A cloud acquired using a static scanner Leica ScanStation P40 served as a reference. Clouds from both scanners were registered into the same coordinate system using a Trimble S9 HP total station. SLAM scanner acquisition was performed independently in two passes. The data acquired using the SLAM scanner suffered from relatively high noise. Denoising using the MLS (Moving Least Squares) method was performed to reduce noise. An overall comparison of the point clouds was performed on both the original and MLS-smoothed data. In addition, the ICP (Iterative Closest Point) algorithm was also used to evaluate local accuracy. The RMSDs of MLS-denoised data were approximately 0.02 m for both GeoSLAM passes. Subsequently, a more detailed analysis was performed, calculating RMSDs for several profiles of the construction. This analysis revealed that the deviations of SLAM data from the reference data did not exceed 0.03 m in any direction (longitudinal, transverse, elevation) which is, considering the length of the bridge of 133 m, a very good result. These results demonstrate a high applicability of the tested scanner for many applications, such as the creation of digital twins.<\/jats:p>","DOI":"10.3390\/app14125258","type":"journal-article","created":{"date-parts":[[2024,6,18]],"date-time":"2024-06-18T03:42:06Z","timestamp":1718682126000},"page":"5258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Determination of Accuracy and Usability of a SLAM Scanner GeoSLAM Zeb Horizon: A Bridge Structure Case Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0996-1241","authenticated-orcid":false,"given":"Rudolf","family":"Urban","sequence":"first","affiliation":[{"name":"Department of Special Geodesy, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 16629 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0070-7172","authenticated-orcid":false,"given":"Martin","family":"\u0160troner","sequence":"additional","affiliation":[{"name":"Department of Special Geodesy, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 16629 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaroslav","family":"Braun","sequence":"additional","affiliation":[{"name":"Department of Special Geodesy, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 16629 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom\u00e1\u0161","family":"Suk","sequence":"additional","affiliation":[{"name":"Department of Special Geodesy, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 16629 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4763-1013","authenticated-orcid":false,"given":"\u013dudov\u00edt","family":"Kovani\u010d","sequence":"additional","affiliation":[{"name":"Institute of Geodesy, Cartography and Geographical Information Systems, Faculty of Mining, Ecology, Process Control and Geotechnologies, Technical University Kosice, Park Komensk\u00e9ho 19, 04001 Ko\u0161ice, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8452-3532","authenticated-orcid":false,"given":"Peter","family":"Blistan","sequence":"additional","affiliation":[{"name":"Institute of Geodesy, Cartography and Geographical Information Systems, Faculty of Mining, Ecology, Process Control and Geotechnologies, Technical University Kosice, Park Komensk\u00e9ho 19, 04001 Ko\u0161ice, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"\u0160troner, M., K\u0159emen, T., and Urban, R.
