In this paper, we propose an on-orbit calibration method for the relative installation attitude of the camera and the LiDAR with no need for the calibration field and additional satellite attitude maneuvers. Firstly, the on-orbit joint calibration model of the relative installation attitude of the two sensors is established. However, there may exist a multi-solution problem in the solving of the above model constrained by non-ground control points. Thus, an alternate iterative method by solving the pseudo-absolute attitude matrix of each sensor in turn is proposed. The numerical validation and simulation experiments results show that the relative positioning error of the line array camera and the LiDAR in the horizontal direction of the ground can be limited to 0.8 m after correction by the method in this paper.<\/jats:p>","DOI":"10.3390\/rs14122949","type":"journal-article","created":{"date-parts":[[2022,6,21]],"date-time":"2022-06-21T04:39:55Z","timestamp":1655786395000},"page":"2949","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["On-Orbit Calibration for Spaceborne Line Array Camera and LiDAR"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3187-9268","authenticated-orcid":false,"given":"Xiangpeng","family":"Xu","sequence":"first","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5332-5501","authenticated-orcid":false,"given":"Sheng","family":"Zhuge","sequence":"additional","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]},{"given":"Banglei","family":"Guan","sequence":"additional","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410073, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7734-2151","authenticated-orcid":false,"given":"Bin","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]},{"given":"Shuwei","family":"Gan","sequence":"additional","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]},{"given":"Xia","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4907-1451","authenticated-orcid":false,"given":"Xiaohu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Aeronautics and Astronautics, Sun Yat-sen University, Guangzhou 510275, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1016\/j.geomorph.2017.11.005","article-title":"The application of LiDAR to investigate foredune morphology and vegetation","volume":"303","author":"Doyle","year":"2018","journal-title":"Geomorphology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"103765","DOI":"10.1016\/j.landurbplan.2020.103765","article-title":"Application of airborne LiDAR and GIS in modeling trail erosion along the Appalachian Trail in New Hampshire, USA","volume":"198","author":"Eagleston","year":"2020","journal-title":"Landsc.
