A scattered point cloud data edge detection algorithm is designed to extract edge features quickly and accurately.The algorithm is based on the local characteristics of the point cloud.By analyzing the characteristics of the normal vector of each point of the point cloud data,the k-nearest neighbor normal angle feature,the curvature feature,and the distance feature of each point are constructed to complete the point cloud edge feature detection under the constraint of the Gaussian function.Using public data to conduct multiple sets of experiments to compare the detection effects of different algorithms.The results show that the proposed algorithm is faster and better at extracting edge features of point clouds.
