However, the assumption that geometrical changes when the molten material is in free-fall can be correlated with material characteristics such as viscosity opens the door to a highly accurate contactless method characterizing small dynamic changes. This paper proposes multi-camera setup to achieve accuracy close to the segmentation error associated with the resolution of the images. The experimental setup presented shows that the geometrical parameters can be characterized dynamically through the whole free-fall process at a frame rate of 600 frames per second. The results achieved show the proposed multi-camera setup is suitable for estimating the length of free-falling molten objects.<\/jats:p>","DOI":"10.3390\/s21041041","type":"journal-article","created":{"date-parts":[[2021,2,3]],"date-time":"2021-02-03T20:31:51Z","timestamp":1612384311000},"page":"1041","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Multi-Camera Based Setup for Geometrical Measurement of Free-Falling Molten Glass Gob"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8776-2985","authenticated-orcid":false,"given":"Mazhar","family":"Hussain","sequence":"first","affiliation":[{"name":"STC Research Centre, Mid-Sweden University, Holmgatan 10, 85170 Sundsvall, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8607-4083","authenticated-orcid":false,"given":"Mattias","family":"O\u2019Nils","sequence":"additional","affiliation":[{"name":"STC Research Centre, Mid-Sweden University, Holmgatan 10, 85170 Sundsvall, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1819-6200","authenticated-orcid":false,"given":"Jan","family":"Lundgren","sequence":"additional","affiliation":[{"name":"STC Research Centre, Mid-Sweden University, Holmgatan 10, 85170 Sundsvall, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,3]]},"reference":[{"key":"ref_1","unstructured":"Kieffer, J.
