Abstract

The invention relates to a road surface identifier generation method and device, a storage medium and electronic equipment, and aims to solve the technical problem of unreasonable road surface identifier generation in related technologies. The method comprises the steps: obtaining the initial position information of a road surface identifier, and extracting the identifier information correspondingto the road surface identifier from an identifier database; determining a vertex of the road surface identifier based on the identifier information, and obtaining an identifier contour of the road surface identifier based on the vertex; carrying out triangulation processing on the identifier contour to obtain a to-be-filled identifier contour; filling the to-be-filled identifier contour to obtaina two-dimensional pavement identifier; and performing three-dimensional conversion on the two-dimensional pavement identifier based on the initial position information to generate the road surface identifier. In this way, the expansibility of road surface identifier generation can be improved, and the rationality of road surface identifier generation can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of map drawing, and in particular, to a method and device for generating road markings, a storage medium, and electronic equipment. Background technique [0002] A high-precision map is a map that completes the reconstruction of the refined driving environment based on the road environment, and is an important technical support for the realization of automatic driving / unmanned driving of vehicles above the L3 level. A high-precision map can be defined in a fine-grained manner, and can perform a large amount of road vector element information (lane line position, type, width, etc.) and fixed object information around the lane (traffic lights, road signs, obstacles, roadside landmarks, etc.) Definition, so as to form a precise definition of the road network. In particular, finely generating road markings can provide accurate vehicle speed configuration and path planning basis for vehicle driving. ...
