| Zusammenfassung: | The invention provides a power transmission channel tree obstacle hidden danger detection method based on 3D point cloud, and belongs to the technical field of power transmission channel tree obstacle hidden danger detection. The technical problem to be solved is to provide the improvement of the power transmission channel tree obstacle hidden danger detection method based on the 3D point cloud. According to the technical scheme adopted for solving the technical problem, interference point clouds, existing in original point cloud data of a power transmission channel, of the ground, buildings and trees are filtered through an elevation histogram filtering method based on a normalized digital surface model, and the point cloud data of the power transmission channel are preliminarily extracted and preprocessed; performing power transmission line point cloud extraction on the point cloud data after data preprocessing, performing tree obstacle detection on the power transmission line, specifically measuring the di |
