Using augmented-reality and mobile three-dimensional graphics techniques in relief work on radiological disaster sites

Many countries tightly manage and monitor various radio logical sources and facilities, yet some serious radiological disasters still occurred in recent decades. In order to reach effective relief work on radio logical disaster sites, numerous information techniques have become popular, i. e. global positioning system, geographical information system, computer simulation, and three-dimensional graphics. However, this study recognizes insufficient information service in global positioning system and geographical information system and inconvenient information operation in computer simulation and three-dimensional graphics. Therefore, this study adopts augmented-reality and mobile three-dimensional graphics techniques to construct a mobile re lief work system. This system helps relief workers to comprehend the spatial relationship among their localities, the targeted constructions, and the anticipated shelters. Based on the testing results regarding escaping victims, through the mobile relief work system in contrast to a Google maps-based system, relief workers more easily arrive at the targeted constructions, and more rapidly seek the anticipated shelters. In sum, this study is useful for similar applications in disaster management.
