Abstract

A condition monitoring method combining vision-based vibration measurement and two-dimensional motion analysis is proposed for floating wind turbines（FWTs）. It enables non-contact and precise measurements of the platform motions and the tower vibration of an FWT simultaneously. Virtual motion simulation videos show that the relative error of the proposed method is less than 1%. When the simulated visual video encounters strong noise interferences, the recognition errors of all other responses （except the floater pitch） is no more than 5%. Furthermore, the proposed method is applied to the motion/vibration recognitions of a FWT model test, further validating its feasibility and reliability.
