Abstract

This paper investigates the problem of confirming the identity of a candidate object (expected to be a target based on some crude visual clues) with a mobile robot equipped with visual sensing capabilities. We present a method whose main novelty is to mix localization of the robot relative to the candidate object and to confirm that it is the sought target. This twofold approach drastically reduces false positives. Identity confirmation with this twofold goal is modeled as a Partially-Observable Markov Decision Process, where the states are the cells of the space decomposition. It is solved using Stochastic Dynamic Programming with imperfect state information. A robotic system using this method has been implemented and tests have been carried out both in simulation and with a real robot. The experiments empirically validate the use of various metrics, and demonstrate their ability to perform well in different settings.

• Object identification
• motion strategies
• appearance-guided motion
• robot localization
