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 abovewaterportion of icebergs using surface imaging. The goal is to worktowards the automation of iceberg surveys allowing Unmanned SurfaceCraft to acquire shape and size information to fulfill the icebergdatabase. The presented methodology is made up of 3 parts: volumeintersection, occluding contour finding, data collection, and integration.This method is investigated in field trials conducted through thesummer of 2014 by surveying 8 icebergs during 3 expeditions.
