We present the luminance calibration of a laser scanner and assess the accuracy, color measurement properties, and dynamic range of luminance measurement achieved in the laboratory environment. In addition, we demonstrate the 3D luminance measuring process through a case study with a luminance-calibrated laser scanner. The presented method can be utilized directly as the luminance data source. A terrestrial laser scanner can be prepared, characterized, and calibrated to apply it to the simultaneous measurement of both geometry and luminance. We discuss the state and limitations of contemporary TLS technology for luminance measuring.<\/jats:p>","DOI":"10.3390\/jimaging7050085","type":"journal-article","created":{"date-parts":[[2021,5,10]],"date-time":"2021-05-10T10:49:51Z","timestamp":1620643791000},"page":"85","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Utilizing a Terrestrial Laser Scanner for 3D Luminance Measurement of Indoor Environments"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4380-3885","authenticated-orcid":false,"given":"Matti","family":"Kurkela","sequence":"first","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6609-372X","authenticated-orcid":false,"given":"Mikko","family":"Maksimainen","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9887-1573","authenticated-orcid":false,"given":"Arttu","family":"Julin","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3781-7204","authenticated-orcid":false,"given":"Toni","family":"Rantanen","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0281-9717","authenticated-orcid":false,"given":"Juho-Pekka","family":"Virtanen","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"},{"name":"Finnish Geospatial Research Institute FGI, Geodeetinrinne 2, FI-02430 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5360-4017","authenticated-orcid":false,"given":"Juha","family":"Hyypp\u00e4","sequence":"additional","affiliation":[{"name":"Finnish Geospatial Research Institute FGI, Geodeetinrinne 2, FI-02430 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9907-0516","authenticated-orcid":false,"given":"Matti Tapio","family":"Vaaja","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2487-3159","authenticated-orcid":false,"given":"Hannu","family":"Hyypp\u00e4","sequence":"additional","affiliation":[{"name":"Department of Built Environment, School of Engineering, Aalto University, FI-00076 Aalto, Finland"},{"name":"Finnish Geospatial Research Institute FGI, Geodeetinrinne 2, FI-02430 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Park, J., Zhou, Q.Y., and Koltun, V.
