A rapid detection method for water pollution based on drone

Abstract

The invention discloses a method for rapid detection of water body pollution based on unmanned aerial vehicles, including S1, planning the flight trajectories of two unmanned aerial vehicles, and selecting the type of pollutant detection test paper; S2, selecting an unmanned aerial vehicle to carry the detection test paper along Predetermined trajectory flying and sowing test paper, another UAV takes pictures of the target waters along the predetermined trajectory, and obtains remote sensing images of the target waters; S3, combining the UAV and GPS positioning system to obtain the precise coordinates of each UAV remote sensing image ; S4, using the coordinate values ​​for fast image stitching to obtain the image of the target area; S5, extracting the test paper area in the image of the target area, and comparing it with the standard color comparison card, to obtain the properties of the water solution in the target area to be detected; S6, obtaining the detection The value of the color card in the test paper area is used to determine the pollutant concentration value of the specific pollutant solution in the target area corresponding to the coordinate point, and the pollutant concentration map of the entire target area is obtained using the linear interpolation method.

Description

technical field [0001] The invention belongs to the technical field of water pollution detection, and in particular relates to a rapid detection method for water pollution based on an unmanned aerial vehicle. Background technique [0002] Water is the foundation of all life on earth and the origin of life. In human life, food, clothing, housing, transportation, industrial production, agricultural production, inland river and ocean transportation are also based on water. However, with the rapid development of my country's urban economy and the continuous advancement of industrialization, a large amount of untreated domestic sewage and industrial wastewater are discharged into rivers. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. In view of this, how to protect water resources a...
