specific Embodiment approach

[0062] Optionally, the embodiment of this specification provides a specific implementation manner of deleting connected domains whose area is smaller than a preset threshold, as follows:

[0063] judging whether the area of ​​the connected domain is smaller than a preset threshold, and obtaining a first judging result;

[0064] When the first determination result indicates that the area of ​​the connected domain is smaller than the preset threshold, all the pixels in the connected domain are filled with 0.

[0065] In the embodiment of this specification, deleting the connected domain whose area is smaller than the preset threshold is to assign the pixel in the connected domain to the value of the pixel in the background area, that is, modify it from 1 to 0. That is, the connected domain is treated as the background area.

[0066] In the embodiment of this specification, the preset threshold can be set according to the actual situation, for example, it can be set according to...

Abstract

The embodiment of the invention discloses a geofence data extraction method, a device and equipment. The method comprises the steps of acquiring a target geofence image, wherein the target geofence image comprises reference points with known geographic coordinates; preprocessing the target geo-fence image to obtain a binarized image with a closed contour; converting the binarized image into an ordered point sequence set; and determining the geographic coordinates of each pixel point of the point sequence set according to the geographic coordinates of the reference points.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and equipment for extracting geofence data. Background technique [0002] Geoserver can publish map services on the Internet, and has format requirements for data. Due to the difficulty in obtaining basic data, map services are often prone to missing local geofence data. For example, the boundaries of large areas often exist, but for some commercial districts, due to the irregular terrain, the boundary data is often not easy to obtain, and the lack of these data will affect people's judgment based on the map data the accuracy. Contents of the invention [0003] In view of this, the embodiments of the present application provide a method, device and equipment for extracting geofence data, so as to solve the problem of missing data in map services. [0004] In order to solve the above-mentioned technical problems, the embodiments of this specificat...
