Electronic map road information extraction method and device, equipment and medium

Abstract

The invention discloses an electronic map road information extraction method and device, equipment and a medium, and relates to the field of mapping and mapping in the surveying and mapping and geographic information industry, and the method comprises the steps: employing a progressive registration method, carrying out the registration rectification of a target map slice set, and obtaining a to-be-processed road grid and a to-be-processed annotation grid; extracting a road surface of the target area based on a road surface extraction model; inputting the to-be-processed annotation grids into the annotation information extraction model to obtain single-character discrete characters of the target area; determining an annotation library of the target area; extracting road elements of the target area; and matching the annotation library of the target area with the road elements of the target area, and determining a road entity of the target area according to the name attributes of the road elements of the target area and the road elements of the target area. According to the invention, accurate extraction of electronic map road entities is realized.
