Elevated road recognition method, device, computer equipment and storage medium

Abstract

The present application relates to an elevated-based road identification method, device, computer equipment and storage medium. The method includes: performing positioning according to the first wireless signal information in the positioning request to obtain an initial positioning position; screening candidate geographic grids corresponding to a positioning area including the initial positioning position from a navigation fingerprint library; obtaining each candidate geographic grid The second wireless signal information, the second wireless signal information is collected at the location key point corresponding to the candidate geographic grid; based on the matching of the second wireless signal information corresponding to each candidate geographic grid and the first wireless signal information The wireless signal matching feature screens out the target geographic grids that meet the matching conditions from the candidate geographic grids; according to the elevated attribute information corresponding to each target geographic grid, the road identification result of the road where the originator of the positioning request is located is determined. The method can accurately identify the road on which the user is located as the road on the upper side of the elevated road or the road on the lower side of the elevated road, and can be used for map navigation.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an elevated-based road identification method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, the functions of electronic maps are becoming more and more comprehensive. People can use electronic maps to find destinations, plan walking routes, plan vehicle routes, and real-time navigation. However, route planning and navigation need to locate the current position. If the current position is not accurately located, the planned route will not be accurate. [0003] In the existing electronic map data, there are very few road data on the viaduct and the road under the bridge in the electronic map. When the route planning and navigation involve the road on the viaduct or the road under the bridge, the positioning of the current position is very difficult. Not exactly.
