Title: Development and uncertainty characterization of 3D particle location from perspective shifted plenoptic images

Abstract

This work details the development of an algorithm to determine 3D position and in plane size and shape of particles by exploiting the perspective shift capabilities of a plenoptic camera combined with stereo-matching methods. This algorithm is validated using an experimental data set previously examined in a refocusing based particle location study in which a static particle field is translated to provide known depth displacements at varied magnification and object distances. Examination of these results indicates increased accuracy and precision is achieved compared to a previous refocusing based method at significantly reduced computational costs. Furthermore the perspective shift method is further applied to fragment localization and sizing in a lab scale fragmenting explosive.
