Ground-Plane Based Projective Reconstruction for Surveillance Camera Networks
McKinnon, David N., Lakemond, Ruan, Fookes, Clinton B., & Sridharan, Sridha (2007) Ground-Plane Based Projective Reconstruction for Surveillance Camera Networks. In International Conference on Signal Processing and Communication Systems 2007, 17-19 December 2007, Gold Coast, Australia. (In Press)
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.

Citation countsare sourced monthly fromand 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
