Map area determination method and device, equipment and storage medium

Abstract

The invention relates to the field of image processing, and particularly discloses a map area determination method, device and equipment and a storage medium. The method includes: acquiring a regionalimage; caryring out image recognition on the regional image to obtain a contour line used for representing the regional image, and the contour line comprises a plurality of pixel points; preprocessing the plurality of pixel points according to the pixel point coordinates of the pixel points on the regional image to obtain a pixel point coordinate set; performing coordinate conversion on pixel point coordinates in the pixel point coordinate set based on a mapping relationship between the regional image and a map to obtain a longitude and latitude coordinate set corresponding to the pixel pointcoordinate set; and drawing a target area corresponding to the contour line on the map according to the longitude and latitude coordinate set. And the accuracy of obtaining the longitude and latitudecoordinates of the irregular area is improved.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method, device, equipment and storage medium for determining a map area. Background technique [0002] Currently, there are usually two methods for obtaining the latitude and longitude coordinates of some irregular areas. When there are specific latitude and longitude coordinates, you can use some software to draw on the map. By obtaining the vertex coordinates or circumference coordinates, and recording the order of the drawing points when drawing points, you can use the recorded order of drawing points to connect the vertices in turn. Vertex coordinates and drawing order redraw these irregular areas. However, this method must be drawn in real time, and the accuracy of drawing cannot be guaranteed when drawing multiple times. When there is no specific latitude and longitude coordinates, it is necessary to manually draw points on the map according to the shape of...

However, this method must be drawn in real time, and the accuracy of the drawing cannot be guaranteed when drawing multiple times

When there are no specific latitude and longitude coordinates, it is necessary to manually draw points on the map according to the shape of these irregular areas, but this drawing method not only takes a lot of time, but also has low accuracy
