Authors Abstract
Content
A new optical system to analyse 3D deformations crashed vehicles is in use at Porsche’s Crash Test Facility. This technology is based on the mathematical law that the spatial location of a point is clearly definable if it is represented by at least 2 images. With the help of an high resolution digital camera, highly developed image processing and photogrammetric algorithms, an automated deformation analysis system is realized. This new measurement technology has numerous advantages over conventional devices, such as coordinate measurement machines, multi section arms and analog photogrammetry.
In one example of crash tests the application of this system is described. Comparisons with conventional measurement devices regarding accuracy, costs and process optimization are presented. An outlook to further innovations in analysis of safety tests, if photogrammetry is used as a basic technology, is given.
