Autocalibration of a camera pair

Abstract

Given a pair of cameras with identical intrinsic parameters and known pixel shape, there exists a uniparametric set of possible 3D Euclidean reconstructions. We provide for this set a closed-form explicit parameterization. Therefore, given a single piece of data from the scene, the set of solutions can be efficiently searched for the best-fit reconstruction. An experiment with real images, showing the applicability of the method, is included.
