Method and device for identifying ammonia nitrogen, storage medium and apparatus

Abstract

The invention relates to a method and a device for identifying ammonia nitrogen, a storage medium and an apparatus. The method comprises the following steps of obtaining an ammonia nitrogen content ata ground black and odorous water body sampling point and the water body reflectivity, in each wave band, of the ground black and odorous water body sampling point; obtaining the water body reflectivity, in each wave band of an unmanned-aerial-vehicle multispectral remote sensing photographic device, of the black and odorous water body sampling point; carrying out correlation analysis on the ammonia nitrogen content at the ground black and odorous water body sampling point and the water body reflectivity, in each wave band of the unmanned-aerial-vehicle multispectral remote sensing photographic device, of the black and odorous water body sampling point, and determining the water body reflectivity of an optimal wave band combination; determining a relational model of the ammonia nitrogen content and the water body reflectivity of the optimal wave band combination; obtaining a black and odorous water body image of a to-be-measured area; and determining the distribution of the ammonia nitrogen according to the relational model and the black and odorous water body image. By using the method, the field measurement of the to-be-measured area is not needed; the chemical assay is also notneeded to be carried out; and the quick identification of the ammonia nitrogen in a black and odorous water body in a large-range area is realized.

Description

technical field [0001] The invention relates to the field of ammonia nitrogen detection, in particular to an ammonia nitrogen identification method, device, storage medium and equipment. Background technique [0002] As the main component of water resources, surface water bodies are also of great significance for their distribution, investigation, governance, planning and monitoring. In the process of urban prosperity, industrial, agricultural and domestic waste water make the surface water in the built-up area of ​​the city no longer clear, and even black and smelly, becoming the black and smelly water in the city. One of the reasons for the formation of these black and odorous water bodies is that the content of ammonia nitrogen in the water is too high. Therefore, the detection of ammonia nitrogen in the black and odorous water bodies has an important guiding role in the distribution and detection of subsequent black and odorous water bodies. [0003] The inventors found...

Problems solved by technology

[0003] The inventors found in the invention and creation of the present invention that the detection of ammonia nitrogen in black and odorous water bodies is usually to directly obtain samples of black and odorous water bodies from the area to be tested on the ground, and directly obtain ammonia nitrogen through chemical detection of samples of black and odorous water bodies This method is limited to the research of small-scale areas, and requires researchers to go to the area to be tested for collection, and chemical detection is required every time to obtain ammonia nitrogen, which is very inconvenient to operate
