In response to the above problem this paper carries out the research on multi-sensor fusion localization algorithm, the main work is as follows: Based on ORB-SLAM3, a visual-inertial-laser SLAM algorithm is designed. The relative motion of laser location between image frames is obtained from the data of 2D Lidar and laser height sensor. The relative motion of inertial measurement unit between image frames is obtained from inertial measurement unit preintegration. Based on the method of factor graph optimization, the pose of image frame is optimized by reprojection of map point, relative motion increment of inertial measurement unit, and relative motion increment of laser location. The algorithm improves the localization accuracy by about 24.4% over the ORB-SLAM3 visual mode and about 22.6% over the ORB-SLAM3 visual-inertial mode on the data of the UAV physical platform. <\/jats:p>","DOI":"10.1142\/s2301385024500262","type":"journal-article","created":{"date-parts":[[2023,4,21]],"date-time":"2023-04-21T06:44:05Z","timestamp":1682059445000},"page":"903-912","source":"Crossref","is-referenced-by-count":2,"title":["Visual-Inertial-Laser SLAM Based on ORB-SLAM3"],"prefix":"10.1142","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0874-1893","authenticated-orcid":false,"given":"Meng","family":"Cao","sequence":"first","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9286-6420","authenticated-orcid":false,"given":"Wenjie","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100081, P.\u00a0R.\u00a0China"},{"name":"Beijing Institute of Technology Chongqing Innovation Center, Chongqing 401120, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2023,4,20]]},"reference":[{"key":"S2301385024500262BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA.2019.8793604"},{"key":"S2301385024500262BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/LRA.2017.2653359"},{"key":"S2301385024500262BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2018.2853729"},{"key":"S2301385024500262BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA.2018.8462905"},{"key":"S2301385024500262BIB005","doi-asserted-by":"publisher","DOI":"10.3390\/s19102251"},{"key":"S2301385024500262BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2021.3075644"},{"key":"S2301385024500262BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA48506.2021.9561149"},{"key":"S2301385024500262BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/IROS40897.2019.8967746"},{"key":"S2301385024500262BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/IROS45743.2020.9340704"},{"key":"S2301385024500262BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA48506.2021.9561996"},{"key":"S2301385024500262BIB011","doi-asserted-by":"publisher","DOI":"10.1109\/LRA.2021.3095515"},{"issue":"40","key":"S2301385024500262BIB012","first-page":"621","volume":"5","author":"Shah S.","year":"2017","journal-title":"Field Serv.
