This paper investigates the system behaviour of the VR system HTC Vive Pro at a testing facility that is designed for the calibration of highly accurate positioning instruments like geodetic total stations, tilt sensors, geodetic gyroscopes or industrial laser scanners. Although the experiments show a high reproducibility of the position readings within a few millimetres, the VR system has systematic effects with magnitudes of several centimetres. A tilt of about 0.4\u00b0 of the reference plane with respect to the horizontal plane was detected. Moreover, our results demonstrate that the tracking algorithm faces problems when several lighthouses are used.<\/jats:p>","DOI":"10.3390\/s21051622","type":"journal-article","created":{"date-parts":[[2021,2,26]],"date-time":"2021-02-26T04:36:24Z","timestamp":1614314184000},"page":"1622","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Accuracy Investigation of the Pose Determination of a VR System"],"prefix":"10.3390","volume":"21","author":[{"given":"Peter","family":"Bauer","sequence":"first","affiliation":[{"name":"Institute of Engineering Geodesy and Measurement Systems, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2523-4052","authenticated-orcid":false,"given":"Werner","family":"Lienhart","sequence":"additional","affiliation":[{"name":"Institute of Engineering Geodesy and Measurement Systems, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Jost","sequence":"additional","affiliation":[{"name":"Institute of Engineering Geodesy and Measurement Systems, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Levin, E., Shults, R., Habibi, R., An, Z., and William, R.W.
