Robust resistance to noise and outliers: Screened Poisson Surface Reconstruction using adaptive kernel density estimation

摘要

Screened Poisson Surface Reconstruction has a good performance among the state-of-art surface recon-struction algorithms in obtaining a triangle mesh from oriented points. In order to better deal with nonuniform point clouds, Screened Poisson Surface Reconstruction uses B-spline functions with a fixed support for kernel density estimation to construct a vector field for solving the screened Poisson equa-tion. In this paper, an adaptive bandwidth Gaussian kernel density estimator is applied, which reduces the bandwidth where the density is low, and increases the bandwidth where the density is high. Ex-periments show that such an estimator that makes use of both global and local points distribution can effectively remove noise and outliers in the reconstruction.(c) 2021 Elsevier Ltd.
