We propose a distributed algorithm for camera network localization based on feature point correspondences between multiple cameras with sparse overlapping view structure. We prove convergence of the iterative piecewise-linearized algorithm using the projection onto convex sets (POCS) principle, since this algorithm corresponds to projecting onto subspaces that approximately overlap. We provide bounds on convergence rates and worst-case errors and show experimental results from actual images. Finally, we introduce a new technique to obtain initial localization estimates based on trajectory observations.62 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
