In this paper, a point cloud quality optimization and enhancement algorithm is designed. A self\u2010adaptive octree is established to rasterize the point cloud and calculate the density of each grid, combing with the statistical filtering to remove outliers from the point cloud data. Then, a plane projection method is used for removing the confounding points from the point cloud data. Finally, the point cloud is triangulated and a priority value is set, and then, points are preferentially inserted where the priority value is the largest to repair the holes. Experiments show that while removing outliers and confounding points, the detailed features of the point cloud can be maintained, holes are effectively filled, and the quality of the point cloud is effectively improved.<\/jats:p>","DOI":"10.1155\/2021\/7325600","type":"journal-article","created":{"date-parts":[[2021,12,7]],"date-time":"2021-12-07T01:35:06Z","timestamp":1638840906000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Optimization Algorithm for Point Cloud Quality Enhancement Based on Statistical Filtering"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3226-1689","authenticated-orcid":false,"given":"Qian","family":"Zhao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaorong","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2724-7807","authenticated-orcid":false,"given":"Jinlong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,12,6]]},"reference":[{"key":"e_1_2_8_1_2","article-title":"Automatic recognition of bolts on locomotive running gear based on laser scanner 3D measurement[J]","volume":"45","author":"Qian H.","year":"2018","journal-title":"Opto-electronic Engineering"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/cgf.12187"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/2421636.2421645"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/1687814018814330"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.isprsjprs.2018.03.010"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/s40965-018-0056-5"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2018.10.013"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12524-021-01397-4"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1145\/1073204.1073227"},{"key":"e_1_2_8_10_2","article-title":"Parameterization-free projection for geometry reconstruction[C]","volume":"22","author":"Lipman Y.","year":"2007","journal-title":"Proceedings of International Conference on Computer Graphics and Interactive Techniques (ACM SIGGRAPH 2007)"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1145\/1618452.1618522"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.robot.2008.08.005"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0201280"},{"key":"e_1_2_8_14_2","unstructured":"EsterM.
