Abstract

The present application discloses a method, device and storage medium for obtaining topological relationship based on spatial position, wherein the method includes: obtaining the WGS84 historical coordinate point data of the target object, and using the WGS84 historical coordinate point data to generate The real geographic projection coordinate plane of the target object; obtain the WGS84 real-time coordinate point data of the target object, and project the WGS84 real-time coordinate point data to the Web Mercator coordinate system to obtain the geographic projection coordinates of the target object; the geographic projection coordinates of the target object and the real The topological calculation is carried out on the geographic projection coordinate plane to obtain the topological relationship. This method effectively improves the accuracy of topological relationship calculation, can give full play to the value of historical scattered point data, and is beneficial to monitor the accuracy of decision makers in making decision plans.

Description

technical field

[0001] The present application relates to the technical field of spatial position monitoring systems, and in particular to a method, device and computer-readable storage medium for acquiring a topological relationship based on spatial position. Background technique

[0002] At present, the real-time monitoring system or related platforms and their services derived from spatial locations will become more and more important with the development of the Internet of Things (the blowout of the number of Internet of Things devices and the enhancement of the ability of each device to collect spatial locations), and it is very likely that Become an indispensable part of the application, and the spatial calculation based on the positioning position will undoubtedly inject the soul of the spatial level into the application.

[0003] In related technologies, the business system for spatial position monitoring generally adopts calculations based on two-dimensional plane p...

Embodiment Construction

[0044] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0045] At present, the business system for spatial position monitoring is stuck on the user’s step-by-step operation at the business level. For example, setting up electronic fences and canceling electronic fences is too cumbersome and rigid, and cannot effectively use the monitoring objects themselves to dig out their own historical positioning.
