基于无人机多光谱遥感图像信息的水质污染监测研究

Study on Water Pollution Monitoring Based on UAV Multi-spectral Remote Sensing Image Information

近几年国家对生态环境越来越重视,以生态为主题的课题不断被广泛提出,其中水资源污染监测是其中的核心环节。以往的河湖等水资源监测需要消耗大量的人力、物力和时间。随着无人机、遥感技术和成像光谱仪的发展,以及机器学习相关领域的快速发展,一种以无人机搭载多光谱成像仪的新型技术被广泛应用。以项目为实例,采用无人机搭载多光谱传感器对水质进行成像,通过专业技术手段,对影像进行水质分析,通过和实际水质采样数据对比,分析该技术手段的可行性和准确性。

In recent years,China has paid more and more attention to the ecological environment,and the subject of ecology has been put forward widely,among which the monitoring of water pollution is the core.In the past,river and lake water resources monitoring needs to consume a lot of manpower,material resources and time.With the development of Unmanned Aerial Vehicle(UAV),Remote Sensing Technology and Imaging Spectrometer,as well as the rapid development of machine learning related fields,a new kind of technology with multi-spectral imager on UAV has been widely used.Taking the project as an example,the UAV carrying multi-spectral sensor is used to image the water quality.The water quality of image is analyzed by professional technical means.The feasibility and accuracy of the technique are analyzed by comparing with the actual water quality sampling data.
