Power transmission line distance measurement method, device and system based on ground fixed-point laser radar scanning and electronic equipment

The invention discloses a power transmission line distance measurement method, device and system based on ground fixed-point laser radar scanning and electronic equipment. The method comprises the steps: acquiring point cloud data of a power transmission line; preprocessing the point cloud data; constructing a point cloud three-dimensional model according to the preprocessed point cloud data; acquiring two to-be-measured points input into the point cloud three-dimensional model; and calculating the distance between the two points to be measured. On the basis of a point cloud measurement mode,modeling can be carried out on the point cloud of a conical surface scanned by a power transmission line at a time, the target safety distance is directly judged in a three-dimensional space or the system automatically calculates and gives an alarm, and the operation efficiency and the convenience degree are greatly improved. 本发明公开了一种基于地面定点激光雷达扫描的输电线距离测量方法、装置、系统和电子设备，所述方法包括：获取输电线路的点云数据；对所述点云数据进行预处理；根据预处理后的所述点云数据构建点云三维模型；获
