In this paper, we propose fast image mosaicking using a triangulated irregular network (TIN) constructed from tiepoints. We conduct pairwise tiepoint extraction and rigorous bundle adjustment to generate rigorous tiepoints. We apply a bucketing algorithm to the tiepoints and generate evenly distributed tiepoints. We then construct a TIN from the bucketed tiepoints and extract seamlines for image stitching based on the TIN. Image mosaicking is completed by mapping UAV images along the seamlines onto a reference plane. The experimental results showed that the image mosaicking based on a TIN of bucketed tiepoints could produce image mosaics with stable and fast performance. We expect that our method could be used for rapid image mosaicking.<\/jats:p>","DOI":"10.3390\/rs15245782","type":"journal-article","created":{"date-parts":[[2023,12,18]],"date-time":"2023-12-18T10:04:47Z","timestamp":1702893887000},"page":"5782","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Fast UAV Image Mosaicking by a Triangulated Irregular Network of Bucketed Tiepoints"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8939-7854","authenticated-orcid":false,"given":"Sung-Joo","family":"Yoon","sequence":"first","affiliation":[{"name":"Department of Geoinformatic Engineering, Inha University, Incheon 22212, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4083-7409","authenticated-orcid":false,"given":"Taejung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Geoinformatic Engineering, Inha University, Incheon 22212, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1109\/MGRS.2019.2921780","article-title":"Remote sensing image mosaicking: Achievements and challenges","volume":"7","author":"Li","year":"2019","journal-title":"IEEE Geosci.
