Creation of a dynamic three-dimensional model by “Structure from Motion” from multiple full HD movies of a full-scale shaking table test

Abstract

A full-scale shaking table test of Indonesian masonry houses conducted in NIED on June 5, 2014 was filmed with eight full HD movie cameras. 399 video frames were taken for each camera from the beginning of the shaking to the collapse of the building and processed by a SfM (Structure from Motion) software. The behavior of the model can be observed in chronological order from arbitrary viewpoints. SfM can be a powerful tool to observe the dynamic behavior of the whole surface of a model for shaking table tests.
