Videogrammetry System for Wind Turbine Vibration Monitoring

Early detection of component failure in wind turbines pro- duces a great value in savings. We present an external method for obtain- ing the tower vibrations using videogrammetry. We use a multi-view image acquisition system and a set of fiducial markers set on the surface of the tower. Targets are identified using a radial symmetry measure, their centre is located through elliptical model fitting, and they are recog- nized through a standard segmentation and decoding method. Finally targets are tracked and displacements processed. We have obtained good results in the tests performed and we intend to continue gathering data to build a classification system for identifying abnormal vibrations.
