Abstract

The story drift angle has been recognized to have a close relationship with damage in the building. Several methods have been proposed using displacement sensors or corporative marker. However, they are costly. In this paper, a method using optical flow to estimate story drift angle is proposed. This method is simple and less costly. It was verified that the story drift angle was accurately obtained from the simulation tests.
