Black and odorous water body remote sensing recognition system and method

Abstract

The black and odorous water body remote sensing recognition system comprises a communication network formed by a main control device and a plurality of monitoring devices, the plurality of monitoring devices are respectively arranged at points to be recognized and are used for collecting dissolved oxygen, ammonia nitrogen values, transparency and chromaticity of a water area according to a preset period, calculating a normalized index of the water area and storing the normalized index; the main control device is used for sending a broadcast instruction, judging the normalization index returned by the monitoring device, determining the corresponding water area water body as a target water body when the normalization index is within a first preset range, and sending a black and odorous water body recognition demand; the remote sensing image collection module is used for collecting a remote sensing image of the target water body from the original remote sensing image; and the black and odorous water body confirmation module is used for calculating a black and odorous water body index of the target water body according to the remote sensing reflectivity of the target water body in each wave band, and when the black and odorous water body index is within a second preset range, determining that the target water body is the black and odorous water body.

Description

technical field [0001] The invention relates to the technical field of identification of black and odorous water bodies, in particular to a system and method for remote sensing identification of black and odorous water bodies. Background technique [0002] "Black odor" is an extreme phenomenon of organic pollution in water bodies, which is caused by the lack of oxygen in water bodies and the corruption of organic matter. At present, domestic and foreign research on black and odorous water bodies mostly focuses on the formation mechanism of black and odorous water, water quality evaluation methods and index construction, ecological restoration, etc., but the research on its identification method is still very lacking. [0003] The identification of black and odorous water bodies in my country is mainly judged through on-the-spot investigations, and the judgment of black and odorous water bodies is carried out by combining the subjective feelings of the human body with the mea...

Problems solved by technology

This patent application is also aimed at the identification of black and odorous water bodies based on remote sensing data of all identification points, without first distinguishing the water bodies before identification, resulting in an excessive amount of data for identification and low identification efficiency
