This project is aimed at testing the performance of 3D optical acquisition and reverse engineering to carry out the contact-less gauging of crime scenes for their documentation and analysis. In particular, the study focuses on two aspects. The former is the “in-field” measurement and modeling of crime scenes.

The latter is the analysis of lesions, organs, bone tissues and skin wounds during the legal-medicine inspection.
