Accident Scene Diagramming Using New Photogrammetric Technique

One of the challenges for accident reconstructionists is creating accurate accident scene diagrams from photographs, esp when only one photograph is available, and information about the camera that took the photograph is not available. The authors present a technique that enables the user to create an accurate accident scene diagram from only one unknown photograph of the accident scene, by using a combination of processes called Inverse Camera Projection and Photographic Rectification.
