✦ Synopsis

In forensic investigations of disasters, it could be necessary to carry out a reconstruction of all movements made by people and cars just before, during, and after a big incident. The goal is to find not only perpetrators, but victims and eyewitnesses as well. Methods and technology are presented that are based on the widespread availability of video footage from CCTV systems and phone cams, and intelligence such as cell phone traffic data. Analysis of all video data is based on the concept of events on a time line and the use of 2-D maps, aerial photography, and 3-D city and terrain models. All methods and technology will be demonstrated with case data from capital crimes. The presented was carried out within the framework of a 3-year project. A brief overview is given of other results such as automated procedures for the analysis and technology for fast 3-D modelling from imagery.
