| Outline of Final Research Achievements |
This study can build a highly reproducible 3D vehicle body model using the SfM method by taking pictures with a high lap rate (approximately 95% or more) from a high point (approximately 7 m or more). It was verified that the amount of deformation of the deformed vehicle body can be evaluated at approximately 5% (± 10 mm).
Moreover, analysis using the US accident database clarified the effect of roof deformation for occupant injuries in side impact collision. Based on the results, this study constructed an occupant injury prediction model that takes into account the amount of vehicle body deformation, and improved the prediction sensitivity to approximately 88% compared to the conventional prediction model.
