Improved particle swarm optimization algorithm based on a three-dimensional convex hull for fitting a screw thread central axis
2020
IEEE Access
To meet the needs of three-dimensional (3D) measurement and to achieve the high-precision fitting of the central axis of a screw thread, this study performed complex processing of the 3D structures on the surface of the thread central axis. Moreover, this study examined the problems of long processing time and low accuracy caused by the use of a point cloud with a large data volume. An improved particle swarm optimization algorithm was used to develop a fitting method for the central axis of
