Abstract(in English) | This paper presents a full and consistent theory for describing indeterminacy and uncertainty of 3-D reconstruction from a sequence of images. First, we give a formal description of the 3-D reconstruction problem and present a group-theoretical analysis of "gauge transformations" and "gauges" by invoking the Lie group theory. We then discuss how to evaluate the reliability of the solution that has indeterminacy. We derive the gauge transformation rule of covariance matrices and characterize "gauge invariants". We also extend the Cramer-Rao lower bound to problems with internal indeterminacy. Finally, we describe the "free-gauge approach" and the "canonical form" of a covariance matrix that is independent of particular gauges. |
