A Method of Above-water Iceberg 3D Modelling Using Surface Imaging

摘要

This paper reports on an algorithm to build a 3-D model of the abovewater portion of icebergs using surface imaging. The goal is to work towards the automation of iceberg surveys allowing Unmanned Surface Craft to acquire shape and size information to fulfill the iceberg database. The presented methodology is made up of 3 parts: volume intersection, occluding contour finding, data collection, and integration. This method is investigated in field trials conducted through the summer of 2014 by surveying 8 icebergs during 3 expeditions.
