The invention discloses a laser point cloud-based transmission tower extraction method and system, and the method comprises the steps: obtaining laser point cloud data, carrying out the basic processing of the laser point cloud data, and rapidly filtering a tower according to the processed point cloud data and the spatial features of the point cloud, so as to carry out the rough extraction and fine extraction of the tower. Compared with similar patents, all towers can be rapidly separated from huge point cloud data, coordinates of all towers can be obtained, meanwhile, the method is suitable for tower extraction of various terrains such as mountainous regions, hills and plains, excessive manual intervention is not needed, all towers in a section of line can be automatically separated and extracted through an algorithm process, and the extraction efficiency is improved. And finally, the tower point cloud is restored for flight path planning of fine inspection of the unmanned aerial vehicle. 一种基于激光点云的输电杆塔提取方法及系
