Visual Detection with Hyperstereoscopic Video for Aerial Search and Rescue

Abstract

This paper summarises the results of two laboratory studies conducted to explore the potential benefits of hyperstereoscopic video for aerial search and rescue (SAR). The studies were conducted using a single camera hyperstereoscopic video system (designed for aerial SAR) as the test platform. The first study was designed to evaluate potential benefits of hyperstereopsis provided by large viewpoint separation. It was found that individual differences play an important role in defining a possible “optimal” viewpoint separation for the system. The second study was conducted to test the effect of increased viewpoint separation on tolerance of vertical disparity. The results corroborated expectations that increased viewpoint separation would reduce vertical disparity tolerance. Guidelines are given for future modifications and system implementation.
