Multi Objective Abnormal State Monitoring Method for Unmanned Aerial Vehicle Inspection of Transmission Lines
输电线路往往跨越多种地形和气候条件,针对无人机采集的巡检图像质量提出了更高要求.为此,研究输电线路无人机巡检多目标异常状态监测方法.首先,在相机平面上建立视觉的二维坐标系,校正输电线路无人机巡检视觉.其次,针对输电线路的异常状态,根据电力线的初始应力,计算异常状态点的最大曲率,实现位置估算.最后,计算导线由于荷载引起的偏心量,得到输电线路的多目标异常状态.试验结果表明,所提方法拟合优度指标始终高于95%,在 600 次的迭代试验中,其误检率变化不大,最高为 0.26%,说明研究提出方法具有非常明显的应用优势.
Transmission lines often span multiple terrains and climatic conditions,which poses higher requirements for the quality of inspection images collected by drones.To this end,it studies a multi objective abnormal state monitoring method for unmanned aerial vehicle inspection of transmission lines.Firstly,it establishes a visual two-dimensional coordinate system on the camera plane to cali-brate the visual inspection of unmanned aerial vehicles inspection for transmission lines.Sceondly,based on the abnormal state of the transmission line,it calculates the maximum curvature of the abnormal state point for transmission line,achieving position estimation.Finally,it calculates the eccentricity of the conductor caused by the load to obtain the multi objective abnormal state of the transmission line.The experimental results show that the goodness of fit index of the research method is always above 95%.In the 600 iterations of the experiment,the false detection rate does not change much,with the highest being 0.26%,indicating that the proposed method has application advantages.
