Modelling of Marine Icing with Close Range Photogrammetry
AuthorHaukebø, Asbjørn Risholm
Installations and vessels operating in the high North in the winter season are likely to be subjected to marine Icing. To date there are no sensor technology available to accurately measure the total weight or volume of the ice. Photogrammetry is a universal 3-D measuring technique applied in a wide range of interdisciplinary fields. Agisoft PhotoScan is a photogrammetry software utilizing Structure From Motion(SFM) algorithm to create accurate 3-D mesh models. Scenes involving objects that are not textured, shiny, or transparent are to be avoided. The surface of marine ice has all of these properties. This thesis will investigate if, despite all recommendations not to, and show that the PhotoScan software is capable of creating an accurate 3-D model of a block of salt water ice. The volume of the ice model was calculated to be within less than 1% of the actual volume of the ice, using PhotoScan software.

Innovation and commercialization potential of university-developed arctic ice-tethered platforms. A case study of research-based technology Agwu, Ukeje Jacob; Logvinovskaya, Anna; Phetchpinkaew, Gorn (Master thesis; Mastergradsoppgave, 2017-05-31)The Arctic is a region which is rapidly opening up for business opportunities. However, research has been abundant here for a long time. With this situation comes the avenue to transition technology used in the region from research to commercial purposes. In this thesis, a business case is developed to show the commercial potential of research-based technology. The case technology was developed by ...
Marin forsøpling. Hvilke regler gjelder med formål å forhindre primærmikroplastforsøpling i norske kyst-og havområder Slungård, Andrea Øiahals (Master thesis; Mastergradsoppgave, 2016-05-03)Masteroppgaven omhandler primær mikroplastforsøpling som følge av norsk bruk eller virksomhet og tar utgangspunkt i forsøplingskildene av primær mikroplast som er kosmetikk, gummigranulat fra idrettsbaner og utilsiktet utslipp fra plastindustrien. Marin forsøpling, herunder primær mikroplastforsøpling betegnes om de bearbeidede og prosesserte faste stoffer som havner i kyst og havområdene Primær ...
On the use of the HUGIN 1000 HUS Autonomous Underwater Vehicle for high resolution zooplankton measurements Pedersen, Ole Petter; Gaardsted, Frank; Lågstad, Petter Arthur; Tande, Kurt Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)This paper evaluates and tests the HUGIN 1000 HUS AUV as a carrier platform for the Laser Optical Plankton Counter (LOPC). The LOPC was mounted outside on top of the carrier platform, and the tests confirm that this concept did not create turbulence and zooplankton avoidance. A negligible velocity difference between the flow passing through the sampling tube and the AUV speed was detected. The ...
