Method, device and electronic equipment for area adjustment of electronic map

Abstract

This specification discloses an electronic map area adjustment method, device, and electronic equipment. The method includes: obtaining an area to be adjusted in the electronic map; processing to obtain a pre-processed polygon; the preset pre-processing rule is used to remove the abnormal area in the polygon corresponding to the area to be adjusted; based on the preset adjustment direction and the preset adjustment distance, the A plurality of edges in the preprocessed polygon are equidistantly adjusted to obtain an adjusted polygon, wherein the isometric adjustment includes one of expansion adjustment and scaling adjustment; based on the adjusted polygon and The corresponding relationship of the area to be adjusted on the geographical location, updating the position and range of the area to be adjusted in the electronic map.

Description

technical field [0001] This document relates to the field of computer technology, in particular to an area adjustment method, device and electronic equipment for an electronic map. Background technique [0002] At present, when conducting business development for offline merchants, areas with more traffic are often preferred as target areas for business development. The electronic fences corresponding to these target areas can be excavated by machine learning to form corresponding polygonal areas, wherein a polygonal area contains multiple GPS coordinate points, and one GPS coordinate point corresponds to a user's location. [0003] However, in the above scenario, if the user's GPS coordinate point drifts due to factors such as building occlusion, bad weather, etc., the user's GPS coordinate point will be inaccurate. In this case, the actual geographical location of one or more users corresponding to the GPS coordinate points contained in a certain polygonal area may not be...

[0003] However, in the above scenario, if the user's GPS coordinates drift due to building occlusion, bad weather, etc., the user's GPS coordinates will be inaccurate

In this case, the actual geographical location of one or more users corresponding to the GPS coordinate points contained in a certain polygonal area may not be in the polygonal area, which will lead to a relatively low coverage rate of the electronic map area mined. Low
