Fluid environments can be monitored experimentally through Particle Image Velocimetry (PIV), whereas recent technological developments allow endowing underwater robots with flow-sensing capabilities.

In this context, we present a PIV post-processing toolbox developed with the intention of bringing the observation point into the flow-to support exploring the sensing picture in a given flow environment, as well as characterizing the flow regime.

Abstract
Fluid environments can be monitored experimentally through Particle Image Velocimetry (PIV), whereas recent technological developments allow endowing underwater robots with flow-sensing capabilities. This combination opens the way to designing for context-aware robot navigation. However, such innovation demands that flow analysis be carried out from a situated perspective, rather than from the traditional bird's eye view. In this context, we present a PIV post-processing toolbox developed with the intention of bringing the observation point into the flow-to support exploring the sensing picture in a given flow environment, as well as characterizing the flow regime. In order to show how the toolbox can address questions emerging from a situated perspective, we present a case-study in regime-specific feature extraction.File | Dimensione | Formato | |
