Problems solved by technology

[0005] (1) Time-consuming and labor-intensive, high cost
[0006] (2) The reusability of data is very low. If you regenerate 2.5D maps with different resolutions and different azimuths, the address data must be recreated once

Abstract

The invention discloses a map address matching method, a device, terminal equipment and a storage medium, comprising: according to a set 2.5D map range and 2.5D map parameters, extracting a pluralityof 2.5D maps from a 3D map; among them, 2.5D map records the center point, the origin parameter, the actual coordinate and the camera parameter; according to the drawing center point, drawing origin parameter, actual coordinate and camera parameter, all 2.5D maps are stitched together to get 2.5D maps of the target; according to the origin parameters and camera parameters, the coordinates of the address data are matched to the actual position of the scene of the target 2.5D map; and outputting new address data that matches the target 2.5D map. The embodiment of the invention can quickly, efficiently and accurately match the coordinates of the address data to the actual position of the scene of the target 2.5D map by converting the plane coordinates of the rectangular coordinates by using the map parameters and the camera parameters.

Description

technical field [0001] The present invention relates to the technical field of geographical information data processing, in particular to a map address matching method, device, terminal equipment and storage medium. Background technique [0002] Address matching is the process of establishing a correspondence between a literal description address and its geographic location coordinates. The address matching service follows specific steps to find a match for an address. Addresses are first standardized; then the server searches address-matching reference data for potential locations; assigns a score to each candidate location based on its proximity to the address, and finally uses the one with the highest score to match the address. [0003] In the prior art, a 2.5D map is generated through a three-dimensional map, and the generated map does not have real coordinates, so the existing address data cannot be configured with the location of the 2.5D map. On the basis of second...
