3D Forensics – Forensic Measurement, Analysis and Visualization 3D Forensic Reconstructions is a growing discipline in the field of forensics, but encompasses the use of total stations, laser scanners and photogrammetry to document crime and accident scenes in three dimensions. The resulting data can be analyzed and the environment can be reconstructed into a working model of the scene as it was at the time of the crime. Suspects, victims and physical evidence can be placed back in their respective positions and physical characteristics of different scenarios can be checked for consistency.
In reports IFS uses where necessary pictures of simulated scenarios. These are to support the report, because sometimes one single picture tells the reader more than a full page of text. Different theories are being tested for feasibility and a simulation of a crime scene or a certain position of a suspect in relation to a victim using 3D can give us new insights how a certain chain of events could have happened.
IFS is working closely with an 3D expert on international cases. Together we work as part of the investigative team to assist police, experts and attorneys with rebuilding a case from the ground up.
IFS is able to assist in the investigation of:
- Shooting Incident Reconstructions
- Crime Scene Recreations
- Vehicle Accidents
- Bloodstain Mapping
- Mapping of Bodily Injuries
- Patterned evidence
For some crime scene reconstructions IFS uses a new technique called ‘ motion capture ‘. This technique provided by Xsens is also used for video games and animated movies. With this technique, IFS is able to re-play an event very accurately and then project this in a virtual crime scene. By reconstructing and re-playing several possible scenarios, not only various hypotheses can be tested, but it can also directly be shown in a courtroom.
This is an example of a reconstruction of a couple arguing over a soda bottle which ended in a real fight….
The 2nd animation is just another example of a reconstruction of a fight where the victim was hit on the head with a hammer.
