多旋翼无人机在尾矿坝坝体变形监测中的应用研究

Application of multi rotor UAV in dam deformation monitoring

传统的尾矿坝坝体变形监测一般采用的固定翼无人机,在坝体变形这种不确定、非线性系统上的控制效果不理想导致监测存在误差,因此对多旋翼无人机在尾矿坝坝体变形监测中的应用进行研究。首先对多旋翼无人机中的图像采集模块进行设计,对摄像头的参数、云台的型号和图像处理器的参数进行了选择,通过对图像采集模块监测得到的数据进行分析,完成数据建模,以此为基础进行坝体的变形监测。以实际的尾矿坝坝体作为测区,对两种监测方法进行测试,实验结果表明,设计的多旋翼无人机监测方法具有更准确的监测结果。

The fixed wing UAV is usually used in the deformation monitoring of tailings dam.The control effect on the uncertain and nonlinear system of dam deformation is not ideal,which leads to the monitoring error.Therefore,the application of multi rotor UAV in the deformation monitoring of tailings dam is studied.Firstly,the image acquisition module of multi rotor UAV is designed,and the parameters of camera,pan tilt and image processor are selected.By analyzing the data monitored by the image acquisition module,the data modeling is completed,and the dam deformation monitoring is carried out on this basis.The two monitoring methods are tested from the actual tailings dam as the test area.The experimental results show that the designed multi rotor UAV monitoring method has more accurate monitoring results.
