Motion Capture Applications in Forensic Injury Accident Reconstruction 2007-01-2476
Forensic injury accident reconstruction is used to determine what happened in an accident, typically for use in a court of law. In order to be admitted as evidence in a trial, the analysis must be scientifically sound, and performed utilizing standard scientific methods. The use of motion capture methods for forensic biomechanical applications provides an accurate, scientifically proven technique that has advantages not only due to its technical capabilities, but also in its highly visual manner of result presentation. This paper illustrates the use of a near-infrared motion capture system in two different types of forensic biomechanics applications. In one case, motion capture was utilized to capture externally applied force data and synchronized with the three-dimensional human body posture to perform a musculoskeletal biomechanics analysis. In the other case, the motion capture system was used to determine the circumstances of impact trauma that was incurred in an asphalt roller accident.
