Despite this need, there has been a noticeable absence of comprehensive investigations specifically dedicated to LPCC methods. To address this issue, this article presents a systematic survey of existing LPCCs, aiming to summarize recent progress and inspire future research in this field. We begin by providing a general introduction of LPCC fundamentals, covering the latest LiDAR point cloud (LPC) datasets, distinctive attributes, evaluation metrics, and data formats. We then conduct a careful review and comparison of LPCCs, examining image-based, octree-based, deep-learned, and other approaches, offering valuable insights into the strengths and weaknesses of cutting-edge models. Finally, we propose future research directions based on the limitations of recent LPCCs. We believe that the findings presented in this article will contribute to a deeper understanding of LPCCs and promote further development of LiDAR sensor-based systems.<\/jats:p>","DOI":"10.1145\/3715916","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T10:04:21Z","timestamp":1738317861000},"page":"1-31","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Compression Approaches for LiDAR Point Clouds and Beyond: A Survey"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1125-9299","authenticated-orcid":false,"given":"Miaohui","family":"Wang","sequence":"first","affiliation":[{"name":"Guangdong Key Laboratory of Intelligent Information Processing, College of Electronics and Information Engineering, Shenzhen University (SZU), Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0175-5910","authenticated-orcid":false,"given":"Runnan","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5791-8267","authenticated-orcid":false,"given":"Wuyuan","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Computer Science and Software Engineering, Shenzhen University, Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3686-4057","authenticated-orcid":false,"given":"Zhan","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Engineering, Nanjing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2731-5403","authenticated-orcid":false,"given":"Siwei","family":"Ma","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Video Technology, Peking University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2025,7,19]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2022.3167957"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/CVPR52729.2023.02138"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2023.3343096"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1117\/12.2556264"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/IV51971.2022.9827270"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/ICCV.2019.00939"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA48506.2021.9561476"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rse.2016.02.031"},{"key":"e_1_3_2_10_2","first-page":"22170","volume-title":"Proceedings of the International Conference on Neural Information Processing Systems (NeurIPS \u201920)","author":"Biswas Sourav","year":"2020","unstructured":"Sourav Biswas, Jerry Liu, Kelvin Wong, Shenlong Wang, and Raquel Urtasun. 2020.
