However, the teleoperated robotic systems have significant limitations encouraging the ongoing development of autonomous unmanned aerial vehicles (UAVs). The autonomous robotic platforms provide a more accurate and safe measurement in distant and difficult to access areas than their teleoperated counterpart. Through the use of autonomous aerial robotic systems, access to such places by humans and building of external infrastructures like scaffolding for documentation purposes is no longer necessary. In this work, we aim to present a novel autonomous unmanned aerial vehicle designed for the documentation of hardly attainable areas of historical buildings. The prototype of this robot was tested in several historical monuments comprising scanned objects located in dark and hardly accessible areas in the upper parts of tall naves. This manuscript presents the results from two specific places: the Church of St. Anne and St. Jacob the Great in Star\u00e1 Voda, and St. Maurice Church in Olomouc, both in the Czech Republic. Finally, we also compare the three-dimensional map obtained with the measurements made by the 3D laser scanner carried onboard UAV against the ones performed by a 3D terrestrial laser scanner.<\/jats:p>","DOI":"10.3390\/ijgi10110738","type":"journal-article","created":{"date-parts":[[2021,11,1]],"date-time":"2021-11-01T22:21:34Z","timestamp":1635805294000},"page":"738","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Safe Documentation of Historical Monuments by an Autonomous Unmanned Aerial Vehicle"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1914-742X","authenticated-orcid":false,"given":"V\u00edt","family":"Kr\u00e1tk\u00fd","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University in Prague, 166 36 Prague, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0887-9430","authenticated-orcid":false,"given":"Pavel","family":"Petr\u00e1\u010dek","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University in Prague, 166 36 Prague, Czech Republic"}]},{"given":"Tiago","family":"Nascimento","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University in Prague, 166 36 Prague, Czech Republic"}]},{"given":"Michaela","family":"\u010cadilov\u00e1","sequence":"additional","affiliation":[{"name":"Czech National Heritage Institute, 799 00 Olomouc, Czech Republic"}]},{"given":"Milan","family":"\u0160kobrtal","sequence":"additional","affiliation":[{"name":"Czech National Heritage Institute, 799 00 Olomouc, Czech Republic"}]},{"given":"Pavel","family":"Stoudek","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University in Prague, 166 36 Prague, Czech Republic"}]},{"given":"Martin","family":"Saska","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University in Prague, 166 36 Prague, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bentkowska-Kafel, A., and MacDonald, L.
