چکیده
To meet the needs of three-dimensional (3D) measurement and to achieve high-precision fitting central axis a screw thread, this study performed complex processing 3D structures on surface thread axis. Moreover, examined problems long time low accuracy caused by use point cloud with large data volume. An improved particle swarm optimization algorithm was used develop method for convex hull. SolidWorks simulate parts standard Point Cloud Library generate simulated surface. The maximum deviation between fitted line obtained in two-dimensional (2D) projection 0.12 μm. experiment conducted using regarding tip plug gauge variation distance straight smaller than that 2D cloud. calculation speed higher when method.
