A Study of 3D Digitisation Modalities for Crime Scene Investigation

A valuable aspect during crime scene investigation is the digital documentation of scene. Traditional means include photography and in situ measurements from experts for further analysis. Although 3D reconstruction pertinent scenes has already been explored as a complementary tool pipelines, such technology considered unfamiliar not yet widely adopted. This explained by expensive specialised digitisation equipment that available so far. However, emergence high-precision but low-cost devices capable scanning or objects proven reliable alternative to their counterparts. paper summarises analyses state-of-the-art technologies using assesses usefulness typical police-related situations forensics domain general. We present methodology acquiring data various types scenes. Emphasis placed on applicability each technique wide range situations, ranging type size.

To support our findings, we release multi-modal dataset obtained hypothetical indoor public.
