Abstract

The goal of an augmented reality system (ARS) is to superimpose in real time a real world scenery with a virtual extended version of itself. Such an ARS is, also developed as part of a disaster management tool of the collaborative research centre 461 (CRC461): "Strong Earthquakes". Rescue units are supposed to use the ARS as a tool to plan their actions on site using the possibilities offered by virtual reality. Regarding the reconnaissance strategy of the CRC461 there will be airborne laser scanning data collected of the whole affected area after an earthquake. This in turn means that the geometrical shape of the buildings is known. This threedimensional data can be fused with other information available, e.g., digital elevation model, building structure and so on. This information can now be used as planning information for rescue units. The construction, of such a system, is a challenge in many ways. Firstly, the proposed work shows how digital surface models can be used in different ways for the on site calibration of an SeeThrough Head-Mounted Display (STHMD) and the connected head tracking devices. Next to this the paper will introduce special possibilities offered by such a technology to analyse possible rescue plans for collapsed buildings in the context of disaster relief. On the other hand there is a set of primitive analysis techniques like measuring distances without touching the object directly.
