| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Lens arrays enable us to easily achieve inexpensive light field acquisition in comparison with massive camera arrays. However, their micro-lenses often cause insufficient exposure to obtain high quality multi-view videos like camera arrays. In this paper, we propose a novel virtual camera array acquiring dynamic light fields as multi-view videos robustly and inexpensively, where mirror arrays consisting of tangent planes to a paraboloid are effectively combined with a single video camera. First, we reveal that if designing virtual cameras with appropriate parameters, dynamic light fields of the 3D scene can be acquired with good quality by our proposed multi-view imaging system. Next, we theoretically clarify that there exists smooth extension of our mirror array along a paraboloid, that can be implemented easily by CNC machines, and so on. Finally, the proposed imaging system equipped with a simple prototype of our 2D mirror array demonstrates dynamic light field acquisition for 2D viewpoints equally-spaced in horizontal and vertical directions, where a one-way mirror is introduced to prevent the camera itself from appearing on multi-view images. | |
