A measurement technology in which the 3D coordinates of points on an object are determined by measurements made in video images

Knott Laboratory uses the technique of videogrammetry to extract important information from video. A video is analyzed or matched up to scaled digital 3D objects to establish vehicle speeds or positions, and to determine the size of an object or person.

Videogrammetry is a practical method of measuring motion in 3D. Digital camcorders are used to film moving targets, then the targets are tracked and their positions calculated using custom software.

Knott Laboratory’s forensic engineers and animators have used videogrammetry in:

• Automobile and Truck crash tests
• Crane collapse
• Forklift accidents
• Motorcycle accidents
• Train accidents
• Vehicle rollovers

Since 1982, Knott Laboratory has been providing comprehensive forensic engineering and computer animation services to reconstruct accidents.

Experts in the Field

Our forensic engineers are experts in accident reconstruction, failure analysis and cause & origin. Our forensic engineers work directly with our in-house animation department to create state-of-the-art forensic animations for use in court, arbitration, mediation or settlement negotiations.
