Abstract

This paper concentrates on creating precise, measurable and textured three-dimensional (3D) models of coastal boulders without physical contact with the object, based on multi-view image measurement techniques. The AA. propose the use of low-cost equipment (digital cameras) that can be used in various coastal environments to easily acquire numerous images of the object of interest. Initial results can be rapidly assessed in the field for immediate quality control. Resulting 3D models, built from overlapping multi-view digital photographs, allow the reconstruction of realistic-looking and textured boulder surfaces. A particular interest in this task is the family of algorithms known as structure from motion (SFM). The work presents analysis of SFM techniques by examining 3D models of boulders observed at a coastal field site on Lu Dao Island in south-eastern Taiwan
