The recent advent of Unmanned Aerial Vehicles (UAVs), in combination with coastal video monitoring techniques, allows for an alternative and low cost evaluation of the nearshore bathymetry. Camera calibration and stabilization is a critical issue in bathymetry estimation from video systems. This work introduces a new methodology in order to obtain such bathymetries, and it compares the results to echo-sounder ground truth data. The goal is to gain a better understanding on the influence of the camera calibration and stabilization on the inferred bathymetry. The results show how the proposed methodology allows for accurate evaluations of the bathymetry, with overall root mean square errors in the order of 40 cm. It is shown that the intrinsic calibration of the camera, related to the lens distortion, is the most critical aspect. Here, the intrinsic calibration that was obtained directly during the flight yields the best results.<\/jats:p>","DOI":"10.3390\/rs13010150","type":"journal-article","created":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T10:35:12Z","timestamp":1609842912000},"page":"150","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The Influence of Camera Calibration on Nearshore Bathymetry Estimation from UAV Videos"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6420-5975","authenticated-orcid":false,"given":"Gonzalo","family":"Simarro","sequence":"first","affiliation":[{"name":"Instituto de Ciencias del Mar (ICM, CSIC), Passeig Mar\u00edtim de la Barceloneta 37-49, 08003 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5402-5137","authenticated-orcid":false,"given":"Daniel","family":"Calvete","sequence":"additional","affiliation":[{"name":"Department of Physics, Universitat Polit\u00e8cnica de Catalunya, Jordi Girona 1-3, 08034 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9819-0927","authenticated-orcid":false,"given":"Theocharis A.","family":"Plomaritis","sequence":"additional","affiliation":[{"name":"Department of Applied Physics, Instituto Universitario de Investigaci\u00f3n Marina (INMAR), Campus de Excelencia Internacional\/Global del Mar (CEI-MAR), University of Cadiz, 11510 Puerto Real, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8640-684X","authenticated-orcid":false,"given":"Francesc","family":"Moreno-Noguer","sequence":"additional","affiliation":[{"name":"Institut de Rob\u00f2tica i Inform\u00e0tica Industrial (IRI, CSIC-UPC), Llorens i Artigas 4-6, 08028 Barcelona, Spain"}]},{"given":"Ifigeneia","family":"Giannoukakou-Leontsini","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias del Mar (ICM, CSIC), Passeig Mar\u00edtim de la Barceloneta 37-49, 08003 Barcelona, Spain"},{"name":"Department of Applied Physics, Instituto Universitario de Investigaci\u00f3n Marina (INMAR), Campus de Excelencia Internacional\/Global del Mar (CEI-MAR), University of Cadiz, 11510 Puerto Real, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0365-5155","authenticated-orcid":false,"given":"Juan","family":"Montes","sequence":"additional","affiliation":[{"name":"Department of Earth Science, Instituto Universitario de Investigaci\u00f3n Marina (INMAR), Campus de Excelencia Internacional\/Global del Mar (CEI-MAR), University of C\u00e1diz, 11510 Puerto Real, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7423-1069","authenticated-orcid":false,"given":"Ruth","family":"Dur\u00e1n","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias del Mar (ICM, CSIC), Passeig Mar\u00edtim de la Barceloneta 37-49, 08003 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1061\/(ASCE)0733-9453(1984)110:1(1)","article-title":"The crab: A unique nearshore surveying vehicle","volume":"110","author":"Birkemeier","year":"1984","journal-title":"J.
