High-precision map drawing method based on Internet of Vehicles

Abstract

The invention discloses a high-precision map drawing method based on the Internet of Vehicles, and belongs to the technical field of map drawing, and the method specifically comprises the steps that an Internet of Vehicles client and a remote platform end are arranged, the Internet of Vehicles client is used for collecting vehicle environment information, and the remote platform end is used for processing the information collected by the Internet of Vehicles client; identifying data types collected by the Internet of Vehicles clients, marking priorities corresponding to the collected data types, establishing a plurality of 5G transmission channels between the Internet of Vehicles clients and the remote platform end based on a 5G slicing technology, and marking priorities for the established 5G transmission channels; the map is subjected to three-dimensional processing, so that a user can identify the direction more conveniently, and navigation errors are avoided; the 5G slicing technology is fully utilized, the transmission efficiency of the collected data is improved, three building states are preset when the building model is established, subsequent state replacement is facilitated, and the method is more convenient, visual and symbolic.

Description

technical field [0001] The invention belongs to the technical field of map drawing, in particular to a high-precision map drawing method based on the Internet of Vehicles. Background technique [0002] As an integral part of unmanned intelligent driving technology, high-precision maps have been widely used in the field of automotive intelligent driving, providing possibility and feasibility for intelligent driving functions. Both traditional map data providers and Internet companies that provide map services can visualize map data to a certain extent. However, most of the maps they involve are displayed on two-dimensional maps; the map instructions are poor, and users are prone to misreading the map signs; especially for pedestrian users, because of direction problems and marker problems, they often go the wrong way The phenomenon occurs; some enterprises have also begun to explore the use of the Internet of Vehicles for map drawing, but the existing way of using the Intern...
