Abstract

The invention discloses a ground mark determination method which comprises the steps of acquiring a point cloud grey chart, running a mark extraction network model to acquire ground mark information from a road section map, and determining a target ground mark in ground marks according to the ground mark information, wherein the point cloud grey chart comprises a road section map; the mark extraction network model used for extracting the ground marks contained in the road section map; the ground mark information comprises information of each ground mark extracted by the mark extraction model;and the ground marks are driving indication information marked on ground of a road section. According to the method, the ground mark information in the road section map is acquired by the mark extraction network model; and the ground marks in the road section map are determined according to the ground mark information, so that the efficiency and accuracy of the ground marks in the road section mapare improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method for extracting ground signs, a method for model training, a device, and a computer-readable storage medium. Background technique [0002] High-precision maps are the core content of autonomous driving, which provide rich and accurate road information for autonomous driving. Ground markings are the core elements of high-precision maps. Ground markings include arrows, text, and graphics. Ground markings can assist cars in precise positioning, and then help cars make appropriate plans and decisions. [0003] At present, the extraction of ground signs in high-precision maps mainly relies on manual editing. Specifically, in the editing tools of high-precision maps, by manually viewing point cloud data or point cloud grayscale data, find out the areas containing ground signs, and then Manually draw the rectangular bounding box of each ground mark, and edit the...
