Observation of tower vibration based on subtle motion magnification

Abstract

The vibration of the tower will cause fatigue damage of the tower, reduce the bearing performance of the tower, and result partially damage of the tower. It is difficult to implement and maintenance for the traditional contact measurement method. Motivated by this fact, we propose a non-contact method to measure the vibration of the tower. We apply the video subtle motion magnification algorithm to the tower vibration observation. By processing the video sequence of the tower, we can directly observe the tiny movement of the tower using the naked eye without complicated sensor equipment. The proposed method is used Eulerian Video Magnification technology which processes the image as a whole to reduce computational cost and make the processed image real.
