visualization method, device, equipment and storage medium of navigation vector data. Wherein, the method includes: determining the width of each road included in the current map data according to the number of lanes in the current map data; determining the boundary line of each road and the width of each road included in the current map data according to the width of each road The intersection point of the boundary line; performing boundary clipping according to the intersection point of the boundary line, and generating the visualization result of the current map data according to the boundary clipping result. The technical solution provided by the embodiment of the present invention provides a more accurate way to determine the width of the road, and fills the gap in the graphic data of the bifurcation when making decisions during navigation, further reduces the yaw rate of the user, and improves the navigation efficiency. Induction.

Description

technical field [0001] The present invention relates to the technical field of map navigation, in particular to a visualization method, device, equipment and storage medium of navigation vector data. Background technique [0002] In the information age, with the development of Internet technology, maps have become one of the most important references for people to make decisions before travel, and the visualization of roads in maps brings convenience to users' travel. [0003] At present, road visualization schemes mainly fall into the following three categories: 1) Manual modeling, generally, 3DSMAX can be used to realize real scene zoom-in based on actual scene modeling; or several specific turning models can be used to realize mode zoom-in; 2) Automated photography 3D modeling , the method is to use drones to collect real scene data first, and then convert the collected data into a 3D model for display; 3) The existing map display scheme mainly sets the width according to...
