However, existing globally consistent normal estimation (GCNO) methods are often limited by reduced accuracy and high computational cost when applied to complex models. To address these challenges, we propose a fast and robust point cloud normal estimation method guided by curvature information. The proposed method integrates curvature as a geometric prior into a global winding\u2010number\u2010based optimization formulation, effectively enhancing normal orientation consistency while preserving sharp geometric features. Furthermore, to improve computational efficiency, we introduce a PCA\u2010based visibility\u2010aware initialization strategy. This strategy adaptively adjusts the initial normal directions by leveraging the local geometric distribution of points, thereby enhancing the consistency of initial normal orientations. Experimental results demonstrate that, compared to the state\u2010of\u2010the\u2010art GCNO method, the proposed approach significantly improves both the accuracy and efficiency of normal estimation. This work provides an effective and precise solution for achieving globally consistent normal estimation in point clouds.<\/jats:p>","DOI":"10.1002\/cpe.70307","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T01:29:46Z","timestamp":1759109386000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Curvature\u2010Guided Fast and Robust Normal Estimation for Point Clouds"],"prefix":"10.1002","volume":"37","author":[{"given":"Mingxiu","family":"Tuo","sequence":"first","affiliation":[{"name":"School of Computer Science Northwest University  Xi'an China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Puyu","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Computer Science Northwest University  Xi'an China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyu","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Computer Science Northwest University  Xi'an China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haonan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science Northwest University  Xi'an China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4180-1341","authenticated-orcid":false,"given":"Shunli","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science Northwest University  Xi'an China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,28]]},"reference":[{"issue":"4","key":"e_1_2_10_2_1","first-page":"61","article-title":"Poisson Surface Reconstruction","volume":"7","author":"Kazhdan M.","year":"2006","journal-title":"Proceedings of the Fourth Eurographics Symposium on Geometry Processing"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8659.2011.02058.x"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-58604-1_1"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/IROS.2015.7353455"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/rs9050433"},{"key":"e_1_2_10_7_1","doi-asserted-by":"crossref","unstructured":"F.Cole K.Genova A.Sud et al. \u201cDifferentiable Surface Rendering via Non\u2010Differentiable Sampling \u201dProceedings of the IEEE\/CVF International Conference on Computer Vision (2021) 6088\u20136097.","DOI":"10.1109\/ICCV48922.2021.00603"},{"key":"e_1_2_10_8_1","doi-asserted-by":"crossref","unstructured":"H.Hoppe T.DeRose andT.Duchamp \u201cSurface Reconstruction From Unorganized Points \u201dProceedings of the 19th Annual Conference on Computer graphics and Interactive Techniques (1992) 71\u201378.","DOI":"10.1145\/133994.134011"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1109\/TIFS.2025.3528222"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/TIFS.2025.3527357"},{"key":"e_1_2_10_11_1","first-page":"92","article-title":"Consistent Propagation of Normal Orientations in Point Clouds","volume":"83","author":"K\u00f6nig S.","year":"2009","journal-title":"VMV"},{"key":"e_1_2_10_12_1","unstructured":"H.Xie J.Wang J.Hua et al. \u201cPiecewise C\/sup 1\/Continuous Surface Reconstruction of Noisy Point Clouds via Local Implicit Quadric Regression \u201dIEEE Visualization (2003) VIS 2003 IEEE 91\u201398."},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cag.2011.03.012"},{"key":"e_1_2_10_14_1","doi-asserted-by":"crossref","unstructured":"F.Hou C.Wang W.Wang et al. \u201cIterative Poisson Surface Reconstruction (iPSR) for Unoriented Points \u201darXiv Preprint arXiv:2209.09510 (2022).","DOI":"10.1145\/3528223.3530096"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1145\/3554730"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/cgf.12983"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/cgf.13343"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cad.2022.103281"},{"issue":"4","key":"e_1_2_10_19_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1145\/3592129","article-title":"Globally Consistent Normal Orientation for Point Clouds by Regularizing the Winding\u2010Number Field","volume":"42","author":"Xu R.","year":"2023","journal-title":"ACM Transactions on Graphics (TOG)"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.2017.2648803"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1137\/20M1314525"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1145\/3727873"},{"key":"e_1_2_10_23_1","unstructured":"M.Alexa J.Behr D.Cohen\u2010Or et al. \u201cPoint Set Surfaces \u201dProceedings Visualization 2001.
