| description | The invention discloses a laser point cloud automatic classification method for key elements of a high-voltage overhead transmission line, and relates to the technical field of overhead transmission lines, and the method comprises the steps: S1, collecting point cloud data of the high-voltage overhead transmission line, and carrying out the preprocessing of the collected point cloud data through employing the standing book information of the overhead line; s2, for the preprocessed point cloud data, separating ground point cloud data and non-ground point cloud data by adopting a triangulated irregular network TIN progressive encryption filtering algorithm; s3, performing point cloud smoothing processing on the ground point cloud data by adopting a weighted least square method; and S4, performing fine classification and extraction on the non-ground point cloud data by using different algorithms. According to the method, the triangulated irregular network TIN progressive encryption filtering algorithm is adopted |
