Abstract

The invention discloses a water quality and health monitoring method based on a remote sensing image. The method comprises the steps of training a BP neural network model by adopting historical monitoring data of a target detection area and the remote sensing image to obtain a water quality parameter inversion model of the target detection area; then applying the water quality parameter inversionmodel to detection of water quality parameters to achieve accurate monitoring of water quality and health. The problem that water quality and health monitoring in the prior art mainly adopts typical section monitoring and aquatic ecological investigation and cannot detect the change of the water quality and health condition of the target detection area for a long time in a full space angle is solved. The invention further provides a water quality and health monitoring device based on the remote sensing image and a storage medium.

Description

technical field [0001] The invention relates to reservoir water quality monitoring and evaluation, in particular to a method, device and storage medium for realizing reservoir water quality health monitoring by using remote sensing technology. Background technique [0002] At present, the water quality monitoring and health assessment of traditional reservoirs are mainly based on typical cross-section monitoring and aquatic ecological investigation, and it is difficult to understand the changing trend of water quality health status in the detection area from a long-term sequence and full space perspective. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology, one of the purposes of the present invention is to provide a water quality health monitoring method based on remote sensing images, which can solve the difficulty in monitoring the water quality health status from a long-term and full-space perspective in the prior art. ...
