Reconstructing a Mesh from a Point Cloud by Using a Moving Parabolic Approximation

摘要

We use a moving parabolic approximation (MPA) to reconstruct a triangular mesh approximating the underlying surface of a point cloud. We suggest an efficient procedure to generate an initial mesh from a point cloud of closed shape. Then we refine this mesh selectively by comparing estimates of curvature from the point cloud with curvatures computed from the current mesh. We present several examples which demonstrate robustness of our method in the presence of noise, and show that the resulting reconstructions preserve geometric detail.
