摘要： High rates of urbanization, environmental degradation, and industrial development in disaster-prone areas have all served to increase the extent of damage following catastrophes. In this paper, we present a novel framework for exploiting multi-resolution dual cameras, including a wide-angle camera and a speed dome camera, to construct a wide-angle, multi-layered, high-resolution visual monitoring system for hazard assessment. Our two-part camera system requires calibration of the correspondence between the detailed and overview image captured by the speed dome camera and wide-angle fixed camera, respectively. In-factory calibration is carried out using white–black patterns for speed dome turning and multi-layered calibration. The results are displayed as wide-angle, multi-layered, high-resolution images which are built up by the speed dome camera. 其他題名： Nat Hazards 出版者： Dordrecht: Springer Netherlands 出版日期： 2013-02-01 出處： Natural hazards (Dordrecht), 2013-02, Vol.65 (3), p.1285-1292 資源來源： Agricultural & Environmental Science Collection 版權： Springer Science+Business Media Dordrecht 2012 版權： 2014 INIST-CNRS 版權： Springer Science+Business Media Dordrecht 2013 識別號： ISSN: 0921-030X 識別號： EISSN: 1573-0840 識別號： DOI: 10.1007/s11069-012-0409-9 識別號： CODEN: NAHZEL
