Paper Abstract

A new method using cameras as transducers to measure the bridge displacement and vibration is developed. The method and corresponding system have the advantages of non-contact, high accuracy. Also it can dynamically measure the displacement and then derive the vibration parameters of the bridge. The accuracy of the optical measurement system can reach to 0.017mm.
