The Application of Photogrammetry in the Autopsy Room: A Basic, Practical Workflow.

The Application of Photogrammetry in the Autopsy Room: A Basic, Practical Workflow. J Forensic Sci. 2020 Jun 30;: Authors: Gitto L, Donato L, Di Luca A, Bryant SM, Serinelli S Abstract Photogrammetry is a technique that uses two-dimensional photographs taken from different angles and positions to determine three-dimensional coordinates and distances. Becoming familiar with the photography technique for photogrammetry purposes is the first step to obtaining high-quality results. Ten human cadavers were studied to develop this protocol. Appropriate equipment settings, measurements, and suitable ambient conditions were determined. Finally, the protocol was tested on one cadaver wherein a full postmortem examination was conducted, allowing accurate 3D modeling and measurements of the human body. This straightforward, step-by-step workflow will help users become familiar with this technique. A thorough description of the necessary steps is reported, including equipment, environment requirements, body placement, how to take photographs, and the minimum suggested number of photographs. Numerous graphics show the protocol's main steps to help users understand and reproduce the entire process. Photogrammetry allows the permanent recording and storage of photographic evidence of conditions that existed at the time of autopsy and accurate measurements of the body. The 3D model can have a powerful effect in court, where the findings can be accur...
