Dynamic and Occlusion-Robust Light Field Illumination

Abstract

There is high demand for dynamic and occlusion-robust illumination to improve lighting quality for portrait photography and assembly. Multiple projectors are required for the light field to achieve such illumination. This paper proposes a dynamic and occlusion-robust illumination technique by employing a light field formed by a lens array instead of using multiple projectors. Dynamic illumination is obtained by introducing a feedback system that follows the motion of the object. The designed lens array incorporates a wide viewing angle, making the system robust against occlusion. The proposed system was evaluated through projections onto a dynamic object.
