Coastline dynamic monitoring method, monitoring equipment and storage medium

Abstract

The invention provides a coastline dynamic monitoring method, monitoring equipment and a storage medium, and the method comprises the steps: splicing coastline images of a target region, and generating a panoramic image in a preset time sequence; performing geometric registration on the panoramic image by utilizing an orthographic remote sensing image and a plurality of ground control points to obtain a dynamic orthographic image set; and extracting an instantaneous coastline contained in each orthoimage, and calculating and obtaining a monitoring result of the coastline length and the coastline endpoint rate at each moment. According to the monitoring method disclosed by the embodiment of the invention, the computer vision technology and the remote sensing technology are combined to generate the coastline orthoimage, and the real-time monitoring of the length change of the coastline and the end point rate EPR change is realized, so that the requirements of time resolution, space resolution and acquisition of the regional orthoimage are met, and the real-time monitoring of the coastline is realized. Data support is provided for the fields of coastal zone environment monitoring, coastal city development, disaster emergency monitoring and the like.

Description

technical field [0001] The invention relates to the technical field of remote sensing monitoring, in particular to a coastline dynamic monitoring method, monitoring equipment and a storage medium. Background technique [0002] Although the traditional remote sensing observation technology has the advantages of wide observation range and short cycle in coastline dynamic monitoring. However, it is still unable to meet the dynamic monitoring of the coastline of coastal cities, mainly due to the following three limitations. First, in terms of time resolution, the time resolution of image cycles obtained by traditional remote sensing technology observations is generally in units of days, which cannot meet the requirements of coastal cities. Timely observations of ebb and flow tides and storm surges that occur in a short period of time in the offshore; furthermore, in terms of spatial resolution, the resolution of traditional remote sensing images is generally distributed between ...
