ABSTRACT

The expedition Oden Arctic Technology Research Cruise 2015 was carried out by the Norwegian University of Science and Technology in collaboration with the Swedish Polar Research Secretariat. Two icebreakers, Oden and Frej, were employed during this research cruise into the Arctic Ocean. Among many research activities, the extraction of sea ice information is of great importance. Sea ice concentration is an important parameter for the calculations of ice actions and its effect on Arctic marine structures and for the evaluation of icebreaker performance. Various methods exist nowadays to monitor these parameters, ranging from geophysical scale to local scale. The Ice Concentration camera is looking obliquely toward the ship transiting direction. The obtained image is therefore distorted with more or less pixels in the near or far field. A perspective rectification process is needed to project the originally captured image onto the sea plane.
