ViRoom - Low cost synchronized multicamera system and its self-calibration

Abstract

This paper presents a multicamera Visual Room (ViRoom). It is constructed from low-cost digital cameras and standard computers running on Linux. Software based synchronized image capture is introduced. A fully automatic self-calibration method for multiple cameras and without any known calibration object is proposed and verified by 3D reconstruction experiments. This handy calibration allows an easy reconfiguration of the setup. Aside from the computers which are usually already available, such a synchronized multicamera setup with six or seven cameras costs less than 1000 USD. © Springer-Verlag Berlin Heidelberg 2002.
