High-precision map, high-precision map generation method and use method

Abstract

The invention relates to the field of automatic driving in the field of artificial intelligence, and provides a high-precision map generation method, a high-precision map generated based on the methodand a use method of the high-precision map. According to the method, the high-precision map is split into the general data and the sensitive data in the generation process of the high-precision map,and the general data and the sensitive data have the same map element ID, so that the high-precision map can be subjected to category splitting, and the high-precision map can be stored separately orstored in a unified mode according to the types of the split data. For general data, a use method is obtained according to general map data, for sensitive data, the technical scheme provides single-point object output, a business party can request and obtain the sensitive data of a single-point object according to specific business requirements, and the sensitive data is deleted in time after use,so that the user experience is improved. Therefore, a service party cannot have sensitive data for a long time and cannot have a large amount of sensitive data in the same time period. Through the technical scheme of the invention, the law compliance of using high-precision map data in the field of automatic driving can be solved, so that the popularization of the application of the high-precision map in the field of automatic driving is greatly facilitated.

Description

technical field [0001] The present application relates to the fields of navigation and automatic driving, and in particular, relates to a high-precision map, a method for generating a high-precision map, and a method for using it. Background technique [0002] With the rapid development of 5G communication and Internet of Vehicles technology, autonomous driving technology has become a research hotspot. The core technologies in the field of autonomous driving include intelligent environment perception, automatic navigation and positioning, driving behavior decision-making, and intelligent path planning control. In automatic driving technology, high-precision maps are an important infrastructure and prerequisite for automatic driving. Compared with traditional maps, high-precision maps can reach centimeter-level accuracy and contain multi-dimensional high-precision data, such as road curvature and elevation. , slope, coordinates, height data of bridges and tunnels, etc. High-...
