Detection method for strain clamp of power transmission line

The invention relates to a detection method for a strain clamp of a power transmission line, and the method comprises the following steps: 1), obtaining the spatial point cloud data of the strain clamp, converting the spatial point cloud data into a. Txt file form, and building a point cloud model; 2) adopting a statistical filtering algorithm to realize denoising of the point cloud model, and adopting a curvature feature-based gridding simplification method to realize simplification of the point cloud model; 3) adopting an RANSAC (Random Sample Consensus) algorithm to realize clustering segmentation of the point cloud model; 4) performing model fitting on the point cloud data by adopting an NURBS curved surface fitting method so as to realize three-dimensional model reconstruction of the strain clamp; and 5) realizing registration between the tested strain clamp and the standard strain clamp according to the characteristic surface equation of the strain clamp, and calculating the characteristic ...
