Computer-aided 3-d surface reconstruction during high speed crush events.

A system which can remotely measure detailed deformations of vehicle structures during crush events was developed. The system uses ordinary video or 16 mm high speed movie to capture the crush event. This information is digitized and analyzed using personal computers to perform photogrammetric manipulations which yield accurate surface geometries. The output is useful for comparison to computer simulations. This paper presents preliminary results regarding the accuracy of this system.
