无人机遥感技术在水土保持监测中的应用

Application of UAV Remote Sensing Technology in Soil and Water Conservation Monitoring

随着国家经济的飞速发展,传统方式已难以满足日益严格的水土保持监管要求。以惠民段河道治理工程为例,引入无人机垂直摄影和倾斜摄影测量技术,对项目区的两个地块和一处堆土区进行拍摄,利用Agisoftmetashape Professional、Context Capture Master等软件生成项目区正射影像以及三维模型。结果表明,利用无人机遥感技术可获取项目区扰动土地面积及堆土土方量等数据,并且监测精度符合水土保持监测要求,在水土保持监测中无人机遥感技术发挥了重要作用,为水土保持监管提供重要技术支撑。

With the rapid development of national economy,it is difficult for traditional methods to meet the increasingly strict supervision requirements of soil and water conservation.Taking the Huimin Section river channel regulation project as an example,UAV vertical photography and tilt photography technology were introduced to photograph two plots and a soil pile area in the project area.Agisoftmetashape Professional,Context Capture Master and other software were used to generate orthophoto images and 3D models of the project area.The results show that UAV remote sensing technology can be used to obtain the data of disturbed land area and pile soil volume in the project area,and the monitoring accuracy meets the requirements of soil and water conservation monitoring.Unmanned aerial vehicle remote sensing technology plays an important role in soil and water conservation monitoring,providing important technical support for soil and water conservation supervision.
