Paper Abstract

We describe the principles of building a moving vision platform (a Rig) that once calibrated can thereon self-adjust to changes in its internal configuration and maintain an Euclidean representation of the 3D world using only projective measurements. The calibration paradigm is termed "Omni-Rig". We assume that after calibration the cameras may change critical elements of their configuration, including internal parameters and rotations. Theoretically we show that knowing only the relative positions between a set of cameras is sufficient for Euclidean calibration even varying focal length and unknown rotations. No other information of the world is required.
