A multi-spectral sensor dedicated to 3D spherical reconstruction

This paper describes the development of an original stereoscopic sensor suitable for 3D spherical reconstruction Unlike the existing sensors, it uses four acquisition channels coupled with an additional structured light projector to obtain an accurate 3D spherical reconstruction with faithful colors. Real experiments demonstrate the feasibility of this new spherical sensor. This original sensor is dedicated to real scenes reconstruction for multimedia and motion pictures applications over 360/spl times/360 degrees.
