Example Embodiment

[0028] Such as figure 1 As shown, the water surface pollutant monitoring and early warning method based on the drone of the present invention includes the following steps:

[0029] (10) Data collection: The drone flies along the set route above the monitored water area, collects millimeter wave radiation data along the way and location information of water surface pollutants, and obtains radiation data;

[0030] In the data collection step (10), a 3mm band radiometer carried by the drone is used to collect millimeter wave radiation data along the way.

[0031] In the data acquisition step (10), the radiation data of the water surface pollutants is obtained by comparing the radiation data along the way with the millimeter wave radiation characteristic data of the typical water surface pollutants established in advance.

[0032] (20) Image acquisition: Based on the radiation data and location information of the pollutants on the water surface, initially determine the key monitoring water...

Abstract

The invention discloses an unmanned aerial vehicle-based monitoring and early warning method and system of water surface pollutants; the method comprises the following steps of data acquisition, image acquisition, feature extraction, type identification and pollution early warning; the monitoring and early warning system comprises an unmanned aerial vehicle monitoring platform (1) used for carrying out general survey, fixed-point detailed survey and real-time monitoring on monitored water areas, and a ground console ( 2 ) used for controlling the working state of the unmanned aerial vehicle monitoring platform (1), determining polluted water areas, extracting image features and generating pollution early warning; the ground console (2) is connected with the unmanned aerial vehicle monitoring platform (1) through remote wireless network signals. The unmanned aerial vehicle-based monitoring and early warning method and system of the water surface pollutants disclosed by the invention carry out whole-day and all-weather operations and are high in monitoring accuracy.

Description

technical field [0001] The invention belongs to the technical field of water surface pollutant monitoring and early warning, in particular to an all-day, all-weather, high-precision monitoring and early warning method for water surface pollutants based on an unmanned aerial vehicle and a monitoring and early warning system for realizing the method. Background technique [0002] In the past ten years, the water surface pollution of lakes has become more and more serious, and major sudden water pollution incidents have occurred frequently, which not only caused immeasurable damage to the ecological environment, but also caused a certain degree of social panic. Once the water surface pollution of the lake occurs, it will be a major regional problem, and the surrounding vegetation, animals, residents and even the entire ecological circle will be affected. Therefore, monitoring and early warning of water surface pollution must be strengthened. [0003] At present, my country has...
