Abstract

This paper examines the task of calibrating a network of security cameras of arbitrary topology utilizing a common ground-plane to simplify the geometry. The method of chaining ground-plane homographies is employed to overcome the necessity that a common region is visible in all images of the ground-plane. We show that this method of recovering a projective reconstruction is ideal for the case of surveillance camera networks due to the ability to linearly initialize the cameras and structure when making use of the common ground-plane assumption.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
