Rapid Reconstruction Method to 2D-Profiles Feature

The paper introduces a rapid and effective method to reconstruct 2D-profiles feature from data points. Firstly, the profiles point data are divided into lines points segments by incensement method, then fitting the points as lines saving lines parameters to line chain list; searching the line parameter chain list, if three are two continuous lines satisfy arc fitting conditions, computing the arc parameters by the two continuous lines, then saving the arc parameters to arc parameters chain list; searching arc parameters chin list, if there are two or more continuous arcs, turn these arcs to Bspline curves, profiles can be reconstructed by list feature elements, which benefits following surface reconstruction.
