Abstract

This paper reports on current research to automate the task of ship hull inspection and search using autonomous underwater vehicles (AUVs). We describe an automated feature-based navigation (FBN) and mapping framework that provides the AUV with precise in-situ hull-relative localization. Our vision-based perception approach eliminates the need for having to deploy additional navigation infrastructure, such as acoustic beacons (a traditional method for obtaining precise bounded-error navigation). We describe our mapping framework and show how we are now applying that framework to the task of automated ship-hull inspection using the HAUV testbed. The operational impact to the Navy of this technology development will be rapid, repeatable, automated 100% survey coverage for ship-hull inspection.
