| description | The invention provides a method and equipment for detecting tree dangerous points in a power transmission line range. The method comprises the following steps: acquiring original point cloud data; after denoising the original point cloud data, generating first point cloud data; separating ground points in the first point cloud data to generate second point cloud data; generating a CHM of the treebased on the second point cloud data; carrying out single-tree segmentation on the CHM, and determining three-dimensional space parameters of a single tree; and based on the three-dimensional space parameters, the three-dimensional space position of the power transmission line and a preset safety margin, determining a dangerous point which is dangerous due to tree collapse. Whether dangers exist or not can be detected according to the distance relation between the tree and the power transmission line, and therefore effective recognition of possible dangers is achieved.
