Vehicle deformations are important sources for information aboutthe performance of safety systems. Photogrammetry has developed vastly under recent years. In this study modern photogrammetrical methods have been used for vehicle deformation analysis. The study describes the equipment for documentation and recording in the field (semi-metric camera), and a system for photogrammetrical measurements of the images in laboratory environment (personal computer and digitizing tablet). The material used is approximately equal to 500 collected and measured cases. The study shows that the reliability is high and that accuracies around 15mm can be achieved even if the equipmentand routines used are relatively simple. The effects of further development using video cameras for data capture and ditigal images formeasurements are discussed. (A).
