View Estimation System from Moving Omni-Directional Stereo Camera

Abstract

Information on what a user can see and what he/she cannot see in the surrounding environments is one of the important clues to estimate his/her subjective states and predict the next action. Our previous study has proposed a system for estimating the user’s three-dimensional field of view by using multiple RGB-D cameras cooperatively. However, in the previous system, positions of the cameras must be known and fixed. Therefore, the system cannot estimate the user’s view from moving cameras. In this study, we propose a view estimation system using only one omnidirectional stereo camera to achieve a wide range estimation from a moving camera.
