Extraction of the Lines of Curvature from Raw Point Cloud

摘要

A new method for direct extraction of the lines of curvature from raw point clouds is presented in this paper. We first extract smooth and continue direction fields by applying surface fitting algorithm. And then a priority queue is established according to the curvatures of each point for extracting lines of curvature in a feature-preserving manner. The approach is performed without computing an explicit parameterization of the surface, and is thus applicable to manifolds of any genus. Experiments on various 3D point set are implemented to verify its feasibility and performance.
