Black and odorous water positioning method and device based on remote sensing image and related equipment

Abstract

The invention relates to the technical field of pollutant tracing, and provides a black and odorous water positioning method and device based on a remote sensing image and related equipment thereof. The method comprises the following steps: obtaining a target remote sensing image from an original remote sensing image; obtaining the reflectivity of an object in the target remote sensing image, andobtaining the normalization index of the object corresponding to each color through the reflectivity calculation; when the normalization index is within a preset first monitoring threshold range, determining the object corresponding to the normalization index as a target water body; acquiring spectral reflectance of a target water body in red, green and blue bands in the target remote sensing image; calculating according to the spectral reflectance to obtain black and odorous water body indexes; when the black and odorous water body index is within a preset second monitoring threshold range, determining a target water body in a range corresponding to the black and odorous water body index as a black and odorous water body. According to the embodiment of the invention, the method can solveproblems in the prior art that the positioning of the black and odorous water is lower in precision and is larger in calculation amount.

Description

technical field [0001] The invention relates to the technical field of traceability of pollutants, in particular to a method, device and related equipment for locating black and odorous water bodies based on remote sensing images. Background technique [0002] In recent years, as people's awareness of environmental protection has gradually increased, water pollution has become a key issue of concern, and effective reduction of black and odorous water discharge has become a key task of government departments. In order to ensure that the discharge of black and odorous water does not exceed the standard, it is necessary to quickly locate the pollution source that exceeds the standard, otherwise a good restraint mechanism cannot be formed. At present, there are generally two methods for locating black and odorous water. The first method is to densely deploy black and odorous water monitoring stations at various water body points to monitor black and odorous water. The second met...
