Abstract:In order to solve problems that exist in recovering datasets topology and retrieving features from point clouds,a
new surface reconstruction method for piecewise smooth surfaces from point clouds is ,assemble a graph of lo-
cal surface patches consisting of a set of basis functions,then establish topological connectivity among the nodes that re-
spect sharp features,the last,search optimal coefficients for the basis functions in each node by solving a sparse optimiza-
tion final representation allowes for robust finding of crease and border edges which separate the piecewise
smooth output of the new method,a clean,manifold surface mesh which preserves feature lines is ex-
perimental results show the effectiveness of the method with reconstructions of piecewise smooth surfaces.
Key words:piecewise smooth surfaces;patch-graph;sparse optimization;feature points;feature lines;segmentation;energy function
