Title:

    Calibrating a catadioptric light field array

Presenter(s)/Author(s):



Abstract:


    We present a new method for acquiring data for image-based rendering and 3D reconstruction using an array of spherical mirrors and a single high-resolution perspective camera. The main advantage of this setup is a wider field of view, but designing calibration and reconstruction algorithms is challenging because catadioptric systems with spherical mirrors have non-central viewpoints, and do not behave as perspective cameras. A single image from our perspective camera produces sample rays from a very large number of virtual viewpoints. In this sketch we describe the construction of this system and a new procedure for calibrating it.
