Knott Laboratory provides forensic engineering and animation, Civil & Structural, and Fire & Explosion Investigation services to reconstruct accidents.


Video Matching

Match moving is primarily used to track the movement of a camera through a shot so that an identical virtual camera move can be reproduced in a 3D animation program


Matchmoving, also known as video tracking or video matching, is the photogrammetric process in which computer generated objects are placed within a video background.

Placing computer generated vehicles or objects into video results in highly realistic animations. In many cases, this technique is so compelling that it appears as though video was taken while the accident happened.

In addition to its uses in animation, match moving has proven to be a valuable tool for extracting 3D data from video. This data can be used to help determine distances and relationships between objects in the scene.

View Samples of our Work

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

High Profile Cases

Knott Laboratory has become the leader in forensic engineering and computer animation by investigating high profile cases and conveying our analysis effectively during litigation.

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.
