Extracting Accurate Measurements from Single Surveillance Camera Images
06/15/2017 | Eugene Liscio
Applications: All and Forensics & Accident Recon.

PhotoModeler can solve important information about the single camera and the scene at the time of the crime, by using the image captured at the time of the crime, and combining that with 3D data captured after the crime.

In this paper a detailed method is described using PhotoModeler to ‘marry’ the detail of a 3D laser scan with one still from a security camera, and then exported to 3D Studio Max for further analysis.

Photogrammetric Documentation of Regions of Interest at Autopsy – A Pilot Study
08/03/2013 | Liselott Slot, Peter K. Larsen, Niels Lynnerup
J Forensic Sci, 2013, doi: 10.1111/1556-4029.12289
Applications: All, Biology, and Forensics & Accident Recon.

In this pilot study, the authors tested whether photogrammetry can replace or supplement physical measurements made during autopsies and, based on such measurements, whether virtual computer models may be applicable in forensic reconstructions.

A New Capability for Crash Site Documentation
2013 | Major Adam Cybanski, Directorate of Flight Safety, Ottawa
International Society of Air Safety Investigations Conference
Applications: All and Forensics & Accident Recon.

The author discusses the use of photogrammetry in aircraft accident scene documentation. Major Adam Cybanski is the officer responsible
for helicopter investigation at the Canadian Forces Directorate of Flight Safety in Ottawa, Canada. He is a tactical helicopter pilot with over 20 years and 2500 hours on fixed and rotary wing aircraft.

Return to the scene of the crime — in 3D
11/24/2011 | Tom Cheshire
Wired.co.uk
Applications: All and Forensics & Accident Recon.

Over the past four years, Liscio, based in Toronto, has worked on nearly 60 cases around the world. Police use his reconstructions to test their theories of a crime. “You can start running different scenarios — what would happen if this person was a little to the left: would the trajectory still work? Or could the witness have actually seen the suspect at that point?” Liscio uses off-the-shelf 3D scanning equipment, such as the PhotoModeler Scanner made by EOS, to map entire crime scenes.

The Accuracy of Photogrammetry vs. Hands-on Measurement Techniques used in Accident Reconstruction
04/12/2010 | Bryan Randles, Biomechanical Research & Testing; Brian Jones, Elliott & Jones LLC; Judson Welcher and Thomas Szabo, Biomechanical Research & Testing; David Elliott, Elliott & Jones LLC; and Cameron MacAdams, Elliott & Jones, LLC
SAE 2010-01-0065
Applications: All and Forensics & Accident Recon.

A study was conducted to assess the relative accuracy of two measurement techniques commonly used for vehicle measurements in damaged-based accident reconstruction. The traditional technique of hands-on measurement was compared with the use of photogrammetry for measurement of targeted damaged vehicles. Three undamaged vehicles were subjected to 4 impacts, resulting in 4 damaged areas (two front, one side and one rear).

Semi-Automated Crush Determination Using Coded and Non-Coded Targets with Close-Range Photogrammetry
03/01/2007 | Dan Mills and Gary Carty, DCM Technical Services Inc.
Accident Reconstruction Network
Applications: All and Forensics & Accident Recon.

Vehicle crush measurement (which is typically used to determine vehicle speed (or change in velocity : delta-v) at time of impact) has traditionally been done with tape measure or a surveyor’s total station. Mills and Carty demonstrate a method which is low cost, flexible, automated and accurate using PhotoModeler and PhotoModeler’s coded targets.

Person identification by gait analysis and photogrammetry
01/01/2005 | N. Lynnerup, Institute of Forensic Medicine, University of Copenhagen, Denmark, and J. Vedel, 3D Photo, Aarhus, Denmark
Journal of Forensic Sciences
Applications: All and Forensics & Accident Recon.

Using PhotoModeler and surveillance video, the authors perform measurements of height, and measurements of angle for gait analysis. Using this analysis the authors along with the police were able to correctly identify the perpetrator of a heinous crime. Complete study available to members – the external link shows abstract to all.

Determination and Verification of Equivalent Barrier Speeds (EBS) Using PhotoModeler as a Measurement Tool
03/08/2004 | Lara L. O'Shields and Tyler A. Kress, BEST Engineering; John C. Hungerford, Hungerford and Associates; and C. H. Aikens, The University of Tennessee
SAE 2004-01-1208
Applications: All and Forensics & Accident Recon.

The main objective of this study is to show that PhotoModeler is a suitable measurement tool for vehicle crush measurement in the context of determining the equivalent barrier speed (EBS). The PhotoModeler process is applied to controlled crash information generated by the NHTSA.
