Knott Laboratory provides forensic engineering and animation, Civil & Structural, and Fire & Explosion Investigation services to reconstruct accidents.
Photogrammetry
The science of obtaining accurate 3D measurements from photos
Photogrammetry places 2D photographs into a 3D space using the fundamental principle of triangulation. Key points within a photograph can be matched to the same points from other photographs, aerial imagery, a 3D laser scan, or an accurate 3D model to determine the orientation and placement of photographs. This process utilizes the information the photographs contain to get an accurate representation of 3D space. For example, if an accident reconstructionist or engineer wants to find out how much deformation a vehicle has sustained, Photogrammetry can get the precise data the engineer needs to strengthen his or her analysis and opinion.
By matching our 3D data to data in photographs, our team can determine the position of vehicles, the location of important evidence, and measurements of evidence, such as tire marks or gouge marks. This technique is essential in obtaining accurate information to prepare engineering analysis and demonstrate the accuracy of our data. Photo matching can also be used to create more realistic animations by animating 3D vehicles and objects over photographs.

I wanted to personally thank you for all of your hard work and dedication in helping to get the case successfully resolved. If not for your hard work, your expert opinions and your keen analysis on this case, we would never have been able to settle it for the amount and/or in the time frame in which we did. It was truly a team victory.T.W., Attorney, Illinois

I am a Community Association Manager and have had a few opportunities to work with Knott Labs and each time I could not be more impressed. They are very professional and down to earth, they really take into account their client and want to do what is best for them. When I need an engineer Knott (Cade) is always the first call I make!Anonymous

I want to express our continued admiration for the quality of Knott Lab’s work both in accident reconstruction & in the preparation of demonstrative evidence. On the basis of your deposition testimony & the animation of the accident, the defense admitted the negligence of their employee, that it was the direct cause of the plaintiff’s injuries.D.W., Attorney, California

The work you did on the case was outstanding. Prior to going to the mediation, we sent your animation of what occurred to the defendants. I truly believe that your animation allowed the defense to see exactly what happened which, in turn, allowed them to appreciate their liability. Regardless, I think your work was outstanding and want to thank you.S.G., Attorney, Missouri

[Richard,].. Your assistance in the case has been invaluable. I am very pleased that you were able to rebut the findings of the two State Police officers and the defendants expert. No one else was sharp enough to focus on the oil spill in the photos and it was gone when the State Trooper did his final report.T.B., Attorney, Massachusetts
