Method and device for extracting surface water body information based on remote sensing model

Abstract

The embodiment of the invention discloses a method and a device for extracting surface water body information based on a remote sensing model. The method comprises the following steps: acquiring remote sensing image data; preprocessing the remote sensing image data to obtain processed remote sensing data; setting a corresponding threshold value for the processed remote sensing data; performing binarization processing on the processed remote sensing data according to the threshold value to obtain processed binarization remote sensing data; and extracting the surface water body information according to the processed binarization remote sensing data. Through adoption of the method and the device, the water body information is enhanced gradually; the water body information extraction accuracy and speed are increased; and the problems of incapability of completely restraining background information which is irrelevant to a water body, low extraction accuracy, high time consumption and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for extracting surface water body information based on a remote sensing model. Background technique [0002] Satellite remote sensing technology plays an important role in many fields such as environmental monitoring, resource investigation, disaster prevention and reduction, etc., with many advantages such as real-time, accuracy and macroscopic. The use of remote sensing technology to monitor water quality changes, coastline changes, and natural disasters such as floods has been widely used. The study of water bodies is inseparable from the accurate extraction of water body area, scope, distribution, and boundaries, which is very important for water quality change monitoring, coastline change monitoring, flood monitoring, and post-disaster assessment. [0003] Since the 1970s, water body remote sensing research has been carried out on the four...
