Statistical modelling of epipolar misalignment

Abstract

This paper presents a new system for tridimensional virtual drawing relying on an infrared pen observed by a number of surrounding cameras. Nintendo wiimotes are used as cameras to provide reliable real-time tracking information. Since 3D triangulation requires the pen to be visible from at least 2 cameras, which highly constrains the field of view, we support many wiimotes for accurate reconstruction over a large space, while providing maximum movement flexibility to a performer. The paper focus on the calibration of multi-wiimotes setups and accurate 3D reconstruction of trajectories. Tested with up to 6 wiimotes and used in real performance context, the system provides both accurate 3D tracking and great performance flexibility.
