Abstract

The embodiment of the invention discloses a water body pollution detection method, device and equipment and a storage medium. The method comprises the steps of carrying out the atmospheric correctionof original remote sensing image data, and obtaining first remote sensing image data; performing water body correction on the first remote sensing image data to obtain the surface reflectance of the water body in the first remote sensing image data; based on the surface reflectance, establishing a first empirical inversion model of the chlorophyll a and the spectral band of the water body, and a second empirical inversion model of suspended matters and the spectral band of the water body; inputting the second remote sensing image data into the first empirical inversion model and the second empirical inversion model to obtain the concentration of chlorophyll a and the concentration of the suspended matters; and identifying the pollution relationship between the water body and a mining areaaccording to the concentration of chlorophyll a and the concentration of suspended matters. Through two indexes of chlorophyll a and the suspended matter concentration, remote sensing image data are visualized, the pollution relation between the water body and the mining area can be reflected more visually, and a reference basis is provided for monitoring and treatment of water quality.

Description

technical field [0001] Embodiments of the present invention relate to remote sensing technology, and in particular to a water body pollution detection method, device, equipment and storage medium. Background technique [0002] While coal mines bring economic benefits to people, they also pollute the surrounding environment. [0003] Taking water resource pollution as an example, the mining and transportation of coal mines make the concentration of suspended solids in the surrounding surface water higher. Suspended solids are the carriers of various heavy metals and toxic chemicals. These suspended solids will directly enter the light flux in the water body. Pollution to the water body; on the one hand, harmful substances mixed into the water body will cause eutrophication of the water body and endanger the organisms in the water; on the other hand, these harmful substances will enter the human body through the food chain and endanger human health. Therefore, the detection o...
