Embodiment 1

[0029] Such as figure 1 As shown, the embodiment of the present invention provides a high-precision electronic map navigation method, including the following steps:

[0030] 101. Acquire lane information; the lane information includes at least one of the following information: lane position, lane length, lane width, lane shape, lane line shape, lane line position, lane line attributes (such as dashed lines, solid lines, double yellow lines, etc.) , lane direction, lane attributes (such as bus lanes, truck lanes, lane restriction information, etc.), or lane conditions (such as congestion, slowing, smooth, etc.).

[0031] Lane position, lane length, lane width, lane shape, lane line shape, lane line position, lane line attributes (such as dashed lines, solid lines, double yellow lines, etc.), lane direction, lane attributes (such as bus lanes, truck lanes, Lane restriction information, etc.) can be collected on the spot by using laser point cloud technology, and the road cond...

Embodiment 2

[0037] The embodiment of the present invention also provides a high-precision electronic map navigation device, including:

[0038] The input unit 201 is configured to receive an operation instruction from a user.

[0039] The information calling unit 202 is used to call lane information and vehicle parameters. The vehicle parameters are input by the user through the input unit 201 and stored in the navigation device or a server communicated with the navigation device, and the vehicle parameters include at least one of the following information: vehicle length, vehicle height, vehicle weight or vehicle type (such as cars, trucks, buses, etc.). The lane information is pre-stored in the navigation device or a server connected to the navigation device by a high-precision electronic map service provider, and the lane information includes at least one of the following information: lane position, lane length, lane width , lane shape, lane line shape, lane line position, lane line ...

Abstract

The present invention discloses a high-precision electronic map navigation method and a high-precision electronic map navigation device, and related to the field of high-precision electronic maps. Thehigh-precision electronic map navigation method comprises: determining a departure place and a destination; performing path planning according to the departure place, the destination, and pre-acquired vehicle parameters and lane information, and acquiring a lane level navigation path; and performing lane level navigation according to the navigation path. The method provides a user with lane-levelhigh-precision navigation by performing the path planning based on the lane information and the vehicle parameters.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to high-precision electronic maps. Background technique [0002] Electronic map (English: Electronic map), that is, digital map, is a map that is stored and consulted digitally using computer technology. Electronic map data generally includes roads, points of interest, and road networks. Electronic map is a system of map making and application. It is a map generated by electronic computer control. It is a screen map based on digital cartography technology and a visualized real map. "Visualization on the computer screen" is the fundamental feature of electronic maps. [0003] The characteristics of the electronic map are as follows: [0004] 1. The display can be quickly accessed. [0005] 2. Animation can be realized. [0006] 3. Map elements can be displayed in layers. [0007] 4. Using virtual reality technology to make the map three-dimensional and dynamic, so that users have...
