摘　　要：为提高带电作业中输电塔故障检测率,提出基于激光雷达的直升机吊篮法带电作业方法。采用直升机吊篮激光雷达采集输电塔点云数据。利用权重局部优化投影算法去噪。使用D-S理论分类多种特征,计算特征相似性,判别异常点云数据。试验结果表明:基于激光雷达的直升机吊篮法带电作业方法在存在噪声、遮挡物的多种检修工况中,对输电塔的故障信息检测率均高于90%,可以满足使用需求,且适用性好、抗干扰性显著。To improve the transmission tower fault detection rate in strip operation,a Lidar-based helicopter basket method for electrical operation is proposed.Helicopter basket Lidar is used to collect transmission tower point cloud data.The weighted local optimization projection algorithm is used to denoise.D-S theory is used to classify multiple features,calculate feature similarity,and discriminate abnormal point cloud data.The test results show that the fault information detection rate of transmission towers by the Lidar-based helicopter basket method for electrical operation is higher than 90%in a variety of maintenance conditions where noise and obscurants exist,which can meet the use requirements and has good applicability and significant anti-interference.
