Unmanned aerial vehicle imaging spectrum-based medium and small water body water quality type identification method

Abstract

The invention relates to an unmanned aerial vehicle imaging spectrum-based medium and small water body water quality type identification method. The method comprises the following steps: (1) acquiringa water body water quality type and a water body spectral reflectivity curve; (2) establishing a water quality type identification model; (3) acquiring a target water body spectral image; (4) processing an unmanned aerial vehicle imaging spectral image; (5) extracting a spectral reflectivity of the unmanned aerial vehicle imaging spectral image; and (6) identifying water quality types of medium and small water bodies, and the like. The method realizes automatic identification of water quality of medium and small water bodies, has the advantages of high identification speed and high identification accuracy, can be used as a beneficial supplement of a traditional water quality monitoring means, and improves the service level of water quality monitoring of the medium and small water bodies.

Description

technical field [0001] The invention relates to the field of reflection spectrum and image processing, in particular to a method for identifying water quality types of small and medium water bodies based on UAV imaging spectrum. Background technique [0002] The water environment is closely related to everyone. Water bodies have multiple functions such as drinking water sources, agricultural irrigation, industrial and agricultural production, landscape, and shipping. With the improvement of people's living standards, the requirements for the ecological environment, especially the quality of the water environment, are gradually increasing. The country has formulated the planning goal of basically eliminating inferior V water bodies by 2020. The Yangtze River Delta region is densely covered with rivers and lakes, and individual rivers and lakes are small-scale water bodies. How to quickly and economically obtain the water quality types of these small and medium-sized water bod...

AI Technical Summary

Problems solved by technology

The rivers in the Yangtze River Delta region are intricate, with many rivers and lakes, wide distribution, and relatively small scale. Traditional monitoring methods are time-consuming and laborious to sample and monitor so many rivers and lakes. The existing satellite remote sensing technology is limited by meteorological conditions and spatial resolution. Due to the limitation of spectral resolution, it is difficult to quickly monitor the water quality of small and medium water bodies. Therefore, a new type of remote sensing technology is urgently needed to automatically identify the water quality category of small and medium rivers, which can be applied to the water quality monitoring of small and medium rivers.
