Abstract
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.
