Integrated survey methodology for the crime reconstruction

Abstract

The object of this study is to evaluate the applicability of photogrammetry and laser scanner techniques both on forensic ballistic reports and on reproduction of crime scene. In the first case, in a shooting range for small arms, photogrammetric and laser were used both for the acquisition of metric data related to the testing environment and for ballistic simulation on a suitable sample. The crime scene was specifically simulated in laboratory, while the room where a murder took place was re-created. Once the setting had been made, it was possible to perform the survey of the scene and the details in it by using laser scanner and photogrammetric techniques. Data acquisition has enabled authors to carry out a rapid reconstruction of the scene and detect several parameters using the available elements. Specifically, the processed data were also exported to a CAD and an image processing software.
