Dynamic Non-contact 3D Measurement System for Rollover Testing

Photon-X is proposing to develop a 3D roof imaging system to monitor vehicle roof deformation during vehicle rollover testing. The system will provide photographic resolution imagery with the ability to track the dot pattern on the vehicle roof. The Photon-X spatial phase 3D imaging system will provide an accurate visible record of roof deformation with position accuracy of 1mm and velocity accuracy better than 0.1km/hr. The feasibility of the system has already been demonstrated for measuring the flatness of wings for the Air Force. The alogrithms for creating depth maps of surfaces exist, as does the 3Dimaging system that creates them. Using this system provides the DOT sponsor with a low-risk, low-cost approach to achieving the goal of this solicitation. At the conclusion of the proposed work Photon-X will provide a prototype DOT imaging system with the capability to operate in the 30G environment specified in this solicitation.
